Wagner, H. -G. & Lumbsch, H. T. 2014. Coppinsia minutissima new to Brandenburg. — Herzogia 27: 189–191.
Regarded as growing in metal-enriched habitats, Coppinsia minutissima is reported for the state of Brandenburg for the very first time. The substrate of the new collection was not influenced by heavy metals. This and additional records previously published show that the species is not restricted to metal-enriched soil but has a broader ecological amplitude.
