Bogoriella is a genus of crustose lichens in the family Trypetheliaceae. The genus was circumscribed by Alexander Zahlbruckner in 1928, with Bogoriella subpersicina assigned as the type species. It was later shown that Bogoriella was an older name for Mycomicrothelia, and so all of the species that were in that genus needed to be transferred to Bogoriella.
Architrypethelium is a genus of lichen-forming fungi in the family Trypetheliaceae.
Astrothelium is a large genus of corticolous (bark-dwelling) lichens in the family Trypetheliaceae. The genus is characterized by a corticate thallus and diverse ascomata structures, which can be simple, aggregated, or forming pseudostromata. Astrothelium is also notable for the carbonized walls of its ascomata, the so-called textura intricata arrangement of cells in these walls, and various forms of distoseptate, transparent spores.
Polymeridium is a genus of lichen-forming fungi in the family Trypetheliaceae. Species in the genus are corticolous (bark-dwelling) and typically occur in tropical areas.
Pseudopyrenula is a genus of lichen-forming fungi in the family Trypetheliaceae.
Viridothelium is a genus of lichen-forming fungi in the family Trypetheliaceae. It has 11 species. The genus was circumscribed by Robert Lücking Matthew Nelsen, and André Aptroot in 2016, with Viridothelium virens assigned as the type species. Lichens in this genus were previously assigned to genus Trypethelium, as part of the Trypethelium virens clade.
Bathelium is a genus of lichen-forming fungi in the family Trypetheliaceae.
Astrothelium vulcanum is a species of corticolous (bark-dwelling) lichen in the family Trypetheliaceae. Found in Guyana, it was formally described as a new species in 2016 by André Aptroot. The type specimen was collected from the Kuyuwini Landing (Rupununi) at an elevation of 200 m (660 ft); here, in a savannah forest, it was found growing on the smooth bark of trees. The lichen has a smooth, somewhat shiny thallus surrounded by a thin black prothallus, and covering areas up to 25 cm (10 in) in diameter. Its ascospores are spindle-shaped (fusiform) with rounded edges, with three septa and dimensions of 20–25 by 6.5–7.5 μm. Astrothelium vulcanum contains lichexanthone, a lichen product that causes the thallus to fluoresce when lit with a long-wavelength UV light.
Constrictolumina is a genus of lichen-forming fungi in the family Trypetheliaceae. The genus was circumscribed in 2016 by Robert Lücking, Matthew Nelsen, and André Aptroot, with Constrictolumina cinchonae assigned as the type species. The genus contains tropical species, formerly placed in genus Arthopyrenia, with a unique hamathecium.
Astrothelium ecuadorense is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. Found in Ecuador, it was formally described as a new species in 2016 by Dutch lichenologist André Aptroot. The type specimen was collected by Harrie Sipman in the Estacion Cientifico San Francisco in the South Ecuadorian Andes ; there, it was found in a mountainous rainforest growing on smooth tree bark. The lichen has a smooth and shiny, pale yellowish-green thallus with a cortex but lacking a prothallus, covering areas of up to 10 cm (4 in) in diameter. No lichen products were detected in the collected specimens. The main characteristics of the lichen distinguishing it from others in Astrothelium are the lack of pseudocyphellae on the thallus, and the solitary, exposed, black ascomata. It is also one of the few Astrothelium species with only two spores in its asci.
Astrothelium lucidostromum is a species of corticolous (bark-dwelling) lichen in the family Trypetheliaceae. Found in Guyana, it was formally described as a new species in 2016 by Dutch lichenologist André Aptroot. The type specimen was collected by Harrie Sipman about 45 km (28 mi) south of Aishalton at an altitude of 230 m (750 ft); there, it was found in a savanna forest growing on smooth tree bark. The lichen has a smooth and somewhat shiny, pale yellowish-grey thallus with a cortex but lacking a prothallus, which covers areas of up to 7 cm (2.8 in) in diameter. The presence of the lichen does not induce the formation of galls in the host plant. The pseudostromata contains lichexanthone, a lichen product that causes that structure to fluoresce when lit with a long-wavelength UV light. The main characteristics of the lichen distinguishing it from others in Astrothelium are the UV+ pseudostroma; the fused ascomata; and the immersed pseudostroma that have a white cover. Astrothelium eustomuralis is a smiliar species, but in that species, lichexanthone only occurs in the ostiole, not the entire pseudostroma.
