The Lecanoraceae are a family of lichenized fungi in the order Lecanorales. Species of this family have a widespread distribution.
Scoliciosporaceae is a family of lichen-forming fungi in the order Lecanorales. It contains two genera, the monotypic Umushamyces, and the type genus Scoliciosporum. The family was circumscribed by lichenologist Josef Hafellner in 1984.
Adelolecia is a genus of crustose lichens in the family Lecanoraceae. The genus was circumscribed by Hannes Hertel and Josef Hafellner in 1984. The genus was formerly classified in the family Ramalinaceae, but molecular phylogenetic analysis showed it to belong to the Lecanoraceae.
The Lichinaceae are a family of ascomycete fungi. Most species are lichenized with cyanobacteria, and have a distribution largely in temperate regions.
Carbonea is a genus of fungi in the family Lecanoraceae. Most of the species grow on lichens. The genus is widespread, and contains 20 species. Carbonea was originally circumscribed as a subgenus of Lecidea in 1967 before it was promoted to generic status in 1983.
Cladidium is a genus of two species of lichen in the family Lecanoraceae. Cladidium was circumscribed by Josef Hafellner in 1984 with C. thamnitis assigned as the type species. C. bolanderi was added to the genus in 1989.
The Lecideaceae are a family of lichens in the order Lecideales. It contains about 30 genera about roughly 250 species. A major distinguishing characteristic of the family is the lecanoroid form of the fruiting bodies: typically circular, dark, and without a thalline margin. Most species in the family are lichenised with green algae, although a few species, scattered amongst several genera, are lichenicolous–they live on other lichens. Lecideaceae lichens tend to grow on rocks, wood, and soil. The largest genus in the family, Lecidea, was once a loosely circumscribed wastebasket taxon containing hundreds of morphologically similar species with generally crustose thalli, photobiont-free apothecial margins and translucent, single-celled ascospores. The overall taxonomy and classification within the family has been made more accurate with recent molecular phylogenetics studies.
Clauzadea is a genus of lichenized fungi in the family Lecideaceae. The genus contains four species found in Europe. Clauzadea was circumscribed in 1984 by lichenologists Josef Hafellner and André Bellemère.
Poeltiaria is a genus of lichen-forming fungi in the family Lecideaceae. It was circumscribed in 1984 by lichenologist Hannes Hertel, with Poeltiaria turgescens assigned as the type species.
Xenolecia is a genus of saxicolous (rock-dwelling) and crustose lichens in the family Lecideaceae. It has two species: X. cataractarum, and the type species, X. spadicomma. The genus was circumscribed by German lichenologist Hannes Hertel in 1987 to contain the type, a lichen known at that time only from the type locality on Wellington Island, Chile. Its range has since been expanded to include the Falkland Islands and northern Patagonia. X. cataractarum, found in Campbell Island, New Zealand was added to the genus in 2017.
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.
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.
Josef Hafellner is an Austrian mycologist and lichenologist. He was awarded the Acharius Medal in 2016 for his lifetime contributions to lichenology. Before his retirement, he was a professor at the Karl-Franzens-Universität in Graz. Hafellner started developing an interest in lichens while he was a student at this institution, studying under Josef Poelt. He earned a master's degree in 1975 and a PhD in 1978, defending a doctoral thesis about the genus Karschia. In 2003, Hafellner received his habilitation. By this time, he had studied with French lichenologist André Bellemère (1927–2014) at Saint-Cloud, where he learned techniques of transmission electron microscopy and how their application in studying asci could be used in lichen systematics. His 1984 work Studien in Richtung einer natürlicheren Gliederung der Sammelfamilien Lecanoraceae und Lecideaceae has been described as "probably the single most influential publication in lichen systematics in the latter half of the 20th century".
Catillaria is a genus of crustose lichens in the family Catillariaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1852. It is the type genus of Catillariaceae, which was circumscribed by Austrian lichenologist Josef Hafellner in 1984.
Eiglera is a genus of crustose lichens belonging to the family Eigleraceae. Eiglera species are found in Europe and Northern America.
Xylographaceae is a family of lichen-forming fungi in the order Baeomycetales. It contains four genera and 25 species.
Lambiella is a genus of lichen-forming fungi in the family Xylographaceae. The genus was circumscribed by German botanist Hannes Hertel in 1984, with Lambiella psephota assigned as the type species.
Placolecis is a genus of lichen-forming fungi in the family Catillariaceae. It has four species of saxicolous (rock-dwelling) and crustose lichens. The genus was circumscribed by Italian botanist Vittore Benedetto Antonio Trevisan de Saint-Léon in 1857. He did not assign a type species for the genus. Josef Hafellner designated a lectotype for Placolecis balanina in 1984, but subsequently, this taxon was folded into P. opaca.
Harpidiaceae is a small family of lichen-forming fungi, containing two genera and five species. It is of uncertain classification in the Pezizomycotina.
Sarrameanaceae is a family of lichen-forming fungi in the monotypic order Sarrameanales. It contains two genera, Loxospora, and Sarrameana, the type genus. The family was circumscribed by Josef Hafellner in 1984. The order Sarrameanales was proposed by Brendan Hodkinson and James Lendemer in 2011, as they had noted that previously published large-scale molecular phylogenetic studies had shown that the group of species contained in the family Sarrameanaceae were distinct and separate from the clade containing all of the other orders of the Ostropomycetidae. However, the name Sarrameanales was not validly published according to the rules of botanical nomenclature, because it was not accompanied by a suitable description. Despite this, the order continues to be used in lichenological literature.
