Hola a todos.
Subo fotos de una Octospora encontrada ayer, entre musgos, en una finca de cultivo de olivos.
Miden hasta 3 mm de diámetro.
Esporas de 17,5-22 x 11,5-13,5 micras.
¿Qué os parece?
Gracias por su ayuda.
Rubén

Re : Otra Octospora
Hola Ruben,
no es O. grimmiae y no es Grimmia pulvinata.
Puede ser O. gyalectoides pero no soy seguro, tu otra Octospora es O. gemmicola.
Saludos,
Marcel

Re : Otra Octospora
Dear Rubén,
in my opinion, you found Octospora gyalectoides (=crosslandii). The spores are typical for that species. The apothecia margin is variable in O. gyalectoides and Benkert (2007) pointed out, that O. gyalectoides probably represents a complex of several species without sufficient morphological differentiation for recognition.
Your arrows show a Pottia, but Didymodon and Pseudocrossidium are also present on your photo. However Pottia is the most common host for O. gyalectoides.
with best wishes
