More records of xylariaceous fungi from North of Iran

This study was carried out to contribute to the knowledge of biodiversity of xylariaceous fungi from north of iran. plant materials with fruiting bodies of xylariaceous fungi were collected and examined. eight species viz. annulohypoxylon nitens, biscogniauxia anceps, b. capnodes var. rumpens, b. mediterranea, b. plana, hypoxylon flavoargillaceum, jumillera cinerea, and nemania illita were identified. all these except b. mediterranea are new to the iranian mycobiota. a dichotomous identification key for all the xylariaceous fungi examined by the authors from north of iran is presented.
