Gloeophyllum sepiarium is called “Rusty Gilled Polypore”. Don’t see much rusty gills here. Also, gills are said to be “close, ochre to yellow-brown or rusty-brown becoming brownish in old age, often fused to form elongated pores or sometimes the underside of cap entirely poroid or even toothlike.” Doesn’t seem to match this observation, Alan.

In Arora’s key, doesn’t this come out more as 13b: “Found on other conifers; cap often poorly developed (see Coriolellus heteromorphs under Poria corticola, p. 603)”?
