Type species – Endocalyx thwaitesii Berk. & Broome
Notes – Petch (1908) emended the genus, and considered that E. thwaitesii and E. psilostoma were identical. Okada & Tubaki (1984) described E. melanoxanthus var. grossus and E. melanoxanthus var. melanoxanthus. The genus is characterized by funnel-shaped synnemata or sporodochia, branched conidiophores and dark brown conidia with a germ slit (Seifert et al. 2011).
