Farysporium endotrichum (Berk.) Vánky on Gahnia sp.
Sori surrounding the pedicels, peduncles and main axes of the inflorescence of Gahnia (Cyperaceae), forming black agglutinated to granular or granular-powdery masses of spore balls and spores mixed with fascicles of sterile hyphae (elaters); columella absent.
Spores in loose balls, pigmented. Spores and fascicles of sterile hyphae differentiating from a fungal stroma on the surface of the host tissues.
Sterile cells (excluding elaters) absent between or within the spore balls. Spore germination resulting in either septate basidia or long filaments.
Host-parasite interaction by intracellular hyphae coated by an electron-opaque matrix.
Septa poreless at maturity.
The monotypic Farysporium is similar to Farysia in that both have fascicles of sterile hyphae (elaters) between the spore masses. However, Farysia has sori that are covered by a thick peridium when young in the seeds of Carex spp. Moreover, the spores of Farysia are solitary, never forming spore balls.
