Flowerpot Parasol
Leucocoprinus birnbaumii
Type: gilled mushroom

Physical Characteristics
Bright lemon-yellow to sulfur-yellow throughout. The cap is oval when young, becoming bell-shaped or conical with age, covered in fine powdery scales. The gills are free from the stem and crowded. The stem is thin, often with a fragile ring and a slightly swollen base. Spore print is white.
Habitat & Growing Conditions
Commonly found in indoor potted plants, greenhouses, and compost piles. It thrives in warm, moist, nutrient-rich potting soil containing high amounts of organic matter.
Season & Fruiting Time
Indoors, it can occur year-round. Outdoors, it appears in summer and autumn in tropical or subtropical climates.
Similar Looking Species
Leucocoprinus sulphurellus is similar but often has a blue-green bruising reaction. Leucocoprinus ianthinus is similar in shape but has purple or lilac tones on the cap.
Ecological Role
Saprophytic; it breaks down organic matter in the soil or potting medium, contributing to nutrient cycling within the planter or ecosystem.
Safety reminder
AI mushroom identification is a best-effort estimate and can be wrong. Never use it to decide whether a mushroom is safe to handle or eat — always confirm with a qualified mycologist before any consumption.
