Specimen notes
Public Note:
orange and rectangular, gills broadly attached, length of tall cap, and slightly decurrent. Same as 9358. Possibly arising from a small sclerotium like body - not really a basal disc. Sometimes 2 fruitbodies per sclerotium. Cap a polycystoderm with ramealis covering, strongly dextrinoid.. Not gelatinised. Gill edge concolourous.Spores amyloid 6.6 x 3.2um, 4-spored, patchily cyanophilous. With siccus cheilocystidia. Not Xeromphalina as doesn't have strigose/tomentose base. Not siccus but has clear affinity. Pat has an 'Mycena aff. picta' - probably the same thing and Shirley has a picture of the same taxon under the name M. mamaku. Not Segedin's M. mamaku despite similarity of shape because because that is pinkish buff, brick red in middle, spores with different shape and shorter setulae on cap and cheilocystidia (to 4um). See Maas & Horak's M. detrusa from PNG for more of a discussion on the picta group. Egon says see Marasmius cylindraceocampanulata Hennings from Indonesia but this with inamyloid spores according to Pegler in Agaric Flora of Sri Lanka. Egon's use of Marasmius cylindraceocampanulata has been questioned, and linked to the name Marasmius detrusa aff. However M. detrusa s.s. has has very different cheilocystidia (setula < 1um and cylindrocampanulata to 6um). Egon in his Mycogeography paper says spores 'subamyloid'. So it's not M. c. because of amyloid spores (but cystidia ok) and not M. d. because cystidia incorrect. A new taxon hiding here? Reported to MAF 2/07/2010
