Phialophora is a little-differentiated genus of more or less pigmented, phi
alidic hyphomycetes. With the addition of numerous species, it has become h
ighly polyphyletic, comprising anamorphs of discomycetes, pyrenomycetes and
loculoascomycetes. The core of the genus consists of anamorphs of Capronia
in the Herpotrichiellaceae, Chaetothyriales. Some taxa have already been s
egregated from Phialophora into genera such as Lecythophora (Coniochaetacea
e) and Phaeoacremonium (Magnaporthaceae?). Ascomycete orders in which phial
ophora-like fungi have been placed are reviewed, and some further segregati
on is proposed. For the common anamorphs of the discomycete family Dermatea
ceae, the old generic name Cadophora is available and should be used for Ph
. fastigiata and related taxa (one new combination). For anamorphs of Gaeum
annomyces and Magnaporthe (Magnaporthaceae), a new genus, Harpophora, is pr
oposed with four new combinations. Criteria that allow a correlation with t
he suggested broad-scale subdivision are outlined.
