Who: John S. Harper (jsharper)

No specimen available

No idea what this is. On base of living hardwood. Soft, somewhat watery mass. Zoned interior. Turning grey after harvest and when cut. Will continue to observe and post further if anything develops. (Knife handle in third image is 4.5 inches long.)

On revisit to site 4 days after intial photos, the specimen had not grown much. The color had faded. The surface was very wet and was attacting flying insects. The darker colored structure at the center of the pits in the first photo was oozing a light brown foam. New photos are 47617 to 47619.

Did not find any pictures of various Inonotus on the internet that looked simialar to this.

Possibly this is a specimen of something that is being attacked by another fungus. The specimen taken home originally for a spore print (no luck) turned light grey, but this may be the bloom of another fuzzy fungus attacking it.


Note the pits on the surface. Cross sectioned piece at top of photo.

it’s some kind of beefsteak fungus or some polypore in the early stage of development …
