Re : Hyalopeziza
Dear Elizabeth,
there is no species I can find that fits to your collection, probably another undescribed one. To me it looks like a species related to H. corticicola and alni. the ones with a brown coloured excipilum seems to be genetically unrelated to the hyaline ones and cluster with the Hyphodiscus clade. H. pygmea is placed into a new genus Hyphopeziza that fits there too.
Perhaps Zotto has a idea aboutthe species.
Herzlich,
Stip

Re : Hyalopeziza
I agree, and compared also H. nectrioidea, but that has inamyloid asci.

Valuable would be to make clear if the asci arise from croziers.  I see a young ascus on the lower right of one image which looks like H+. This would mean that only H. alni remains out of these three. But that species has hairs 100-200 µm long, and I believe yours are shorter than 100.

Re : Hyalopeziza
Mit Raitviir 2004 komme ich auf Hyalop. rhododendricola, wo aber das Excipulum dunkelbraun beschrieben ist. Leider sind dort keine Angaben zu den Haken.

Re : Hyalopeziza
Merci Zotto, gestern habe ich im selben Sektor erneut eine grosse Anzahl von Fruchtkörpern auf Calluna gefunden. So rar scheint die Art doch nicht zu sein.

Also ich möchte ja nicht lästig werden, aber das wäre ein Fall für Timo Kosonen, ebenso diese faszinöse orange Ding.
