It was common on living and recently dead oak trunks with lots of moss in the Shasta area. I grabbed a collection but haven’t looked at it yet.

Thanks for elaborating, your reasoning sounds fine to me. :)

why I don’t think its a Tubaria…

spores appear to be hyaline in Meltzers, no spore drop obtained. spores subglobose to obovate…they look like a child’s balloon with their apiculi.

whole mushroom is a buff color, top to bottom, but it’s not necessarily a spore color too.

this is a very small mushroom, with a mycenoid growth habit, growing on an upright living tree.

nothing about it in situ said Tuberia to me.

maybe Oluna would comment? I know she is a student of Tubaria.

What part

rules out Tubaria? I’ve seen them growing in the natural setting before.

Edit: Did you actually observe hyaline spores?

I also thought they looked like a Tubaria.
But I guess they’re not.

no no no

most definitely NOT Tubaria. You may have seen these on Sunday Doug. I showed them to Brian and he guessed some unknown sp. of Xeromphalina, but it’s not that either. Marasmiellus is just a starting point. These were very small and delicate, a pale tan and growing in moss on tree bark. I will scope these today too.

Too bad Dennis wasn’t at the Fair. Maybe he would know.

Kinda look more like Tubaria to me, perhaps?
