AI-generated description

Mycena clavicularis is a small to medium-sized saprotrophic fungus with a bell-shaped cap that ranges from 0.5-2 cm in diameter, typically grayish-brown to pale brown in color. The gills are crowded and attached, with a similar color to the cap. Stems are slender, 1-4 cm long, and usually equal in width throughout. In East and Central Texas, Mycena clavicularis is commonly found growing on decaying wood, particularly oak and pine, in humid environments such as forests, wooded areas, and along streams. Fruiting bodies typically appear from spring to fall, with peak abundance during the summer months.

AI-generated summary of observations

Mycena clavicularis was observed growing in pine forests and wooded areas in East and Central Texas, particularly in the Sam Houston National Forest and Huntsville State Park. The mushrooms were found on or near pine needles, often in large groups, and typically had slimy stems. Observations were made from October to December over several years, with frequent sightings in November and December. The mushrooms were found under various tree species, including pines and oaks, and on different substrates, such as forest floor duff and accumulated pine needles. Close-up observations revealed the characteristic features of the species, including its bonnet-shaped cap and slender stem. The mushrooms were often found in areas with abundant pine trees, suggesting a possible association between the species and pine ecosystems.
