AI-generated description

Bolbitius titubans is a species of fungus that belongs to the family Bolbitiaceae. It is a small to medium-sized mushroom with a bell-shaped to conical cap that ranges in color from yellowish-brown to reddish-brown. The gills are free from the stem and the spores are rust-colored. In East and Central Texas, Bolbitius titubans typically grows in fields, meadows, and along roadsides, often in areas with rich soil and abundant organic matter. It fruits in the spring and fall, particularly after rainfall. The fungus is considered common in the region and can be found growing solitary or in small groups.

AI-generated summary of observations

Observations of Bolbitius titubans in East and Central Texas reveal that the fungus grows in fields and parks. On February 28, 2018, yellow fieldcap mushrooms were spotted on Aggie Polo Fields in College Station, Texas. Just a few days later, on March 3, 2018, more Bolbitius titubans mushrooms were found in Bee Creek Park, also in College Station. The fungus appears to thrive in these areas, possibly due to the moist soil and suitable climate. The sightings in late February and early March suggest that the species may be active during this time period in East and Central Texas. The presence of Bolbitius titubans in both fields and parks indicates a wide range of habitats for the fungus. Further observations are needed to fully understand its distribution and behavior in the region. The mushrooms were likely facilitated by recent rainfall.
