Conidiosporomyces ayresii (Berk.) Vánky
Sori in ovaries of Poaceae, scattered in the inflorescence, swollen, composed of an apically open sack-like membrane of host tissue and fungal origin, and a central semi-powdery mixture of spores, sterile cells and balls of conidia.
Spores relatively thick-walled, pigmented, moderately large.
Spore germination resulting in aseptate basidia bearing an apical cluster of elongate basidiospores.
Sterile cells pale, almost colourless, smooth or ornamented, often collapsed.
Conidia thin-walled, mostly Y-shaped, hyaline, arranged in loose balls.
Germination of basidiospores and conidia resulting in hyphae on which both blastic conidia and ballistospores are formed.
Host-parasite interaction by intercellular hyphae; interaction apparatus lacking.
Septal pore a dolipore traversed by 2 membranous plates; pore caps lacking.
This genus contains three species, one of which occurs in Australia. The presence of conida, together with spores, in the sori is unique among the smut fungi.
