Artem PtukhaHello, I am seeking assistance with the identific

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
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).
