Vittore Benedetto Antonio Trevisan de Saint-Léon

Italian botanist (1818-1897).

Vittore Benedetto Antonio Trevisan de Saint-Léon (5 June 1818, in Padua – 8 April 1897, in Milan) was an Italian botanist who specialized in cryptogamic flora. He edited the exsiccata Lichenotheca Veneta. During his career, he was a professor of natural history in Padua. In 1882, he was named president of the Accademia fisio-medica-statistica in Milan. In 1848, he circumscribed the genus Romanoa (family Euphorbiaceae) and in 1861, named the genus Speerschneidera (family Bacidiaceae). In 1888, he circumscribed the (Algae) genus Nocardia (family Nocardiaceae) that is now classed as bacteria. A

Heterodermia (Fringe Lichens) Trevis. 1868
fungi genus in the physciaceae family
Heterodermia is a genus of foliose lichens in the family Physciaceae. The genus has a widespread distribution, especially in tropical regions, and contains about 70 species. Heterodermia was historically confused with the related genus Anaptychia, but was distinguished in 1965 based on differences in spore structure and chemical composition. These lichens can be identified in the field using simple chemical spot tests that produce distinctive colour changes when applied to the thallus. The lichens in this genus are small- to medium-sized, usually pale grey in colour, comprising narrow lobes
Icmadophila (Peppermint Drop Lichens) Trevis. 1853
fungi genus in the icmadophilaceae family
Icmadophila is a genus of crustose lichen. The genus has a widespread distribution in the Northern Hemisphere and contains six species. The only species found in North America, Icmadophila ericetorum, has a mint green crustose thallus that is dotted with bright pink apothecial disks, and is sometimes colloquially referred to as "fairy puke". It aggressively grows over mosses on well-rotted wood and peat. It looks very distinctive, but may be confused with species of Dibaeis.
Stigmidium Trevis. 1860
fungi genus in the mycosphaerellaceae family
Stigmidium is a genus of lichenicolous (lichen-dwelling) fungi in the family Mycosphaerellaceae.

Hemithecium Trevis. 1853
fungi genus in the graphidaceae family
Hemithecium is a genus of lichen-forming fungi in the family Graphidaceae. These lichens form pale grey-white to yellow-olive crusts on tree bark and are characterized by straight to weakly curved fruiting bodies with charcoal-black walls that create sharp contrasts against the surface, along with distinctive spine-tipped filaments lining their interior chambers. The genus has a pantropical distribution, growing on shaded tree trunks and large branches in primary or lightly disturbed evergreen forests, where their marked sensitivity to canopy opening makes them practical indicators of intact,
Byssoloma (Fuzzy-rim Lichens) Trevis. 1853
fungi genus in the byssolomataceae family
Byssoloma is a genus of leaf-dwelling lichens in the family Ectolechiaceae.
Thalloloma Trevis. 1853
fungi genus in the graphidaceae family
Thalloloma is a genus of lichen-forming fungi in the family Graphidaceae. Established in 1853 by the Italian botanist Vittore Trevisan de Saint-Léon, the genus comprises 20 species distinguished by their narrow script-like slits immersed in a pale crusty surface, often with dark brown or occasionally crimson-dusted fruiting structures. Found throughout tropical regions from sea level to mountain forests above 3,000 metres, these bark-dwelling lichens are more tolerant of light and moisture variation than many related species, allowing them to colonise forest edges and moderately sun-exposed
Pyrenula mamillana (Big Pox) (Ach.) Trevis. 1860
fungi species in the pyrenulaceae family

Placocarpus Trevis. 1860

Eschatogonia Trevis. 1853
fungi genus in the ramalinaceae family
Eschatogonia is a genus of lichen-forming fungi in the family Ramalinaceae. It has seven species. The genus was circumscribed by the Italian lichenologist Vittore Benedetto Antonio Trevisan de Saint-Léon in 1853.
Blennothallia Trevis. 1853
fungi genus in the collemataceae family
Blennothallia is a genus of jelly lichens in the family Collemataceae. It has four species, which collectively have a cosmopolitan distribution.

