AI-generated description

Physarum cinereum is a species of slime mold characterized by its greyish-brown to dark brown sporangia, typically 0.5-1.5 mm in diameter, with a powdery to granular appearance. In East and Central Texas, it has been found on decaying wood, particularly oak and pine, as well as on leaf litter and soil. The species is relatively common in the region's forests, especially during spring and fall when moisture levels are high. It tends to thrive in shaded, humid areas with abundant organic matter.

AI-generated summary of observations

Observations of Physarum cinereum in East and Central Texas reveal its presence in various environments. In Lemontree Park, College Station, Texas, the slime mold was observed covering grass on November 18, 2017. The species formed a distinct black covering on the grass, indicating its active growth and proliferation. Further observations in the same location showed Physarum cinereum growing on grass, suggesting its ability to thrive in this habitat. These findings indicate that Physarum cinereum is capable of colonizing and covering large areas of grass in East and Central Texas, particularly in parks and potentially other grassy environments. The species' growth patterns and abundance in these regions highlight its adaptability and potential impact on local ecosystems. Additional observations are necessary to fully understand the distribution and behavior of Physarum cinereum in this region.
