P.D.Orton

Study description
On rotten wood debris in an advanced state of decay, with a conical to expanded cap, with an obtuse umbo, 3 to 7 cm in diameter, surface with greyish radial fibrils on a whitish background, free pink gills due to sporulation, a white cylindrical stipe, a membranous basal volva, a geranium odour, and a mild (insipid) taste.
Cuticle composed of prostrate hyphae arranged parallel, 8 to 20 µm wide, with a slight pale yellowish intracellular pigment, with abundant emergent endings with rounded apices, septate with simple septa.
Cheilocystidia fusiform to lageniform, often with an apical neck, 50 to 110 µm long by 20 to 30 µm wide.
Pleurocystidia scarce, clavate to fusiform, short, 40 to 55 µm long by 15 to 20 µm wide.
Basidia clavate, 25 to 35 µm long by 7 to 9 µm wide, with a simple base and tetrasporic.
Spores ellipsoidal, smooth, thick-walled, pale yellowish under the microscope, 6 to 7 µm long by 3.5 to 4.5 µm wide, with an almost imperceptible apiculus at one end, and inamyloid in Melzer's reagent.
