Fátima Durán ManzanequeHi!! I need help, I found this Ascomycete but I d
Apos < 5 mm, with a big "collarium" at the margin, on deer dungs, 24/11/2012.Asci inamiloid, 8-spores, operculate, croziers ¿? I am not sure.
Thanks.
ça manque de précision sur les dimensions des éléments micros et l'ornementation des spores
Paraphysis with many slightly strangulated septa and mixed with a "gloeocystidia-like" structure with many dots inside ¿?, with a red epithecium in IKI.
Spores (1000x, water)
(16.4) 17.0 - 18.2 (19.0) x (8.7) 9.2 - 10.0 (10.3) µm
Q = (1.7) 1.75 - 2.0 (2.1) ; N = 57
Me = 17.6 x 9.6 µm ; Qe = 1.8
Asci (400x, water)
(220.4) 221.7 - 237.0 (240.3) x (13.7) 14.5 - 18.7 (18.8) µm
N = 14; Me = 230.7 x 16.5 µm
Je suppose que tu as essayé de le comparer à P. cervaria
Amitiés et au plaisir de te revoir à Somiedo

I thought about P. cervaria, macro is more or less similar, but I did not see lateral and base hairs, it is completly smooth. This is the reason I doubt about the genus Pseudombrophila. But I suppose you are right, I have never seen it before.
Thanks.

At Van Brummelen key, P. cervaria has reddish brown or brown disc and P. theioleuca hyaline or white. Mine is not white, but not reddish brown. And my asci have more than 200 µm long. ¿?
De par la présence de pigments bruns entre le sommet des paraphyses, je pense qu'il peut en effet s'agir de P. cervaria (Phill.) Brumm. Je ne suis cependant pas sûr que les ascospores présentées (et mesurées ?) soient matures. A cela deux raisons: la présence de granulations à l'intérieur (je ne parle pas du noyau qui est au centre) et le gélin qui entoure les ascospores, encore que certaines ascospores matures peuvent encore avoir encore du gélin. je remarque aussi que les ascospores sont plus larges que normalement chez cette espèce. Selon Brummelen 14,4-18,7 x 7, 9,9 µm (moyenne 16,6 x 8,8 µm). Je vous conseille de laisser encore maturer cette espèce et de refaire les mesures, sur sporée.
Proche de cette espèce il y a aussi P. theioleuca Rolland, qui croit aussi excréments de chevreuil, mais cette espèce ne présente pas de pigments bruns entre les paraphyses.

I can not say that the spores were fully mature, but I can assure that are measured outside the asci and expelled them without any pressure. They were obtained from the cross sections of the apothecia, in water and mounted without any pressure, only the coverslip. During the observation of the cuts to make the pictures I remember seeing the expulsion of many spores.
Unfortunately the collection is November 2012 and the apothecia are already dry. Next time I collect it, I will wait more time to mature.
Thank you very much for your help.
Cordialement.
