Description:

Slo.: noviasta skorjederka - Habitat: mixed broadleaved and conifer wood, locally flat terrain, calcareous ground; in shade; partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 6-8 deg C, elevation 835 m (2.750 feet), alpine phytogeographical region. Substratum: decayed dead branch of Fagus sylvatica lying on ground. Comment: Biscogniauxia nummularia is a common fungus in beech woods of the Upper Soa River region. It can be recognized by more or less round, but many times also confluent and irregular shape, (almost) black spots on rotting trunks and fallen branches of Fagus sylvatica. Spots are flat, not cushion like. Ostioles are rather small. Ref.: (1) J. Breitenbach, F. Kraenzlin, Eds., Fungi of Switzerland, Vol.1. Verlag Mykologia (1984), p 270. (2) R.
