Pholiotina sp.1
Description: Solitary to scattered agarics, on soil amongst leaf litter, close to Coprinellus disseminatus, under Laurus nobilis.
Pileus: Widely convex with central umbo, vinaceous brown in colour with a darker centre, dry, smooth, striated near the margin; diameter 10-24mm.
Stipe: Thin, fragile, almost straight with slight thickening at the base, pale brown near cap but darker near the base, flesh pale coloured darkening on cutting; diameter 1-3mm, height 30-47mm.
Gills: Free, crowded (L=36, l=0-2), beige coloured changing to rust brown on maturity, with glistening cystidia at the edge.
Spore print: Fulvous (rust brown).

Microscopy:
Pileipellis: Globular cells with intracellular pigment with a lower interwoven filamentous layer. Some globular cells with external deposits.
Basidia: 4-spored, with many immature spores.
Cheilocystidia: Abundant, skittle shaped, with occasional external deposits; 44-87µm x 14-19µm.
Pleurocystidia: Rare similar to cheilocystidia.
Gill Trama: Regular, narrow trama consisting of thin hyphae.
Spores: Pale brown, pip shaped, smooth, without germ pore, darkening in 10% KOH but not collapsing. 6.1-8.4µm x 5.6-6.8µm, Q= 1.07-1.43, Qm: 1.23

This taxon has temporarily been placed in this genus, although I am not fully convinced this is a Pholiotina sp.
