Rhaphidicyrtis
genus of fungi
Rhaphidicyrtis is a fungal genus of uncertain familial placement in the order Pyrenulales. It consists of the single species, Rhaphidicyrtis trichosporella, a bark-dwelling, crustose lichen that forms thin, pale patches on tree bark in humid deciduous woodlands. This small, inconspicuous lichen is characterised by tiny black reproductive structures scattered across its surface and distinctive microscopic features that set it apart from similar species. Originally described from Finnish collections in 1874, R. trichosporella has since been found in several European countries, including Sweden, Denmark, and the British Isles. The genus has been subject to taxonomic debate regarding its classification as a lichen, with recent observations confirming its symbiotic relationship with algae. Despite its widespread distribution, R. trichosporella is often rare within suitable habitats, suggesting specific environmental requirements that are not yet fully understood.
Taxonomy
The genus was cirucmscribed by Edvard August Vainio in 1921 to accommodate this species, which was originally described as Mycoporum trichosporellum by William Nylander in 1874. The type specimen was collected by Edvard Lang (later Edvard August Vainio).
The genus has been subject to some taxonomic uncertainty regarding its lichenisation status. While some authors have treated it as a non-lichenised fungus, others consider it to be lichenised.
This brief starts where responsible research should: with the source description of “Rhaphidicyrtis” as genus of fungi. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as genus of fungi. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated May 18, 2026. The linked authority identifier is Q10652166. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1874 and 1921.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. 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.
