对狭义干蘑属(Xerula s.str.)的范围进行了重新界定,该属仅包括模式种干蘑(X.pudens)及其周围的几个种.属的特征是担子果金钱菌状,有假根;菌盖及菌柄表面干燥,被有黄色至褐色直立、披针形的刚毛;菌褶边缘无不育带;子实层有近梭形的小担子.这些特征可以将干蘑属的物种从干蘑属-小奥德蘑属复合群中分开.现知干蘑属包含六种,本文提供了这些种的检索表,并对各种进行了描述、图示或讨论.其中,硬毛于蘑(X.strigosa)是一新种,它与干蘑(X.pudens)和中华干蘑(X.sinopudens)相似,但与十蘑不同在于其担孢子较长,锁状联合稀少,侧生囊状体顶端壁薄;与中华十蘑的区别在于其侧生囊状体壁厚,顶端有头状至近头状膨大并覆盖有结晶,担孢子宽椭圆形至椭圆形.中华干蘑和小刺干蘑(X.setulosa)分别为我国和哥斯达黎加的新记录种.干蘑属虽然广布北半球,但未见东亚-美洲或欧亚广布的物种分布类型.

The genus Xerula s.str.has been revised andis circumscribed as an assemblage oflaxa strictly around the type of the genus,X.pudens.The collybioid basidioma with a pseudorhiza;the dry surfaces of the pileus and the stipe covered with erect,lanceolate,yellow to brown,thick-walled setae;the subacerose basidioles in the hymeniura and the fertile lamellar edge delimit Xerula species from other taxa of the Xerula-Oudemansiella complex.Currently,Xenda contains six species.A keytothe species,descriptions,illrstrations ordiscussions of the taxa are provided.Xerula strigosa represents a new species resembling X.pudem and X.sinopudem.Xerula sinopudens and X.setulosa are records new to China and Costa Rica respectiveiy.Although Xerula is widely distributed in the Northern Hemisphere,no species of it has an East Asian-American or European-Asian distribution pattern.
