Bitunicate pyreno on bark of hardwood with very variable brown septate ascospores

Enrique Rubio, 21-02-2014 18:34

HI to all

I'd like to know some idea about this pyreno on a bark of indeterminate hardwood (Alnus?, Salix?). The pseudothecia, up to 0.5 mm, are inmersed just beneath the surface with an unconspicuous little protruding not laterally flattened black papilla . They seem to be not stromatic and the finely verruculose ascospores are extremely variable with up to 7 transversal thick septa and some vertical or oblique ones, ends obtuse or acute.

Can you help me?

Thanks again
