Asco sur tige pourrie d'ortie (Urtica dioica)
Bernard CLESSE, 04-02-2017 21:31
Bernard CLESSEBonsoir à tous,

Que pensez-vous de cette récolte sur tige pourrie d'ortie (Urtica dioica) ?

a) poils ± hyalins, septés, incrustés légèrement, arrondis au sommet, à parois assez épaisses, graduellement rétrécis  
b) asques sans crochet à la base, IKI+
c) spores étroitement fusiformes, multiguttulées : 19-24,5(33)x3(-5)
d) paraphyses lancéolées, plus longues que les asques

A pity that this seems badly developed. Did you measure the hairs? They seem to me rather wide for a Trichopeziza?

Hi Zotto, thank you for your message. I'll check the measures of the hairs in a few minutes.

Hi Zotto,

Here are the measures of the hairs :

a) length : 125-160 µ
b) width : 3,5-5 µ

o.k., it seems not too wide for Trichopeziza. I am obliqued to believe in spore 2 as typical, but with such a large size I cannot guess any species.

OK thank you Zotto !

Perhaps the significant freeze damaged this Trichopeziza…

Perhaps the important cold has damaged the asci (no spore observed in the asci) and abnormal spores.
