Hymenoscyphus?
Rubén Martínez-Gil, 28-12-2013 01:00
Rubén Martínez-GilHola 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?
yes, undoubtedly confluens.

Thanks, I did not meet confluens yet.

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

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

Un saludo

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 !

Best, Guy

Bonsoir, 

C'est vrai, Guy, il écrit : '' croziers not seen''

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").
