Agonimia flabelliformis is a species of corticolous (bark-dwelling) lichen in the family Verrucariaceae, first described in 2011 from specimens collected in the Czech Republic. It is distinguished from closely related species by its fan-shaped, finely branched growth form, appearing bright green when moist and pale brownish-green when dry. The species produces tiny, pear-shaped fruiting bodies containing clear, internally divided spores. Primarily found in shaded, humid forests, it occurs on tree bark, roots, rocks, and soil, often growing in association with mosses. A. flabelliformis has

Pseudolepraria is a fungal genus in the family Ramalinaceae. It comprises the single species Pseudolepraria stephaniana, a corticolous (bark-dwelling) leprose lichen found only in lowland tropical forests of Bolivia. First described as Lepraria stephaniana in 2010, the species was reclassified into its own genus in 2023 after molecular studies revealed its distinct phylogenetic position. The lichen is characterised by its thick, powdery, green-grey to creamy-white thallus lacking defined edges, and is notable for containing the rare compound 4-O-methylleprolomin. Unlike related Bolivian

Loxospora cristinae is a fungal species classified in 2018, found in a few European countries. It belongs to the division Ascomycota and the family Sarrameanaceae. It was first identified and described in the 19th century, but the species would not be correctly classified until almost two centuries later. Loxospora cristinae is a sterile crustose lichen, meaning it reproduces by a type of vegetative spore that has evolved specifically to produce morphological structures.

Chicitaea is a genus of lichen-forming fungi in the family Sarrameanaceae. Established in 2024, it comprises five species that grow as crusts on tree bark in forests across North America, Europe, Australia, China, and Thailand. The genus was separated from Loxospora based on molecular evidence and chemical differences, particularly the presence of 2'-O-methylperlatolic acid as the main secondary compound. The lichens appear in shades from pale grey-green to olive-grey and can reproduce through both vegetative structures (soredia or isidia) and, in one species, through sexual spore-producing
