Discoxylaria is shown to be a distinctive genus of family Xylariaceae
(Ascomycetes, Pyrenomycetes, Sphaeriales). Its Hypocreodendron anamorp
h is hyphomycetous rather than coelomycetous as originally reported. C
onidia are produced holoblastically; the conidiogenous locus prolifera
tes by a variation of the percurrent mode.
