Spores of bladder stalks fungus (Physalacria inflata) collected a day before in Lick Creek Park. College Station, Texas, April 30, 2023Observations of Physalacria inflata in East and Central Texas reveal that the fungus grows on rotting wood, specifically oak logs, in various locations including Sam Houston National Forest and Lick Creek Park. The fungus was observed on multiple occasions between 2018 and 2023, with notable sightings on Caney Creek Trail and Iron Bridge Trail. The mushrooms were found in large colonies, masses, and as individual specimens, often with white caps. Close-up observations revealed details of the fungus's tissues, cystidia, and hyphae. Spores were also collected and examined. The fungus appears to thrive in these environments, suggesting a preference for rotting wood in wooded areas of East and Central Texas.
