Cryptodiscus on Pinus
Hans-Otto Baral, 16-10-2009 18:44
Hans-Otto BaralHere is another Ostropales mystery. Obviously close to Cryptodiscus foveolaris but excipulm dark red-brown. I have seen two collections. Apparently indeterminable with Sherwood.

From Grenoble (Villard-de-Lans) and Mont Ventoux, on xeric decorticated Pinus sylvestris branches, soc. Pseudevernia furfuracea, Orbilia montigena. Ap. rehydr. 0.5-1 mm diam. Asci *32-40 or *47-52 x 8-9.5 µm, 8sp., fusoid-clavate, apex subtruncate, outer wall IKI 3Rb/RR, dome restricted to apex, 5->2 µm thick in dead state, laterally thin-walled. Sp. *6-8(-10) or 9-11(-12) x 1.8-2.2 µm, 0(-1)-septate inside living asci, 1-2 small LBs & somet. one 1-1.3 µm near each end. Paraphyses apically +/- knob-like.

Re:Cryptodiscus on Pinus
The spores were usually straight but also allantoid. Not many asci were mature.

Re:Cryptodiscus on Pinus
Hi Zotto,

great, I think you found my fungus: http://ascofrance.com/index.php?r=forum&page=viewtopic&id=7519&highlight=ostropales#msg7519

Did you find your fungus on calcareous soil? And at what sea level?
Hopefully you come to a better solution.

Best wishes,

Gernot

Hi Gernot

Ufff, I totally forgot your find. Yes, it looks much the same! But are you sure wit Fagus? The wood could also be coniferous from its appearance. Could you please look for the wood anatomy (cross break)?

From where did you have it? Mine are from calcareous alps, yes, one is from 1200 m, the other 1400m.

Now I found a name for it, hahaha: Cryptodiscus 'rubrobrunneus' on DVD, HB 7292, on Pinus sylv. too, From Escorial near Madrid, 1330 m. I suppose there acid soil but I am not sure.

Re:Cryptodiscus on Pinus
well, actually Pinus could be possible. I found it twice, both time under Fagus, with Pinus next to it. Nevertheless, I was quite sure about Fagus but I will check on it again (and I will try to collect new fresh material).

My first one was from Austria, Styria, Bruck an der Mur, St. Ilgen, Karlschütt (extremely calcareous soil, 900 m; mixed Picea-Pinus forest with single Fagus trees) and the second one from Austria, Styria, Leibnitz, Demmerkogel (not sure about the soil - at least partly acidic, 670 m; mixed forest with Picea, Pinus, Quercus, Fagus and Castanea, very thermophile).

I'm glad I can give the fungus now at least a name which one can find on your DVD. Than I have something to refer to :)

Best wishes,

Gernot

Re:Cryptodiscus on Pinus
Hi Zotto,

yesterday I went to the area where I found Cryptodiscus "rubrobrunneus" at first. It is astonishing how common the fungus is there on fallen branches of Pinus sylvestris! Everything was very wet too, because of lots of rain and the first snowmelt so it was not hard to find the Cryptodiscus.
After these new results this species seems to be restricted to Pinus, at least for the findings up till now.

Best wishes,

Gernot

Re:Cryptodiscus on Pinus
Wonderful and strange! It will be hard to find out what characters all these old names of Cryptodisci have. F.ex. there is a Cryptodiscus pini (Romell) Baloch, Gilenstam & Wedin, Fungal Diversity 38: 64 (2009)! Yes, it obviously seems to be this species, see the article:

http://www.fungaldiversity.org/fdp/sfdp/FD38-3.pdf

Here is an image from this paper which presents only rather worse microdrawings.

Re:Cryptodiscus on Pinus
that is great, the description really fits well with our finds. I am thankful that you found a name for this species!

Best wishes,

Sherwood described a new genus Paschelkiella for our (Romell's) fungus. see

Re:Cryptodiscus on Pinus
thanks again! It's interesting that she is writing about apparently always 1-septate spores whereas our finds had mainly 0(-1)-septate spores.

Best wishes,

Gernot

Re:Cryptodiscus on Pinus
Yes, you are right! That might come from the age of their material, but also Baloch et al. say only 1-septate. In USA the fungus is said to occur also on Libocerdus, in Sweden only on Pinus.

Re:Cryptodiscus on Pinus
I will try to check on yesterday's material when it is older and dried, maybe then there will be more 1-septate spores than in fresh material.
Apart from the spores everything else matches good so I have no doubts that we are right with Cryptodiscus pini.
