This article provides an outline of the classification of the kingdom Fungi (including fossil fungi. i.e. dispersed spores, mycelia, sporophores, mycorrhizas). We treat 19 phyla of fungi. These are Aphelidiomycota, Ascomycota, Basidiobolomycota, Basidiomycota, Blastocladiomycota, Calcarisporiellomycota, Caulochytriomycota, Chytridiomycota, Entomophthoromycota, Entorrhizomycota, Glomeromycota, Kickxellomycota, Monoblepharomycota, Mortierellomycota, Mucoromycota, Neocallimastigomycota, Olpidiomycota, Rozellomycota and Zoopagomycota. The placement of all fungal genera is provided at the class-, order- and family-level. The described number of species per genus is also given. Notes are provided of taxa for which recent changes or disagreements have been presented. Fungus-like taxa that were traditionally treated as fungi are also incorporated in this outline (i.e. Eumycetozoa, Dictyosteliomycetes, Ceratiomyxomycetes and Myxomycetes). Four new taxa are introduced: Amblyosporida ord. nov. Neopereziida ord. nov. and Ovavesiculida ord. nov. in Rozellomycota, and Protosporangiaceae fam. nov. in Dictyosteliomycetes. Two different classifications (in outline section and in discussion) are provided for Glomeromycota and Leotiomycetes based on recent studies. The phylogenetic reconstruction of a four-gene dataset (18S and 28S rRNA, RPB1, RPB2) of 433 taxa is presented, including all currently described orders of fungi., Nalin N.

The main aims of this work were to assess phylogenetic relationships of the trentepohlialean photobionts in tropical, mainly sterile, lichens collected in Bolivia, to examine their genetic diversity, host specificity, and the impact of habitat factors on the occurrence of Trentepohliales. Based on rbcL marker analysis, we constructed a phylogenetic tree with eight major clades of Trentepohliales, of which seven free-living species are intermingled with lichenized ones. Our analyses show that the studied photobionts are scattered across the phylogenetic tree and algae from temperate and tropical regions do not form monophyletic groups, except within one clade that seems to be restricted to the tropics. There is no significant occurrence pattern of lichenized Trentepohliaceae on a specific substratum, except Cephaleuros spp. and Phycopeltis spp., which are restricted to leaves, while some clades with lichenized algae may be specialized to tree bark and wood. Moreover, we found two patterns of associations: first, closely related algae can associate with distantly related mycobionts; second, some other trentepohlioid algae associate with selected lineages of fungi (e.g., Arthoniaceae or Graphidaceae). We also found that some lineages of photobionts are even more selective and associate exclusively with one species (e.g., Dichosporidium nigrocinctum, Diorygma antillarum) or closely related lichen-forming fungi (Herpothallon spp.). Concluding, we found that occurrence of some trentepohlialean photobionts may correlate with the particular type of the mycobiont.

Lichen-inhabiting fungi are highly specialized mycoparasites, commensals or rarely saprotrophs, that are common components of almost every ecosystem, where they develop obligate associations with lichens. Their relevance, however, contrasts with the relatively small number of these fungi described so far. Recent estimates and ongoing studies indicate that a significant fraction of their diversity remains undiscovered and may be expected in tropical regions, in particular in hyperdiverse fog-exposed montane forests. Here, we introduce the new genus Zhurbenkoa, from South America and Europe, for three lichenicolous fungi growing on thalli of the widespread lichen genus Cladonia (Lecanorales). Phylogenetic analyses based on combined sequence data of mt and nuc rDNA obtained from Andean populations (Bolivia) placed Zhurbenkoa as a member of Malmideaceae, a recently introduced family of lichen-forming fungi in the class Lecanoromycetes. Zhurbenkoa is closely related to the genera Savoronala and Sprucidea. The new genus is characterized by the development of grayish brown to almost black apothecia lacking an evident margin, an epihymenium interspersed with crystals (often seen as pruina), a strongly conglutinated hymenium made of noncapitate and sparsely branched paraphyses, a colorless exciple composed of radially arranged hyphae, a Lecanora/Micarea-like ascus type, and aseptate or 1-septate ellipsoidal colorless ascospores. Zhurbenkoa includes two Neotropical (Z. cladoniarum, Z. latispora) and one widespread (Z. epicladonia) species. The lichenicolous trophic mode is documented for the first time in the Malmideaceae, which until now included only lichen-forming associations between fungi and green algae., This research was financially supported by the National Science Centre (NCN) in Poland (DEC-2013/11/D/NZ8/03274).

