多年卧孔菌属五个中国新记录种

摘要

Five species in the genus Perenniporia,P.africana,P.decurrata,P.ellipsospora,P.inflexibilis and P.xantha are newly recorded from China.Perenniporia africana was found in Anhui Province,and it is characterized by its buff-colored to ochraceous pore surface and unbranched skeletal hyphal; P.decurrata was collected from Yurman Province,and it is distinguished by its pileate basidiocarps,tiny pores (7-9 per mm) and smaller,truncate basidiospores; P.ellipsospora was found in Yunnan Province,and it is characterized by its resupinate basidiocarps with round to angular pores,and not truncate basidiospores; P.inflexibilis was found in Fujian Province,and it is characterized by its grey to pale brown pore surface with small pores (6-8 per mm),and hyaline to slightly yellowish basidiospores; P.xantha was collected from Hainan Province,and it is characterized by its buff to bright yellow pore surface with small pores (6-8 per mm),and its tubes becoming dark brown in KOH.Illustrated descriptions of these five species are given based on the Chinese materials.%报道了多年卧孔菌属Perenniporia5个中国新记录种.非洲多年卧孔菌Perenniporia africana采自安徽省,孔口表面浅黄色至赭色,且骨架菌丝不分枝；下延多年卧孔菌P.decurrata采自云南省,担子果盖形,具较小孔口和担孢子；椭圆孢多年卧孔菌P.ellipsospora采自云南省,担子果平伏,孔口圆形至多角形,担孢子不平截；硬多年卧孔菌P.inflexibilis采自福建省,担子果盖形,孔口表面灰白至浅褐色,担孢子无色至浅黄色；黄多年卧孔菌P.xantha采自海南省,孔口较小,表面呈黄色,且在KOH试剂中呈深褐色.根据采集的标本材料提供了它们的详细描述和显微结构图.
