Abstract
Conidia of M. coniospora Drechsler, an endozoic nematophagous fungus, were examined by EM at various stages of infection. The conidia are almost conical in shape and develop a knob-like structure at the apical end. Ultrathin sections show that the knob is always covered with a mucous layer, which is composed of a number of radiating fibrils. Attachment to the nematode''s integument is by means of this fibrillose layer. The germ tube from the bud grows between the conidium and nematode and forms a tiny infection bladder in the integument.
