SUMMARY
Fifteen species and one n. comb, of Merulius and Phlebia proposed by Lloyd are redescribed and 8 type specimens illustrated. The following names are placed in synonymy: M. aurantius, M. conchoides, M. ochraceus, and M. succineus with M. corium (Fries) Fries; Phlebia castanea and P. merulioides with M. rufus Fries; M. gelatinosus with Serpula himantioides (Fries) Bond ex Parm. and M. Candidus with Porogramme calcicolor (Sacc. & Syd.) Lowe. Merulius carbonarius, M. consimilis, M. crassus and M. fuscus are neither typically Serpula nor Merulius but are retained temporarily in the latter. The combination M. corium var. pallensis rejected because M. pallens Berk, is a distinct species from M. corium. Merulius debriscolus is discarded because the type lacks any sign of a fungus. Merulius erectus is perhaps a member of Aphelaria Corner. Merulius castaneus is Cystidiophorus castanea (Lloyd) Imazeki.
