Topeliopsis is a genus of lichen-forming fungi in the family Graphidaceae.
Taxonomy
The genus Topeliopsis was established in 2000 by the lichenologists Gintaras Kantvilas and Antonín Vězda as part of their studies on the lichen family Thelotremataceae in Tasmania. The genus name, which contains the Greek "-opsis", alludes to its superficial resemblance to the lichen genus Topelia.
Topeliopsis was created to accommodate those members of Thelotremataceae that possess certain distinctive characteristics:
- {{lichengloss|sessile}} or somewhat immersed apothecia (the disc-shaped reproductive structures)
- {{lichengloss|perithecioid}} growth form (flask-shaped structures that open by a small pore)
- {{lichengloss|cupular}} excipulum (a cup-like structure surrounding the reproductive tissue)
- deeply {{lichengloss|urceolate}} disc (a deeply concave, pitcher-shaped reproductive surface)
- markedly thickened young asci (the sac-like structures containing spores)
- large, thin-walled, {{lichengloss|muriform}} ascospores that turn reddish in iodine
The genus is closely related to both Chroodiscus and Pseudoramonia, but differs from Chroodiscus by having a concave disc rather than a plane one, and by possessing a cupular (cup-shaped) rather than ring-like {{lichengloss|excipulum}}. While Pseudoramonia shares the perithecioid apothecia with a cupular excipulum, it differs by having {{lichengloss|stipitate}} (stalked) apothecia and transversely septate spores that do not react with iodine.
When first circumscribed, Topeliopsis included three species:
- T. muscicola (the type species) – endemic to Tasmania and New Zealand
- T. rugosa – endemic to Tasmania
- T. toensbargii – found in the Pacific Northwest of North America
