Distribution: It occurs in a variety of urban and suburban habitats including flower beds with wood chips and in lawns around the roots of trees. It can appear in summer, when few other species are fruiting, if sufficient moisture is available, such as from yard-watering.
Conservation Status: Not of concern
Gymnopus luxurians is an attractive mushroom with reddish brown caps that fade to pale brownish with age, cream-colored, close to crowded gills, and fleshy-fibrous, whitish to pale brownish stipes that have a twisted striate appearance, split lengthwise in age, and have cottony material over the lower surface and white strands attached to the base. Although solitary fruitbodies or small groups can occur, it usually forms large conspicuous clusters. G. luxurians is large and fleshy for a gymnopus and may reach 10 cm (4 in.) in diameter, the expanded caps becoming irregularly shaped and splitting from mutual pressure. Like G. erythropus and G. peronatus, it seemingly has become rather common in recent years.
