Collybia nuda, commonly known as the blewit, wood blewit or blue foot and previously described as Lepista nuda and Clitocybe nuda, is a species of fungi. Described by Pierre Bulliard in 1790, it was also known as Tricholoma nudum for many years. It is morphologically similar and related to the field blewit, Collybia personata; both mushrooms were reassigned to the genus Collybia in 2023. The species is native to Europe and North America. It is found in both coniferous and deciduous woodlands. It has been cultivated in Britain, the Netherlands and France. It is a widely consumed edible

Laccaria amethystina, commonly known as the amethyst deceiver, or amethyst laccaria, is a small brightly colored mushroom. Because its bright amethyst coloration fades with age and weathering, it becomes difficult to identify, hence the common name "deceiver". This common name is shared with its close relation L. laccata, which also fades and weathers. Recently, some of the other species in the genus have been given the common name of "deceiver". It is found mainly in Northern temperate zones, in deciduous and coniferous forests, though it is reported to occur in tropical Central and South

Laccaria laccata, commonly known as the deceiver, lackluster laccaria, or waxy laccaria, is a species of fungus. It is a small but highly variable mushroom (hence 'deceiver'), and can look quite washed out, colorless and drab, but when younger it often assumes red, pinkish brown, and orange tones. It has white spores. Found throughout North America and Europe, the species is often considered by mushroom collectors to be a 'mushroom weed' because of its abundance and plain stature. The cap is edible.

Cortinarius rubellus, commonly known as the deadly webcap, is a species of fungus in the family Cortinariaceae, native to high-latitude temperate to subalpine forests of Eurasia and North America. Within the genus it belongs to a group known as the Orellani, all of which are highly toxic. Eating them results in kidney failure, which is often irreversible. The mushroom is generally tan to brown all over, with a conical to convex cap 2.5 to 8 centimetres (1 to 3+1⁄4 in) in diameter, adnate gills and a 5.5 to 11 cm (2+1⁄4 to 4+1⁄4 in) tall stipe.

Collybia personata (also recognised as Lepista personata, Lepista saeva, Clitocybe saeva and Tricholoma personatum, and commonly known as the field blewit and blue-leg) is a species of edible fungus commonly found growing in grassy areas across Europe.

Peziza domiciliana, commonly known as the domicile cup fungus, is a species of fungus in the genus Peziza, family Pezizaceae. Described by English mycologist Mordecai Cubitt Cooke, the fungus grows on rotten wood, drywall/plasterboard, and plaster in homes, damp cellars, and basements. It is known from Eurasia, North America, and Antarctica.

Peniophora is a genus of fungi which are plant pathogens. Members of the genus belong to the class Agaricomycetes, order Russulales, and family Peniophoraceae. The genus is widespread, and contains 62 species. The species of Peniophora are resupinate, or crust-like, and are described as corticioid. A number of its members are parasitised by other fungi. For example, Tremella mesenterica is a parasite to several species of Peniophora.

Peniophora quercina is a species of wood-decay fungus in the family Peniophoraceae. It produces fruit bodies that vary in appearance depending on whether they are wet or dry. The wet fruit bodies are waxy and lilac, and attached strongly to the wood on which they grow. When dry, the edges curl up and reveal the dark underside, while the surface becomes crusty and pink. P. quercina is the type species of the genus Peniophora, with the species being reclassified as a member of the genus upon the latter's creation by Mordecai Cubitt Cooke. P. quercina is found primarily in Europe, where it can

Marasmius cohaerens is a species of gilled mushroom which is fairly common in European woods.

Puccinia purpurea is a fungal species and plant pathogen that causes rust on sorghum. It is found in temperate places worldwide, excluding colder parts such as Russia and Canada. The pathogen was discovered in 1876 by Cooke, on the leaves of Sorghum vulgare in Maharashtra, India. P. purpurea is also native to eastern Australia, except Queensland. Where, it is considered a pest.

Didymiaceae is a family of plasmodial slime molds in the order Physarales.

Puccinia lagenophorae is a rust fungus which infects plants in the family Asteraceae, particularly Senecio squalidus and Senecio vulgaris. It is native to Australia, and was first found in Europe in 1961. It produces aecia and telia on its hosts.

Byssosphaeria is a genus of fungi in the family Melanommataceae.

Ramularia ulmariae is a fungal species described by Cooke in 1876. Ramularia ulmariae belongs to the genus Ramularia and the family Mycosphaerellaceae. No subspecies are listed in the Catalogue of Life. This fungus is a pathogen of meadowsweet (Filipendula ulmaria) that causes purple spots on the plant's leaves and is most evident in summer. It produces translucent, cylindrical conidia with up to two septa. Ramularia ulmariae has been reported from Europe and also the western coast of North America. However its presence is probably under-recorded.

Peniophora cinerea is a species of fungus in the family Peniophoraceae. It is a plant pathogen infecting black walnut (Juglans nigra). It was first described as a species of Corticium by Christiaan Hendrik Persoon in 1797. Mordecai Cubitt Cooke transferred it to Peniophora in 1879. It is found in Asia and North America.

Metraria is a genus of two species of fungi in the family Agaricaceae.

Gymnosporangium clavipes is a plant pathogen, a fungus that causes cedar-quince rust. Similar to Gymnosporangium juniperi-virginianae and Gymnosporangium globosum, the fungus infects a wide range of Rosaceae, such as apple, hawthorn and quince trees, and also requires an evergreen host such as eastern red cedar or a number of other juniper species to complete its life cycle.

Dichomera is a genus of fungi in the family Botryosphaeriaceae. There are 39 species.

The Coniochaeta are a genus of pleomorphic yeasts of the order Coniochaetales and are pathogens of trees. Some species have also been found to form endophytic associations within plants in which they live inside plant tissues but do not actually harm the organism. They can take the form of pink to brown colonies, hyphae, conidiophores or sclerotia. In 2013, the Lecythophora were merged with the Coniochaeta, following suggestions by Ziauddin Khan et al.

Botrytis elliptica is a necrotrophic fungal pathogen which infects species of plants in the Lilium genus, causing the disease commonly known as Lily Gray Mold. The symptoms of Lily Gray Mold include the appearance of water-soaked spots on leaves which appear white and increase in darkness with age, ranging from gray to brown. These spots may cover the entire leaf, complemented with a gray webbing, containing the fungal spores. The leaves will appear wilted and branches may die back. In addition to leaves, petals, stems, and buds may be infected, and this gray webbing will eventually cover the

Berggrenia is a genus of fungi in the Ascomycota phylum. The relationship of this taxon to other taxa within the phylum is unknown (incertae sedis), and it has not yet been placed with certainty into any class, order, or family.
