Anzia colpodes
species of fungus

Anzia colpodes, commonly known as the black foam lichen, is a species of corticolous (bark-dwelling), foliose lichen in the large family Parmeliaceae. It occurs in eastern North America.
Taxonomy
The lichen was first formally described as a new species by the Swedish lichenologist Erik Acharius in 1799. He classified it in the eponymous genus Lichen, which was standard at the time. In 1803 he transferred it to the genus Parmelia. Ernst Stizenberger transferred it to the genus Anzia in 1862.
Begin with the source’s own compact description: “Anzia colpodes” is species of fungus. The dossier treats that line as a proposition to test through Anzia, colpodes and species, not as a finished interpretation.
Why this record matters
The phrase “species of fungus” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 13, 2025. The linked authority identifier is Q17390795. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1799, 1803 and 1862.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
