Asco blanc tourbière
Patrice TANCHAUD, 11-09-2016 10:38
Bonjour,

récolte sur sol en tourbière, parmi les feuilles et les débris herbacés pourrissants. Apothécies 2-7 mm. Spores 15-20 x 3,5-4,5 µm.
Merci d'avance pour vos pistes.

Re : Asco blanc tourbière
Hi Patrice
ths requires more infos. Apothecia gelatinized or not? Asci in Lugol, apical ring shape too indistinct. Living paraphyses?

Re : Asco blanc tourbière
I think Apothecia is not gelatinized. Here is more informations, apical ring is very rarely blue and if it is blue, it is not best than in photo.
Thanks Zotto.

Re : Asco blanc tourbière
Still a mystery. Looks inamyloid, does it? Can you send me this by mail in higher resolution, as jpg better than pdf?

The only idea I have is a Pezoloma. I must look if it fits to one of them.

Re : Asco blanc tourbière
No problem ! I send photos in private.
Thanks.

Re : Asco blanc tourbière
Now the asci are clearly IKI blue, Calycina-like.

It seems to me very close to my Pezoloma cf. obstricta IKI- with spores about 12-20 µm length. You had one collection last year:
X.2015: P. Tanchaud: in Sphagnum bog, apothecia on small rotting stems. Apothecia cup-shaped, without stipe. Asci 105 µm, très faiblement amyloïdes. Spores 11-16 x 3,5-5 µm.

It has slightly smaller spores, but apparently also amyloid. isn#T this the same as presently? Can you tell me the location data of the two, is it the same tourbiere?

Re : Asco blanc tourbière
Yes Zotto, the same tourbiere. BRIGUEUIL (Charente), étang de Roudareix, 7 sept. 2016.
Here Pezoloma obstricta ? http://www.fauneflore-massifcentral.fr/mycologie/pezoloma-obstricta-p-karst-korf-1971.html

Bonjour Patrice, Zotto at tous,

Jean Louis Jalla's find is the same I found last year on Betula leaves and it was commented here on this forum : http://www.ascofrance.fr/search_forum/36456

Patrice latest find's spores look really different , along with the lack of gelitinized texture.

Amitiés
Michel

Re : Asco blanc tourbière
Yes, surely two different species.

Re : Asco blanc tourbière
OK Michel and Zotto. Thanks !
