Extract from Wikipedia article: Mycena alcalina, commonly known as the stump fairy helmet mushroom, is a species of fungus in the family Mycenaceae. It grows widely, ranging from North America to Europe.
Mycena alcalina is a small to medium-sized fungus with a bell-shaped cap that ranges in color from pale yellowish to grayish brown. It has a slender stem and grows in clusters on decaying wood, especially oak and elm. In East and Central Texas, it typically fruits from spring to fall, often in wooded areas with rich soil and abundant leaf litter. The fungus is widely distributed across the region, including the Edwards Plateau and the Piney Woods ecoregions.

AI-generated summary of observations
Mycena alcalina was observed growing on various substrates, including fallen pine logs, rotting pine wood, and mossy pine logs, in East and Central Texas. The fungus was found in multiple locations, including Huntsville State Park and Sam Houston National Forest, particularly on the Caney Creek Trail and Little Lake Creek Loop Trail. Observations were made from December to January, with some sightings also occurring in November. The mushrooms often grew in clusters or groups, and their caps were sometimes reddish-spotted. The fungus was typically found on pine logs, but one observation noted its presence on a mossy side of a log, which suggests it may be able to grow on other types of substrates as well.
