Topeliopsis acutispora is a species of crustose lichen in the family Graphidaceae. [1] It is found in New South Wales and southern Queensland (Australia), where it grows on bryophytes (i.e., mosses or liverworts).
The lichen was formally described by lichenologist Klaus Kalb in 2001. The type specimen was collected from Cunninghams Gap in a cool temperate rainforest at an altitude of about 750 m (2,460 ft). The species epithet refers to the acute, or "pointy", shape of its spores. [2]
The lichen has a thin, whitish-grey to greenish-grey, effuse (spread-out) thallus. Its apothecia are more or less spherical to barrel-shaped, measuring 0.4–0.7 mm in diameter. The pale pink excipulum , initially closed, later opens via a ragged pore (ostiole). Ascospores typically number eight per ascus (sometimes only four are present), and are hyaline, halonate , and measure 90–130 by 9–12 μm. [2]
Topeliopsis decorticans appears to be morphologically identical to T. acutispora; the two species are distinguished by major differences in their ascospores, including shape, size, septation, and number per ascus. [3]
The Graphidaceae are a family of lichen-forming fungi in the order Ostropales. The family contains nearly a hundred genera and more than 2000 species. Although the family has a cosmopolitan distribution, most Graphidaceae species occur in tropical regions, and typically grow on bark.
Platygramme is a genus of lichenized fungi in the family Graphidaceae consisting of about 30 species. The genus was circumscribed by Antoine Laurent Apollinaire Fée in 1874.
Reimnitzia is a fungal genus in the family Graphidaceae. This is a monotypic genus, containing the single lichen species Reimnitzia santensis. Both the genus and species were described as new to science in 2001 by German lichenologist Klaus Kalb. The genus name honours Michael and Christine Reimnitz, friends of the author who assisted him with his lichen collections. The type species was originally named Theletrema santensis by American Edward Tuckerman, from specimens collected by Henry William Ravenel in South Carolina. The main characteristic of the lichen is the distinct epithecium formed by the densely interwoven upper parts of the paraphyses. Reimnitzia was originally classified in the Thelotremataceae, but that family has since been folded into the Graphidaceae.
Kalbionora is a lichen genus in the family Malmideaceae containing the single crustose species Kalbionora palaeotropica. This lichen occurs in coastal forests in Thailand, Vietnam, and northeastern Australia, where it grows on tree bark.
Allographa leptospora is a species of script lichen in the family Graphidaceae. The lichen was first formally described in 1921 by Finnish lichenologist Edvard August Vainio as Graphis leptospora. The type specimen was collected in 1904 by German botanist Carl Curt Hosseus on Doi Suthep, where it was found growing on tree bark. Hosseus sent this and other lichens collected from Thailand to Vainio for identification. Robert Lücking and Klaus Kalb transferred it to the genus Allographa in 2018. In 2016, the lichen was reported from the Sintra Mountains, Portugal, which was its first documented occurrence in Europe.
Acanthothecis kalbii is a species of script lichen in the family Graphidaceae. It was described as a new species in 2009 by Manuela Dal-Forno and Sionara Eliasaro. The type specimen was collected from Pontal do Sul in Pontal do Paraná, Brazil. The specific epithet honours German lichenologist Klaus Kalb.
Carbacanthographis acanthoamicta is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Papua New Guinea, it was formally described as a new species in 2022 by Shirley Cunha Feuerstein and Robert Lücking. The type specimen was collected from a primary montane forest in Myola at an altitude of 2,100 m (6,900 ft). It is only known to occur at the type locality. The lichen has an olive to yellowish brown thallus with a thin cortex and an underlying prothallus. Its ascospores number 8 per ascus, are hyaline and measure 17–20 by 8 μm; they have from 7 to seven transverse septa and from 0 to two longitudinal septa. Carbacanthographis acanthoamicta contains salazinic acid, a lichen product than can be detected using thin-layer chromatography. The specific epithet alludes to its similarity with Carbacanthographis amicta.
Carbacanthographis acanthoparaphysata is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Papua New Guinea, it was formally described as a new species in 2022 by Shirley Cunha Feuerstein and Robert Lücking. The type specimen was collected by André Aptroot from a primary montane forest in Myola at an altitude between 2,100 and 2,400 m. It is only known to occur at the type locality. The lichen has a whitish-grey to pale yellowish thallus lacking a cortex, but with a black prothallus. Its ascospores number eight per ascus, and are hyaline, measuring 17–20 by 8 μm; they have from 4 to 6 transverse septa and from 0 to 2 longitudinal septa. The specific epithet refers to the paraphyses, which give it an apically warty appearance. Carbacanthographis acanthoparaphysata contains protocetraric acid, a lichen product that can be detected using thin-layer chromatography.
Astrochapsa sipmanii is a little-known species of corticolous (bark-dwelling) lichen in the family Graphidaceae. It is found in Singapore.
Allographa uruguayensis is a species of corticolous (bark-dwelling), crustose lichen in the family Graphidaceae. Found in Uruguay, it was formally described as a new species in 2018 by lichenologist Robert Lücking. He had previously informally introduced the species as Graphis uruguayensis in a 2009 publication, but without a proper description. The type specimen was collected in 1968 by Henry Imshaug in Parque Franklin Delano Roosevelt, near Montevideo; here it was found in a planted grove containing Pinus and Eucalyptus. The lichen has a pale yellow-grey thallus, measuring 2–3 cm (0.8–1.2 in) across and 50–70 μm thick, which lacks a prothallus. The ascospores, which number 6 to 8 per ascus, are thick-walled, oblong with between 11 and 17 septa, and measure 45–70 by 6–8 μm. Allographa elongata is somewhat similar in morphology, but is distinguished by differences in the structure of the lirellae, and in ascospore width.
Pseudochapsa aptrootiana is a species of corticolous (bark-dwelling) in the family Graphidaceae. Found in Brazil, it was formally described as a new species in 2018 by Marcela Eugenia da Silva Cáceres, Thamires Almeida Pereira, and Robert Lücking. The type specimen was collected from Mata do Cipó at an elevation of 80–100 m (260–330 ft); here, in an Atlantic Rainforest remnant, it was found in the forest understory. It has a light grey thallus lacking a prothallus and a cortex. Its ascospores, which number eight per ascus, are oblong to spindle-shaped (fusiform) with between 11 and 15 septa and measure 30–35 by 7–8 μm. Lichen products that occur in Pseudochapsa aptrootiana include stictic and constictic acid as major or submajor metabolites, and minor to trace amounts of cryptostictic, hypostictic, and acetylhypoconstictic acids. The species epithet honours Dutch lichenologist André Aptroot, "for his invaluable contributions to tropical lichenology".

Ocellularia subudupiensis is a rare species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Singapore, it was formally described as a new species in 2015 by Gothamie Weerakoon and Robert Lücking. The type specimen was collected by the first author from a low-elevation primary forest in the Bukit Timah Nature Reserve. It is only known to occur at the type locality. The species epithet refers to its similarity with Ocellularia udupiensis. It differs from this lichen in its relatively rough thallus surface in addition to its secondary chemistry, as it contains three unidentified lichen products that are detectable using thin-layer chromatography.
Clandestinotrema is a genus of lichen-forming fungi in the family Graphidaceae. It has 17 species. They typically inhabit montane and cloud forest at higher elevations in the tropics.
