Psathyrella clivensis (Berk. & Broome) P.D. Orton, 1960 (a brittlestem)

Date:	12 May 2004
OS grid ref:	SO71
Lat/Lon:	51° 50' N, 2° 20' W
Location:	Vice County: West Gloucestershire, VC34, England
Voucher:	12/05/2004[P] (Please quote this in any queries about this record)
Stage or state:	Fruitbody
Record Summary:	7 fruitbodies in grass
Identification Notes:	Cap pellucid striate towards margin (say 50%), margin paler, with veil remnants. Spore print: "date brown". Basidia: 4-spored. Spores: 9-10.5/6-6.5, ellipsoid-amygdaliform/ Cheilocystidia: clavate cells ≤15µm wide, occasional fusiform cell. Pleurocystidia: rare, long projecting above hymenium, narrow. Spore shape matches Orton's drawing (from the type material) better than his own collections do! Furthermore Berkeley & Broome were based in the west. Orton's colour ("amber") is presumably an error for "umber" and has been copied by K. van Waveren.
