Acrocalymmachuxiongense sp. nov., a new species of Acrocalymmaceae (Pleosporales) on leaves of Quercus.

ABSTRACT:

Background

In Huafo Mountain, Mouding, Yunnan Province, China, we found black protrusions on the leaf surface of Quercus plants. The collection which we identified as Acrocalymmachuxiongense 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.

New information

Morphologically, this species is typical with obovoid to ellipsoid, larger ascospores than other known species in Acrocalymma. Phylogenetic analysis also showed that it represents a distinct clade, distant to any other species of Acrocalymma. Therefore, we introduce it as Acrocalymmachuxiongense, a new species of Acrocalymmac
