Hi againThis another one is 1-1,5 mm, subsesil, in Pinus sylvestris, hymenium yellow-orange, outer surface covert with apparently white hairs. Microscopically it remembers me Lachnellula subtilissima, but it is too small and all the apos are very closed, not completly open at maturity like L. subtilissima.
Thank you,
Miguel Ángel

Re:Lachnum / Lachnellula
Your apos are quite big and open, typical of Lachnellula subtilissima when rehydrated. Also from the substrate there is nothing else to be excpected. Lachnellula subtilissima is variable, having usually hemiamyloid but also inamyloid asci, even the croziers vary. Lachnellula calyciformis has more fusoid biguttulate spores and always inamyloid asci.
You should try a section with a sharp razor blade then you are sure which are the hairs. they must be distinctly rough-warted,
Cheers

Re:Lachnum / Lachnellula
Thanks Zotto, I never had seen so small L. subtilissima...
I made more than ten sections at the margen with a razor blade, taken only "white material", but all the times I only obtain an amorphous mass. The best one is the photo I attached yesterday, so I am very surprised because all the otrher Lachnum sp. hairs I had seen before were very easy to recognize and to make a photo... :( Mistery :)
Thanks again
