Pyrenopeziza urticicola?
François Bartholomeeusen, 02-06-2014 19:35
Dear all,

FRB found on dead stems of urtica, moist basis between grass and moss.
See photos in attached document.
Macro: gray-blue with whiter edge, young inwardly curled later spread to flat disk.
Micro:  asci 8-spored, long cylindrical, apical ring J +
          Spore: long cylindrical slightly clavate, 8.58 to 10.98 x 2.12 to 2.82 uM Q = 3.85              Paraphyse: long cylindrical
I think it 's Pyrenopezia urticicola (Ellis and Ellis p 442.), But these spores are slightly larger. What do you think?

Sincerely,

François
