Ampulloclitocybe clavipes, commonly known as the club-foot or club-footed clitocybe, is a species of gilled mushroom from Europe and North America. The grey-brown mushrooms have yellowish decurrent gills and a bulbous stalk, and are found in deciduous and conifer woodlands. While potentially edible, it resembles poisonous species and its consumption with alcohol can result in a disulfiram-like reaction.

Lichinales is the sole order of ascomycete fungi in the class Lichinomycetes. It contains three families: Gloeoheppiaceae (3 genera), Lichinaceae (43 genera), and Peltulaceae (1 genus). Most species are lichenized. Lichinales was proposed in 1986 by German lichenologists Aino Henssen and Burkhard Büdel. The class Lichinomycetes was created by Valérie Reeb, François Lutzoni and Claude Roux in 2004. A study published in late 2022 suggests that six classes of fungi, Candelariomycetes, Coniocybomycetes, Geoglossomycetes, Lichinomycetes, Sareomycetes, and Xylonomycetes, are all part of a clade

Lichenomphalia umbellifera, also known as the lichen agaric or the green-pea mushroom lichen, is a species of basidiolichen in the family Hygrophoraceae. It forms a symbiotic relationship with unicellular algae in the genus Coccomyxa.

Lichenomphalia is both a basidiolichen and an agaric genus. Most of the species have inconspicuous lichenized thalli that consist of scattered, small, loose, nearly microscopic green balls or foliose small flakes containing single-celled green algae in the genus Coccomyxa, all interconnected by a loose network of hyphae. The agaric fruit bodies themselves are nonlichenized and resemble other types of omphalinoid mushrooms. These agarics lack clamp connections and do not form hymenial cystidia. The basidiospores are hyaline, smooth, thin-walled, and nonamyloid. Most of the species were

The Lecanoromycetidae are a subclass of fungi in the class Lecanoromycetes. This subclass contains seven orders.

Ampulloclitocybe is a genus of three species of fungi with a widespread distribution.

The Acarosporales are an order of fungi in the class Lecanoromycetes. Phylogenetic analyses conducted using the sequences of both the protein-coding gene RPB2 as well as nuclear ribosomal genes place this order within the subclass Acarosporomycetidae. According to a recent (2020) survey of fungal classification, the Acarosporales contain two families: Acarosporaceae, with 11 genera and about 260 species, and Eigleraceae, with 1 genus and 2 species.

Arrhenia epichysium is a species of agaric fungus in the family Hygrophoraceae. The fruit body has small brown to dark gray caps measuring 1–3 cm (1⁄2–1+1⁄4 in) in diameter. The cap color changes to light gray to tan when it is dry. The gills are narrow and thin, placed together closely, and decurrently attached to the stipe, which can be up to 5 cm (2 in) long. The flesh is grayish and watery. The spores are smooth and ellipsoid, measuring 6–7.5 μm. The spore print is white. Outside of its genus, it can resemble the slightly larger Pseudoclitocybe cyathiformis. It can be found on dead wood

Lichenomphalia hudsoniana is a species of basidiolichen in the family Hygrophoraceae. It is widely distributed in alpine and arctic regions of the world, where it grows on moist soil amongst moss.

Loreleia is a genus of brightly colored agarics in the Hymenochaetales that have an omphalinoid morphology. They inhabit mosses and or liverworts on soil in temperate regions of the Northern Hemisphere. Phylogenetically related agarics are in the genera Contumyces, Gyroflexus, Rickenella, Cantharellopsis and Blasiphalia, as well as the stipitate-stereoid genera Muscinupta and Cotylidia and the clavaroid genus, Alloclavaria. However, the large number of DNA base-pair changes causes a long-branch to form in phylogenetic analyses depicted as cladograms. In the field, to the eye, Loreleia is most

Arrhenia chlorocyanea, commonly known as the verdigris navel, is a species of agaric fungus in the family Hygrophoraceae. Originally named as a species of Agaricus in 1885, and later classified as a member of Omphalina, the species was transferred to the genus Arrhenia in 2002. The blue mushroom's caps are under 2 centimetres (3⁄4 in) wide and the stems are 1–4 cm (3⁄8–1+5⁄8 in) tall. The spore print is white. Entoloma species such as E. incarnatofuscescens may appear somewhat similar, but have a pink spore print. It can be found in association with mosses in Europe and North America.

The Ostropomycetidae are a subclass of mostly lichen-forming fungi in the class Lecanoromycetes. It contains nine orders and 37 families. Arctomiaceae is the only family in the Ostropomycetidae that associates with cyanobacteria of the order Nostocales as its main photobiont partner.

Peltigera hydrothyria, commonly known as the waterfan, is a relatively rare aquatic lichen in the family Peltigeraceae, native to North America. It grows in cold, clean mountain streams, where it attaches to rocks and bedrock in shaded, riparian habitats. First described in 1856 as Hydrothyria venosa, it was initially placed in its own genus due to its distinctive gelatinous thallus and aquatic lifestyle. Molecular studies later demonstrated its affinity with the genus Peltigera, leading to its reclassification in 2000. The lichen forms small, blackish rosettes with ruffled margins and

Lichenomphalia velutina is a species of basidiolichen in the family Hygrophoraceae. It was first formally described in 1886 by the French mycologist Lucien Quélet, who classified it in the genus Omphalia. It was transferred to its current genus, Lichenomphalia, in 2002. Known primarily as having a European and North American distribution, the fungus was recorded from China (and Asia) for the first time in 2018. Chinese collections occur at elevations greater than 3,000 m (9,800 ft), while those in Europe tend to be at elevations under 1,500 m (4,900 ft). Lichenomphalia velutina also occurs in

Lichenomphalia chromacea is a species of basidiolichen in the family Hygrophoraceae. It is found in southern Australia. The yellow-orange fruiting bodies of the species are mushroom-like, with a cap width of typically less than 4 cm (1+1⁄2 in). The thallus of the lichen is a greenish, granular layer of fungal hyphae and algae on the soil around the base of the stipe.

Lichenomphalia aurantiaca is a species of agaricoid (mushroom-like) basidiolichen in the family Hygrophoraceae. It is found in Colombia. This unusual lichen produces both a minute granular thallus scattered over soil and tiny bright orange mushrooms with caps 10–15 mm across, gills, and stems that are the same vivid orange colour throughout. Originally described in 1987, it is classified as an endangered species due to its extremely limited distribution in Colombia's high-elevation páramo ecosystems.
