Abstract

The new genus and species Bullatosporium taxicola are described from dead wood of Taxus baccata in western Norway. Despite some morphological resemblance with Hysteriaceae, including low ascomata with a thick carbonized peridium and mainly five-septate ascospores, multigene analysis of the five molecular markers SSU, ITS, LSU, TEF1-α and RPB2 revealed an affinity to Mytilinidiaceae. The new species formed a strongly supported sister clade to the remaining strains of Mytilinidiaceae. Dichotomous keys to genera of Mytilinidiaceae and to hysterioid species with phragmospores in Fennoscandia are provided to aid identification. Citation: Andreasen M, Jordal JB, Nordén B (2024).

挪威西部多孢子菌科（多孢子菌科，多孢子菌科）一新属新种。

本文报道了挪威西部红豆杉（taxicola）枯木新属新种。尽管在形态上与Hysteriaceae有一定的相似性，包括低子囊、厚的炭化包皮和主要的五裂子囊孢子，但对SSU、ITS、LSU、TEF1-α和RPB2等5个分子标记的多基因分析显示其与mytillinidiaceae有亲缘关系。新种形成了一个强有力的支持的姐妹分支，以mytillinidiaceae的剩余菌株。为帮助鉴定，提供了芬诺scandia中Mytilinidiaceae属和带芦苇孢子的hysterioid种的二分类键。引用本文：Andreasen M， Jordal JB, nordsamn B（2024）。挪威西部多孢子菌科（多孢子菌科，多孢子菌科）一新属新种。真菌分类学与进化14:197-207。doi: 10.3114 / fuse.2024.14.13。
