Agrocybe praecox, commonly known as the spring agrocybe, early agrocybe, or spring fieldcap, is a species of fungus. According to modern analysis, it is one of a cluster of closely similar species, known as the A. praecox complex. It appears early in the year in woods, gardens, and fields in Eurasia, North Africa, and North America. It is of debatable culinary interest.

Cystoderma amianthinum, commonly called the common powdercap, saffron parasol, the saffron powder-cap, or the earthy powder-cap, is a small orange-ochre, or yellowish-brown, gilled mushroom. It grows in damp mossy grassland, in coniferous forest clearings, or on wooded heaths. It is probably the most common of the small genus Cystoderma. It is not recommended for consumption due to its resemblance to poisonous species.

Conocybe is a genus of mushrooms with Conocybe tenera as the type species and at least 243 other species. There are at least 50 different species in North America. Most have a long, thin fragile stipe and are delicate, growing in grasslands on dead moss, dead grass, sand dunes, decayed wood, and dung. Conocybe species generally prefer fertile soils in lawns and pastures and are found worldwide. Conocybe species are sometimes called dunce caps or cone heads due to their conical or bell-shaped caps. Former species of Conocybe that have a well-developed partial veil and/or lack lecythiform

Agrocybe is a genus of mushrooms in the family Strophariaceae (previously placed in the Bolbitiaceae). The genus has a widespread distribution, and contains about 100 species.

Omphalotus is a genus of basidiomycete mushroom, in the family Omphalotaceae, formally circumscribed by Victor Fayod in 1889. Members have the traditional cap and stem structure. They are saprobic, and fruit in clumps on the ground, adjacent to host trees. The best known and type species is the jack-o'-lantern mushroom (Omphalotus olearius). Species of Omphalotus have been mistaken for chanterelles. All Omphalotus species are presumed poisonous, causing gastrointestinal symptoms. Some Omphalotus species have bioluminescent properties.

Cystoderma carcharias, is a species of agaric in the fungal family Agaricaceae. It has a widespread distribution, and has been collected in coniferous forests and grasslands in Asia, Europe, North America, and the subantarctic islands. In the field, fruit bodies are characterized by a pink cap up to 6 cm (2.4 in) broad, a well-developed ring on the stem, and an unpleasant odour.

Cystoderma is a genus of fungi in the family Agaricaceae or Cystodermataceae. Its family position is in doubt and the family "Cystodermataceae" and tribe "Cystodermateae" have been proposed to include this group following recent molecular work. Previously Cystoderma comprised a wider range of species but in 2002 Harmaja separated some of them off into the new genus Cystodermella (for instance Cystoderma cinnabarinum, C. elegans and C. granulosum). The separation was made largely on the basis that the spores in the new genus were not at all amyloid. Those remaining in Cystoderma have weakly to

Amanita franchetii, also known as Franchet's amanita, is a species of fungus in the family Amanitaceae.

Agrocybe pediades, commonly known as the common fieldcap, common agrocybe, or hemispheric fieldcap, is a species of fungus. It can be found on grassland. It is potentially edible, but it could be confused with poisonous species, including one of the genus Hebeloma.

Boletopsis leucomelaena is a species of hydnoid fungus in the family Bankeraceae. The fungus is listed as a priority species in the United Kingdom Biodiversity Action Plan. B. leucomelaena is found in the Pacific Northwest region of North America, in Japan, and throughout Europe, although it is less common than the lookalike B. grisea.

Boletopsis is a genus of mycorrhizal fungi in the family Bankeraceae. The genus was circumscribed by Swiss mycologist Victor Fayod in 1889, with Boletopsis leucomelaena as the type species.

Hygrocybe intermedia is a species of agaric (gilled mushroom) in the family Hygrophoraceae. It has been given the recommended English name of fibrous waxcap. The species has a European distribution, occurring mainly in agriculturally unimproved grassland. Threats to its habitat have resulted in the species being assessed as globally "vulnerable" on the IUCN Red List of Threatened Species.

Tubaria conspersa, commonly known as the felted twiglet, is a species of mushroom in the genus Tubaria. It grows on duff and woody debris.

Pholiotina is a genus of small agaric fungi. It was circumscribed by Swiss mycologist Victor Fayod in 1889 for Conocybe-like species with partial veils. The genus has since been expanded to include species lacking partial veils.

Delicatula is a genus of fungi in the family Tricholomataceae. It was first described by Swiss mycologist Victor Fayod in 1889. The genus contains two widely distributed species.

Armillaria socialis is a species of fungus in the family Physalacriaceae. It is a plant pathogen. Originally described by Augustin Pyramus de Candolle in 1815, it was transferred to Armillaria by Victor Fayod in 1889. It is found in Asia, Europe, and North America.

Schinzinia is a fungal genus in the family Agaricaceae. It is a monotypic genus, containing the single species Schinzinia pustulosa Fayod. The genus and the species were circumscribed by Victor Fayod in Ann. Sci. Nat. Bot. ser.7, vol.9 on page 365 in 1889. The genus name of Schinzinia is in honour of Hans Schinz (1858–1941), who was a Swiss explorer and botanist and was a native of Zürich.
