Scutula is a genus of lichenicolous fungi in the family Ramalinaceae.
The Ramalinaceae are a family of lichenized fungi in the order Lecanorales. The family name is synonymous with the name Bacidiaceae. Species of this family have a widespread distribution.
Bacidina is a genus of lichens in the family Ramalinaceae. It was circumscribed by Czech lichenologist Antonín Vězda in 1990, with Bacidina phacodes assigned as the type species. Vězda included 11 species in Bacidina, which was originally classified in the Lecideaceae. These species had previously been placed in genus Bacidia.
Bacidia is a genus of lichen-forming fungi in the family Ramalinaceae. The genus was circumscribed by Giuseppe De Notaris in 1846. Species in the genus are crust-like lichens with stemless apothecia; they have green algae (chloroccoid) as photobionts. Their asci have 8 colorless, cylindrical to acicular, multiseptate spores, with curved and thread-like conidia.
Adelolecia is a genus of crustose lichens in the family Lecanoraceae. The genus was circumscribed by Hannes Hertel and Josef Hafellner in 1984. The genus was formerly classified in the family Ramalinaceae, but molecular phylogenetic analysis showed it to belong to the Lecanoraceae.
Aciculopsora is a genus of lichens in the family Ramalinaceae. It was circumscribed by lichenologists André Aptroot and Marie Trest in 2006.
Myelorrhiza is a genus of two Australian species of lichenized fungi in the family Ramalinaceae. It was circumscribed in 1986 by Australian lichenologists Doug Verdon and John A. Elix. Myelorrhiza was originally classified in the family Cladoniaceae until Kistenich and colleagues, using molecular phylogenetic analysis, showed that it is more appropriately placed with the Ramalinaceae.
Crustospathula is a genus of five species of crustose lichens in the family Malmideaceae. They are characterized by their stalked and sometimes branched cartilaginous soredia and Bacidia-like apothecia.
Rolfidium is a genus of lichenized fungi in the family Ramalinaceae.
Phyllopsora is a genus of lichenized fungi in the family Ramalinaceae. It was circumscribed by Swiss botanist Johannes Müller Argoviensis in 1894.
Krogia is a genus of corticolous lichens in the family Ramalinaceae. It occurs in tropical humid forests and rainforests. The genus was circumscribed by Norwegian lichenologist Einar Timdal in 2002, with Krogia coralloides assigned as the type species.
Toniniopsis is a genus of crustose and squamulose lichens in the family Ramalinaceae. The genus was circumscribed by Swiss lichenologist Eduard Frey in 1926, with Toniniopsis obscura designated the type and only species. The genus name of Toniniopsis is in honour of Carlo Tonini (1803–1877), who was an Italian chemist and botanist (Lichenology), who worked in Verona and was a member and President of the Academy of Agriculture. As a result of molecular phylogenetic studies, several species, formerly classified in genus Bacidia, have been transferred to Toniniopsis.
Hildur Krog was a Norwegian botanist.
Malmideaceae is a family of crustose and corticolous lichens in the order Lecanorales. It contains eight genera and about 70 species.
Bibbya is a genus of fruticose lichens in the family Ramalinaceae.
Biatora oxneri is a species of corticolous (bark-dwelling) lichen in the family Ramalinaceae. It is found in the Russian Far East and in South Korea.
Phyllopsora amazonica is a species of corticolous (bark-dwelling), crustose lichen in the family Ramalinaceae. It is found in the Amazon rainforest of Brazil.
Phyllopsora neotinica is a species of corticolous (bark-dwelling), squamulose (scaley) lichen in the family Ramalinaceae. Found in North, Central, and South America, it was formally described as a new species in 2019 by lichenologists Sonja Kistenich and Einar Timdal. It is similar to Phyllopsora chodatinica, but unlike that species, it contains argopsin and often zeorin, but it lacks chodatin. The species epithet neotinica is a contraction of "neotropical" and Phyllopsora chodatinica.
Crustospathula amazonica is a species of corticolous (bark-dwelling), crustose lichen in the family Ramalinaceae. Found in South America, it was formally described as a new species in 2014 by lichenologists André Aptroot, Marcela Cáceres, and Einar Timdal. The type specimen was collected by the first two authors from the Parque Natural Municipal de Porto Velho, where it was found growing on the smooth bark of a tree in a primary rainforest. It also occurs in French Guiana and Peru, and tends to grow in association with lichens of the genus Porina and with thelotremoid members of the family Graphidaceae. The lichen has a film-like, green thallus consisting of fine, aggregated granules; no prothallus is present. Soredia are whitish, roughly spherical, and occur at the tips of cartilagous stalks up to 3 mm tall.
Physcidia striata is a species of corticolous (bark-dwelling), microfoliose lichen in the family Ramalinaceae. Found in South America, it was formally described as a new species in 2014 by lichenologists André Aptroot, Marcela Cáceres, and Einar Timdal. The type specimen was collected by the first two authors from the Estação Ecológica de Cuniã (Rondônia), where it was found growing on the smooth bark of a tree in a primary rainforest. It also occurs in Peru. The thallus of the lichen is a loose mat of squamules (scales) without a hypothallus. Its lobes are smooth, flat, branched, and greyish-green, measuring 2–7 mm long by 0.5–1.5 mm wide. The species epithet striata refers to the faint longitudinal striations that are present on the lobe undersides. Isidia occur on the thallus surface; they are the same colour as the thallus, with dimensions of 0.3–0.7 mm long by 0.1–0.2 mm wide. When they are abraded, it reveals the whitish colour of the underlying medulla. The lichen contains divaricatic acid, a lichen product that is revealed with the use of thin-layer chromatography.
