Lachnum sur Fagus

Bernard CLESSEBonjour à tous,

Que pensez-vous de ce Lachnum trouvé sur grosse branche morte et décortiquée de hêtre ?

a) spores fusiformes, sans guttules : 7-14x2-3
b) poils cylindriques, très légèrement enflés au sommet, arrondis au sommet, septés, très finement incrustés (pubescents)
c) paraphyses fusoïdes, dépassant légèrement les asques.

The paraphyses conmtain some VBs, so I think it should be L. brevipilosum. Spores would fit.
Asci should be without croziers in that species, could you verify this?

Good evening Zotto,

Asci without crozier and very few VBs at the top of paraphyses. So, OK for Lachnum brevipilosum ?

Thank you very much,

Bernard

Re : Lachnum sur Fagus
Yes! But this paraphysis is dead and what you saw are LBs which are stable.

VBs I saw in the centre of a paraphysis in the image paraphyse1.
