Fungus on Pseudoralfsia algae

estoy estudiando un hongo peritecioide, ostiolado, que nace en el talo de un alga llamada Pseudoralfsia, recolectada en Llanes (Asturias-España). Los peritecios fértiles miden un máximo de 250 micras de diámetro, presentan ascas octospóricas cuyo ápice ascal es I-, y cuyo líquido ascal es dextrinoide. Las esporas son hialinas, con un tabique central verdadero y dos pseudoseptos en los extremos. No pude ver esporas fuera de las ascas, por lo que mis medidas de esporas son de dentro de las ascas. Me = 23,8 × 7,7 µm; Qe = 3,1
He consultado algunos artículos gratuitos en internet de Kohlmeyer, pero no he encontrado nada. Agradecería cualquier ayuda o sugerencia. Muchas gracias.

Re : Fungus on Pseudoralfsia algae
In my region of the northwest Atlantic we get Mycophycias ascophylli on Ascophyllum nodosum (Phaeophyceae). It is on every plant in May and early June. The perithecia and asci seem similar to yours. Maybe a related genus?

Hi David,
The collection of this fungus is from August. I don't know Mycophycias ascophylli, but I will try to look for it in my area. Thank you very much.
