Notes on some endophytic fungi isolated from Quercus brantii in Dena, Kohgiluyeh and Boyer-Ahmad provincem, Iran

In this study, we report some endophytic fungi isolated from twigs of Quercus brantii in Dena region of Kohgiluyeh and Boyer-Ahmad province. The twigs were sampled from trees which had basidiocarps of the invasive basidiomycetous polypore fungus Inonotus krawtzewii on their trunk. Altogether, ca. 40 pure isolates were obtained. The ITS sequences were obtained for 16 isolates, and their phylogenetic relationships were analysed. Altogether, 13 taxa were identified based on morphological and molecular data. The identified species include: Alternaria alternata, A. cf. arborescens, Kalmusia variispora, Purpureocillium lilacinum, Lentinus tigrinus, and Lopadostoma quercicola. A number of isolates could be identified at generic level (Coniochaeta, Cytospora, Diatrype, Pyronema, Ulocladium), while the rest of isolates were identified only at family (Phaeosphaeriaceae), and order (Pleosporales) levels. The identified isolates belonged to ascomycetes, except one basidiomycetous fungus L. tigrinus. Brief descriptions and microscopic illustrations are given for some isolates.
