The Adelococcaceae are a family of fungi in the order Verrucariales. Species are mostly found in north temperate regions, and are biotrophic or necrotrophic on lichens. The family was proposed by mycologist Dagmar Triebel in 1993.
Sarcopyrenia is a genus of lichenicolous (lichen-dwelling) fungi. It has 11 species. It is the only genus in Sarcopyreniaceae, a family in the order Verrucariales. Sarcopyrenia was circumscribed by Finnish lichenologist William Nylander in 1858, with Sarcopyrenia gibba assigned as the type species. Sarcopyreniaceae is one of the few families composed entirely of lichenicolous fungi.
Leptochidium is a genus of lichen-forming fungi in the family Massalongiaceae. It has two species:
Bellemerea is a genus of saxicolous (rock-dwelling) crustose lichens in the family Lecideaceae. The genus was circumscribed in 1984 by Josef Hafellner and Claude Roux, with B. alpina as the type species. The generic name honours French lichenologist André Henri Bellemère (1927–2014).
Hypocenomyce is a genus of lichen-forming fungi in the family Ophioparmaceae. Species in the genus grow on bark and on wood, especially on burned tree stumps and trunks in coniferous forest. Hypocenomyce lichens are widely distributed in the northern hemisphere.
Melaspilea is a genus of lichen-forming and lichenicolous fungi in the family Melaspileaceae. The genus was circumscribed by Finnish lichenologist William Nylander in 1857.
Hydropunctaria is a genus of saxicolous (rock-dwelling), crustose lichens in the family Verrucariaceae. The genus includes both aquatic and amphibious species, with members that colonise either marine or freshwater habitats. The type species, Hydropunctaria maura, was formerly classified in the large genus Verrucaria. It is a widely distributed species common to littoral zones. Including the type species, five Hydropunctaria lichens are considered marine species: H. adriatica, H. amphibia, H. aractina, H. orae, and H. oceanica.
Philippe Clerc is a Swiss lichenologist. A Festschrift was dedicated to him in 2020, on the occasion of his retirement from the Conservatory and Botanical Garden of the City of Geneva, where he worked from 1993 to 2020. Clerc is an authority on the beard lichens, and has had nearly 100 publications on this and other topics, such as the lichen flora of Switzerland.
Maurice Léopold Joseph Bouly de Lesdain was a French botanist and lichenologist.
Heteroplacidium zamenhofianum is a species of lichenicolous (lichen-eating) lichen in the family Verrucariaceae. As a juvenile, it is parasitic on some members of the lichen genus Staurothele, but later becomes independent and develops a brown, crustose thallus. Characteristic features of the lichen include its dark brown, somewhat squamulous thallus and relatively small ascospores. It is widely distributed in Europe and North America.
Pseudosagedia is a genus of corticolous (bark-dwelling) lichens in the family Trichotheliaceae. It was first circumscribed as a section of genus Arthopyrenia by Swiss botanist Johannes Müller Argoviensis in 1862. Maurice Choisy elevated it to distinct generic status in 1949. Pseudosagedia was little used until, in 1995, Josef Hafellner and Klaus Kalb resurrected the genus to contain members of the Porina nitidula species group with the perithecial pigment called Pseudosagedia-violet and lacking setae.
Verrucula is a genus of lichenicolous (lichen-dwelling) lichens in the family Verrucariaceae. Species in the genus are parasitic on saxicolous (rock-dwelling), crustose lichens, including Xanthoria elegans as well as lichens from genus Caloplaca that contain chemical substances called anthraquinones.
Ferdinand Joseph Georges Alexandre Clauzade was a French botanist and lichenologist. His specialty was the lichen flora of France and the Mediterranean region.
Claude Roux is a French lichenologist, mycologist and Esperantist. He has co-authored books about the identification of lichens written in Esperanto.
Pseudopyrenidium is a genus of lichenicolous (lichen-dwelling) fungi in the family Adelococcaceae. The genus was circumscribed in 2010 by Père Navarro-Rosinés, Mikhail Zhurbenko, and Claude Roux. It has two species:
Schaereria fuscocinerea is a species of saxicolous (rock-dwelling), crustose lichen in the family Schaereriaceae. It was first formally described in 1852 by Finnish lichenologist William Nylander, as Lecidea fusco-cinerea. Georges Clauzade and Claude Roux transferred it to the genus Schaereria in 1985. The species has a cosmopolitan distribution and is found in both northern and southern hemispheres, where it grows on hard siliceous rocks, often in arctic and mountainous areas. Similar species include Lambiella gyrizans and L. mullensis, which can be distinguished from Schaereria fuscocinerea by microscopic and chemical characteristics.
Squamulea subsoluta is a species of saxicolous (rock-dwelling), squamulose lichen in the family Teloschistaceae. It was first formally described by Finnish lichenologist William Nylander in 1873, who named it as a variety of Lecanora murorum. He promoted it to species status three years later, as Lecanora subsoluta. Ulf Arup and colleagues transferred the taxon to the genus Squamulea in 2013, following a molecular phylogenetics-based restructuring of the family Teloschistaceae.
Stigmidium cerinae is a species of lichenicolous (lichen-dwelling) fungus in the family Mycosphaerellaceae. It was formally described as a new species in 1994 by mycologists Claude Roux and Dagmar Triebel. The type specimen was collected in Austria from the apothecia of the muscicolous (moss-dwelling) species Caloplaca stillicidiorum. It infects lichens in the genus Caloplaca, and more generally, members of the family Teloschistaceae. Infection by the fungus results in bleaching of the host hymenium.
Hydropunctaria amphibia is a species of saxicolous (rock-dwelling), crustose lichen in the family Verrucariaceae. One of several marine lichens in the genus Hydropunctaria, is widely distributed across Europe, extending from Norway to the Mediterranean and the Iberian coasts, and has a nearly ubiquitous presence along the Catalan coast of Spain. In North America, it is found along the Atlantic Coast from Nova Scotia to the Boston Harbor islands, where its presence in low-pollution areas indicates its potential as a bioindicator for marine lichen community health, and on the west coast in British Columbia, particularly in the Gwaii Haanas's upper littoral fringe. The black, crust-like thallus grows on seashore rocks – both siliceous rocks and limestone – in the lower supralittoral zone, an area also known as the splash zone. Originally described more than two centuries ago as a species of Verrucaria, Hydropunctaria amphibia sets itself apart from other species in Hydropunctaria through the distinct shape of the perithecium apex, which is either flat-topped or scalloped, in contrast to the typically rounded or immersed apex seen in its relatives.
