Hello everybody, on decayed hardwood e.g. Quercus
Disco on Carex pendula

Bonsoir tousthis fungus was collected in good condition on damp dead leaves of Carex pendula. Shortly stiped (up to half disc diameter).
* Pale cream hymenium (no hint of reddening with age - this was collected a week ago).
* Hairs roughened; in the lower part often filled with very distinctive globose VB's
* Asci BB, without croziers; occasionally with one to three "Psilachnum guttules".
* Spores narrowly clavate, with a few small oil droplets; 8.5-10.2 x 1.9-2.2µm.
Any suggestions very welcome
Cordialement
Chris

Re : Disco on Carex pendula
Hallo Andreas
A species I have not collected before - at the time I was working on it the only descriptions I had (of Dasyscypha/Dasyscyphus caricis) were in Dennis (1949) and Ellis and Ellis I. Spore measurements and shape were not quite right and Cubby was unavailable so I could not check against Zotto's files.
I can see that the Dennis and Ellis descriptions were almost certainly from dried/dead material - hence the discrepancies. Zotto's HB 8563 is a very good match indeed, with all the characters I mentioned shown. The guttules in the paraphyses and (especially) in the proximal part of many of the hairs are very distinctive - I attach a couple more images of the hairs.
Very many thanks for your (very quick) response, Andreas.
