Geastrum rufescens is a species of earthstar fungus that grows underground before emerging to mature. It has a reddish-brown to tan exoperidium that splits into star-like rays, revealing a pale brown to grayish-brown endoperidium. In East and Central Texas, Geastrum rufescens typically fruits in late summer to early fall, often in wooded areas with rich soil and abundant leaf litter, particularly under oak, beech, and pine trees. The fungus is relatively common in the region, with specimens frequently found in moist, shaded environments.

Rosy earthstar mushrooms (Geastrum rufescens)(?) on Kiwanis Nature Trail. College Station, Texas, December 14, 2021Kiwanis Nature Trail, College Station, Brazos County, Texas, 77843, United StatesObservations of Geastrum rufescens in East and Central Texas reveal that the fungus typically grows under oak trees, often near creeks or water sources. In Bee Creek Park, College Station, groups of rosy earthstar mushrooms were found on December 14, 2018, and again on December 14, 2021, along the Kiwanis Nature Trail. The mushrooms were also spotted in backyards with oak and juniper trees near a creek. Close-up observations showed the characteristic earthstar shape and coloration of Geastrum rufescens. The fungus appears to thrive in similar environments across different locations in East and Central Texas, suggesting a preference for specific tree species and moisture levels. Repeated sightings on the same date three years apart may indicate a seasonal pattern in the fungus's growth and fruiting habits.
