This bright yellow mushroom, which grows singly or in small clumps and fades with age, is found in plant pots and occasionally in glasshouses. The cap surface is smooth but dotted with fine, easily detached scales, and often develops shallow, radial grooves near the margin. A tropical species that has been introduced into New Zealand.

Gills: free, crowded, thin. Pale yellow to whitish yellow. Edges smooth.
Stipe: 40-90x 3-6 mm, slender, hollow, fragile. Yellow, sometimes paler toward the base. Ring thin, fragile, often disappearing with age. Base sometimes slightly swollen.
