While surveying the mycobiomes of dead woody litter in Yunnan Province, China, numerous isolates with affinity to Pleosporales (Dothideomycetes, Ascomycota) were recovered. The present work characterizes two species associated with dead woody twigs found in terrestrial habitats in the Kunming area of Yunnan. The novel taxa were recognized based on a polyphasic approach, including morphological examination and multiple gene phylogenetic analyses (non-translated loci and protein-coding regions). Neokalmusia jonahhulmei sp. nov. is introduced in Didymosphaeriaceae (Pleosporales) as a woody-based saprobic ascomycete that possesses multiloculate ascostromata immersed under a black clypeus-like structure, and three-septate, brown, fusiform, guttulate ascospores. Thyridaria jonahhulmei (Thyridariaceae) is introduced with teleomorphic and anamorphic (coelomycetous) characteristics. The teleomorph has the following characteristics: globose to subglobose ascomata with an ostiolum, a pruinose layer of yellow to reddish- or orange-brown material appearing around the top of the ostiolar necks, and brown, ellipsoid to fusoid, two-to-three-septate, euseptate, rough-walled ascospores; the anamorph features pycnidial conidiomata, phialidic, ampulliform to doliiform, conidiogenous cells, and brown, guttulate, ellipsoidal, aseptate conidia.
在中国云南省对枯木凋落物的真菌群落进行调查时，分离出了许多与格孢腔菌目（座囊菌纲，子囊菌门）相关的菌株。本研究描述了在云南省昆明市地区陆生栖息地发现的与枯木小枝相关的两个物种。这些新分类单元是基于多相分类法确定的，包括形态学检查和多基因系统发育分析（非翻译位点和蛋白质编码区）。新种约拿胡尔梅新拟卡尔穆菌（Neokalmusia jonahhulmei sp. nov.）被归入座囊菌科（格孢腔菌目），是一种以木材为基质的腐生子囊菌，具有浸没在黑色盾状结构下的多腔子囊座，以及具三隔膜、棕色、梭形、具油滴的子囊孢子。约拿胡尔梅梯盘菌（Thyridaria jonahhulmei，梯盘菌科）被描述为具有有性型和无性型（腔孢纲）特征。有性型具有以下特征：球形至近球形的子囊果，有孔口，在孔口颈部顶端周围出现一层黄色至红棕色或橙棕色的粉状物质，以及棕色、椭圆形至梭形、具二至三隔膜、真隔膜、壁粗糙的子囊孢子；无性型具有分生孢子器，瓶梗状、壶形至桶形的产孢细胞，以及棕色具油滴、椭圆形、无隔膜的分生孢子。
