Abstract The hyphomycete sooty mould Capnofrasera
dendryphioides gen. et sp. nov. is based on specimens from New Zealand,
Chile, Venezuela, Brazil, Canada (B.C.), and USA (Hawaii). Hyphae are superficial,
cylindrical, and conidiophores are straight, robust, with irregularly alternate
or opposite, primary and secondary branches bearing terminal and lateral
mostly monoblastic conidiogenous cells, which may proliferate to produce
successive conidiogenous cells. Conidium scars of proliferated conidiogenous
cells may be torn and crescent-shaped or occasionally entire and circular.
Conidia are solitary, obclavate, brown, (1-)2- to 5(-12)-septate, and 14.5-48.5(-85)
x 5-9 µm. Apiosporium rehmii and Dendryphion fumosum
Woronichin & Budrina non (Corda) Fr. are discussed. Some tenuous evidence
suggests that Capnofrasera dendryphioides may be an anamorph of Antennulariellaceae.
The new genus is compared with Tomenticola, Paratomenticola,
Sporidesmiopsis, and Capnodendron.
