Disco on Carex pendula
Chris Yeates, 07-06-2015 19:37
Chris YeatesBonsoir tous
this 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.
