Bonsoir,
récolte sur débris de plantes. Spores 10-17 x 1,7-2,2 µm. Avec des crochets à la base des asques, on élimine T. mollissima ?
Merci.

Re : Trichopeziza
Looks like a Trichopeziza, but hairs seem rather short. Paraphyses were typical?
Doesn't look purely white as is required for T. mollissima s.str.

Re : Trichopeziza
Hairs about 130-190 µm (difficult to see where they begin). Here are paraphyses. Yes, mushrooms not white, but yellowish.
Thanks Zotto.

Re : Trichopeziza
So hair length is normal and paraphyses typical. So we can perhaps say T. limonipilosa (ined.).

Re : Trichopeziza
OK, thanks Zotto. I thought hairs were more yellow for T. limonipilosa (ined.).

Re : Trichopeziza
Yes, surely. So at first I also thought T. mollissima, which is not ruled out.

Re : Trichopeziza
Perhaps 2 species ? T. mollissima with croziers and T. mollissima without ?

Re : Trichopeziza
You are right, T. mollissima is mostly without croziers in my folder, but I remember also to have seen white populations H+, and at least one in my folder was clearly H+.
No idea how the situation in the type of T. mollissima was.

Re : Trichopeziza
OK Zotto. Thanks. In my folder all are croziers+ : http://www.mycocharentes.fr/pdf1/1937.pdf

Re : Trichopeziza
Yes but these also show a faint yellowish tint in the hairs and a faint greyish-violaceous in the disc.
