Notes: Pilát (1940) described Eichleriella chinensis from China without data on basidia and basidiospores. Later, Boidin et al. (1979) described Stereum peculiare based on specimens from U.S. S. R. and India. Malysheva & Spirin (2017) excluded Eichleriella chinensis from the genus but did not suggest any alternative classification. We re-studied types and authentic materials ( Fig. 10A–D View Fig ) of the two species and found them to be conspecific. The species is common in northern China, but specimens are usually sterile. See Pilát (1940) and Boidin et al. (1979) for descriptions and illustrations.
