Miguel Ángel RibesGood afternoon.Does anyone know this anamorph?It g
J'ai trouvé hier en pelouse calcicole xérique très rase (xérobrometum) ce petit asco qui me fait penser à un Ciboria.
a) diamètre apothécie : 2,5 mm
b) longueur pied : 2 mm
c) spores elliptiques-subfusiformes, à 2 guttules polaires : 18,5-21x8,5-9 µ
d) asques IKI+
e) excipulum à textura globosa, à cellules brunes, les terminales hyalines et cylindro-clavées
f) paraphyses hyalines, à peine élargies à l'apex.

Hi Bernard,
I think this is Sclerotinia trifoliorum.
You have overlooked the sclerotia.
Look at your ascus-foto - you see 4 small and 4 larger spores.
The habitat is quite typical, the species is quite common in meadows, but mostly only solitary or few ascomata.
Best regards, Lothar
Do you know the potential hosts of this Sclerotinia because in this environment there is to my knowledge no Trifolium but many other Fabaceae (Hippocrepis, Anthyllis, Medicago…) ?
Best regards,
Bernard
Hi Bernard,
I fear I cannot help you with this - perhaps the species is not very specialized.
Best regards from Lothar
Bernard
check this database: https://nt.ars-grin.gov/fungaldatabases/fungushost/fungushost.cfm
there are a lot of hosts for S. trifoliorum!
Best regards
Martin
I see that Medicago, Lotus corniculatus and Anthyllis could be hosts of Sclerotinia trifoliorum, which may be suitable.
Best regards,
Bernard
