Ramboldia
genus of lichenized fungi
Ramboldia is a genus of lichen-forming fungi in the family Ramboldiaceae. The genus was established in 1994 to accommodate several Australasian lichens that form crusts on wood, bark, and rock surfaces, and it was named in honour of the German mycologist Gerhard Rambold. These lichens are characterised by their small, disc-shaped fruiting bodies and their chemical composition, which includes β-orcinol derivatives and sometimes anthraquinones, though they lack the distinctive crimson reaction found in the related genus Pyrrhospora. The genus contains about 40 species found worldwide, ranging in colour from pale grey to nearly black.
Taxonomy
Ramboldia was erected in 1994, when Gintaras Kantvilas and John Elix showed that several Australasian Lecidea-like wood-inhabiting lichens did not fit any recognised genus of the Lecanoraceae and therefore warranted a new taxon. In their protologue they noted morphological affinities with Pyrrhospora but emphasised the complete absence of the KOH-reactive crimson or purple anthraquinones that characterise that genus, thus justifying separation. The authors placed five species in Ramboldia at inception—lignicolous R. stuartii (designated type) and R. subnexa, corticolous R. brunneocarpa, and the rock-dwelling pair R. petraeoides and R. plicatula. The genus name honours the German mycologist Gerhard Walter Rambold for his contributions to the study of Australasian lecideoid lichens.
The genus was emended in 2008 by the inclusion of Pyrrhospora species containing the anthraquinone compound russulone in their apothecia and having a prosoplectenchymatous exciple. The family Ramboldiaceae was erected in 2014 to contain the genus.
The public source identifies “Ramboldia” as genus of lichenized fungi. This brief keeps that definition visible, then builds a research path around Ramboldia, genus and lichenized.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Ramboldia”, the useful work is to connect “genus of lichenized fungi” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q7289258. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1994, 2008 and 2014.
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.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
