Sticta is a genus of lichens in the family Peltigeraceae. The genus has a widespread distribution, especially in tropical areas, and includes about 114 species. These lichens have a leafy appearance, and are colored brown or black. Sticta species with cyanobacteria as photobionts can fix nitrogen from the atmosphere, and due to their relative abundance and high turnover, they contribute appreciably to the rainforest ecosystem. They are commonly called spotted felt lichens.
Lepidostromatales is an order of fungi in the class Agaricomycetes. It is the only known order of basidiomycete fungi composed entirely of lichenized members. Morphologically, the fruiting bodies of all species are clavarioid. Six species are known, five of which were described within the span of 2007–2013. Due to its morphological similarity to the genus Multiclavula, its isolated phylogenetic position was not understood until quite recently. The photobionts that have been found in association with members of this group are not known to associate with any other types of lichenized fungi.
Ertzia is a monospecific genus in the family Lepidostromataceae. The sole species is Ertzia akagerae, a basidiolichen. The genus was circumscribed in 2014 by Brendan Hodkinson and Robert Lücking. Ertzia is distinguished from all other lichenized clavarioid fungi by having a microsquamulose thallus that forms contiguous glomerules with a cortex of jigsaw puzzle-shaped cells. Ertzia akagerae grows on soil in the African tropics.
Sulzbacheromyces is a genus of basidiolichens in the family Lepidostromataceae. The genus is distinguished from the other genera of Lepidostromataceae by having an entirely crustose thallus and from Multiclavula (Cantharellales) by having a chlorococcoid photobiont. The type species grows on soil in the neotropics.
Dictyonema hernandezii is a species of basidiolichen in the family Hygrophoraceae. Found in montane rainforests of Costa Rica and in Colombia, it was described as new to science in 2011. The specific epithet hernandezii honours Venezuelan lichenologist Jesús Hernández.
Cora hirsuta is a species of basidiolichen in the family Hygrophoraceae. Found in the páramo region near Bogotá at over 3,000 m (9,800 ft) elevation, it was described as new to science in 2011. The lichen, characterised by its distinctively hairy upper surface and smaller lobes, thrives in a variety of habitats, including soil, bryophytes, and as epiphytes on trees.
Sticta venosa is a species of terricolous (ground-dwelling), foliose lichen in the family Peltigeraceae. It is known only from Pichincha Province, Ecuador, and from Colombia. It was described as new to science in 2011.
Cora applanata is a species of basidiolichen in the family Hygrophoraceae. It was formally described as a new species in 2016 by Bibiana Moncada, Edier Soto-Medina, and Robert Lücking. The specific epithet refers to its applanate (flattened) thallus. The lichen is widely distributed in tropical montane areas of the northern Andes, where it grows on soil along open road banks and on land slides.
Cora gigantea is a species of basidiolichen in the family Hygrophoraceae. It was formally described as a new species in 2016 by Robert Lücking Bibiana Moncada, and Luis Fernando Coca. The specific epithet gigantea refers the large size of the thallus, and indirectly references David Leslie Hawksworth, who the authors describe as "a giant in mycology and lichenology". The lichen occurs in the mountainous cloud forests of Colombia at elevations around 2,500 m (8,200 ft), where it grows on the ground and between bryophyte and lichen mats.
Lobariella sipmanii is a species of foliose lichen in the family Peltigeraceae. It is found in high-altitude páramo in Cundinamarca, Colombia.
Sticta atroandensis is a species of foliose lichen in the family Peltigeraceae. It is found in the Colombian Andes.
Sticta viviana is a species of corticolous (bark-dwelling), foliose lichen in the family Peltigeraceae. It is found in Colombia, where it grows on the branches and twigs of shrubs and treelets in high-elevation páramo habitat.
Dictyonema obscuratum is a species of basidiolichen in the family Hygrophoraceae. Originally discovered in Brazil and later recorded in Bolivia and Colombia, its cryptic, olive-green thallus sets it apart from similar species like Dictyonema phyllophilum and D. schenckianum.
Lobariella reticulata is a species of foliose lichen in the family Peltigeraceae. It is found in Colombia.
Byssotrema is a monotypic fungal genus in the subfamily Graphidoideae of the family Graphidaceae. It contains the single species Byssotrema mirabile, a little-known corticolous (bark-dwelling), crustose lichen found only in Brazil.
Pseudocyphellaria hirsuta is a species of foliose lichen in the family Peltigeraceae. First described in 1835, it has undergone several taxonomic revisions over nearly two centuries. The lichen forms a flat, leaf-like structure (thallus) that can grow up to 27 cm in diameter, typically appearing grey or brown and covered in fine hairs. It is characterised by small pore-like structures called pseudocyphellae on its lower surface, which can be yellow or, less commonly, white. P. hirsuta grows mainly on trees in forested areas, particularly those dominated by southern beech (Nothofagus) species, but can also be found on rocks, soil, and stumps. The species is widely distributed in Argentina and Chile, from central regions to Tierra del Fuego, and has been observed in various forest types and elevations.
Saxiloba is a genus of lichen-forming fungi in the family Porinaceae. It comprises three species of saxicolous (rock-dwelling) placodioid lichens, known from disjunct locations in the Caribbean, Hawaii, and Brazil. The genus was circumscribed in 2020 to accommodate species with a distinctive placodioid thallus featuring unique surface patterns and internal crystal structures. Saxiloba lichens are characterised by their flattened, leaf-like thalli with marginal lobes, growing tightly appressed to rock surfaces. They have a complex internal structure, including large crystal clusters embedded within the photobiont layer, which may be an adaptation for light management in their typically shaded habitats.
Graphis flavopalmicola is a rare species of script lichen in the family Graphidaceae. It is found in South Korea. Graphis flavopalmicola is a lichen species known for its smooth to slightly wrinkled, pale greyish-white surface that glows pale yellow under ultraviolet light. Its fruiting bodies have black, exposed disc with edges that are entirely carbonised (blackened). The lichen produces small spores that are divided by several cross-walls.
Sulzbacheromyces tutunendo is a species of basidiolichen in the family Lepidostromataceae. It is found in Colombia.
Sulzbacheromyces caatingae is a species of basidiolichen in the family Lepidostromataceae. Discovered in 2012 in northeastern Brazil, it is characterised by its thin green crustose thallus and distinctive orange-pink, club-shaped reproductive structures. The species has a broad ecological amplitude, occurring across different vegetation types from the semi-arid Caatinga to humid Atlantic Forest fragments, where it grows on soil banks and termite nests near forest edges. As the type species of the genus Sulzbacheromyces, it represents a unique evolutionary lineage within the order Lepidostromatales and can be distinguished from similar-looking species by its undifferentiated thallus structure and association with green algae.
