Cher René

the author of that name is Lorton, not Larson, and it is currently cited as
Chlorosplenium sericeum (A & S) Boud.

For a longer time I have used that name for a very small discomycete, related to Hyphodiscus, with very small spores. That was because an authentic  specimen under that name by Schweinitz belonged to that species. But the colour plate in Alb. & Schwein. suggests that the original concept concerned the larger discomycete with very long spores, and which stains the wood green (= Erinella aeruginosa). I assume you know which of the two you have.

Surely Robert collected in Sugny, Ardennes, which is about 45 km ENE of Reims.

Bien Cher,

Merci pour tes réponses. J'espère que tu vas bien !

Le genre Chlorosplenium a été traité pas Dixon in Mycotaxon  1(2) 1974 et Peziza sericea Alb. et Schwein., espèce type, a été rejeté. Les espèces de Chloroplenium sont des Dermateaceae.

Les genres Erinella Quél, Erinella Sacc. Dasyscyphus Nees ex Gray et Belonidium Mont. & Durieu sont synonymes reconus être des synonymes au genre Lachnum Retzius. Le genre Lachnum ne convient pas non plus pour P. sericea, les paraphyses ne sont pas pointues, mais franchement obtuses et le mycélium colore le substrat, ce qui est particulier. Le genre Otwaya Bearton a le mycélium qui colore le bois en vert, mais la texture de l'exc. ectal est t. intricata,  il y deux types de paraphyses, les poils sont lisses et les ascopores ornementées !!

Je considère ce champignons orphelin de nom !!

Je demeure ouvert à une discussion

Yes, René, you hit the point, as once Ain Raitviir said to me, who also investigated this marvellous fungus.

I actually ordered the type of Otwaya, but it was lost during travel, as far as I remember! The spores are very different, I agree, but for me such sporological features not necessarily result in a separate genus. The dimorphism in paraphyses sounds not very striking to me, only a variation in width. Yes for the excipulum, though also here we have sometimes such variation within a genus.

I got the original sketch and diagnosis from MELU, but this doesn't say much more than the protologue.

Stip took a culture a year ago, and I still hope that we will get a sequence some time.

Actually this is one of my papers that were started years ago but never finsihed.

Did you see the fungus fresh and make any drawings?

Bien Cher,

J'ai travaillé cette espèce et je pense proposer un nouveau genre.

Je t'envoie le travail en privé, y compris avec photos et dessins.
