Bonjour à tous, voici ce que je pense être Otidea onotica, mais les spores sont plus petites que les tailles généralement données. Qu'en pensez vous ? merci d'avance...

Spores : 9-11 x 5-6.

Asques : 120-150 x 8-11.

Paraphyses souvent courbées aux estrémités.

Pigmentation rougeâtre sur un exemplaire.

Stipe à revêtement blanc.

Hello everyone, this is what I think Otidea onotica is, but the spores are smaller than the usually given sizes. What do you think? thank you in advance...

Spores: 9-11 x 5-6.
Asques: 120-150 x 8-11.
Paraphyses often curved to the extremities.
Reddish pigmentation on one specimen.
Stipe with white coating.

Re : Otidea
Hi, Laurent,
I think ascospores are at the lower end of the range, other characters are o.k.

Re : Otidea
Hi Laurent,

among dozens of other onotica specimens I've seen one czech collection of such small-spored form, warmer part of the country, probably on basic bedrock. Spores (from dead sporeprint) were (9,7) 10,3-11,9 (12,8) × (5) 5,5-6,2 (6,5) um, avg 11 × 5,9 um, Q = (1,6) 1,7-2 (2,2). Otherwise, macro appearance, chemical reactions etc. as in typical onotica. ITS also confirmed O. onotica. 
Did you check the other characters too (excipulum of textura angularis, exudates without change in KOH and melting to amber drops in MLZ)?

Re : Otidea
Hi Viktorie, thank you very much for the clarification,

in fact, this harvest comes from the South of France and in the basic sector. For the other characters (excipulum of textura angularis, exudates without change in the KOH and melting in drops of amber in the MLZ) I have not checked, I do not yet have all the knowledge to do it.
