Collection location: Lainzer Tiergarten, Wien, Austria [Click for map]
Under mixed hardwood forests, mostly oak and beech.
On some sort of acorn, not sure which. I looked in the Champions du Suisse Tome 1 for these, and nothing really jumped out at me. I’ll take a look at spores and ascis later, and try and find better Asco sources for central Europe.
Adding some micro-details:
The micro-shot is of asci at 400x in Meltzer’s. The asci are 8-spored, and have slight blue reaction in the tip. The spores are curved, smooth, about 15 × 4 um in size. The paraphases are thin, with blunt ends.
The microscopic details match well with the descriptions of Rutstroemia echinophila from Champions du Suisse Tome 1. Except that species is supposed to be on chestnut husks. But since nothing else matched well, I go with the fact that also goes for acorns at times.

an orange cup on the inside of and acorn cap… i looked through the Fungi of Switzerland book, but found no mention of that being a sole substrate. Please let me know if you run across one like that.
