Enrique Rubio, 17-04-2009 18:42
Enrique RubioJe vous autrefois prie une aide pour cet asco (0.5-0.7 mm) gisatre, patellarioide, globuleuse et pruinose a la maturesse.
ASci IKI bb, avec des crochets, 8-spored, jusqu'a 125 x18. Paraphyses avec cilindriques et refringentes vacuoles KOH (-). Excipulum textura porrecta gelifiée (non globuloso-angularis). Spores 0-3 septa, multiguttulés, 23-26 x 6-7 que germinent en phialides (¿) brunes.
Je ne connais pas le genre.
Merci en avancé
Enrique

Paraphyses with refractive and cilyndrical VB's turning red brownish in IKI. Excipulum porrecta gelified (not angularis).

Re:Asco on Umbelliferae stems
Wonderful collection! This is my Calycellina "chalarae" nom. prov. (see DVD, HB 6307 + 7429, both on Reynoutria from Gelsenkirchen, and 4262, on Fagus stump, Tübingen. I assume the one on wood is the same species as that on herbaceous stems.

Now Seppo Huhtinen recently wrote me the following: "when checking Velenovsky's types which I brought with me when last time in Praque ... I am rather convinced that your Calycellina chalarae is Belonium betulinum Vel. I also saw the Chalara growing from spores, this time on top of three asci."

So we now have a name, but the generic placement still needs some consideration. I think that Calloriella or Micropeziza are worth to be compared too.

OK., Zotto. I can see in your DVD that is the same fungus.
Many thanks.
