Egghead Mottlegill (Panaeolus semiovatus var. semiovatus)
semiovatus
About this plant
Panaeolus semiovatus var. semiovatus, commonly called the Egghead Mottlegill, is a small to medium-sized mushroom with a distinctive egg-shaped cap that becomes more flattened with age. It typically grows on rich, grassy soils, often in pastures or lawns. This species is saprotrophic, meaning it feeds on decaying organic matter, helping break down nutrients in the soil. It is not commonly cultivated for food and should be handled with care as some Panaeolus species contain psychoactive compounds.

Watering. Keep the growing area moist but avoid waterlogging. Water when the top layer of soil feels dry to the touch.
Fertilizing. Since this mushroom grows on decaying organic matter, adding compost or manure-rich soil can encourage growth. No special fertilizing is needed beyond providing a nutrient-rich substrate.
This mushroom grows naturally in nutrient-rich soils, especially in grassy areas like lawns or pastures. It prefers moist conditions but does not require much maintenance. Avoid overwatering to prevent mold growth and keep the area well-ventilated.

Allergy information
Panaeolus semiovatus var. semiovatus is a type of mushroom and is not known to cause typical plant allergies like pollen allergies. However, some people may be sensitive to mold spores from fungi. It's best to avoid inhaling spores if you have mold allergies.
Common problems
Problems can include drying out if the soil is too dry or rotting if the area is too wet and poorly drained. Contamination by other fungi can also occur in cultivation.
Uses
Primarily ecological, helping decompose organic matter in soil. Not commonly used for food or medicine due to potential toxicity.
Notes
If cultivating, maintain moist but not waterlogged conditions and good air circulation to prevent contamination. Handle with gloves if unsure about toxicity.
