CS102 Buskett (13/10/10)
Description: Small ephemeral and delicate agaric, partially auto-digesting, solitary to scattered on soil and leaf litter (leaves of Laurus nobilis and Quercus).
Pileus: Conical to flat without upturned margin in the mature specimens. Coloured grey-brown with a yellow-brown central area, sulcate almost to the centre with occasional splitting at the margin. Pileus diameter of collected specimens 7-16mm wide (young specimen 12mm wide, 10mm high). Velar remnants on pileus absent. Setae or hairs absent.
Stipe: Cylindrical, sub-bulbous at base, hyaline without colour change on cutting and thin 1-2mm diameter. Height range: 20-28mm.
Gills: Dark grey with a black edge to completely black, distant, free. l=1
Spore print: Black.

Pileipellis: Atomate (diameter 22-23µm, length 27-46µm)with a lower layer of interwoven filamentous hyphae.
Cheilocystidia: Abundant in bunches, large and cylindric to skittle-shaped; diameter 18-28µm, length 28-46µm.
Pleurocystidia: Present as large elongated cells - not abundant; diameter 23-25µm, length 55-60µm.
Basidia: Narrow and 4-spored
Spores: Ellipsoid when seen laterally, but similar to corn kernels (or heart shaped) in face view, smooth with germ pore (lateral in face view). L=10-12.0µm, 5.8-6.8µm lateral width, Q: 1.48-1.70; 7.6-9.5 face view width, Q: 1.08-1.45; Germ pore small 1.9-2.2µm, hilar appendage conspicuous.