This paper presents seven freshwater lichen species from Western Carpathian streams: Bryobilimbia ahlesii (Körb.) Fryday et al., Rhizocarpon sublavatum Fryday, Thelidium circumspersellum (Nyl.) Zschacke, T. klementii Servít, T. pluvium Orange, T. rehmii Zschacke and Verrucaria devensis (G. Salisbury) Orange. All of them are first records for Poland. Thelidium klementii is new for the Carpathians and was previously known only from the type locality in Germany. Morphological descriptions based on Polish specimens are presented, and the ecology and geographical distribution of these lichens are briefly discussed.

A new coprinoid fungus, Coprinopsis rugosomagnispora, is described from Poland (Central Europe). Its macromorphological characters are similar to species belonging to the subsection Nivei of Coprinus s.l. However, C. rugosomagnispora has unique micromorphological characters: very large, ornamented spores, voluminous basidia and cystidia, and smooth veil elements. The large spores and pattern of spore ornamentation (densely pitted) make this species unique within all coprinoid species described so far. The structure (arrangement and shape) of veil elements in C. rugosomagnispora is intermediate between members of the subsections Nivei and Lanatuli of Coprinus s.l. Molecular phylogenetic analyses, based on single-locus (ITS) maximum likelihood and Bayesian evolutionary trees recovered C. rugosomagnispora within a lineage containing species having morphological characters of the subsection Lanatuli (though within the so-called Atramentarii clade) that contradicts its morphological similarity to members of the subsection Nivei.

Printzen, C., Halda, J. P., McCarthy, J. W., Palice, Z., Rodriguez-Flakus, P., Thor, G., Tonsberg, T. & Vondrak, J. 2016. Five new species of Biatora from four continents. — Herzogia 29: 566–585. Biatora australis and B. hafellneri from South America, B. pacifica from East Asia, B. radicicola from central and northern Europe and the Caucasus, and B. terrae-novae from Newfoundland are described as new to science. The phylogenetic position of four of these species is reconstructed using ITS and mrSSU sequence data. Revised identification keys for the Biatora vernalis group and Biatora species with non-septate ascospores and blue or green apothecial pigments are also provided.

Members of the lichen genus Lecanora Ach. are important but still poorly known components of almost all vegetation types in Bolivia. In this paper, seven species new for Bolivia are presented: Lecanora bicincta Ramond, L. fulvastra Kremp., L. hagenii (Ach.) Ach., L. muralis (Schreb.) Rabenh., L. percrenata H. Magn., L. stramineoalbida Vain. and L. strobilina (Spreng.) Kieff. Their distributions are described and information on their diagnostic characters and chemistry is given

