In Huafo Mountain, Mouding, Yunnan Province, China, we found black protrusions on the leaf surface of plants. The collection which we identified as sp. nov., a new species of Acrocalymmaceae (Pleosporales) is characterised by dome-shaped ascomata, bitunicate asci with pedicel furcate and an ocular chamber and hyaline, obovoid to ellipsoid, 1-septate ascospores.
Morphologically, this species is typical with obovoid to ellipsoid, larger ascospores than other known species in . Phylogenetic analysis also showed that it represents a distinct clade, distant to any other species of . Therefore, we introduce it as , a new species of Acrocalymmaceae. This study is adding to the current situation where there are very few species and lack of teleomorph characteristics.
在中国云南省牟定县化佛山，我们在植物叶片表面发现了黑色突起物。我们鉴定该标本为新种，它属于顶孢腔菌科（格孢腔菌目），其特征为具圆顶形子囊果，具短柄且分叉和具眼腔的双层壁子囊，以及透明、倒卵形至椭圆形、具1个隔膜的子囊孢子。
在形态上，该物种具有典型的倒卵形至椭圆形，其孢子囊比该属其他已知物种的更大。系统发育分析还表明，它代表一个独特的分支，与该属的任何其他物种都有距离。因此，我们将其作为顶孢腔菌科的一个新物种进行介绍。这项研究增加了目前物种极少且缺乏有性型特征的情况。
