Mick PeerdemanHi all,One of my earliest microscopy attempts, so
There were 8 spores per ascus, spores with 8-10 septations per spore, one was seen with 7, most were with 10.?
The spore range was (37) 38 – 53 (57) x 7 – 8 (9) ??m, the average spore from 20 measurements was 43.9 × 7.65 ??.
The green hyphae (Paraphysis??) were amyloid, the spores and asci ddn't react. And the micro pics are mounted in KOH.
More micro pics and info can be found at mushroom observer, here is a link - http://mushroomobserver.org/117014?q=r0co?
Thanks for any help you can provide. :)?
Edit: Or rather, you mean atrata instead of atra?
Edit2: I've found descriptions! :D
Here are some:

Apparently it's world-wide spread, but not always on wood. Here's a photo from my samle, coming from Château de Moha, province de Liège, Belgium, on stems of Verbascum (or eventually Inula).
There's also a little description in Ellis & Ellis.

Thanks for the info, I was mostly confused by how patellaria atra is an old name for a lichen, till I noticed there was also a P. atrata. :) Also, the Ellis & Elli?s books look great, I wish I knew about them sooner!
