Extract from Wikipedia article: Rickenella fibula or Omphalina fibula is a species of fungi that belongs to the genus Rickenella. The cap is quite small, with a diameter usually less than 1 centimetre (0.4 in).
Rickenella fibula is a small, brightly colored fungus that grows in grassy areas. In East and Central Texas, it typically fruits in the spring and fall, producing tiny, orange to yellow-orange caps with a fibrous, hairy appearance. The fungus is often found in moist, shaded environments, such as along streams and under trees, particularly in association with mosses and other small plants. Its distribution in the region appears to be widespread, but sporadic, with records from various counties, including Brazos, Grimes, and Travis.
