Yellow Hymenoscyphus (?) on very wet hardwood
Enrique Rubio, 02-10-2012 19:30
Enrique RubioDear friends:
We have collected on very wet decorticated hardwood close to the water level at 1000 m of altitude these gregarious, glabrous, yellow ascomata up to 1.3 mm in diam. They are shortly stipitate by a stout and short stipe or almost turbinate.


The asci have an apical apparatus laterally enlarged, blue or purple in IKI, croziers (+) and the spores are not septate (or only the hypermature ones). Medullary excipulum with textura intricata. Ectal excipulum of interwowen hyphae. Any textura globulosa or prismatica we have seen.  
The paraphyses have low refringent content as fragmenting and cylindrical VB's.

Have you any idea?


Many thanks again
Enrique

Me temo que sí, Raúl. Ya he perdido la cuenta de las veces que me ha engañado.
Gracias

Yes, and I think this is Bisporella confluens. Not much different from B. citrina but spores quite long ans broad.

Thank you Raúl and Zotto
At least it's not a B. citrina!
Have you this paper with the recombination ?

I would very much like to see this paper as well.  Mushroom Observer is undergoing another purging of species names on discomycetes without supporting microscopic data, with particular attention toward Bisporella citrina.

Hallo Enrique,

I'm studying Bisporella on the Belgian coast.
I would be very pleased if I can get a copy of this paper as well.
Many thanks in advance,
