Wei Y.L. & Qin W.M. (2010). Two new species of Postia from China.

Sydowia 62(1): 165.–170

Two new species of Postia from China, P. obliqua and P. zebra, are described and illustrated. Postia obliqua was collected on Larix from Xizang Autonomous Region. The most striking character of this species is its resupinate, large basidiomata with a size of up to 100 cm × 50 cm. Its tubes are oblique and its subiculum is almost lacking. Postia zebra was collected from a rotten stump of Abies sp. in Changbaishan Nature Reserve, Jilin Province. It resembles P. balsamea in spore size but differs from the latter by its zonate pileus and the lack of cystidia.