Rostania Trevis. 1880
fungi genus in the collemataceae family
Rostania is a genus of lichen-forming fungi in the family Collemataceae. These lichens are primarily found on tree bark, occasionally on wood, with one species known to inhabit soil. The genus is characterized morphologically by having minute thalli made of hyphal tissue without a separate cortex, and the more or less cuboid-shaped ascospores.
Pyrenocarpon Trevis. 1855
fungi genus in the lichinaceae family
Pyrenocarpon is a fungal genus in the family Lichinaceae. It is monospecific, containing the single species Pyrenocarpon thelostomum, a lichen. This rare lichen is found only in shaded stream beds in parts of Britain, including Exmoor, the Pennines, and the Scottish Highlands. It was first described as a distinct genus in 1855 by the Italian lichenologist Vittore Trevisan based on its unique waxy fruiting structures. The species grows as a thin, reddish-brown crust on hard rocks that are kept constantly wet by flowing water.
Psoroma pholidotoides (Nyl.) Trevis. 1869
fungi species in the pannariaceae family

Placynthium asperellum (Lilliput Ink Lichen) (Ach.) Trevis. 1869
fungi species in the placynthiaceae family

Monerolechia Trevis. 1857
fungi genus in the caliciaceae family
Monerolechia is a genus of lichen-forming fungi in the family Caliciaceae. These lichens form crusty patches that break into small blocks or flakes, typically coloured chocolate to grey-brown, and produce black fruiting bodies for reproduction. Most species in this genus start life as parasites on other lichens before developing their own independent growth, which helps distinguish them from similar-looking lichen groups.
Kuettlingeria Trevis. 1857
fungi genus in the teloschistaceae family
Kuettlingeria is a genus of saxicolous (rock-dwelling), crustose lichens in the family Teloschistaceae. Species are characterized by a white or gray thallus and the presence of anthraquinones in the apothecial disc and true exciple, with the exception of Kuettlingeria diphyodes, which entirely lacks anthraquinones. First described by Italian botanist Trevisan in 1857, the genus includes 15 recognized species, although it is believed to be more diverse with additional unnamed species. These lichens are predominantly found in the Northern Hemisphere, particularly in the Mediterranean region,

fungi species in the trypetheliaceae family

Acolium Trevis. 1862
fungi genus in the caliciaceae family
Acolium is a genus of lichenized fungi in the family Caliciaceae. The genus has a widespread distribution and contains six species. These lichens are found on bark and wood, occasionally on rocks, or growing on other lichens. The genus was originally proposed as a subdivision of Calicium by Erik Acharius in 1808, and promoted to generic status by Samuel Frederick Gray in 1821.

Brigantiaea (Brick-spored Firedot Lichens) Trevis. 1853
fungi genus in the brigantiaeaceae family
Brigantiaea is a genus of lichen-forming fungi in the family Brigantiaeaceae. The genus was established in 1853 by the Italian botanist Vittore Trevisan and is named after Francesco Briganti, a professor at the University of Naples. These lichens are recognised by their bright yellow to orange fruiting bodies that stand out against their crusty, wart-textured surface.
Thalloloma anguinum (Mont.) Trevis. 1853

Speerschneidera (Speerschneidera Lichen) Trevis. 1861
fungi genus in the leprocaulaceae family
Speerschneidera is a single-species fungal genus that contains the saxicolous (rock-dwelling) crustose lichen Speerschneidera euploca. It is known from scattered localities in the south-central United States and Mexico, where it grows on shaded calcareous outcrops. The genus has had an unstable family placement: it was traditionally placed in Leprocaulaceae, but a 2025 multi-gene phylogenetic study recovered it in Catillariaceae and treated Leprocaulaceae as a synonym.