The present treatment shows that the lichen family Trypetheliaceae is an important component of lowland and montane tropical forests in Bolivia. A total of 75 species are currently recognized in Bolivia, of which 24 are new to science and a further 37 are reported for the first time from the country. The following species are described: Architrypethelium penuriixanthum Flakus & Aptroot sp. nov. that differs from A. hyalinum in the lack of lichexanthone in the thallus; Astrothelium amylosporum Flakus & Aptroot sp. nov. that differs from A. subdisjunctum in having 8-spored asci and amyloid ascospores; A. bullatum Flakus & Aptroot sp. nov. that differs from A. megaspermum in having a bullate thallus, a clear hamathecium, 8-spored asci and smaller amyloid ascospores; A. carrascoense Flakus, Kukwa & Aptroot sp. nov. that differs from A. meristosporum in having broader ascospores without distinctly thickened median septa, an unidentified xanthone as major substance, and mostly eccentric ostioles; A. elixii Flakus & Aptroot sp. nov. that differs from all other Astrothelium species in the presence of lichexanthone in the outer layer of thallus and pseudostromata and isohypocrellin inside the pseudostromata, and muriform ascospores; A. inspersotuberculosum Flakus & Aptroot sp. nov. that differs from A. tuberculosum in having an inspersed hamathecium; A. megaeneum Flakus & Aptroot sp. nov. that differs from A. croceum in having a thallus covered by parietin, and mostly fused ascomata with intermediate, fused to separated ostioles surrounded by a common ostiolar area; A. neodiplocarpum Flakus, Kukwa & Aptroot sp. nov. that differs from A. diplocarpum in the absence of medullary pigment and in the amyloid ascospores; A. nigrocacuminum Flakus, Kukwa & Aptroot sp. nov. that differs from A. megochroleucum in having fused, eccentric ostioles and black (UV−) tops of the pseudostromata; A. pallidoflavum Flakus & Aptroot sp. nov. that differs from A. cinnamomeum in having wider ascospores; A. pyrenuliforme Flakus & Aptroot sp. nov. that differs from A. ecuadoriensis ecuadoriense in having shorter ascospores and in the presence of pseudocyphellae; A. subscoria Flakus & Aptroot sp. nov. that differs from A. scoria in having non-aggregated ascomata; A. variabile Flakus & Aptroot sp. nov. that differs from A. ochroleucoides in the longer ascospores; Bathelium boliviense Flakus & Aptroot sp. nov. that differs from B. lineare in the presence of isohypocrellin inside the pseudostromata; B. flavostiolatum Flakus & Aptroot sp. nov. that differs from all other Bathelium species in the presence of lichexanthone near the ostioles (tops of pseudostromata UV+ yellow) and an orange (K+ carmine red) pigment inside the pseudostromata, the absence of lichexanthone in the thallus, an inspersed hamathecium, and 13–17-septate ascospores; B. inspersomastoideum Flakus & Aptroot sp. nov. that differs from B. mastoideum in having an inspersed hamathecium; B. mirabile Flakus, Kukwa & Aptroot sp. nov. that differs from other Bathelium species in the pseudostromata containing isohypocrellin inside and parietin outside; B. pruinosum Flakus, Kukwa & Aptroot sp. nov. that differs from Astrothelium ochroleucoides in having 8-spored asci, shorter ascospores, an inspersed hamathecium, and an unidentified anthraquinone (orange pigment K+ carmine red) inside the pseudostromata; Constrictolumina chiquitana Flakus, Kukwa & Aptroot sp. nov. that differs from other known Constrictolumina species in having brown and 1-septate to submuriform ascospores; Dictyomeridium lueckingii Flakus & Aptroot sp. nov. that differs from D. proponens in having smaller and less septate ascospores; Polymeridium xanthoexcentricum Flakus & Aptroot sp. nov. that differs from P. alboflavescens in having mostly eccentric ostioles; Pseudopyrenula flavosuperans Flakus & Aptroot sp. nov. that differs from P. superans in having a hamathecium inspersed with yellow oil globules; Trypethelium astroideum Flakus & Aptroot sp. nov. that differs from T. subeluteriae in having K+ carmine red pseudostromata containing parietin inside and black tops with an additional unidentified anthraquinone (rust-red pigment K+ purple, UV−) on the outside, partly fused ostioles, and larger ascospores; and T. xanthoplatystomum Flakus & Aptroot sp. nov. that differs from T. platystomum in the presence of lichexanthone in the thallus.

