Pezicula livida
Típica la reacción hemiamiloide en Pezicula. En Melzer no hubieras visto la reacción...

Re : Ascomicete en Picea
Yes, ot from the long spores I would rather guess P. eucrita, a species with predominantly 4-spored asci. Did you see any asci with more than 4-5 spores?

Re : Ascomicete en Picea
Gracias Raúl y Zotto.

La mayoria de las espores tienen 4-5 esporas maduras junto con otras abortadas, lo maximo que he visto son 2 ascas con 6 esporas maduras.

Esto es P. eucrita?

Saludos

Re : Ascomicete en Picea
Sí Javier, Zotto tiene razón... Me he dejado llevar por la morfologia esporal que me ha recordado más a la la P. livida.

Raúl

Re : Ascomicete en Picea
From my memory I don't think that P. livida exceeds 30 µm. I gave 22-30 in 1985, and Dennis says 22-24. But it is difficult to trust the literature. Ellis & Elis say 22-32, but did they separate between the two?
Verkley says L:W ratio 3.5-5 for eucrita (including rare 8-spored form), average 26.5-33 x 5.8-7
and <4 for livida (which he subsumed under P. cinnamomea) L:W 2.7-3.2(-3.4), average 18-24.3 x 6,5-9
