Bryoscyphus turbinatus-like on Polytrichum
Georges Greiff, 25-06-2022 22:39
Hi all,

Since I do not have Velenovsky (1934), I would like to get any opinions on this Helotiales sp. found on the lower, dying leaves of Polytrichum commune. Is it one of those featured in that book? To me, it seems to resemble "Bryoscyphus" turbinatus but is smaller in most respects.

Apothecia 60-130 diam, around 40 tall, whitish when wet, yellowish when dry, with a short darker stipe. Excipulum comprising rounded cells of about 7 x 5, smaller near stipe. At margins, short hairs develop up to about 25 long x 3.5-4 wide.

Asci 8-spored, apical apparatus staining blue in IKI. Croziers + (?). Paraphyses narrowly clavate, perhaps minutely verrucose (cannot assess VBs as dead). Ascospores broadly fusoid, hyaline, about 10-12 x 2.5-3.5 (probably a bit bigger when fresh).

Thanks,

George

Re : Bryoscyphus turbinatus-like on Polytrichum
You have it only dry? The ascospores should be shown in ater with their contents, best when still alive. Also the paraphysis contents in water.

The asci seemed to me without croziers but it is not clear.

Re : Bryoscyphus turbinatus-like on Polytrichum
Hi Zotto,

Unfortunately, the specimen is 4 years old from a herbarium specimen of the moss, so I can only observe dead material - not overly useful for this group. I will keep an eye out for fresh specimens in future fieldwork.

Best wishes,
George
