Extract from Wikipedia article: Panaeolus fimicola is a widespread but seldom identified "little brown mushroom" which sometimes contains small amounts of the hallucinogen psilocybin. Panaeolis ater is a synonym.
Panaeolus fimicola is a small to medium-sized fungus with a bell-shaped cap that ranges in color from brown to grayish-brown, often with a darker center. It typically grows on dung, particularly of horses and cows, in fields and pastures. In East and Central Texas, Panaeolus fimicola has been found in a variety of habitats, including prairies, savannas, and open woods, often in association with grasses and other herbaceous vegetation. The fungus fruits in the spring and fall, producing spores that are brown to purple-brown in color. It is considered a common species in the region, particularly in areas with rich soil and abundant organic matter.

AI-generated summary of observations
Observations of Panaeolus fimicola in East and Central Texas reveal its presence in lawns, particularly in Lick Creek Park, College Station. On June 21, 2018, the fungus was found alongside Agrocybe retigera and Parasola, indicating a diverse range of species in the area. Later, on September 11, 2018, Panaeolus fimicola was again observed, this time with Coprinopsis mushrooms, suggesting its ability to coexist with other fungi. The fungus appears to thrive in lawn environments, potentially benefiting from the moist and nutrient-rich conditions. These observations highlight the presence of Panaeolus fimicola in East and Central Texas lawns, particularly during the summer and early fall months. The species' adaptability and ability to coexist with other fungi make it a notable component of the region's mycological landscape. Its growth patterns and interactions with other organisms warrant further study.
