Heterodermia leucomela  forme ramicole des arbres à feuilles persistantes.

    Differs from the Heterodermia leucomela type by its small size, its habitat: twigs of branch ends of evergreen trees in humid oceanic woodlands: Abies, Pseudotsuga,... It may be common, and probably is understated due to the observation conditions, mostly restricted to fallen or cut trees or branches.*
