Introduction of new taxa of Dothideomycetes and Sordariomycetes associated with trees for funga of Iran

In order to identify fungi associated with canker and leaf spot symptoms of plants, the gardens and forests of Alborz and Guilan provinces were surveyed and infected plant samples were collected from kiwifruit (Actinidia deliciosa), hawthorn (Crataegus monogyna), grapevine (Vitis vinifera) and linden (Tilia cordata) trees, during the summer and autumn of 2020. After isolation and purification of fungal strains, morphological and molecular identification were performed using the sequences of ITS rDNA region. Based on combined data, finally, five fungal species belonging to the class Dothideomycetes including Neosetophoma guiyangensis from hawthorn and Scolecobasidium cordanae from linden and the class Sordariomycetes including Corynascus sepedonium from grapevine, Harzia palmara from kiwifruit and Sordaria arctica from hawthorn were identified and reported. In the present study, all identified taxa except C. sepedonium, are new for the funga of Iran. Also, kiwifruit, hawthorn, grapevine and linden trees are reported as new hosts (matrix nova) for respective fungal taxa in the world.
