Notes – Emarcea castanopsidicola was introduced from dead leaves of Castanopsis diversifolia in northern Thailand (Duong et al. 2004). The genus is characterized by immersed, globose to subglobose, coriaceous, solitary ascomata, immersed under a blackened clypeus and hyaline apiospore with mucilage at the ends and idriella-like asexual morphs. Emarcea differs from Induratia by its long fusiform ascospores, obclavate apical cells and similar by its apiospores without germ slits (Li et al. 2009, Daranagama et al. 2018). The ITS, LSU, rpb2 and tub2 multigene phylogeny revealed that Emarcea is basal to Induratia with high statistical support.
