Hyalorbilia fagi ?
Joaquin Martin, 22-07-2015 23:35
Hi
Collected about branch in riparian forest, coexisting with Orbilia delicatula.
It could be Hyalorbilia fagi.
Thank you.
Best regards.

Re : Hyalorbilia fagi ?
I think it is Hyalorbilia ulicicola. When I try to measure your spores I arrive at approximately 4.5-5.3 x 1.3-1.4 µm. Did you do the photos with oil immersion? Can you send me the original resolution?

The spores seem to me too straight and wide for H. fagi. We have H. ulicicola from Pays Vasca and Navarra, in case you collected there. What could be the substrate? Please tell me the collection data.

Re : Hyalorbilia fagi ?
Thanks for the high resolution. Here I attach a detail from your nice excipulum photo showing the falcate or septum-like SCBs that are very characteristic of H. ulicicola but unknown in any other species of Hyalorbilia.
