center. Mushrooms beige-tan at first, becoming dingy brown with time, sometimes with a
hint of blue, becoming light beige tawny in
age. Margin even at first, often irregular in
age. Gills dingy, decurrent, broad, running
deeply down the stem. Stem short or sometimes absent.

Distribution Limited to the British Isles,
known from England and Scotland, but not yet
reported from Ireland.

Natural Habitat: Preferring Elms (Ulmus
species) stumps and logs.

Microscopic Features: Spores pale pinkish lilac, oblong and narrow, measuring 12-14 x 4-5
p. Otherwise similar toP ostreatus.
Available Strains: Strains are available from
some British, European and American culture
