Hyaloscypha albohyalina ? sur Picea abies
Bernard CLESSE, 09-05-2015 16:38
Bernard CLESSEBonjour à tous,

Voici ce que je pense être Hyaloscypha albohyalina sur partie de tronc complètement pourrie et imbibée d'épicéa commun (Picea abies), à la face infère.

a) asques octosporés, à crochet à la base, IKI+ : 48-60x5,5
b) spores ± fusiformes, parfois un peu arquées, avec microguttules éparses : 7-8,5x2-3
c) paraphyses filiformes, septées
d) poils longuement coniques-subulés 
e) excipulum à textura prismatica

Qu'en pensez-vous ?

Bernard

Good evening Zotto,

Thank you very much for your opinion !

Indeed, it goes to Hyaloscypha fuckelii var. fuckelii with the following data : 

a) Hairs smooth or bearing loose encrustations when fresh in water ; spore mean size 7-8x2 µm
b) Asci with croziers

Here is a picture where you see hair encrustations.

yes, i think spores are too small for albohyalina which has also more oil.
