Clavariadelphus species (Clavariadelphaceae, Gomphales) in China were examined using morphology, molecular phylogenetic analyses of ITS data and chemical reactions. Eleven taxa were identified in China, including four species known previously to occur in China (C. griseoclavus, C. ligula, C. sachalinensis and C. yunnanensis), two new record species from China (C. elongatus and C. himalayensis), four novel species (C. alpinus, C. amplus, C. gansuensis and C. khinganensis) and one species that could not be described due to the paucity of material. Finally, we also provided a taxonomic key for the identification of Clavariadelphus species in China.

Studies have demonstrated that many cosmopolitan species actually consist of divergent clades that present high levels of morphological stasis throughout their evolutionary histories.Phallus indusiatuss.l. has been described as a circum-tropical species. However, this distribution may actually reflect the lack of taxonomic resolution due to the small number of diagnostic morphological characters, which leads to the identification of new records as populations ofP. indusiatus. Here, we examine the diversity ofP. indusiatus-like species in Brazilian Amazonia. We show a clear congruence between detailed morphological data and ITS, nuc-LSU andatp6 based phylogenetic analyses and three new species are described within the Brazilian indusiate clade. These results highlight the importance of more detailed investigation, with the inclusion of molecular information, in Neotropical fungi.

Based on morphological and molecular analysis, we describe the new species Geastrum verrucoramulosum, discriminated from other species in the section Exareolata mainly by an elongated, verrucose, branched stipe. This new species is currently known from two forest locations in central and southwestern Amazonia. Species description, images, and taxonomic discussion of both morphological and molecular data are provided., The authors also thank the funding agencies Conselho Nacional de Desenvolvimento Cientı´fico e Tecnol ogico (MCTIC/PCI 300775/2016-4, Universal 473422/2012-3 and PVE 407474/2013-7), and Fundac¸ ~ao de Amparo a Pesquisa do Estado do Amazonas (FAPEAM 3137/2012).

As part of a review of gasteroid mycobiota from Rio Grande do Sul State, in southern Brazil, members of the Lysuraceae (Phallales) family were studied. Fresh and herbarium specimens were analyzed macro- and micromorphologically. Lysurus cruciatus, L. cruciatus var. nanus (new record from Brazil) and L. periphragmoides have been collected in the area. Their specific limits, distribution and ecological data are discussed. Macroscopic photographs and line drawings of the basidiospores are presented.As part of a review of gasteroid mycobiota from Rio Grande do Sul State, in southern Brazil, members of the Lysuraceae (Phallales) family were studied.

A survey of Geastrum species from arid lands in the La Rioja province (northwestern Argentina) recovered fourteen species previously unreported from the province: G. arenarium, G. campestre var. famatinum, G. corollinum, G. fimbriatum, G. floriforme, G. glaucescens, G. hieronymi, G. aff. lloydianum, G. pampeanum, G. pampeanum var. pallidum, G. parvistriatum, G. rufescens, G. saccatum, and G. schmidelii. Of these, new records are G. corollinum for Argentina, G. arenarium for South America, and G. parvistriatum for the Americas, and G. campestre var. famatinum is proposed as a new variety. Each taxon is described, and photographs of basidiomes and SEM micrographs illustrating spores are provided for selected taxa. Fil: Kuhar, José Francisco. Universidad de Buenos Aires.
