Trouvé sur branche mort de Salix, ce minuscule Hyaloscyphaceae de forme urcéolée.
Apothécies grisâtres, à marge couverte de petits poils blancs.
Excipulum composé de cellules à paroi réfringente. Poils externes grisâtres. Poils marginaux courts, 22-28 x 3.5-5 µm, hyalins, à sommet obtus.
Asques avec crochet, 68-75 x 6-8 µm, anneau apical IKI + (bb)
Paraphyses sans vacuole.
Spores 8-11 (12) x 2.5-3 (3.2) µm, contenant quelques guttules (OCI=1)
J'ai cherché du côté des genres Olla, Unguiculella, etc. sans succès. Une idée ?

Re : Aide sur Hyaloscyphaceae
I only imagine Protounguicularia barbata (Olla transiens), but the typical hairs are missing. Are ther really true croziers?

Re : Aide sur Hyaloscyphaceae
Thank you Zotto.
I just made a new preparation in KOH 5%. I saw some marginal hairs with refractive tip.
I confirm that asci have crozier at their base.

Re : Aide sur Hyaloscyphaceae
And you do not only ?mean protuberances? because P. barbata has simple septa though crozier-like protuberances. Is the crozier on one of your photos?

Nicolas this is the study of the genus Protounguicularia by Huhtinen (1987)

Hi Pierotti,
thanks for the doc. Do you have more pdfs of the "Beiträge zur Kenntnis der Pilze Mitteleuropas"? I would be interested in it (especially Ascomycetes).

björn

Re : Aide sur Hyaloscyphaceae
About the "crozier", this is much like what you call protuberance (as drawn by Huhtinen, 1987, fig. 1B). I used the term crozier because I thought it could be associated with the "type pleurorynque à crochet libre" as represented by Berthet in his thesis (1964, p. 99, fig. 2).
