Tiny black asco on wood
Byrain, 17-11-2012 13:23
Can anyone identify this tiny black fungus on woodchips?  Found in California, USA.

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. :)?

Re : Tiny black asco on wood
Thank you, do you know where I could find a description for this species?  And do you know what the current name is?  Mycobank and index fungorum claim it is Tephromela atra , but that appears to be a rather different lichen, I'm very exeperienced with ascos and am a bit confused. :)

Edit:  Or rather, you mean atrata instead of atra?
Edit2: I've found descriptions! :D

Here are some:

Hi Byrain,
On MycoBank, it's Patellaria atrata:

Classification and associated taxa

Current name : Patellaria atrata (Hedw.) Fr., 2:160, 1822[MB#398671]


Classification : 1. Fungi


2. Ascomycota


3. Pezizomycotina


4. Dothideomycetes


5. Patellariales


6. Patellariaceae


7. Patellaria


Basionym : Lichen atratus Hedw. :61, t. 21A, 1789 [MB#154587]


Obligate or homotypic synonyms : 1. Lecanidion atratum (Hedw.) Endl. :46, 1830 [MB#181476]


2. Lichen atratus Hedw. :61, t. 21A, 1789 [MB#154587]


3. Peziza patellaria Pers. :670, 1801 [MB#148847]


Facultative or heterotypic synonyms : Lichen atratus Hedw. :61, t. 21A, 1789 [MB#154587]


?


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.


 


Cheers - Luc BAILLY.

Re : Tiny black asco on wood
Hi Luc

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!

Re : Tiny black asco on wood
hi brian, i'm so sorry, it was just a type-mistake .. surely atrata.