Astrothelium perspersum is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. Found in Gabon, it was formally described as a new species in 2016 by lichenologists André Aptroot and Damien Ertz. It is one of the few Trypetheliaceae species known only from Africa. The type specimen was collected by the second author between the villages of Massaha and Batouala ; there, it was found in a rainforest growing on smooth tree bark. The lichen has a smooth and somewhat shiny, pale greenish-grey thallus with a cortex and a thin black prothallus line. It covers areas of up to 4 cm (1.6 in) in diameter. The presence of the lichen does not induce the formation of galls in the host plant. No lichen products were detected from collected specimens using thin-layer chromatography. The combination of characteristics of the lichen that distinguish it from others in Astrothelium are the dimensions of its ascospores ; and the arrangement and form of its ascomata—from irregular groups to pseudostromatic, with the pseudostromata erumpent, and white. Astrothelium perspersum is somewhat similar to A. scoria, but has larger ascospores than that species.
Astrothelium pseudoferrugineum is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. Found in Indonesia, it was formally described as a new species in 2016 by Dutch lichenologist André Aptroot. The type specimen was collected in 1937 by Pieter Groenhart on Jombang (Java); there, it was found in a disturbed rainforest growing on smooth tree bark. The lichen has a smooth and somewhat shiny to glossy, bright orange thallus with a cortex but without a prothallus. The orange crust is about 0.1 mm thick and covers areas of up to 3 cm (1.2 in) in diameter. The use of thin-layer chromatography shows the lichen contains an orange anthraquinone, possibly parietin. The main characteristics of the lichen that distinguish it from others in Astrothelium are its immersed to erumpent, whitish pseudostromata. It is named for its similarity to Astrothelium ferrugineum, from which it differs in its glossier thallus and larger ascospores.
Astrothelium carassense is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. Found in Brazil, it was formally described as a new species in 2016 by Robert Lücking, Matthew Nelsen, and Marcelo Marcelli. The type specimen was collected by the first author from the Santuário do Caraça, at an altitude between 1,300 and 1,400 m. The lichen has an uneven to bumpy, pale olive-yellow thallus that covers areas of up to 10 cm (4 in) in diameter. The pseudostromata are covered with an orange anthraquinone compound. The species epithet carassense refers to the type locality. The characteristics of the lichen that distinguish it from others in genus Astrothelium are its pseudostromatic ascomata, which are erumpent, with an orange cover; and the dimensions and form of its ascospores, which are muriform and measure 100–170 by 30–40 μm. Astrothelium purpurascens is somewhat similar in appearance to A. carassense, but it lacks pseudostromatic pigment and has slightly smaller ascospores.
Astrothelium cryptolucens is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. Found in Panama, it was formally described as a new species in 2016 by Robert Lücking, Matthew Nelsen, and Noris Salazar Allen. The type specimen was collected by the first author from the Altos de Campana National Park at an altitude of 500–600 m (1,600–2,000 ft); there, in a submontane rainforest, it was found growing on the bark of roadside trees. The lichen has an uneven to coarsely bumpy, olive-yellow thallus that covers areas of up to 10 cm (4 in) in diameter. The species epithet cryptolucens makes reference both to the habit of the immersed perithecia and the presence of lichexanthone. The characteristics of the lichen that distinguish it from others in genus Astrothelium are the finely and densely cracked pseudostromata that dominate the thallus, with dispersed thallus bumps; and the hardly visible ascomata that are completely immersed in pseudostromata. A. cryptolucens is somewhat similar to Astrothelium carrascoense, but that species does not have an inspersed hamathecium.
