Galerina marginata, known colloquially as funeral bell, deadly skullcap, autumn skullcap or deadly galerina, is a species of extremely poisonous mushroom-forming fungus in the family Hymenogastraceae of the order Agaricales. Before 2001, the species G. autumnalis, G. oregonensis, G. unicolor, and G. venenata were thought to be distinct from G. marginata due to differences in habitat and the viscidity of their caps, but phylogenetic analysis showed that they are all the same species. The fruit bodies of the mushroom have brown to yellow-brown caps that fade in color when drying. The gills are

The Marasmiaceae are a family of fungi in the order Agaricales. Basidiocarps (fruit bodies) are most frequently agarics (gilled mushrooms), but occasionally cyphelloid (in the genus Cellypha). According to a 2008 estimate, the family contained 54 genera and 1590 species, but molecular research, based on cladistic analysis of DNA sequences, has led to a more restricted family concept, so that the Marasmiaceae included just 13 genera, and some 1205 species. It was reduced further down in 2020, to 10 genera and about 700 species.

The Pleurotaceae are a family of small to medium-sized mushrooms which have white spores. The family contains 13 genera over 412 species. Members of Pleurotaceae can be mistaken for members of Marasmiaceae. Perhaps the best known member is the oyster mushroom, Pleurotus ostreatus. Many species in the genera Pleurotus and Hohenbuehelia are nematophagous, that is, they derive nutrition by consuming nematodes. This is made possible by hyphae that may have adhesive knobs that attach to passing nematodes and secrete nematotoxic compounds.

Sarcomyxa serotina is a species of fungus in the family Sarcomyxaceae. Its recommended English name in the UK is olive oysterling. In North America it is known as late fall oyster or late oyster mushroom.

Xeromphalina campanella is a species of mushroom. Its common names include the golden trumpet and the bell Omphalina. It is a cold-tolerant species found throughout North America and Eurasia.

Conocybe tenera, commonly known as the brown dunce cap or common cone head, is a widely distributed member of the genus Conocybe, for which it serves as the type species.

The Hygrophoropsidaceae are a family of mushrooms that are gilled in appearance but lie within the Boletales. The family contains 18 species within two genera: Leucogyrophana and Hygrophoropsis, with the best-known member being the "false chanterelle", Hygrophoropsis aurantiaca. Hygrophoropsidaceae was circumscribed by French mycologist Robert Kühner in 1980, with Hygrophoropsis as the type genus. Unlike most members of the Boletales, Hygrophoropsidaceae species are saprophytic wood-rotting fungi that cause brown rot in their hosts. The genera Austropaxillus and Tapinella, once placed in this

Xeromphalina is a genus of fungi in the family Mycenaceae. The genus has a widespread distribution, and contains about 30 species.

Hygrocybe reidii, commonly known as the honey waxcap, is a mushroom of the waxcap genus Hygrocybe.

Galerina hypnorum is a species of agaric fungus in the family Hymenogastraceae. The species has a hygrophanous cap measuring 4-15 mm in diameter, initially conical and becoming broadly convex with age. When moist, the cap is honey-yellow to ochraceous tawny, fading to buff or tawny brown as it dries. The surface is striate when wet and glabrous to faintly fibrillose.

Lentinellus ursinus is a species of fungus belonging to the family Auriscalpiaceae. The caps are 2–10 centimetres (1–4 in) wide, often separated into lobes. They are brown in the center, fading to white at the margin. The spore print is white. It may require microscopy to distinguish from L. angustifolius. Lookalikes from other genera include Pleurotus ostreatus. It can be found in North America from October–March on the West Coast and July–October elsewhere. Like all species in its genus, it is inedible due to its bitterness.

Xeromphalina cauticinalis is a species of agaric fungus in the family Mycenaceae. Originally described in 1838 by Elias Fries as Marasmius cauticinalis, it was transferred to the genus Xeromphalina by Robert Kühner and René Maire in 1934. The fruit bodies have convex yellowish caps measuring 0.5–2.5 cm (1⁄4–1 in) in diameter supported by a tough yellow-brown to dark brown stipe that is 2.5–8 cm (1–3+1⁄8 in) long and 0.5–2.5 millimetres (1⁄32–3⁄32 in) thick. The pale yellow gills have a decurrent attachment to the stipe and are somewhat distantly spaced. The spore print is white, while

Galerina graminea, known as the turf bell is a species of mushroom in the genus Galerina. Unlike many Galerina mushrooms, it can survive in moss-free grass. It was known for many years as 'Galerina laevis', proposed by Christiaan Hendrik Persoon. Galerina means helmet-like, while graminea means "of grass". It is not known whether it is poisonous or not; however, it is suspected to be.

Fayodia is a genus of fungi in the family Tricholomataceae. It was first described by Robert Kühner in Bull. Bi-Mens. Soc. Linn. Lyon Vol.9 on page 68 in 1930, and the specific epithet honors the Swiss mycologist Victor Fayod (1860–1900). The widespread genus contains 10 species, mostly in the northern temperate regions.

Conocybe rickenii is a mushroom from the genus Conocybe. Its edibility is disputed, and it has the appearance of a typical little brown mushroom with a small, conical cap, and long, thin stem. In colour, it is generally a cream-brown, lighter on the stem, and it has a thin layer of flesh with no distinct smell or taste. It is a coprophilous fungus, feeding off dung and it is most common on very rich soil or growing directly from dung. It can be found in Europe, Australia and Pacific islands.

Lentinellus vulpinus is a species of fungus belonging to the family Auriscalpiaceae. It has a cosmopolitan distribution. Like all species in its genus, it is inedible due to its bitterness.
