Phylum: Basidiomycota Family: Hygrophoraceae
Hygrocybe acutoconica (Clements) Singer
Locally common on grazed pasture, especially on sandy substrates like machair and dune-slacks. A medium-sized to robust species, predominantly yellow but often with orange shades in the cap. The yellow stipe is white at the base and often with orange-red at the apex. Large specimens can have a fibrillose stipe not dissimilar to H. punicea but colour will separate them.
