Lachnum crème sur Typha latifolia.

Même site. Il y en a, des espèces, sur Typha.Apoth. très courtement stipitée à subsessile, poilue, à marge longuement ciliée. Taille: =>0.3 mm. Hyménium plan ou quelque peu bombé. De couleur blanchâtre, crème, pas blanc pur.
Asques 8-sp., spores bisériées; IKI B, petit appareil apical. Crochets non vus (j'ai cherché, mais rien trouvé). Taille: 25-32 X 4.5-5.5 µ.
Spores parfois légèrement "triangulaires", avec peu d'inclusions (huile= (0)1(2)), non septées, 9.5-11.5 X 2 µ.
Paraphyses dépassant nettement les asques, lancéolées, guttulées, X 2-3.5 µ, septa non vus.
Poils acuminés au sommet X 2-2.2 µ, granuleux, sans cristaux d'oxalate (ou alors, les cristaux se détachent très vite et je ne les ai pas vus).
Pas d'idée.
Amitiés - LUC.

Re : Lachnum crème sur Typha latifolia.
Dear Luc
I see only dead paraphyses and hairs, so it is difficult to say something. The granulation might be oil instead of VBs. The hairs should be better seen, I do not think they are really acuminate, maybe a bit tapered. Lachnum carneolum would have such hairs, but this has croziers and would turn red-brown.

Re : Lachnum crème sur Typha latifolia.
The paraphyses were all in the same condition... :/
I might check again the hairs and the asci for croziers, with some Congo red.
I'll also check if there's no evolution in what remains of the sample.
I've picked that sample two days after the rain, just after a long dry preiod.
Cheers - LUC.

Bonjour Luc,
this is hard to see granulation indeed, i am not sure about that. The Fruitbodies resemble to me also like Psilachnum.....
Cheers,
Stip

Re : Lachnum crème sur Typha latifolia.
It might be a Psilachnum, indeed.
I probably took a bad specimen. Here's a preparation in Congo SDS (to see if there were croziers, I didn't notice croziers here neither).
Paraph. septate, 39-55 x 4-5 µ
Hair up to 55 x 2-2.5 µ
Thank you Zotto & Stip.

Re : Lachnum crème sur Typha latifolia.
Yes, Psilachnum, Stip was right! I would say P. acutum, but all finds I saw had asci with croziers. Yours look without, but I would need to see that from more images to be sure.

Re : Lachnum crème sur Typha latifolia.
I have more images I can email to you if you want.
P. acutum was also what I was thinking about, at first sight.

Re : Lachnum crème sur Typha latifolia.
Thanks, Luc, for sending further images. Absolutely without croziers. That will be a matter for a coming monographer :-)
Oh, now I see your fungus should be Psilachnum lateritio-album. That species is without croziers, at least from my finds.

Re : Lachnum crème sur Typha latifolia.
Thank you, Zotto. I found it on the DVD, and indeed, it matches fine.
My sample was gathered just above the water level also, BTW.
