Tricholoma murinum G.M. Taylor & G. Stev. 1964

Description

[GS] Pileus 2-5 cm. diam., mouse grey, darker at centre, convex to plane with depressed centre, velvety; flesh white with a thin grey zone above the gills, continuous with that of stipe. Gills sinuate, pale grey, moderately crowded. Stipe 3-4 x 0-5-1 cm., pale grey above, darker grey with ochraceous tints below, longitudinally striate; flesh silky white when first cut, becoming greyish. Spores 6-7 x 3.5-4.5 um non-amyloid (Fig. 1/31, p . 10). HABITAT: under scrub, Wellington Botanic Garden, 24.6.1960, B. Sneddon in G. M. Taylor (type). [EH] Cuticle cellular to hymeniform with epimembranous pigment encrusted cell walls, clamp connections present. Spores oval, hyaline, neither amyloid nor dextrinoid, smooth, 5.5-7 X 3.5-4 p. Cystidia none. [JAC] spores inamyloid (maybe very weakly amyloid) and cap with obvious spherical cells with brown plasmatic content (like hydropoid vesicles). Attached pigment not seen. Spores glued in tetrads. Not cyanophilous but granular-looking, especially when collapsed. No siderophilous reaction. Not sure about placement in Dermoloma, which I imagine polyphyletic anyway. Certainly not Porpoloma/Tricholoma/Lyophyllum.
