Nouvelle récolte alpine, trouvé sur branches d'Alnus viridis (aulnaie verte à 1'938m), apothécies 0.1 - 0.2 mm, à hyménium blanc, surface externe couverte de petits poils en crochet, renflés à la base, asques à crochets 33 - 38 x 5 - 6 µm, octosporés, IKI-, spores 19 - 27 x 1.25 - 1.5 µm, paraphyses filiformes.
Merci d'avance pour vos avis.
Elisabeth

Re : Unguiculella
Hallo Elisabeth!
this is exciting since I just got a sequence from Francois Valade of a fungus that I would say is the same. But it was on Adenostyles stems in French Alpes, 1800 m, and with the ITS I cannot say where it might belong. Mollisina and Phialina come with great distance. For Unguiculella no sequences exist at all, and I am unaware of a species with such spores.

Re : Unguiculella
Hi Elisabeth,
great finding!!!, no I dea which species it is, the Genus Hyalacrotes should also be taken account of. the species H groenlandica comes close with sporelength but that is all. to be honest, I have no Idea at the time
cheers,
Stip

Re : Unguiculella
Hi Stip
Hyalacrotes I know with glassy and hooked paraphysis tips similar to the hairs. And I see in Raitviir 2004 that all of his have this character.
The hairs here in Elisabeth's fungus are not glassy at all but typical Unguiculella.
A sequence of U. eurotioides or another species would be urgent.

Re : Unguiculella
Hoi Zotto, I see them as glassy although not solid but with a lumen, the photos look as if the paraphyses have the same tips.
It would be interesting to get a sequence out of this species, so Elisabeth if you agree with it and your collection is rich enough I would be happy to give it a try.
cheers,
Stip

Re : Unguiculella
If you try a sequence, we can compare with Francois' one. He got ITS and soon he will get LSU, hopefully.
I recall that hyalacrotes has solid material on the hairs without lumen, and the material disappears in KOH. Here I see a firm but thin wall with a maybe higher refraction index than usual. No, I did not see acute paraphyses, but that feature happens in some of the Ungiculella species.

Re : Unguiculella
just a question: why not a Hamatocanthoscypha?
Best, Lothar

Re : Unguiculella
Hi Lothar
this is a matter of hair shape. In contrast to Hamatocanthoscypha the hairs have a more glassy wall, and they are often +/- geniculate at the junction of inflated base and narrow part. Besides, as Stip said, the paraphyses are actually hooked and also a bit warted like the hairs. Also the inamyloid asci are frequent in Unguiculella. DNA exists for H. laricionis and I could not recognize a relationship to that.

Re : Unguiculella
Thanks a lot, a tiny and beautiful species with exceptional spores, resembles best to the genus Unguiculella, in my opinion no glassy hairs, resistant to KOH, found in a wound on a standing branch, i think the collection is rich enough for a sequence.

Re : Unguiculella
Bonjour Elisabeth, Stip, Zotto, Lothar and all,
Bravo à nouveau à Elisabeth !
If this can help, I have an exsic of U. eurotioides (corresponding to Zotto's file 17 VI 10-1, 2, 3 ) on Urtica dioica 17 06 2010.
I can send it .

Hi Michel
it is a bit old but perhaps worth a try. Mine are also that old.

Re : Unguiculella
Yes it's also what I thought, may be I can send it to Stip as he will receive Elisabeth's collection and decide if it's worth .

Re : Unguiculella
Hi Michel,
thank you for your generousity, we could give it a try but no succes is guaranteed when it is 8 years old. When your collections are large enough there could be enough genetic material I hope.
