Habitat

Grassland or Woodland

Leucocybe connata typically grows in dense, tufted clusters on soil or gravel. It is common in disturbed environments such as roadsides, trail edges, parks, gardens, and skid trails near logging operations. It is also found in mixed woodland and on adjacent grasslands, sometimes associated with oak trees or occurring among low herbaceous plants.

Edibility

Not edible

While traditionally considered edible and described as having a pleasant sweet flavor or an asparagus-like taste, this species is no longer recommended due to reports that it contains carcinogens and bioactive compounds like muscarine. It is commonly confused with the poisonous Tricholoma album, which has a bitter taste and unpleasant smell, and the edible Tricholoma columbetta. Beginners should also be wary of the deadly Destroying Angel, though that species possesses a ring and a volva.

Misidentification can be fatal. Never eat a mushroom unless you're 100% sure. This information may be inaccurate. Always consult multiple sources.

Nutrient Source

Saprotrophic

It obtains nutrients by decomposing dead organic matter, such as fallen leaves and wood, found in the soil.
