Notes – Rhopalostroma species are characterized by pedicellate, melanized stromata with often abruptly expanded convex heads. The globose to subglobose stromatal morphology of Rhopalostroma is close to Phylacia. Rhopalostroma possesses a single layer of ascomata in the stroma, asci with apical ring and ascospores with a germ slit, which differs from Phylacia with multilayers and compact ascomata in the stroma, lack of ascal apical ring and lack of germ slit in the ascospores. Rhopalostroma species are restricted to subtropical Africa and South Asia. Based on morphological affinities with Thamnomyces and Phylacia, phylogenetic analyses and secondary metabolite profiles, the genus is accepted in Hypoxylaceae (Hawksworth 1977, Stadler et al. 2010, Daranagama et al. 2014, 2018, Wendt et al. 2018). 

Type species: Rhopalostroma indicum D. Hawksw. & Muthappa, in Hawksworth, Kew Bull. 31(3): 426 (1977) 

Other accepted species: Species Fungorum – search Rhopalostroma.
