Abstract

Species of Botryosphaeriaceae are important pathogens and endophytes associated with woody plants. Botryosphaeria and Neofusicoccum are two well known genera of the family. In this study 125 isolates morphologically resembling members of this family were collected from about 20 different fruit and forest trees in Iran. Based on morphology, MSP-PCR profile and DNA sequence data (ITS and tef1-a), four species were identified. Of these, Botryosphaeria dothidea, Neofusicoccum mediterraneum and N. parvum are known while Botryosphaeria scharifii is described here as new. N. mediterraneum is a new record for Iran and is reported here for the first time on mango trees. High diversity within Iranian population of N. parvum suggests the need to revise and reassess the morphological species description of N. parvum and closely related species.

Subjects
taxonomy, Botryosphaeriaceae, Dothiorella, Spencermartinsia, ITS, phylogeny, systematics
Abstract

Dothiorella and Spencermartinsia are two botryosphaeriaceous genera with dark 2-celled conidia and found in parasitic, saprophytic or endophytic association with various woody host plants. Based on ITS and EF1-α sequence data and morphology, eight new species are described from Iran, New Zealand, Portugal and Spain. Of these, five species are placed in Dothiorella, namely D. iranica, D. parva, D. prunicola, D. sempervirentis and D. striata, and three species belong to Spencermartinsia named as S. citricola, S. mangiferae and S. plurivora. An identification key to the species of each genus is provided.

Abstract

Four new species of Lasiodiplodia; L. citricola, L. gilanensis, L. hormozganensis and L. iraniensis from various tree species in Iran are described and illustrated. The ITS and partial translation elongation factor-1α sequence data were analysed to investigate their phylogenetic relationships with other closely related species and genera. The four new species formed well-supported clades within Lasiodiplodia and were morphologically distinct from all other known species.

6. Barriopsis iraniana and Phaeobotryon cupressi: two new species of the Botryosphaeriaceae from trees in Iran

Abstract

Species in the Botryosphaeriaceae are well known as pathogens and saprobes of woody hosts, but little is known about the species that occur in Iran. In a recent survey of this family in Iran two fungi with diplodia-like anamorphs were isolated from various tree hosts. These two fungi were fully characterised in terms of morphology of the anamorphs in culture, and sequences of the ITS1/ITS2 regions of the ribosomal DNA operon and partial sequences of the translation elongation factor 1-α. Phylogenetic analyses placed them within a clade consisting of Barriopsis and Phaeobotryon species, but they were clearly distinct from known species in these genera. Therefore, they are described here as two new species, namely Barriopsis iraniana on Citrus, Mangifera and Olea, and Phaeobotryon cupressi on Cupressus sempervirens.