Astrothelium fijiense is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. Found in Fiji, it was formally described as a new species in 2016 by Robert Lücking, Khwanruan Naksuwankul, and Helge Thorsten Lumbsch. The type specimen was collected from Nakoba Levu at an altitude of 750 m (2,460 ft); there, it was found growing on bark on a steep slope in a secondary forest. The lichen has a smooth to uneven, light olive-yellow thallus that covers areas of up to 5 cm (2 in) in diameter. Both the thallus and the pseudostromata contain lichexanthone, a lichen product that causes these structures to fluoresce a yellow colour when lit with a long-wavelength UV light. The species epithet fijiense refers to the type locality. The characteristics of the lichen that distinguish it from others in genus Astrothelium are the distinctly pseudostromatic ascomata, and the presence of lichexanthone on the pseudostromata. Astrothelium cinereorosellum is somewhat similar, but that species has slightly longer ascospores and does not have lichexanthone on the pseudostromata.
Astrothelium laevithallinum is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. Found in Brazil, it was formally described as a new species in 2016 by Robert Lücking, Matthew Nelsen, and Marcelo Marcelli. The type specimen was collected by the first author from the Santuário do Caraça at an altitude between 1,300 and 1,400 m ; there, in Atlantic Forest, it was found in a forest remnant near a waterfall. The lichen has a smooth to uneven, green thallus that covers areas of up to 5 cm (2 in) in diameter. The species epithet laevithallinum alludes to the contrast between its smooth thallus and the bullate thallus of its phylogenetically distinct but close relative, Astrothelium endochryseum. The characteristic of the lichen that distinguishes A. laevithallinum from others in genus Astrothelium is the smooth thallus.
Astrothelium leucosessile is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. Found in Panama, it was formally described as a new species in 2016 by Robert Lücking, Matthew Nelsen, and André Aptroot. The type specimen was collected by the first author from the Altos de Campana National Park at an altitude between 500 and 600 m ; there, in a submontane forest, it was found growing on the bark of roadside trees. The lichen has a smooth to uneven, light olive-grey thallus that covers areas of up to 5 cm (2 in), and has streaks of yellowish-white pruina. Both the thallus and the pseudostromata contain lichexanthone, which cause these structures to fluoresce yellow when lit with a long-wavelength UV light. The species epithet leucosessile refers to the whitish colour and sessile habit of the pseudostromata. The characteristics of the lichen that distinguish Astrothelium leucosessile from others in genus Astrothelium are its well delimited, whitish pseudostromata, which are prominent to sessile. Astrothelium phlyctaena is somewhat similar in appearance, but that species does not have conspicuous, sessile pseudostromata.
Astrothelium macrostomoides is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. Found in Brazil, it was formally described as a new species in 2016 by Robert Lücking, Matthew Nelsen, Michel Navarro Benatti. The type specimen was collected by the first author from the Santuário do Caraça at an altitude between 1,300 to 1,400 m ; there, in the Atlantic Forest biome, it was found growing on bark in a gallery forest along a river. The lichen has an uneven to coarsely bullate, olive-green thallus that covers areas of up to 7 cm (2.8 in). Ascomata are in the form of perithecia, which are arranged in aggregated groups of 5–10 in pseudostromata. The pseudostromata contain lichexanthone, which is a lichen product that causes these structures to fluoresce yellow when lit with a long-wavelength UV light. The species epithet macrostomoides alludes to the similarity of the lichen with Astrothelium macrostomum, from which it differs by having larger ascospores. The characteristics of the lichen that distinguish it from others in genus Astrothelium are the diffusely pseudostromatic ascomata with erumpent pseudostromata, covered by thallus, each with a single group of fused ascomata; and the dimensions and form of the ascospores, which measure 80–110 by 17–25 μm, and have from five to seven septa.
Dictyomeridium is a genus of corticolous (bark-dwelling), crustose lichens in the family Trypetheliaceae. It has eight species.
