Hymenoscyphus / Phaeohelotium ?
Patrice TANCHAUD, 01-08-2018 08:43
Bonjour,

récolte en tourbière acide sur brindille. Spores 11,5-13 x 3,5-4 µm. Asques IKI- et J-.

J'ai l'impression d'être proche de P. fulvidulum ...
Merci d'avance pour vos avis.

Re : Hymenoscyphus / Phaeohelotium ?
Salut Patrice,

Les spores ne sont-elles pas un peu courtes et il me semble que P. fulvidulum est J+

Re : Hymenoscyphus / Phaeohelotium ?
Oui Gilbert, ce sont les deux choses également qui me gênent.

This also seems to have croziers while P. fulvidulum has not. I do not know what this is. The substrate is a twig of a tree?

Re : Hymenoscyphus / Phaeohelotium ?
Yes Zotto, croziers are a big problem for . fulvidulum.

Yes, twig of a leafy tree ("feuillu" in french).

Re : Hymenoscyphus / Phaeohelotium ?
It was right next to ascos on acorn cups of oak I sent on the 28th of July under the object "Hymenoscyphus" (I join photo again), which has spores 10,5-16 x 4-4,5 µm. I have no idea for the moment.
