Bonjour à tous,

je vous envoie cet étrange ascomycète récolté au sol en Nouvelle-Calédonie (je ne suis pas le récolteur). Il semble tout à fait original, bien qu'il partage quelques affinités, notamment microscopiques, avec Cryptohymenium pycnidiophorum.

La partie centrale, noire, est illustrée sur les photos 3 et 4 : on y observe des loges avec des phialides et des conidies, alors que la partie verte, lobée, contient asques et paraphyses.

Merci pour vos avis !

Guillaume.

Re : Cf. Cryptohymenium
Cher Guillome,

great collection! Indeed there are strong similarities to C. pycnidiophorum described from New Zealand. Do you have spore measurements?

I see in the Landcare database that the species was quite often collected in New Zealand, and also a single sequence exists, regrettably only ITS, which does not show a relationship to Dermateaceae, where the genus is currently placed, but a high distance to everything.

Do you also have a section of the hymenium? It is subapically under a covering layer? I wonder how asci with apical ring can shoot their spores unless the covering layer ruptures before.

Wow!

Re : Cf. Cryptohymenium
Dear Zotto,

thank you for your prompt answer.

I will try to observe a section through the hymenium quickly, and of course I won't forget to measure the spores. The ITS if this colletcion is closely related to Cryptohymenium, but significantly different (93 % of similarity). I asked also for the LSU.

To be continued...

Guillaume.

A you have a sequence. Indeed 7% is pretty much!
