Yellow asco on Tilia wood
Enrique Rubio, 31-12-2012 17:12
Enrique RubioHi again:

Yesterday I have collected on Tilia wood at 800 m of altitude these small ascomata up to 0.45 mm in diam. with IKI bb asci, croziers (+), some of them with basal globule and + or - lanceolate paraphyses with small yellowish Vb's. Ectal excipulum of an elongate textura prismatica without gelified tissues. 
Hairs in fascicles very difficult to dissociate, + or - yellowish, multiseptate with end cell straight to slightly uncinate, KOH negative.


Maybe a Psilocistella species? because I think it's not an Hamatocanthoscypha as H. uncipila.
What's your opinion?


Many thanks again


Enrique

Re : Yellow asco on Tilia wood
Great! It is very similar to Psilachnum rubrotinctum, which I would place in Cistella, but the spores are too short, and the substrate woody.

Seppo Huhtinen once sent me photos of one growing on wood of Populus but mainly on a resupinate polypore. But the spores are a bit larger than yours (5-8 x 2 ?) , though ?similar.

I attach images (hairs are probably in KOH).

Please check NH4OH for a purplish reaction of the yellow VBs.

Re : Yellow asco on Tilia wood
The ascomata turns quickly reddish with the ammonia vapours as Psilachnum rubrotinctum!

Could be better in Psilachnum?

Re : Yellow asco on Tilia wood
Fine! I don't know such reaction in Psilachnum (with smooth, straight hairs). But also Cistella does not seem to have it. A matter for molecular people.

Bravo Enrique pour cette superbe récolte . Il s'agit d'une nouvelle merveille pour Somiedo, je suppose !
Excellent pour terminer cette année 2012. 

J'espère que Somiedo révèlera ses richesses aux nombreux mycologues que nous recevrons dans ce paradis en juin 2013 !

Amitiés
Michel
