Specimen notes
Public Note:
brown squamules on white background. Centre of cap brown. Spores not metachromatic (?), thick-walled, truncate with germ-pore 11.5 x 8.5 4-spored basidia. Gill edge with brown cheilocystidia vesiculose 15um diam with clamps at base (but difficult to see). Some spores tan in KOH at edge. Cap, in brown centre that isn't squamulose, is a hymeniderm. Flesh turning immediately orange then dark red then brown. Double annulus, not emarginate bulbous base. Vellinga in Aus. Sys. Bot. 16, 361, 2003 has close brunneum/nothorhacodes however this seem to be true rhacodes (FAN5). Notes added March 2008: Material dried a more uniformly brown than those labelled rhacodes. Stem nearly black. Ring is bifurcate, but less obviously than true rhacodes. The brown felty patch is the lower part of the bifurcation but it doesn't have a fimbriate edge. In rhacodes both parts of the bifurcate ring are fimbriate. Brown part of cap clearly a hymeniderm. Cheilocystidia frequently with swollen base and moniliform (lower chains smaller than terminal element) 21.8-24.1(22.7)x10.8-12(11.5), Q=1.82-2.07(1.98). Clamps are present but they are hard to see because they are broad and obscured by the 'swelling' into the next cell in the moniliform chain. This feature has to be the biggest difference to rhacodes. Spore remeasure: 8.7-10.9(9.8)x6.3-7.5(7) Q=1.3-1.52(1.4). Spores seem smaller than other collections. This does not have a marginate bulb! Note than FAN5 synonimises bruneum and rhacodes but later molecular work separates. This is clearly different to others labelled rahcodes but it is not brunneum in my opinion.
