Apparently, based on other MO observations of Abortiporus biennis

it can stain many different colors, although the predominant color seems to be white or whitish. In obs. 111248, 111078, 111059, 81145, 80916, 79846, 81207, 77407, 74342, 67550, 67414 it has many other colors. Or do these obs. need revision?

Regarding zaca’s observation 81330: it looks to my eye to be young. I see no “faraway” differences. Perhaps zaca can give more specifics regarding “faraway?”

The preponderance of observations on MO show mostly white sporocarps, but with distinct reddish areas (bruising?) and/or cinnamon areas.

faraway to what I observed before as Abortiporus biennis (see, for instance, observation 81330).

I should had given some.
These specimens grew directly from wood and the photos where taken at their place of insertion. To the cut one realizes that it has the consistency of cork. I attach photos of a cross section, that also include the reaction to KOH either on the cut surface as well as in the exterior.
Thanks, Tuberale, for your interest.

Not enough data to support any identification, zaca.

Was this found on the wood as the photos suggest? Or was it placed on the wood for convenience? Was it found above ground (epigeous) or could an animal have found it and placed in on the wood (hypogeous)? There does not seem to be a point of attachment to wood in the photos.


If epigeous, Polyporaceae possible.

If not epigeous, similar to Hydnotrya.

A cross-section of the sporocarp would also be helpful.
