Eschatogonia
genus of fungi
Eschatogonia is a genus of lichen-forming fungi in the family Ramalinaceae. It has seven species. The genus was circumscribed by the Italian lichenologist Vittore Benedetto Antonio Trevisan de Saint-Léon in 1853.
Description
The genus Eschatogonia includes lichens with a squamulose thallus, meaning the body of the lichen is composed of small, scale-like lobes known as squamules. These squamules have a single layer of cortical (outer) tissue on both their upper and lower surfaces. The lichen's photobiont, or photosynthetic partner, is a green alga.
The apothecia (fruiting bodies) are sessile (directly attached to the surface without a stalk) and lack a thalline exciple, meaning they do not have a rim of thallus-derived tissue around them. The apothecia range in colour from flesh-toned (carneous) to reddish brown. Each ascus (spore-producing sac) within the apothecia typically contains eight spores. These spores are colourless and fusiform, meaning they are spindle-shaped, tapering at both ends.
Begin with the source’s own compact description: “Eschatogonia” is genus of fungi. The dossier treats that line as a proposition to test through Eschatogonia, genus and fungi, not as a finished interpretation.
Why this record matters
The phrase “genus of fungi” 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 Nov 6, 2024. The linked authority identifier is Q10489031. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1853.
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.