In our ongoing study of the genus Cladonia, we have encountered several specimens that have proved to represent undescribed species. Four of them are described here as new. Cladonia camerunensis (Cameroon) resembles C. didyma (Fée) Vain., but the former has a coarsely granular surface and a melanotic podetial base; C. compressa (Bolivia) is distinguished by a dominant primary thallus and deeply divided and phyllopodiate podetia; C. longisquama (Seychelles) has well-developed squamules and contains barbatic acid; C. vescula (Bolivia, Peru) differs from C. peziziformis (With.) J. Laundon by an ecorticate podetial surface and the production of homosekikaic acid. The names C. aspera Ahti & Kashiw. and C. crinita (Delise ex Pers.) Ahti are shown to be illegitimate later homonyms and are replaced by the names C. asperula and C. perfoliata, respectively. The neglected name C. botryoides (Tuck.) Vain. is shown to be a synonym of C. squamosa. Another overlooked name, C. crinita Bertol., is shown to be the earliest name for C. evansii, but we propose to retain the latter through conservation. The typification of C. beaumontii Tuck. is amended. Cladonia conspicua is reinstated on the basis of new data. New range extensions in Canada and the United States are given for the poorly documented species C. oricola.

Fuscidea multispora Flakus, Kukwa & Rodr. Flakus and Malmidea attenboroughii Kukwa, Guzow-Krzeminska, Kosecka, Jablonska & Flakus are described as new to science based on morphological, chemical and molecular characters. Lepra subventosa var. hypothamnolica is genetically and chemically distinct from L. subventosa var. subventosa and a new name, Lepra pseudosubventosa Kukwa & Guzow-Krzeminska, is proposed due to the existence of Lepra hypothamnolica (Dibben) Lendemer & R.C. Harris . Pertusaria muricata , recently transferred to Lepra , is kept in the genus Pertusaria due to the highest similarity of ITS sequence with members of Pertusaria . The occurrence of Micarea hedlundii in the Southern Hemisphere is confirmed based on molecular evidence from Bolivian population. Lepra pseudosubventosa and Pertusaria muricata are reported as new to South America, and 20 taxa as new to Bolivia. Lepraria stephaniana , previously known only from the type locality, is reported from two more sites. An ascosporic state is reported for the first time for Lepra amaroides , as are new chemotypes. Molecular markers were used to place some sterile, sorediate crustose lichens in the family Graphidaceae. The phylogenetic positions of some sterile Malmidea specimens within Malmidaceae are also discussed.

The paper presents new records for four taxa of Ochrolechia A. Massal. from Bolivia, of which three, O. austroamericana (Räsänen) Räsänen, O. subpallescens f. Verseghy uruguayensis Verseghy and O. upsaliensis (L.) A. Massal., are new for the country. Ochrolechia subpallescens f. uruguayensis is shown to differ chemically from O. subpallescens s.str., but its taxonomic rank needs to be clarified with molecular studies. Ochrolechia africana Vain. is also reported for the first time for Tanzania and Uruguay, and O. austroamericana for Ecuador.

Farkas, E. & Flakus, A. 2015. Rare or overlooked? — Two species of Lyromma (Lyrommataceae, lichenized Ascomycota) are new for Africa. — Herzogia 28: 204–211. Two species of the foliicolous lichenized genus Lyromma so far known only from the Neotropics are reported for the first time from Africa. Lyromma multisetulatum, described from Bolivia and Brazil, was found recently in Kenya and Tanzania, and L. pilosum in Tanzania. Tanzanian specimens were discovered in lowland rainforest collections from 200 to 500 m altitude. The Kenyan collection originates from moist montane forests at c. 2000 m elevation. Both species are characterized by both perithecia and pycnidia observed on the same thallus. The distribution and frequency of these taxa are briefly discussed, and compared to other taxa with similar distribution patterns.

