Je 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
Ascomata 0.5-0.7 mm, greyish, bluish, patellarioide, convex, (sub) sphaeerical and pruinose at maturity. Asci up to 125 x 18, 8-spored, IKI bb, with croziers. Paraphyses with refractive and cilyndrical VB's turning red brownish in IKI. Excipulum porrecta gelified (not angularis). Spores up to 3 septate, muliguttulate, hyalines, 23-26 x 6-7 germinating in brownish phialides (?).
I don't know the genus it belongs.
Many thanks

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.

Re:Asco on Umbelliferae stems
OK., Zotto. I can see in your DVD that is the same fungus.
Many thanks.
Many thanks.
