Lachnum blanc s/ Carex paniculata

Luc BaillyBonjour à tous,
Voici un indéterminé restant de l'an dernier.

Lachnum S/ feuille de Carex paniculata. RND Anciennes Troufferies de Libin, Ardenne belge, 29.11.12.

Apothécies en groupes, ~ 2/3 mm, blanches, devenant d'un jaune très pâle. Pseudostipe très court.
Asques 8-sp., bisériés, IKI BB, 55.5-69 x 6-7 µ. Crochets non vus, sans doute absents.
Paraphyses lancéolées, septées, lisses, dépassant nettement les asques, 88-93 x 4-7 µ par exemple.
Spores allongées, fusiformes à subcylindriques, fortement guttulées, (10.5) 11.5-19 x 2-2.2 (2.5) µ.
Poils hyalins, cylindriques, parfois légèrement clavés au sommet, un peu verruqueux, x3.5-4.5, peut-être un peu plus.


Pas d'idée.?


Amitiés - LUC

Re : Lachnum blanc s/ Carex paniculata
Hi Luc

I think it is L. juncinum. The spores are a bit narrow  (I know 2.5-2.7 µm). A problem is that the paraphyses and hairs should be multiguttulate when alive. Your hairs seem dead but the paraphysis is alive and empty. Do you still have fresh apos to control another?

L. juncinum turns reddish with age because of these VBs, yours not?

This is a very rarely reported species.

Re : Lachnum blanc s/ Carex paniculata
Hi Zotto,
Nope, the sample has faded, alas. I got it late in the season, after already a cold night and cold wind, that could explain.
I still had no red tint, only pale yellow. The sample looked still very fresh when I found the apothecia's.
I looked at the photo's, all was in that state.

Hopefully, that's a bog I know well and where I can return. Does this species grow during Spring also? If so, I'll probably have the opportunity to make other sampling campaigns on the site for more lists in that nature reserve.

Cheers - LUC.

Re : Lachnum blanc s/ Carex paniculata
Chances are big I return to that bog during Spring. If so, I'll check on Carex paniculata, which is present in big populations.
Cheers - LUC.
