Hello I want to ask you if you have found this ye

Hola a todos.
Pongo unas fotos de un asco que hemos encontrado hoy entre hojas semidescompuestas.
Ascas operculadas, pleurorrincas.
Esporas lisas de 17-19 x 11-12 micras, sin gútulas en el interior.
Pelos algunos con dos puntas, pero la mayoría sólo con una. Miden hasta 450 micras de largo.
Pensé en Trichophaeopsis bicuspis, ¿Qué les parece?
Gracias por su ayuda.
Rubén
did the apothecia grow on or near leaves of poplar-trees (Populus)? That would be characteristic for T. bicuspis. And, of course, the hairs pointed at both ends.
Regards Till
PS: I wonder if the fungus grows exclusively near rotten leaves of poplars.
Gracias por su ayuda, Till.
La recolecta la hice entre hojas de olivos de cultivo, mayoritariamente. Puede ser que hubiera alguna otra de frutales como manzana o pera, pero la mayoría era de olivos.
Seguro que Populus, no.
Saludos

Interesting collection which requires other advices!

Hello together,
I found T. biscuspis some times in my life - typically in leaf litter of Populus (nigra-canadensis). But I also found it in other environments lacking of Populus. Unfortunately, this is quite long ago and I have no documents digitally (I have a digicam only since about 6 or 7 years). But fortunately there should be herbarium material kept in Stuttgart and/or Karlsruhe.
If somebody is planning a monograph of Trichophaeopsis, she or he should perhaps have a look at ther specimens. In this case, I woul do the work and look for them ....
Best regards from Lothar
