R. Kirschner et F. Oberwinkler, Phialocephala trigonospora, a new hyphomycete species associated with conifericolous bark beetles, SYDOWIA, 50(2), 1998, pp. 205-212
A new species of the hyphomycete genus Phialocephala was isolated from coni
fericolous bark beetles and their galleries in Germany. The species differs
from all known species of this genus by its conidia which have a triangula
r shape. The development of the conidia was investigated with scanning and
transmission electron microscopy.
