A new predatory hyphomycete capturing bdelloid rotifers in soil

open access: yes, 1983
Cephaliophora navicularis, a hyphomycete capable of capturing bdelloid rotifers by using specialized adhesive pegs, is described as new. Canoe-shaped conidia are produced synchronously on ovoid- to club-shaped ampullae that arise more or less directly ...
