Case for S. complicatum

I’m gonna make a case for S. complicatum according to the bracket being zonate and pliant in maturity, and having some bright orange on the underside (near the base, anyways).

S. complicatum in general is characterized by “a wavy margin…a paler whitish margin; silky-hairy, concentric zones and furrows, smooth and shiny near margin” according to Roger’s Mushrooms and Lincoff (1981). This description overall matches the specimen.

Conversely, S. striatum appears to be less frequently zoned. Arora (1986) and rogersmushrooms both say S. striatum is “sometimes concentrically zoned” and the pictures from Messiah college here show it without prominent zones at all: http://www.messiah.edu/...
S. striatum is more “shell-like, leathery, silvery” (Lincoff) and is only pliant when fresh while this one here is colorfully zoned and quite pliant even in maturity.

In addition, the underside near the base is bright yellow-orange which agrees more with Arora and Lincoff’s description of S. complicatum than S. striatum.

I wouldn’t consider S. ostrea which tends to be larger and not reflexed. The name complicatum means “folded back on itself.” See Tom Volk’s FOTM page on S. ostrea, which conveniently has a picture of S. complicatum to compare: http://botit.botany.wisc.edu/toms_fungi/nov2000.html

Stereum striatum? S. complicatum tends to be more resupinate, not so reflexed and not so zonate either.

The exposure seems to show a silkiness (a highly reflective spot) and the striations are quite evident.
