AI-generated description

Marasmius siccus is a small to medium-sized fungus with a bell-shaped to convex cap that ranges in color from reddish-brown to tan, often with a central umbo. The gills are narrowly attached and white to pale yellow. The stem is slender, wiry, and hairy, typically the same color as the cap or lighter. In East and Central Texas, Marasmius siccus is commonly found growing on decaying leaves, twigs, and other organic matter in woodland environments, particularly under oak, pine, and cedar trees. It fruits from spring to fall, with peak abundance during the summer months when humidity is high.

AI-generated summary of observations

Mushrooms of Marasmius siccus were observed growing on catkins on a mossy tree along the Caney Creek Trail (Little Lake Creek Loop Trail) in Sam Houston National Forest, north of Montgomery, Texas, on September 11, 2020. The fungus was found to be thriving in this specific environment, suggesting that it has adapted to the conditions present in the forest. The presence of moss on the tree may have provided a suitable substrate for the growth of the fungus. The observation highlights the ability of Marasmius siccus to colonize and grow on various substrates, including plant material, in East and Central Texas. Further observations are needed to fully understand the distribution and ecological role of this fungus in the region. The discovery of Marasmius siccus in this location expands our knowledge of its habitat range.
