Specimen notes

Public Note:

spores amyloid to 6x 3.5um, flesh of cap yellow and with copious arthrospores in cap tissue. This is looks like C. jasonis (sensu B&K4). Interesting that arthrospores are also present in Stevenson's drawing of C. clastrotricha but not explictly mentioned by her, or Horak in his redisposition, who says 'more than 4 species in NZ'. But Stevenson't taxon is on wood in Nothofagus forest and has smaller spores and a more slender appearance. C. amianthinum doesn't have the arthrospores or yellow cap flesh. Recent work on this material has show it to be C. clastotrichum and LSU sequences align closely with C. japonicum which has inamyloid spores (and should be in Cystodermella?). See AM946490 http://www.ncbi.nlm.nih.gov/entrez/viewer.fcgi?db=nuccore&id=169977247 and paper in Mycological Progress 2009.

Public Note:

The synonymy of C. clastotrichum with C. simulatum, as implied by Saar et al 2016 is highly unlikley.
