During the summer and autumn of ۲۰۲۰, in order to identification of some fungal taxa associated with plants, gardens, weeds and forests of Alborz, Gorgan, Guilan and Mazandaran provinces (north of Iran) were surveyed and infected plant samples were collected from grapevine (Vitis vinifera), Mediterranean cypress (Cupressus sempervirens), blackthorn (Prunus spinosa), and little seed canary grass (Phalaris minor) plants. After isolation and purification of fungal strains, morphological and molecular investigations were performed using the sequences of the ITS rDNA genomic regions. Based on combined morphology and molecular data, four fungal species belonging to four different genera of Chaetomiaceae (Sordariales, Sordariomycetes) including Ovatospora brasiliensis from grapevine tree, Dichotomopilus erectus from Mediterranean cypress and Staphylotrichum longicolle from little seed canary grass, and Didymosphaeriaceae (Pleosporales, Dothideomycetes) including Pseudopithomyces chartarum from blackthorn are identified and introduced here for the first time. In the present study, all identified genera and species are new for the funga of Iran. In addition, little seed canary grass, grapevine tree, blackthorn, and Mediterranean cypress are reported as new hosts (matrix nova) for these recovered fungal taxa in the world.
