Perithecia globose to pyriform, to 700 mk high, 500-600 mk broad, site among dense weft of brown hyphae on sphagnum branches; dark brown, almost black, upper part setose, base with abundant hyphae, walls firm; all plant (sphagnum) becoming black and firm to the touch. Asci cylindrical, to 200 long, 15-20 broad; paraphyses cylindrical, segmented, 2-3 broad; spores cylindrical, becoming brown in asci, with 1-3 septa, gututlate, 36 (31-41) x 7 (5,5-8,8) (N=20).
Covering densely sphagnum in one spot; S. balticum probably, in wet bog hollow.

Re : Lasiosphaeria from sphagnum
Hi Nina,
as I understand, De Not's description was only published through Saccardo, who marks it with "MS" (manuscript?).
Here are Saccardo's, Schröter's and finally Doebbeler's short text to it. Maybe this helps.
Best regards
Martin

Re : Lasiosphaeria from sphagnum
additional comment: Schröter describes the asci half as long then in your find and more narrow. The spores he observed are bent from the middle part. So maybe a different species as in the desription by DeNotaris/Saccardo where this feature is not mentioned. In the contrary the spores are described there as straight "rectis".

Re : Lasiosphaeria from sphagnum
Thank you, Martin and Alain!
Now Andrew Miller reported me and he would be interesting in work with this specimen professionally, and i will send it to him. I will inform there about the results, as soon as they appear.

Re : Lasiosphaeria from sphagnum
Hello,
This species has appeared in the same spot again, and now the vital characters are seen.
I will email Andrew about this, since he was working with the specimen, and probably there may have be some results already.

Re : Lasiosphaeria from sphagnum
Hi Nina,
have you got the determination yet?
I have found this species for years on Sphagnum in wet, guite shadowed places and am very interested to know, what its is. This is not rare.
When you find it once, you will find it there every summer, if nothing dramatic happens in the surroundings.

Re : Lasiosphaeria from sphagnum
Hello,
Although it has been many years since this was observed, I am interested in whether you were able to confirm this collection as L. muscicola.
To me, the lack of obvious bending in the spores seems to eliminate Hilberina (L.) sphagni and H. sphagnorum, but there is some uncertainty in the literature about the differences between H. sphagnorum and L. muscicola (Svre?k, 1971).
I have recently examined very similar material on Scorpidium, also in bog habitat, which also seems to correspond with L. muscicola.
Interesting that such distinctive species have so few documented observations on the internet that I can see...
All the best,
George
