Roseodiscus? on mosses
Marja Pennanen, 06-10-2011 08:15
Hi,

I have once again difficulties to determine this beautyful pink asco, which I found on mosses on a stone on my own backyard.

These are about 0,3-1 mm wide. They are almoust sessile and seems to grow on dead mosses, maybe they kill them?

The spores are huge compared to those Roseodicuses, whose descriptions I have found: 35-55x6-8. The spores are filled with droplets and are clavate or ellipsoid and can develop 3 septas.
The asci are about 150-200x12-16, IKI blue like Hymenoscyphus and paraphyses are clavate, septate, 3-5 wide and a little exceeding the asci. The marginal cells are a bit clavate, too. Microscophy in photos: 500x.

Is this a Roseodiscus or something else?

Hi Marja

what exotic country do you live? I have no idea. Thanks for the sharp images :-)

Septate spores are unusual in Hymenoscyphus (inside living asci). Did you try a photo of the blue apical ring?

Otherwise I have only one advice: ask Seppo

Re : Roseodiscus? on mosses
Dear Zotto,

I couln't help laughing, when I read your last comment. Quess, what I'm doing here?
I'm following Seppos recommendation ;)

Here's some extra photos.

Only few spores were septate and only these inside living??? ascus.
Is there even 4 septas...

Marja

Ps. winter is close. I think, that if you would meet it  as cold as here, you would find no exotism in our country ;) No exotism, because I live here and will propably die here, too.

Re : Roseodiscus? on mosses
Oh, yes, that is not Hymenoscyphus. Looks more like Calycina, though not fully reaching the apex. Interesting!

Now I remember a fungus that has just the spore size you say, but (3-)7 septate spores. But I suspect yours has more than 3 (from slightl constrictions). If you add something like Melzers you will see the septa clearly.

Yes,

you made it! How on earth did you find that???

Thank you very, very, very much.

Martin independently identified your fungus, and that while he stays in Pakistan :-) I do not know how he was able!

Re : Roseodiscus? on mosses
Hi Marja,

are you sure that the ascospores of your find develop 3 septa? Belonioscyphella hypnorum is known to develop 3–5 septa while B. pluriseptata is described with (3)7 septa (see original description uploaded by Zotto). But as Zotto suggested, I too think that your spores have more septa (I think this can be seen in the fourth photo at the bottom left corner). 

Nice species you found there!

Best wishes,

Gernot

Re : Roseodiscus? on mosses
Hi,

I sent a part of the specimen to Seppo and he confirmed Belonioscyphella pluriseptata determination.

Thank you!
I'm still a little suprised of this determination here.
The collection seems to be the second on this planet ;)
