One collection from Agrostislsalix herbacea community on Bealach na Ba near Kishorn, Northwest Scotland (Henderson 4910) and with Salix herbacea on Ronas Hill, Shetland (Wat. 17013). 8 pm (Henderson 4911). 41 SUBARCTIC BIRCHWOODS Spence (1974) considers that the birches found in the Western Isles and the remnants on islands in the lochs of Shetland are examples of a former scrub birch copse found presently in the subarctic.

The genus Psathyrella has been found occasionally, in the Scottish mountains but collections await critical appraisal. Members of this genus are not major components of the flora. Panaeolus r1cken11 Hora is not uncommon in base rich montane grasslands. BOLBITIACEAE Several members of the genus Conocybe have been found in montane areas particularly where base rich flushes appear or where limestone or similar calcareous outcrops are found.

G. luteofulva Orton, originally described from England, also has been found in montane regions (The Cairnwell).
