Discomycète s/ Comarum palustre.
Luc Bailly, 08-02-2012 18:07
Luc BaillyRécolté le 13.08.11, à la face inférieure de feuilles de Comarum palustre. Réserve naturelle domaniale de la Grande Fange de Bihain, Vielsalm, prov. Luxembourg, B., env. 550 m d'altitude.?

Apothécies -> 0.2 mm, en groupes importants, apparemment émergées, chamois clair, sessiles, lisses, à hyménium plan, plus clair, et à marge brun plus vif, mince. Consistance coriace.
Asques 8-sp., sp. bisériées, courts, hyalins, à crochets, IKI BB fort. Peu de spores mûres: sp. guttulées, hyalines, peut-être immatures, 11-12.5 x 3-3.5 µ.
Paraphyses hyalines, renflées au sommet x 3-4 µ, avec une grosse guttule bien réfringente au sommet.
Excip. ectal text. ang. émoussé, brun clair, plus foncé à la marge et près du point d'attache.

Aucune idée...

Amitiés - LUC.

Re : Discomycète s/ Comarum palustre.
Hi Luc

intersting collection! I have only Aivenia tantula in my database for Comarum which appears similar, but spores are only 6-7 x 1.3-1.5.
Mollisia minutissima and Pyrenopeziza comari also exist.

There is a refractive VB in the paraphysis apex. Together with the remaining characters this reminds me of a Calloriella (= Crustomollisia), though a brown cloddy exudate is not visible on the excipulum.

Re : Discomycète s/ Comarum palustre.
Hi Zotto,
This is a nature reserve I often visit, so it's likely I can find more samples.

I do see brown exudates on the photo of the ectal excipulum. Quite clear brown though.

With the paraphyses, and the excipulum text. ang., I excluded Mollisia and Pyrenopeziza.

Calloriella is a genus I haven't seen yet, so, difficult to say. All I have in my refs is a Stip's photo of C. umbrinella on Solidago, and yes, there are similarities (paraphyses, excipulum) with that genus. Is there a study available on Calloriella?

Many thanks, cheers - LUC.

Re : Discomycète s/ Comarum palustre.
Bonsoir Luc

there are similarities between your disco and the one in the post I made on another fungus, for which Zotto pointed me towards Calloriella / Crustomollisia (mine was much more encrusted though) http://www.ascofrance.com/search_forum/16442

I shall follow this with interest

Amitiés

Re : Discomycète s/ Comarum palustre.
Hi Chris,

Thanks for this ref. Yes, my sample is quite close. I didn't notice the paraphyses' reaction to IKI though. My sample is less incrustated, and paler. But this aside, it seems to me Calloriella is a possibility.

Cheers - LUC.

Re : Discomycète s/ Comarum palustre.
I did not speak of an IKI-reaction of the paraphyses, only of very ?striking refractive vacuoles in the apical cell which disappear in the dead state and which you will therefore hardly find mentioned in the literature. But they are very typical for Calloriella.
