گزارشي از قارچ‌هاي مولد زنگ در منطقه البرز مركزي

RUST MYCOBIOTA OF CENTRAL ALBORZ, NORTHERN IRAN

سيزده آرايه زنگ از سه جنس Phragmidium، Puccinia و Uromyces از ناحيه البرز مركزي گزارش مي‌گردند. گونه‌هاي Phragmidium asiae-mediae، Ph. tranzschelianum به ترتيب روي Geum kokanicum و Rosa iberica؛ Puccinia hieracii var. piloselloidarum روي Hieracium woronowianum؛ Uromyce geranii روي Geranium spp. و Uromyces eurotiae روي Krascheninnikovia ceratoides به عنوان آرايه‌هاي جديد براي ميكوبيوتاي ايران معرفي مي‌شوند. مرحله اوردينيومي Ph. asiae-mediae و اوردينيوسپورهاي Ur. bupleuri براي اولين بار در اين نوشتار شرح داده مي‌شوند. گونه كمياب Pu. monopora روي Asperula glomerata پس از گذشت بيش از يكصد سال، براي دومين بار در ايران گزارش مي‌شود. گونه‌هاي جديد زنگ براي ناحيه البرز مركزي و هم‌چنين ميزبانان جديدي براي زنگ‌هاي شناسايي شده معرفي مي‌شوند.

Central Alborz region has been explored since 18th century by different botanists and mycologists. The results of all these expeditions are several publications about flora and mycobiota of the region. Literature review of publications about Central Alborz showed no special publication about rust mycobiota of this region. The lack of information about rust mycobiota of Central Alborz was the main reason for doing this research. During our study, several rusted specimens were collected and identified, thirteen of which belonged to genera Phragmidium, Puccinia and Uromyces reported here. Among the studied taxa, Phragmidium asiae-mediae, Ph. tranzschelianum on Geum kokanicum and Rosa iberica, respectively; Puccinia hieracii var. piloselloidarum on Hieracium woronowianum, Uromyces geranii on Geranium spp. and Ur. eurotiae on Krascheninnikovia ceratoides are newly reported from Iran. Uredinial state of Ph. asiae-mediae and Ur. bupleuri are reported here for the first time. Puccinia monopora is reported on Asperula glomerata for the second time since 1901. New rust taxa for Central Alborz and new hosts for Iranian rust mycobiota are also reported.
