Sobre ramitas y hojas de Quercus ilex a 1200 msnm
Ascomas de hasta 1,5 mm y esporas 8-12 x 1,5-2,5 micras.
¿qué diferencias hay con B. clandestina? Hábitat? Tamaño esporal?
Gracias por vuestra ayuda.
Un saludo
Rubén

Re : Brunnipila fuscescens?
Would be important to look for the croziers. B. clandestina without, B. fuscescens and B. calyculiformis with croziers, the latter with longer hairs.
Take care also whether there might be a difference between leaves and twigs. So please measure the hair length. Spore length speaks for calyculiformis.

Re : Brunnipila fuscescens?
Hola a todos.
Gracias por sus respuestas Zotto.
Creo que no tiene croziers, pomgo fotos de ascas de ayer, hoy miraré un poco más para sacar mejor imágenes.
Pelos tienen medida de menos de 200 micras. Luego también mido más.
Sólo tengo muestra de ejemplares de ramitas, los de hojas no traje a casa, es una pena.
Gracias por todo.

Re : Brunnipila fuscescens?
Hola Ruben
with detached asci alone it is almost impossible to be sure. best are young asci that are still attached to the basal hyphae. I know it is not easy. Either a section of living tissue is good, or a strong sqash mount, perhaps by using Congo Red.

Re : Brunnipila fuscescens?
With 150-175 µm only calyculiformis comes into consideration. On one photo I think I see a crozier (the fourth pic, at the lowermost end). But no, the other pics clearly show simple septa.
I never saw this species on leaves. Maybe coriaceous leaves are good for it? Often it grew on Corylus. but also Alnus, Acer etc.
But without croziers it cannot be B. calyculiformis as I understand this species. Perhaps a new taxon...