Pertusarialean lichens include more than 300 species belonging to several independent phylogenetic lineages. Only some of these phylogenetic clades have been comprehensively sampled for molecular data, and formally described as genera. Here we present a taxonomic treatment of a group of pertusarialean lichens formerly known as "Pertusaria amara-group", "Monomurata-group", or "Variolaria-group", which includes widespread and well-known taxa such as P. amara, P. albescens, or P. ophthalmiza. We generated a 6-locus data set with 79 OTUs representing 75 species. The distinction of the Variolaria clade is supported and consequently, the resurrection of the genus Lepra is followed. Thirty-five new combinations into Lepra are proposed and the new species Lepra austropacifica is described from mangroves in the South Pacific. Lepra is circumscribed to include species with disciform ascomata, a weakly to non-amyloid hymenial gel, strongly amyloid asci without clear apical amyloid structures, containing 1 or 2, single-layered, thin-walled ascospores. Chlorinated xanthones are not present, but thamnolic and picrolichenic acids occur frequently, as well as orcinol depsides. Seventy-one species are accepted in the genus. Although the distinction of the genus from Pertusaria is strongly supported, the relationships of Lepra remain unresolved and the genus is tentatively placed in Pertusariales incertae sedis.

The new obligately lichenicolous fungus, Melaspilea tucumana Flakus, Etayo & Kukwa, inhabiting thalli of saxicolous Pertusaria s. lat. is described from Tucumano-Boliviano vegetation in Bolivia. The species is characterized by the gall formation and superficial, lirelliform to branched, aggregated apothecioid ascomata with widely exposed discs. The ascomata of M. tucumana are initially perithecioid and immersed in the host thallus, but become superficial and apothecioid when mature, and thus resemble the genus Buelliella. This may suggest the placement of the new species in Dothideomycetes.

Kukwa, M., Schiefelbein, U. & Flakus, A. 2013. A contribution to the lichen family Graphidaceae (Ostropales, Ascomycota) of Bolivia. - Herzogia 26: 231–252. Carbacanthogr aphis violaceospora Kukwa & Flakus, Graphis boliviana Kukwa & Flakus and G. seawardii Flakus & Kukwa are described as new to science from Bolivia. In addition 56 corticolous and muscicolous species of Graphidaceae are reported for the first time from Bolivia, of which four, Graphis pinicola, G. urandrae, Phaeographis dendroides and P. quadrifera, are new to South America, and six, Graphis argentata, G. litoralis, G. nudaeformis, G. pittieri, G. subflexibilis and Phaeographis delicatula, are new to the Southern Hemisphere. Notes on the chemistry, habitat and general distribution are provided, with taxonomic remarks provided for some species.

Non-saxicolous lecideoid lichens form a diverse and polyphyletic group of species with a worldwide distribution. The phylogenetic relationships of the taxa and major clades are still largely unresolved. Here we introduce a new genus Palicella Rodr. Flakus & Printzen for Lecidea glaucopa Hook. f. & Tayl. and two closely related species. Our molecular phylogenetic results, based on maximum likelihood and Bayesian phylogenetic trees, and a combined dataset of five gene loci (ITS, nrLSU, mrSSU, RPB1 and RPB2), indicate that Palicella forms a monophyletic clade sister to Lecanora symmicta and Pyrrhospora quernea. The new genus is characterized by biatorine apothecia, which are often darkened (by the pigment Cinereorufa-green), an exciple of radiating, narrow hyphae with strongly elongate lumina, a hymenium with branched and sparsely anastomosed paraphyses, an ascus with a broad axial body surrounded by a distinct darker staining layer, and narrowly ellipsoid ascospores. Atranorin is present in all, usnic acid in two and pannarin in one species of the genus. Three new combinations are proposed: Palicella filamentosa (Stirt.) Rodr. Flakus & Printzen, P. glaucopa (Hook. f. & Taylor) Rodr. Flakus & Printzen, and P. schizochromatica (Pérez-Ortega, T. Sprib. & Printzen) Rodr. Flakus & Printzen. The molecular phylogenetic analysis confirms that Lecidea hercynica Hauck & Schmull is a synonym of P. filamentosa. An identification key to the species is provided.

