Hola a todos.Pongo unas fotos de este asco que encontré sobre madera, creemos de Juniperus communis.
Miden hasta 5 mm de diámetro y tienen un pseudopie de 1 mm.
Esporas de 15-21 x 4-5,5 micras con 1 septo central trasversal.ç
Excípulo ectal no lo había visto nunca, es nuevo para mí.
Gracias por su ayuda
Un saludo
Rubén

Re : Hymenoscyphus?
Hi Ruben,
the apical pore shape is no hymenoscyphus but Calycina type, your species resemble highly to Bisporella (with gelatinized excipulum) B. citrina the most but your sporemeasurements do not fit. So I would say perhaps a undescribed or for me unknown species of Bisporella
cheers,
Stip

Re : Hymenoscyphus?
Hi Ruben, Stip, and everyone,
I agree, Stip. Then, how about B. (Calycina) confluens ? The spore size would fit better.
Amitiés
Michel

Re : Hymenoscyphus?
confluens is a species that is gradually linked with citrina, not clear cut in every case. Perhaps therefore the name confluens ;-)

Hola Stip, Michel, Zotto y a todos.
Gracias por vuestras respuestas, yo no conocía la existencia de B. confluens.

Re : Hymenoscyphus?
Hi Zotto and all,
I don't have the paper with me to certify, but when Korf & Bujakiewicz* have proposed the new combination Bisporella confluens, this species is described without croziers !

Re : Hymenoscyphus?
Yes, it is true, and the spore size is smaller. But the asci are not figured. In that paper only N-American specimens are cited. So this species needs reinvestigation, also for the apical ring type ("very slightly blue in MLZ, enhanced by KOH").
