Hello all,

A small Diatrype that I cannot identify.

On dead branch of Acer sp. (platanoides or campestre), directly on dead pseudothecia of Massaria sp.


Stroma 1-1.5 mm in diameter, discoid. Entostroma developed.


Ascospores 6-7.5 x 1.5-2 µm, allantoid, pale yellow-brown, smooth.
Asci long stipitate, pars sporifera 20-25 x 5-6 µm, with non-amyloid apical apparatus, even with KOH pretreatment.


thank you in advance for your help


Andgelo

Re : Diatrype sp.
Hola Andgelo, con estas medidas esporales y sobre Acer, las claves llevan a la Diatrype spilomea, pero su aspecto no me cuadra en absoluto.
Saludos.
