Nine Pezizomycotina strains were isolated from rotten dead branches and leaves collected from Guizhou Province. To obtain their accurate taxonomic placement, we provided the morphological characteristics of conidiophore cells and conidia. Phylogenetic relationships, based on ITS, , SSU, LSU and gene sequences, confirmed our strains represented three novel species, , and . produced falcate conidia and generated fusiform conidia, while possessed cylindrical conidia. The phylogenetic results also supported them as novel taxa. All the new species in the present study were found as saprophytic on forest litter with high rainfall, which suggest they may have a certain effect on nutrient decomposition and redistribution in forest ecosystems. Thus, it opened a way for further research on related ecological roles and their application production.
从贵州省采集的腐烂枯枝落叶中分离出9株粪壳菌纲菌株。为了准确确定它们的分类地位,我们给出了分生孢子梗细胞和分生孢子的形态特征。基于ITS、SSU、LSU和基因序列的系统发育关系证实,我们的菌株代表了3个新物种,即、和。产生镰形分生孢子,产生梭形分生孢子,而具有圆柱形分生孢子。系统发育结果也支持它们为新分类群。本研究中的所有新物种均为高降雨地区森林凋落物上的腐生菌,这表明它们可能对森林生态系统中的养分分解和再分配有一定作用。因此,这为进一步研究相关生态作用及其应用生产开辟了道路。
