When I photographed this mushroom, I was almost certain it to be Inonotus hispidus or something along those lines. But when I examined the specimen, it appeared to be I.resinosum. I’m just surprised at triangled shape of the fruit body – I.resinosum is usually flatter, with a descending patch on the trunk as well as the shelf itself.
