Recognized by sight: No records of L. boryana have been confirmed from the US in some 25 years of focused efforts on the genus and its specific distribution.
Used references: Mata et al., “The Genus Lentinula in the Americas.” Mycologia 93.6 (2001): 1102-1112. (http://0-www.jstor.org.catalog.multcolib.org/stable/3761671) + personal correspondence with Dr. Mata.
Based on microscopic features: “Lentinula raphanica can be distinguished from L. boryana by the shape of the cheilocystidia and basidiospore dimensions. Cheilocystidia of L. raphanica are clavate and frequently knobbed or diverticulate at the apex and somewhat smaller in size. Spores of L. raphanica have a narrower shape, more subcylindrical than oblong, judged by its higher mean ratio of Q = 2.16. Caulocystidia are also different, more clavate and knobbed in L. raphanica than in L. boryana.” (Mata et al. 2001)

I’m curious

Something about it reminds of a Lentinellus, also Rhodocollybia, but I can’t find a species that actually looks like this. Hasn’t anyone else got an idea?

Any particular taste, smell, spore colour?
