The author discusses the distribution of Pleurotus serotinus in Czechoslovakia based on confirmed localities. This relatively rare species has been collected only in a few places in the country and is listed and mapped. In Czechoslovakia, it is usually found on hardwoods, often in mountainous beech forests, even where beech has been replaced by spruce monocultures. It is also found on alder, and more rarely on hornbeam, ash, oak, and birch. It prefers acidic soils and humid, colder regions, especially in southern Bohemia. The species is proposed to be placed in the genus Sarcomyxa.
