« < 1 2 3 4 5 > »
Pulviné, s/ Typha latifolia
Luc Bailly, 29-06-2011 23:06
Luc BaillyBihain toujours, massif de massettes, sur gaines pourries.

Apoth. pulvinées, sessiles, "charnues", minuscules (1/4 mm), complètement furfuracées, cendrées par la translucidité, apparemment hyalines, à marge émoussée à peine visible. Pas très mûr.
Asques 8-sp., sp. bisériées; IKI BB
Sp. mesurées dans l'asque (spécimens pas assez mûrs) 9-10.5 x 2.5-3 µ, hyalines, huile = 0; quelques inclusions sont visibles une fois les sp. hors de l'asque.
Paraphyses cylindriques, un peu renflées au sommet, ne dépassant pas les asques, hyalines, avec quelques inclusions, x 1.5-2 µ.
Exc. ectal de texture pseudoparenchymateuse; pas de poils.

Une idée?

Amitiés - LUC.

Re : Pulviné, s/ Typha latifolia
Hi Luc

that belongs perhaps  in the group of "Helotium" microspis. I cannto tell at present if there are several species which might deserve that name, and which is the correct one.

In England we ha d an abundant collection, but spores were longer and narrower there: *8.3-12.7 x 2-2.7 µm?.

Re : Pulviné, s/ Typha latifolia
here another photo. How is it possible to add several photos at once?

Hi Zotto, it's easy : when you join a photo, you click on "Nouvelle photo" (or perhaps "new photo" for the english users).

Re : Pulviné, s/ Typha latifolia
Thank you, Zotto.
If needed, I know the place quite well, I can check and see if I find further specimens if needed.
Cheers - LUC.

Alain: I clicked nouvelle photo after adding the first, but then the first was replaced by the second.

Here I add a macro of the English find on Juncus

Re : Pulviné, s/ Typha latifolia
Luc, your collection might perhaps better fit to the present one (Mecklenburg, on Glyceria), because of the spores. But this has striking VBs in the paraphyses and marginal cells, which I did not see in the one from England. Maybe your specimen was not alive enough. So if you find it again, please have a look for these inclusions.

Now I try to attach two images....

Re : Pulviné, s/ Typha latifolia
Doesn't work. I attached a drawing by Stip, with the same VBs in the paraphyses, so probably the same species. Here the Glyceria-find:

Re : Pulviné, s/ Typha latifolia
Hi Zotto,

This is very similar, indeed. Okay, I'll check for better samples the next time I visit that bog.
It was very close to the water surface indeed, at the point I'm not surprised it could be an aquatic species.

Cheers - LUC.
