Pyreno on Populus wood
Enrique Rubio, 04-05-2016 12:55
Enrique RubioHi again

These small (up to 250 microns high) gregarious, scattered, seminmersed, ostiolate perithecia grew on very wet, semirotten wood of Populus. Only the free, somewhat papillate, neck and the apical region of the pyriform ostiolate perithecia are blackish by the existence of agluttinated short hair-like black cells. The rest of the fruitbody is smooth and subhyaline.


The cylindrical, 8-spored, shortly stipitate asci, 90-105 x 8-9 microns, have a highly refractive, small, IKI negative apical apparatus, the stipes not disolving at maturity.


Ascospores hyaline, smooth, 3-septate, 13-20 x 4.5-5.5, with many guttules, with no gel seath, no appendages. Paraphyses septate, apically attenuated.


Have you some idea for it?


Many thanks again
