Scanning electron and interference contrast microscopy of conidiogenes
is in Phialocephala humicola revealed a replacement wall building deve
lopment type with a peculiar disposition of conidia at the apex of the
conidiogenous cell. A pattern of conidiogenesis, similar to the one d
escribed for Chloridium virescens var. chlamydosporum, is proposed. A
key to the members of Sporendocladia and Phialocephala is given.
