Descriptions
Poria weraroensis G. Cunn. 1947
Accepted as 'Poria' weraroensis.
The holotype is badly eaten by insects, discoloured, and sterile. Only one other collection is known. This collection (PDD 50957), in agreement with Cunningham's description of P. weraroensis, has discrete and coalescing, circular, resupinate colonies, individually 5-15 mm across and 1 mm thick, coloured pale yellow with a white margin. Pores are large, 1-2 per mm, with the hymenium lining the floor of the shallow tubes and extending up the vertical tube walls. The dimitic hyphal system consists of clamped generative hyphae and hyaline to pale yellow, nondextrinoid skeletal hyphae. Spores are hyaline, ellipsoid, 3.5-5 x 2.5-3 µm.
Both the type and PDD 50957 appear to be young and not fully developed. The irregular hymenophore varying from almost smooth through tuberculate to dentate or poroid in the centre of the small fruit-bodies strongly resembles species of Schizopora. However, the sterile elements typical of this genus are lacking in the fertile collection (PDD 50957), although the spores and the hyphal system come very close to that of S. paradoxa (Schrad.: Fr.) Donk, a widespread and variable species. The protruding skeletal hyphae in the dissepiments of S. paradoxa have a characteristic scattered, rather coarse encrustation. Some hyphae in P. weraroensis are encrusted, but they differ in appearance from those seen in Schizopora. The hymenium in young specimens of Schizopora often covers both the pore base and the side walls, underlining the relationship of this genus to many smooth and grandinioid species in the Corticiaceae.
The dimitic hyphal system and fertile pore bases suggest that P. weraroensis might belong in Theleporus Fr. but the species lacks the dendrohyphidia and the more regular pore surface seen in even young and small fruit-bodies of Theleporus.
More collections are needed before a proper evaluation of this species can be made.
