Recognized by sight: Kuo " Apparently Syzygospora mycetophila is not, strictly speaking, the stuff that we see on the mushroom; the jelly-like growths are composed of tissue from the mushroom itself and are induced by the parasite, which uses them for its own ends" Looks like what might be happening here.

what happened to it? I remember seeing observations entitled Fungus species and Fungus species but no longer. is this still around? is there documentation on its proper use?

No specimen, sorry.

Being not well versed in Fungi, I’ve never thought this one would represent a problem in identifying – it really stood out. I usually only collect them for the purpose of getting spores (this one didn’t want to give any :-( The only ones I keep long term are some crusts, hoping I’ll come across someone who can ID them. This one was gelatinous, indeed, and I don’t know ways of preserving something like that long term. If I ever come across the same, I’ll grab it, of course (I go to that location quite often).

did you collect it, Andrew?

that’s the only real way to tell what you have here.

Very interesting mycoparasite.

Yes, you are right, the genus Syzygospora has more than one species (sixteen are listed on Index Fungorum), and these do indeed look like jellies. I assume the texture was jelly like when you handled them. As you noticed, it is hard to find descriptions of other members of this genus, though.

These remind me a bit of Arrhenia auriscalpium with those gelatinous but still gilled forms, although I don’t know of fungal parasites in this group.

I’m bettin’ this is a basidio…

Got scope?

parasite or symbyont

I think it’s some sort of parasite or symbyont like Syzygospora mycetophila (Collybia Jelly). The latter is often mentioned, but what if there are other species seldomly mentioned? I couldn’t find any reference.

I think it’s a mutation?

Armillaria mellea

I know it’s armillaria mellea (most likely) – I collect to eat them every year. What’s the fungus on its pileus? The one that looks like piece of morel or something.

I’m surprised nobody recognized this one – looks very prominent and hard to confuse with anything else.

Super cool!

Maybe Tom Volk knows?