New records of five lichenized fungi from Poland are provided. Hypotrachyna afrorevoluta, Lecanora quercicola, Rhizocarpon superficiale and Strigula ziziphi are new to Poland. Of these, Strigula ziziphi is reported also as new to Central Europe and Hypotrachyna afrorevoluta as new to the Carpathians. Additionally, Thelenella muscorum var. octospora is recorded from its second locality in Poland as new to the Polish Carpathians. Hypostictic acid chemosyndrome has been noticed for the first time in European (Poland) and South American (Bolivia) populations of Rhizocarpon superficiale.

In addition 56 corticolous and muscicolous species of Graphidaceae are reported for the first time from Bolivia, of which four, Graphis pinicola, G. urandrae, Phaeographis dendroides and P. quadrifera, are new to South America, and six, Graphis argentata, G. litoralis, G. nudaeformis, G. pittieri, G. subflexibilis and Phaeographis delicatula, are new to the Southern Hemisphere. Notes on the chemistry, habitat and general distribution are provided, with taxonomic remarks provided for some species.

The new lichenicolous Capronia paranectrioides Etayo, Flakus & Kukwa, inhabiting thalli of Erioderma leylandii, is described from Bolivia. The species is characterized by pale brown, submuriform and bicaudate ascospores, subglobose to barrel-shaped perithecia and I+ red, K/I+ pale blue hymenial gelatine. It is the first known Capronia species producing ascospores with long apical appendages.

Niesslia echinoides Etayo, Flakus & Kukwa sp. nov. is described from Bolivia from the corticolous thallus of Erioderma barbellatum. The fungus is characterized by large ascospores usually breaking into halves within the asci, strongly setose and aggregated ascomata, usually simple setae, and no damage caused to the host thallus.

A new gall-inducing lichenicolous fungus, Plectocarpon stereocaulicola Kukwa, Etayo and Flakus, is described from Bolivia from the thalli of Stereocaulon sp. The new species is characterized by black, epruinose rounded ascomata with a carbonized surface and a thalline pseudo-margin, as well as a non-carbonized, light brown sterile stromatic tissue in the lower part and 3-septate ascospores becoming brown and ornamented when mature.

Four new species of lichenicolous fungi are described from Bolivia: Capronia etayoi Flakus & Kukwa sp. nov. (on Dictyonema minus), Lichenosticta jurgae Kukwa & Flakus sp. nov. (on Lecanora sp.), Phaeosporobolus trypethelii Flakus & Kukwa sp. nov. (on Trypetheliumochroleucum; the host lichen new to Bolivia) and Spirographa usneae Flakus, Kukwa & Etayo sp. nov. (on Usnea sp.; also known from Ecuador).

The foliicolous lichenized fungus Calopadia erythrocephala Farkas, Elix & Flakus, is described as new to science from the Atlantic submontane rainforests in Brazil. The species is very similar to C. puiggarii, but is distinguished by the presence of a red pigment in the campylidia, the darker apothecial discs and larger conidia. Fusarubin, the red pigment produced by the new species, is reported for the first time from foliicolous lichens. A world-wide key to foliicolous species of Calopadia with single, muriform ascospores is presented.

Two new corticolous lichen species are described,Lepraria nothofagiElix & Kukwa (atranorin, strepsilin, porphyrilic acid) from Argentina andL. stephanianaElix, Flakus & Kukwa (4-O-methylleprolomin, zeorin, salazinic acid, unknown terpenoid) from pre-Andean Amazon forest of Bolivia. In addition, the paper presents new records of 16 species ofLeprariafrom South America.Lepraria adhaerens, andL. diffusaare new to the Southern Hemisphere;L. borealisis new to South America;L. alpinais new to Chile, Colombia, Peru and Venezuela;L. caesioalba(chemotype I) is new to Venezuela,L. lobificansnew to Argentina,L. pallidanew to Peru, andL. sipmaniananew to Bolivia and Chile. The Chilean records ofL. membranaceaappeared to belong toL. sipmaniana. Therefore, the number ofLeprariaspp. known at present from South America is enlarged to 27 species. 4-O-methylleprolomin is reported for the second time from lichens.

