Appearance

The cap ranges from 2.5 to 7 cm in diameter, and is initially convex before flattening. It has a slight boss that is mustard-, honey- or cream-yellow tinged and steely blue elsewhere. The adnate gills are creamy or lilac-tinged early, and darken with the spores. The slender 5–7.5 cm stipe lacks a ring; it is pale yellow or white with a tinge of the cap colour. The flesh is yellowish and may have a lilac or pale blue tinge. The spore print is reddish brown and the oval to round spores measure 8.5 × 6.5 µm. There is no particular taste or smell. Potassium hydroxide will produce a pink-purple reaction in the stipe or cap. The mycelium is white.
