Leucodecton is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed in 1860 by Swiss lichenologist Abramo Bartolommeo Massalongo, with Leucodecton compunctum assigned as the type species.
Chapsa is a genus of lichens in the family Graphidaceae. The genus was described by Italian lichenologist Abramo Bartolommeo Massalongo in 1860.
Psilolechia is a genus of four species of crustose lichens. It is the only member of Psilolechiaceae, a family that was created in 2014 to contain this genus.
Mazosia is a genus of lichen-forming fungi in the family Roccellaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1854.
Bagliettoa is a genus of lichen-forming fungi in the family Verrucariaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1853. Bagliettoa species are endolithic, growing between the grains of solid rock.
Placidium is a genus of crustose to squamulose to almost foliose lichens. The genus is in the family Verrucariaceae. Most members grow on soil, but some grow on rock (saxicolous). The fruiting bodies are perithecia, flask-like structures immersed in the lichen body (thallus) with only the top opening visible, dotting the thallus. Lichen spot tests are all negative. Members of the genus lack rhizines, but otherwise resemble members of the genus Clavascidium.
Parmotrema is a genus of lichen belonging to the family Parmeliaceae. It is a large genus, containing an estimated 300 species, with a centre of diversity in subtropical regions of South America and the Pacific Islands.
Psorotichia is a genus of lichen-forming fungi in the family Lichinaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1855, with Psorotichia murorum assigned as the type species.
Thyrea is a genus of lichen-forming fungi in the family Lichinaceae. It contains four species that have been accepted by Species Fungorum. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1856, with Thyrea plectospora assigned as the type species.
Physma is a genus of cyanolichens in the family Pannariaceae. It has five species. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1854, with Physma boryanum assigned as the type species.
Ropalospora is a genus of lichen-forming fungi, and the sole member of the monogeneric family Ropalosporaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1860. The family was proposed by Josef Hafellner in 1984.
The Caliciaceae are a family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. Although the family has had its classification changed several times throughout its taxonomic history, the use of modern molecular phylogenetic methods have helped to establish its current placement in the order Caliciales. Caliciaceae contains 36 genera and about 600 species. The largest genus is Buellia, with around 300 species; there are more than a dozen genera that contain only a single species.
Carlo Luigi Spegazzini, in Spanish Carlos Luis Spegazzini, was an Italian-born Argentinian botanist and mycologist.
Abramo Bartolommeo Massalongo was an Italian paleobotanist and lichenologist. He was born in Tregnago in the Province of Verona and took a great interest in botany as a young man. Massalongo joined the faculty of medicine at the University of Padua in 1844. Along with Gustav Wilhelm Körber, he founded the "Italian-Silesian" school of lichenology. He was the husband of Maria Colognato and the father of hepaticologist Caro Benigno Massalongo. He also worked in the scientific field of herpetology. In 1859 his Catalogo dei rettili delle province venete was published in Venice.
Haematomma is a genus of crustose lichens established by Abramo Bartolommeo Massalongo in 1852. It is the sole genus in the Haematommataceae, a family circumscribed by Josef Hafellner in 1984. Commonly called bloodstain lichens, the species assigned to this genus are widely distributed in tropical and temperate areas.
Dacampia is a genus of fungi in the family Dacampiaceae. It contains 15 species. The genus was circumscribed in 1853 by Italian lichenologist Abramo Bartolommeo Massalongo, with Dacampia hookeri assigned as the type species. The genus name honours Italian naturalist Benedetto de Dacampo (1787–1851).
Loxospora is a genus of lichen-forming fungi in the family Sarrameanaceae. It has 13 species. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1852, with Loxospora elatina assigned as the type species. This crustose lichen was originally named Lecanora elatina by Erik Acharius in 1810.
Phacopsis thallicola is a species of lichenicolous (lichen-dwelling) fungus in the family Parmeliaceae. It was first formally described as a new species in 1852 by Italian botanist Abramo Bartolommeo Massalongo, as Lecidea thallicola. The type specimen, collected from the province of Treviso in Italy, was growing on the foliose lichen Parmelia caperata. Dagmar Triebel and Gerhard Walter Rambold transferred the taxon to the genus Phacopsis in 1988. The known generic hosts of Phacopsis thallicola are all in the Parmeliaceae: Parmotrema, Cetrelia, Flavopunctelia, and Hypotrachyna.
Celotheliaceae is a family of fungi in the monotypic order Phaeomoniellales. The family was proposed in 2008 by Robert Lücking, André Aptroot, and Harrie Sipman, while the order was circumscribed in 2015. It is sister to the clade that includes the orders Verrucariales and Chaetothyriales. Molecular clock calculations suggest that the order originated when gymnosperm diversification occurred.
