Fruiting body: diam 1cm ruffled, beige

Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
The reaction to scratching in S. rugosum is variable, can be slow, and depends how fresh or hydrated it is. Quite often I have to scratch it two or three times before it gives the expected response.
The main Stereum that does not scratch red is S. hirsutum, but that has a brighter lower surface (hymenium) and in the situation depicted it would have much better formed brackets.
I still regard the photograph as most probably S. rugosum.
