Pulvinula convexella?

Hola a todos.
Subo unas fotos de una Pulvinula que encontramos en orilla de río dentro de hayedo.
Esporas esféricas de 16-20 micras. Dentro del asca, las esporas ya tienen bien formada una gran gútula con algunas más pequeñitas y que se mantienen en esporada libre. La foto es de esporada libre.
Creo que se trata de P. convexella, ¿Qué os parece?
Gracias por su ayuda.
Rubén

Re : Pulvinula convexella?
A small correction: The ascus base is furcate and does not form croziers. Croziers are defined as forming a complete circle surrounding a perforation.
P. convexella seems to be the current name for P. constellation. Also P. hamastigma seems to be the same (Boud. Pl 406). This has the more yellow-ochre colour of your fungus. I have a folder in Cubby of Pulvinula named "yellow-ochre" (in Ascodesmidaceae) which might fit your fungus.
The spores are originally more multiguttulate (see also Boudier's plate).
