Hyaloscypha? Phialina?
Uwe Lindemann, 13-03-2010 11:15
Uwe LindemannHello Forum,
at the end of the last year I found a little hyaline disco on Rubus fruticosus agg. which I cannot determine (see attached document). I think it's a member of the Hyaloscyphaceae but I am not sure about the genus. Is it a Hyaloscypha or Phialina or ...? I don't know. I would be very happy if you can give me some help.

Hi Uwe

das ist Unguiculella eurotioides. The species is a bit variable, but I think yours fits quite well. But the paraphyses should also be hooked! Perhaps you can verify this?

And the asci should be wit croziers, what could be possible in your case.

Hi Uwe,

did you notice any pyrenos with it? On your macro is something black visible. I had a find of U.e. on hedera in January together with a Lophiostoma.

Re:Hyaloscypha? Phialina?
Hi Zotto, thank you very much for your fast reply!
Unguiculella eurotioides fits well to my collection, but I cannot verify wether the paraphyses are hooked or not because the exsiccate is lost. But some of the "hairs" on my photos are not looking like other hairs ;-)
What do you think about the IKI-negative-reaction of the asci in my collection? According to Raitviir 2004 (p.114) the Ascusporus-reaction of U.eurotioides should be blue.
Best, Uwe

Hi Martin,
some minutes ago I read your interesting posting at PilzePilze from january.
There is mabye a pyreno on my Rubus-twig but I can't verify it. The exsiccate is lost.
Best, Uwe

Re:Hyaloscypha? Phialina?
This is strange that Raitviir says MLZ blue for all 4 trated species of Unguiculella. I have quite often seen U. eurotioides, and it was always IKI-. The same for U. hamulata which I saw several times.

Dennis 1949, 1978 does not tell us about the iodine reaction in Unguiculella, but in Sharma & Arendholz 1986 (Mycotaxon 25: 136) the reaction in U. eurotioides is "J-".
