Hola a todos.Tengo esta Dermea que no me encaja co
Last week-end we have collected these small, gregarious, pale witish or amber (when old), subturbinate or shortly stipitate up to 1mm high and 0.7 mm broad ascomata growing on male cones of Pinus radiata lying on the wet ground. It seems to have any blackened stromatized zones at their insertion on the host.
The hymenium is never convex but it is plane to slightly concave.
The ascospores are smooth, broadly fusiform and they seem to have 1 nucleus.
Asci with croziers, 8-spored, with an apical apparatus weakly euamyloid, very difficult to observe and I don't know their type (Sclerotinia-type, Hymenoscyphus-type?) .. Living paraphyses with many rounded Vb's, hyaline to yellowish.
Ectal excipulum is built by roundish to vesicular cells in a tetura globulosa-subangularis. No hairs in the apothecial margin; only cilyndrical to subclabvate elements with the same Vb's.
I think perhaps this fungus belongs to the Sclerotiniaceae or Helotiaceae. I'm not sure...
Many thanks for help me
Yes Enrique, the EE is noticeable with the raher globose cells and cylindrical 1-2 septate protuberances with high vacuoles content . I also noticed it on Pinus needles with Desmazierella acicola and ond Cedrus buds (see attached pic) .
Au plaisir de se retrouver bientôt en Asturies
J'avais tes belles photos de cette espéce.

Enrique was right to doubt between Sclerotiniaceae and Helotiacea, Svreck described this taxon on Hymenocyphus ravus and.........Ciboria rava !
Amitiés à tous
