Type description

van Geel 1978: Fruit-bodies globose, black, with a coarsely verrucose wall, 150-300 μm in diameter; on a subiculum (hyphal mat under the fruit-body), beset with black ca. 8 μm wide setae (mostly broken off in the fossil material). Most of the fruit-bodies still contained ascospores, and sometimes the ascospores had germinated before fossilisation, germination taking place from one or both of the terminal cells of the ascospores. Mycelium 5-8 μm wide, thick-walled, septate, branched and forming a dense network, bearing two-celled capitate hyphopodia (the anchoring and parasitic organs of the hyphae), about 14-17 x 10-12 μm, with a pore of about 1.5 μm in diameter (probably the place where the - not observed - haustorium, penetrating the host cell, was connected with the hyphopodium. Ascospores 41-55 x 14-18 μm, three-septate, inequilateral (one side almost straight), slightly constricted at the septa. Septa thickened around the ca. 1.5 μm wide pore.
