Observation 68434: Callistosporium Singer

When: 2011-05-28

Collection location: vic. Upper Mohihi Stream, Alakai Swamp, Kauai, Hawaii, USA [Click for map]

Who: Oscar Johnson (henicorhina)

No specimen available

Growing off of very moss-covered Ohia (Metrosideros polymorpha var. glaberrima) log in native wet forest. Elevation ca. 1200 meters. Found following three days of light to somewhat heavy rain, so this individual was quite rotten, precluding much in the way of useful field observations.

According to Desjardin, this matches the undescribed species of Callistosporium (burgundy-colored, occurring in wet forest on Ohia logs). Does anyone have any more recent information on this species??

Take a spore sample. The specimen was incredibly soggy. Do you happen to have any insight as to the ID?

did you get a spore print?

this looks a bit entolomataceous judging by the gill color and conicality, but it’s also pretty old.
