During the summer and autumn of 2020, 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.

Abstract [فارسی]

در تابستان و پاییز سال 1399، برای شناسایی برخی آرایه‌های قارچی مرتبط با گیاهان، از باغ‌ها و جنگل‌های استان‌های البرز، گلستان، گیلان و مازندران بازدید به عمل آمد و از گیاهان مو (Vitis vinifera)، سرو زربین (Cupressus sempervirens)، آلو بخارا (Prunus spinosa) و علف قناری (Phalaris minor) دارای علایم بیماری، نمونه‌برداری انجام شد. پس از جداسازی و خالص‌سازی، شناسایی ریخت‌شناختی و مولکولی آرایه‌ها با استفاده از توالی‌یابی نواحی ژنومی ITS rDNA صورت گرفت. براساس تلفیق داده‌های حاصل از ریخت‌شناسی و مولکولی، در تحقیق حاضر، چهار گونه متعلق به چهار جنس مختلف از تیره Chaetomiaceae (رده Sordariomycetes، راسته Sordariales) شامل گونه­های Ovatospora brasiliensis از مو، Dichotomopilus erectus از سرو زربین و Staphylotrichum longicolle از علف قناری و همچنین تیره Didymosphaeriaceae (رده Dothideomycetes، راسته Pleosporales) شامل گونه Pseudopithomyces chartarum از آلو بخارا، شناسایی و معرفی می‌شوند که تمام جنس‌ها و گونه‌های به دست آمده برای فونگای ایران جدید هستند. همچنین درختان مو، سرو زربین، آلو بخارا و علف قناری به عنوان میزبان‌های جدید برای این آرایه‌ها در دنیا گزارش می‌شوند.
