small dark eccentric stem about 1/3 cap diameter is present but not clear in pics. Smell fetid. Cuticle a cutis, monomitic with large clamps, zebra encrustation, not gelatinised, with infrequent and broad 'antler' outgrowths, spores inamyloid (some slightly dextrinoid) 7.3-8.6(8.0) SD0.5, n=7 X 4.1-5.1(4.6) SD0.3, n=7. no rhizomorphs, no caulocystidia seen. Subepidermal tissue only very weakly dextrinoid. (unlike some other Micromphale collections). No white patches on bark. As Marasmiellus nothing in Singer 73 - close to ignobilis. Quite hard to distinguish Marasmiellus from Micromphale. For Singer: rhizomorphs+cuticle ramealis=micromphale,trama gelatinized+no ramealis=micromphale, cuticle ramealis+not gelatinized=marasmiellus. See Wilson & Desjardin Mycologia 97(3), 667, 2005. For them micromphale scattered within gymnopus/setulipes/micromphale clade, and closer to marasmiellus spp. within a new Mycetinis clade (for the M. alliaceus group) - but that diagnosed with central stem, but would be appropriate home if this truns out to be remote from Micromphale foetida (=Gymnopus) and closer to M. alliaceus group. When dry clearly same as 8287, 10089, 10297.
