I would like to make my excuses for the disapearance of the subject Discomycete bleu.
These excuses are above all to Mr. Baral.
I am very sorry Mr. Zotto.

Would you please check this new plate now considered as Proliferodiscus pulveraceus.
Here are the last details :

Date de récolte : 2008.11.06
Forêt de feuillus, érable, hêtre, bouleau
Hôte : fibres assez décomposées de bois mort probablement d’érable
Asques à 8 spores unisériées, avec appareil apical amyloïde
Paraphyses filiformes, cylindriques, jaunâtres en NaCl iso., non septées,1-2 par pied, parfois ramifiées, contenant de nombreuses guttules, dépassant légèrement les asques
Spores cylindro-ellipsoïdes, lisses, semblant non septées, réfringentes, 5 x 2-2,5 µm, 5 x 2,1 µm en moyenne (5 spores), Q = 2,38
Poils cylindriques, parfois légèrement renflés à apex, à paroi épaisse, ± verruqueux et incrustés
Chair (excipulum) gélatineuse, difficilement écrasable à la pression
Cellules de l’excipulum et poils devenant violets en KOH

Thank you ! Roland

Re:Proliferodiscus pulveraceus
Zotto, do you agree now witth our identification of Proliferodiscus pulveraceus ?
Roland

Re:Proliferodiscus pulveraceus
It depends on your test with KOH. If you see such violet reaction I am sure it is this genus and species.

Zotto
Roland Labbé, 14-11-2008 19:08
Re:Proliferodiscus pulveraceus
Zotto, you will see the violet reaction in the excipulum on our photo.
Would you take a look at it please ?
