Extract from Wikipedia article: Geastrum fimbriatum, commonly known as the fringed earthstar or the sessile earthstar, is an inedible species of mushroom belonging to the genus Geastrum, or earthstar fungi. First described in 1829, the species has a widespread distribution, and is found in Asia, Europe, and the Americas. It is distinguished from other earthstars by the delicate fibers that line the circular pore at the top of its spore sac.

Geastrum fimbriatum is a species of earthstar fungus that grows underground before emerging to fruit, typically in sandy soils and under coniferous or deciduous trees. In East and Central Texas, it is commonly found in autumn, often in wooded areas with rich soil and abundant leaf litter. The fungus has a rounded, star-shaped base with 4-7 rays, and a small, rounded spore sac that is usually 1-3 cm in diameter. The outer surface is typically brown to tan, with a fibrous or fuzzy appearance. It is considered a relatively common species in the region, particularly in areas with suitable habitat such as the Lost Maples State Natural Area and the Sam Houston National Forest.

On October 6, 2018, sessile earthstar mushrooms were spotted on Caney Creek Trail in Sam Houston National Forest near Huntsville. The species was again observed in the same forest, but on a different section of the Lone Star Hiking Trail, on July 4, 2021. This time, they were referred to as fringed earthstar mushrooms, highlighting the distinctive features of Geastrum fimbriatum. Both sightings occurred during warm months, suggesting that the fungus may thrive in Texas's summer and early fall seasons. The presence of Geastrum fimbriatum in these areas indicates a potential habitat range within East and Central Texas, with Sam Houston National Forest being a notable location for the species.
