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.
