Sarcodontia spumea (Spongipellis spumeus) was confirmed by Hans Adema, hence the change from ‘could be’ to ’I’d call it that’.

Yes, I have a microscope

But this specimens were found a couple of months ago. They aren’t around anymore. The pore surface was indeed more regular as opposed to laccerate/dentate and irregular. I did the scent and taste test myself and found some records in the literature I’ve used. All authors mentioned no scent to slightly anisy and a mild flavour.
(I have to get all my scope stuff together again, though (slides, chemicals etc). It has been over 10 years ago that I’ve used it…)

I too

am a proud owner of Ryvarden’s 2013 polypore bible. I see he lists it as a Spongipellis, and remarks that it can be confused with S. delectans, which has “laccerate and dentate dissepiments and often somewhat irregular pores, while those of S. spumeus are regular and the pore surface is smooth.”

Yours certainly look more “spumeoid” in that regard, but a closer look is always helpful. He makes no mention of taste or odor, so I assume you took that from other sources.

Do you have access to a microscope?

Thanks for the welcome, it is much appreciated :D
I have posted this spotting on a couple of facebook fungi id groups (two groups that I host, and one called ‘All things Polypore’). At one of my own groups, a colleague of mine from the Dutch Mycological Society (Jan Knuiman) suggested this species. He had taken the description and photographs and compared it to the latest edition of Poroid fungi of Europe (Ryvarden et al., 2013). This species was mentioned to grow on dead and living Fagus aswell. I’ve been digging into some books myself after that: Pilze der Schweiz Band 2 (Breitenbach&Kränzlin, 1986), Paddestoelen van West-Europa (Phillips, 1993), Der grosse Kosmos Pilzfuhrer (Laux, 2001) en De grote paddenstoelengids voor onderweg (Gerhardt, 2013). Laux only describes the species in the notes, the other books have a proper description and photographs. Everything seems to fit: size, the mild taste, the bilayered trama, the fairly large pores and especially the moistiness, which was specifically mentioned in Gerhardt. And as I said in the Notes of my description, the top was quite spongy, with which I mean it was more or less ‘hairy’ almost like Aurantiporus fissilis. Which is said to be the doppelgänger in many of the books, but I know that species quite well, as a friend of mine has it growing on one of is Apple trees.

and welcome to Mushroom Observer. All members are welcome, of course, but for me, those with lots of ID experience are, let’s say, especially welcome :)

Can I ask how you arrived at this name, and if there are any good field characters for recognizing Sarcodontia?