A new lichenized fungus, Lecanora microloba Śliwa & Flakus, is described from the subnival belt of the Polish Tatra Mountains. It is characterized by small, saxicolous thalli with minutely lobulate marginal areoles and mostly broadly sessile and constantly pale coloured apothecia that are grouped predominantly in the centre of the thallus. Anatomically the species is distinguished by coarse granules in the epithecium which are distinctly bright in polarized light. The species contains gyrophoric and usnic acids, zeorin and an unknown terpene as secondary metabolites.

In this paper three new species of Plectocarpon , P. dimorphosporum (on Ricasolia patinifera ), P. parmotrematis (on Parmotrema reticulatum ) and P. ramalinae (on Ramalina celastri ), are described from tropical montane forests in the Bolivian Andes. Plectocarpon dimorphosporum is characterized by strongly convex ascomata covered by the host cortex when young, presence of Atra-brown pigment and 1–3-septate ascospores developing a brown-pigmented granular perispore, P. parmotrematis by rounded and slightly superficial ascomata, presence of pigments reacting K+ aeruginose to turquoise and colorless 3-septate ascospores, and P. ramalinae by ellipsoid, black ascomata, Atra-brown pigment, and short, colorless, 3-septate ascospores. In addition, the rare Protounguicularia fasciculata is reported here for the first time from Bolivia.

Acarospora ramosa K. Knudsen & Flakus is described as new to science from the Bolivian Andes. It is characterized by a yellow, epruinose, rugulose thallus with a distinct effigurate margin, punctiform apothecia, and thin, branching and anastomosing paraphyses. The main diagnostic substances the new species produces are rhizocarpic and gyrophoric acids.

The corticolous lichenized fungus Aspidothelium lueckingii Flakus is described and illustrated as new to science from the montane cloud forest in Bolivia. It is characterized by pale perithecia with seta-like appendages and large, regularly muriform ascospores. The species is the sixth known member of the genus producing muriform ascospores. A key to all known species of Aspidothelium with muriform ascospores is provided.

The paper deals with 18 species of the lichen genus Cladonia, including eight species new to Bolivia: C. cf. borbonica, C. coccifera, C. confragosa, C. dactylota, C. granulosa, C. kriegeri, C. merochlorophaea, and C. squamosa. Furthermore, C. kriegeri is recorded here from its second and third localities in the world. Also five lichenicolous fungi are reported; among them Arthrorhaphis aeruginosa, Polycoccum microcarpum and Sphaerellothecium cladoniae are new to the southern hemisphere, and Roselliniella cladoniae and Tremella cladoniae are new to Bolivia. Additionally, Polycoccum microcarpum is reported for the first time from Slovakia and Ukraine. Cladonia confragosa is reported as a new host for Sphaerellothecium cladoniae and Tremella cladoniae.

Six new species of foliicolous lichenized fungi are described as new to science from Bolivian lowland Amazon forest: Asterothyrium vezdae Flakus & Lücking (Asterothyriaceae), Keratosphaera multiseptata Flakus & Lücking (Pseudoperisporiaceae), Phylloblastia bielczykiae Flakus & Lücking (Verrucariaceae), Porina boliviana Flakus & Lücking (Porinaceae), Tapellaria intermedia Flakus & Lücking (Pilocarpaceae) and Trichothelium subargenteum Flakus & Lücking (Porinaceae). In addition, new records of 70 lichen species in Bolivia are listed. Of these, 52 are new to Bolivia.
