Specimen notes
Public Note:
stem with sparse tufts of cystidia. Cap edge with powdery cystidia(?), cap hygrophanous with gills showing through. Cap clearly hymeniderm under dissecting scope (thick-walled glassy cells without ornamentation). Gill edge fimbriate. Stem tissue clamped, not dextrinoid, with inflated caulocystidia (to 12um), thin-walled and with sparse extra-cellular brown pigment. 4-spored, spores inamyloid 2.5 x 6.5. Gill trama with very thick walled cells. Cheilocystidia like caulocystidia but with bumps. Stipe base without hairs. M. curraniae has strong garlic smell and larger spores. Horak places curraniae in section with smooth, ramealis hymeniderm pileipellis cells, but draws it with ornamented subhymeniderm cells thus placing it nearer to otagensis. Pat Leonard's provisional key separates the two on the basis of substrate for otagensis being myrtaceae but that isn't a reliable character. Macroscopically Colybia drucei (originally described in Marasmius) sounds similar - except, as a Collybia, it does not posess a true hymeniderm-like pileus. With DNA tube.
