AI-generated description
Rigidoporus lineatus is a brown rot fungus that causes significant damage to live oak trees. In East and Central Texas, it has been found to infect Quercus fusiformis and Quercus virginiana, among other species. The fungus grows as a crust-like formation on the trunk and roots of infected trees, producing conks that are reddish-brown to dark brown in color. It is often associated with soil moisture and can be found in low-lying areas and near water sources. Infected trees may exhibit symptoms such as decline, cankers, and root rot, leading to significant mortality. The fungus is commonly found in the wild and in urban landscapes throughout East and Central Texas.

AI-generated summary of observations
Rigidoporus lineatus was observed in East and Central Texas, primarily in the Sam Houston National Forest, on various substrates including logs, stumps, and rotting wood of pine and oak trees. The fungus was found in wet areas, near creeks, and on trails such as Caney Creek Trail and Raccoon Run Trail. Observations were made over several years, from 2018 to 2022, with multiple sightings in different locations, including Huntsville, Montgomery, and College Station. The mushrooms were described as shelf or bracket polypores, with zoned caps and tiny pores on the underside. Spores were collected and observed from old oak stumps and wet logs. The fungus appeared to thrive in moist environments, with repeated sightings in areas with access to water.
