Myxomphalia maura is a small, rare, and poorly known fungus. In St. Petersburg and Leningrad Oblast, it has been found growing on rotten wood, particularly on coniferous tree stumps and logs. Records from north-western Russia indicate that the species prefers shaded, humid environments with rich organic matter. Fruitbodies are typically small, with caps ranging from 0.5 to 2 cm in diameter, and stems up to 2 cm long, often with a distinctive blue-grey to grey-brown coloration. The species is considered rare in the region due to its specific habitat requirements and limited distribution.
