Phylloblastia bielczykiae is a little-known species of foliicolous (leaf-dwelling) lichen in the family Verrucariaceae. Found in Bolivia, it was formally described as a new species in 2008. The lichen has an indistinct, crustose thallus with a mealy (farinose) to grainy (granulose) texture, and a pale yellowish-green to olivaceous colour. It is somewhat similar to Phylloblastia inconspicua, but has smaller ascospores.

Lepraria achariana is a species of leprose lichen in the family Stereocaulaceae. It occurs at high elevations in Bolivia.

Trichothelium subargenteum is a species of foliicolous (leaf-dwelling) crustose lichen in the family Porinaceae. Found in Bolivia, it was scientifically described in 2008 by the lichenologists Adam Flakus and Robert Lücking. The specific epithet subargenteum refers to its similarity to another species, T. argenteum, which has been found in Costa Rica and Argentina.

Porina boliviana is a species of foliicolous (leaf-dwelling) crustose lichen in the family Porinaceae. It was formally described as a new species in 2008 by the lichenologists Adam Flakus and Robert Lücking. They named it after the country where it was discovered, Bolivia. Flakus collected the type specimen from Nuevos Reyes village in the José Ballivián Province (Beni Department), where he found it growing on palm tree leaves in a lowland Amazon forest.

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.

Zhurbenkoa is a genus of lichenicolous (lichen-dwelling) fungi in the family Malmideaceae. It comprises three species. Zhurbenkoa fungi grow on the thalli of species in the widespread lichen genus Cladonia. The genus was established in 2019 and named after the Russian scientist Mikhail Zhurbenko for his work studying fungi that live on lichens. These tiny parasites produce minute dark spots less than half a millimetre wide on their host lichens, and the three species can be distinguished by differences in their ascospore shapes and sizes.

Tapellaria intermedia is a little-known species of foliicolous (leaf-dwelling) crustose lichen in the family Ectolechiaceae. It occurs in Bolivia.

Remototrachyna sipmaniana is a species of saxicolous (rock-dwelling), foliose lichen in the family Parmeliaceae. It is only known to occur in Bolivia, where it grows on boulders in Yungas mountain cloud forests.

Spirographa ciliata is a species of lichenicolous fungus in the family Spirographaceae. It was first formally described by Klaus Kalb in 1993 as Cornutispora ciliata. Adam Grzegorz Flakus, Javier Etayo, and Jolanta Miądlikowska transferred it to genus Spirographa in 2019.

Lepraria glaucosorediata is a species of leprose lichen in the family Stereocaulaceae. It was formally described in 2009 from specimens collected in the Bolivian Andes at high elevation. The lichen is characterised by its thick, powdery crust with a distinctive bluish-grey tint and unusual soredial structure. It grows on rocks and mosses in humid, shaded locations within high-elevation puna grassland.

Lecanora microloba is a species of crustose and areolate lichen in the family Lecanoraceae, formally described in 2010. This lichen is characterized by its distinctive flat areoles that either remain isolated or form small rosette-like structures, with minute lobed margins that give the species its name. Currently known only from two localities in the Polish Tatra Mountains and more recently reported from Ukraine, it grows specifically on mylonitized granite rock intrusions in the highest vegetation belt of the Carpathians. The lichen contains several chemical compounds including gyrophoric

Fuscidea multispora is a species of foliicolous (leaf-dwelling), crustose lichen in the family Fuscideaceae. Found in Bolivia, it is known to occur only in a single high-altitude locality in a national park, where it grows on the leaves of coniferous trees from the genus Podocarpus.

Astrothelium chulumanense is a little-known species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. Found in the Yungas montane forest of Bolivia, it was formally described as a new species in 2023. It is characterized by pseudostromata not differing in colour from the thallus, perithecia immersed for the most part in the thallus with the upper part elevated above and covered with orange pigment, apical and fused ostioles, the absence of lichexanthone, a clear hamathecium, eight-spored asci, and large, muriform ascospores with a thickened median septum.

Acarospora dissecta is a species of saxicolous (rock-dwelling), crustose lichen in the family Acarosporaceae. It grows on volcanic rock in high-altitude regions of the Andes. Its distinguishing features include a crust-like formation of dispersed areoles, a unique combination of organic acids, and a distinctive fissuring pattern. This lichen thrives in the semi-desert, high Andean areas, and currently, its known distribution is limited to specific areas in Bolivia.

Trypethelium xanthoplatystomum is a species of corticolous (bark-dwelling) crustose lichen in the family Trypetheliaceae. This tropical lichen forms yellowish to greyish-green crusty patches on tree bark and is distinguished by its bright orange-yellow, raised, wart-like structures that contain clusters of small fruiting bodies. It can be identified by its yellow fluorescence under ultraviolet light, caused by the presence of lichexanthone in the lichen's tissues. It was described as new to science in 2016 by Adam Flakus and André Aptroot from material collected in lowland Bolivia.

Trypethelium astroideum is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. It was described as new to science by Adam Flakus and André Aptroot from material collected in lowland Bolivia.
