[Notes from Kew Type specimen, PRJ 2010] Kew packet has two Colenso collections, b396 and b324. Both were originally anotated on the sheets as "Chrysosplenium omnivirens B", these names edited in red pen (perhaps by Massee) to "Chlorosplenium flavovirens Massee". The sheet has been annotated by Dennis "unpublished?". Dennis (1961) considers the Massee name to be unpublished, and considers the Massee collections to be the same species as Chlorosplenium fuegianum Speg. Dennis transfers the species to Helotium, as Helotium magellanicum nom. nov. (non Helotium fuegianum Speg.). Colenso b324 looks like the same fungus, but apothecia less mature, cup not really opened up as yet. Dixon (1974) considers this specimen to represent an undescribed Cyathicula species (photo of his annotation). Macroscopically the fungus looks like Cyathicula, and Dennis's illustration of the excipulum supports this. Macoscopically the dry discs are dull slightly greenish grey in colour, sides of receptacle near edge of disc with shallow furrows, broad stipitate, shallow cupulate. BAFC2036, Chlorosplenium fuegianum ex Argentina is in the same packet: edge of cup not toothed (cf Dixon's notes; and Gamundi's descriptions and notes, Darwiniana 12, 1962, don't support Dixon's comments); receptacle not ridged as in the Colenso specimen, surface slightly hairy n(2 only apothecia).
