Trichocintractia M. Piepenbr.
Trichocintractia utriculicola (Henn.) M. Piepenbr. on Rhynchospora gigantea Link
Sori develop in scattered spikelets of Cyperaceae transforming
the top of the rachillae into globose soral bases just before floral differentiation.
Spore mass dusty, contained within a sac, formed by a persistent
thick peridium of globose fungal cells. From the soral base, groups of
long smooth sterile cells with thick walls radiate into the spore mass.
Between sterile cells, globose groups of teliospores develop.
Spores globose, simple, pigmented, covered by an ornamentation
that is loosely connected to the exosporium.
Sterile cells developing in groups from the base of sori, long, smooth, with thick walls.
Spore germination resulting in phragmobasidia producing basidiospores
Host-parasite interaction by intracellular hyphae, coated by an
Septa poreless at maturity.
Trichocintractia is a monotypic cosmopolitan genus.
