Roccella is a genus of 23 species of lichens in the family Roccellaceae. The genus was circumscribed by Swiss botanist Augustin Pyramus de Candolle in 1805, with Roccella fuciformis as the type species.
Gallaicolichen is a fungal genus in the division Ascomycota. The relationship of this taxon to other taxa within the division is unknown, and it has not yet been placed with certainty into any class, order, or family. This is a monotypic genus, containing the single species Gallaicolichen pacificus, a foliicolous (leaf-dwelling) lichen.
Bacidina sorediata is a species of foliicolous (leaf-dwelling) lichen in the family Ramalinaceae. Found in the Seychelles, it was described as new to science in 2011. It is characterized by its distinct sorediate thallus and pale yellow to orange apothecia.
Phlyctis psoromica is a species of corticolous (bark-dwelling) crustose lichen in the family Phlyctidaceae. Native to New South Wales, Australia, it was described as new to science in 2011. This lichen is characterised by its whitish to pale blue-grey crustose thallus and distinctive secondary chemistry.
Enterographa serusiauxii is a species of leaf-dwelling lichen in the family Roccellaceae. It is found in Guadeloupe.
Tenuitholiascus is a fungal genus in the monotypic family Tenuitholiascaceae, itself in the order Strigulales. The genus contains a single species, Tenuitholiascus porinoides, a foliicolous (leaf-dwelling) lichen found in China.
Asterothyrium vezdae is a species of foliicolous (leaf-dwelling) lichen in the family Gomphillaceae. It is found in Bolivia, where it grows on the leaves of vascular plants in the Amazon rainforest. The lichen is distinguished from its closest relative, Asterothyrium octomerum, by the larger number of septa in its ascospores, and its and black apothecia.
Byssoloma fuscothallinum is a species of foliicolous (leaf-dwelling) lichen in the family Pilocarpaceae. Found in Colombia and French Guiana, it was formally described as a new species in 2006 by lichenologist Robert Lücking.
Enterographa incognita is a little-known species of crustose lichen in the family Roccellaceae. Found in Southeast Thailand, it is characterised by its sorediate features and its distinct ascomata and ascospores. This lichen, only known to occur in its type locality, thrives on large trunks in a mangrove environment.
Enterographa kinabaluensis is a species of corticolous (bark-dwelling) crustose lichen in the family Ramalinaceae. Found in coastal rainforests on the island of Borneo, it was described as a new species in 2020. Characterised by its white thallus, punctiform (dot-like) soralia and norstictic acid content, this lichen is readily recognisable when fertile.
Enterographa rotundata is a species of corticolous (bark-dwelling) crustose lichen in the family Roccellaceae. This species was discovered in Brazil, growing on the smooth bark of trees in the Brazilian Caatinga forest. It has round apothecia, a feature that sets it apart from most of its kind.
Fulvophyton is a genus of lichen-forming fungi in the family Roccellographaceae. It has 11 species. Fulvophyton is characterised by its crust-like thallus, which is often pale yellowish-brown in colour. This genus features a photobiont from the green algal genus Trentepohlia and exhibits a unique arrangement of reproductive structures.
Fulvophyton macrosporum is a species of corticolous (bark-dwelling), crustose lichen in the family Roccellographaceae. Found in the Seychelles, it was formally described as a new species in 2017 by lichenologists Damien Ertz and Paul Diederich. Its differentiation from the morphologically similar Sclerophyton madagascariense primarily hinges on its 10–14 septate (partitioned) ascospores and the existence of psoromic acid, while S. madagascariense typically contains 8–10-septate ascospores and features stictic acid. Fulvophyton macrosporum was first identified in Seychelles, in the Praslin National Park, situated southeast of Vallée de Mai. The species was discovered growing on trees between altitudes of 250–360 m (820–1,180 ft). Its species epithet macrosporum alludes to the relatively large ascospores that characterise the species.
Neosergipea septoconidiata is a species of corticolous (bark-dwelling) lichen in the family Roccellaceae. It is a unique species of lichen that grows on the bark of trees in the primary forests of Brazil with its bluish-grey thallus and bright orange pycnidia that have a fluffy hyphal surface.
Fissurina insidiosa is a species of corticolous (bark-dwelling), script lichen in the family Graphidaceae. Found in the Southern Hemisphere, it has been recorded from mainland Australia, New Zealand, the Pacific region, the Caribbean, and India.
Enterographa dokdoensis is a species of saxicolous (rock-dwelling), script lichen in the family Roccellaceae. It occurs in South Korea. The lichen has a thallus that can cover areas up to 5–10 cm in diameter, with a smooth to roughened texture and a green-grey to mauve colour.
Enterographa aldabrensis is a species of corticolous (bark-dwelling), crustose lichen in the family Roccellaceae. It is only known to occur in Aldabra in the Seychelles.
Fellhanera ivoriensis is a species of foliicolous (leaf-dwelling) lichen. First described in 2001, this species is distinguished from its relatives in the Fellhanera by its soredia-covered thallus and the characteristics of its apothecia. It is native to the Ivory Coast in West Africa.
The Pyrenotrichaceae are a small family of fungi in the order Chaetothyriales. It contains two genera, and a total of six species. The genus Pyrenothrix has two species of bark- or leaf-dwelling lichens, while Neophaeococcomyces has four species of saprobic fungi.
Tricharia nigriuncinata is a species of foliicolous (leaf-dwelling) lichen in the family Gomphillaceae. It is found in East Africa.
