Henri KoskinenHello, would you say this is Peziza or Pachyella?
J'ai trouvé hier, dans un xérobrometum (pelouse calcicole xérique) ce Geopora, semi-hypogé, dans un microsol de 1cm de profondeur.L'apothécie, très fermée, mesure 7 mm de diamètre et l'ouverture de celle-ci a 2 mm.
En ouvrant l'apothécie pour prendre de l'hyménium, quelle ne fut pas ma surprise de voir des petites vésicules. Vésicules qui s'avèrent être des périthèces de Melanospora apparemment.
Que pensez-vous de ce Geopora et ce Melanospora ?

Maybe someone has a pdf of the following article:
Kers, L.E. (1974) - The Swedish Geoporae and their Pyrenomycete Infections. Svensk Botanisk Tidskrift 68: 344-354.
If nobody else has it I can scan it for you and send it tomorrow.
The parasite is indeed most likely a Melanospora species.
Seems to be close to M. brevirostris, spores 25-31 x 13-17 (en face) x 12-14 (lateral view).
Host here was Geopora arenicola.
Best,
Ron

Kers describes one species M. geoporae, but with spores 28-30 x 13-16.
I will scan the article and send it to your private mail.
A very interesting find, I never found these paraites on Geopora.
Best,
Ron
I have that article, sent to both of you.

Hi Viktorie,
could I have the file, too?
Thanks and best regards, Lothar

in my opinion could be the mushroom Melanospora brevirostris, only not ripely. On the last macrophoto one recognizes that some ascomata study a short neck and a few have already studied the dark spores.
The ascomata on my first photo are full-ripe, the host is Geopora/Sepultaria arenicola. Unfortunately, in addition I do not have microphotos.
Here still a screen sequence of Melanospora episphaeria on Hypomyces cf. rosellus. About this species there is surely little informations.
Literature:
CANNON (1982): A re-evaluation of MELANOSPORA Corda and similar Pyrenomycetes....
GARCIA et al. (2004): Two new species of SPHAERODES from Spanish soils
YAO et al. (2007): SPHAERODES in China
GUARRO et al. (2012): Atlas of Soil Ascomycetes
I have the first three documents as PDF.
Greetings Peter.
i am interesting in the paper of Canon 1982. I found Melanospora brevirostris on leporid dung collected in de dunes of De Panne. In this dunes I found also serveral times Geopora arenicola but i had never attention for parasites. You can send it to my mail jacky@launoy.be
Michel.
Best regards,
Bernard
