I am seeking assistance with the identification of a specimen that most likely belongs to the genus Dasyscyphella.
Date: 2026-03-25
Substrate: Quercus (decaying stump)
Location: Germany
The microscopic slide was prepared in a 3% KOH solution.
For a more accurate identification, I have attached a PDF file containing macro and microphotographs, as well as a table with spore measurements.
Any suggestions or comments regarding the species would be much appreciated.
Best regards,
Artem
Dasyscyphella-sp.-0001.pdf
As you probably know, Dasyscyphella is caracterized and different fron Lachnum by hairs which last cell (at least) is not verrucose (seems to be the case here)
The most common species (a large part of the year) under hard wood logs is D. nivea. Its spores are rather small
For an appropriate ID, it would be necessary to have further information such as : presence of crystals , Asci with or whithout croziers, spore oil content , width of paraphyses
Do you have H.O. baral's key for the genera ?
The risk with using KOH is do get dead cells , and provide erroneous measurments. Tap water alone is better.
