Mycena is a large genus of small saprotrophic mushrooms that are rarely more than a few centimeters in width. The name Mycena comes from the Ancient Greek μύκηςmykes, meaning "fungus". Species in the genus Mycena are commonly known as bonnets.
Roridomyces roridus, commonly known as the dripping bonnet or the slippery mycena, is a species of agaric fungus in the family Mycenaceae. It is whitish or dirty yellow in color, with a broad convex cap 5–15 mm (0.2–0.6 in) in diameter. The stipe is covered with a thick, slippery slime layer. This species can be bioluminescent, and is one of the several causative species of foxfire.
Mycena interrupta is a species of mushroom. It has a Gondwanan distribution pattern, being found in Australia, New Zealand, New Caledonia and Chile. In Australia, it is found in Victoria, Tasmania, New South Wales, South Australia, and Queensland, where its distribution is limited to Lamington National Park.
Mycena epipterygia is a species of fungus in the family Mycenaceae of mushrooms commonly found in Europe. It is commonly known as yellowleg bonnet or yellow-stemmed mycena. The species is saprotrophic and its appearance is quite variable. For example, a number of members of the genus Mycena, some parts of the fungus are bioluminescent, including in this species, the mycelium. Mycena nivicola has been suggested as a separate species name for the Western variety.
Mycena stylobates, commonly known as the bulbous bonnet, is a species of inedible mushroom in the family Mycenaceae. Found in North America and Europe, it produces small whitish to gray fruit bodies with bell-shaped caps that are up to 15 mm (0.6 in) in diameter. The distinguishing characteristic of the mushroom is the fragile stipe, which is seated on a flat disk marked with distinct grooves, and fringed with a row of bristles. The mushrooms grow in small troops on leaves and other debris of deciduous and coniferous trees. The mushroom's spores are white in deposit, smooth, and ellipsoid-shaped with dimensions of 6–10 by 3.5–4.5 μm. In the development of the fruit body, the preliminary stipe and cap structures appear at the same time within the primordium, and hyphae originating from the stipe form a cover over the developing structures. The mycelia of the mushroom is believed to have bioluminescent properties.
Mycena luxaeterna, commonly known as the eternal light mushroom, is a species of fungus in the family Mycenaceae. The mushrooms have parachute-shaped caps which start off darkly grayish-brown, changing to grayish-yellow or pale grayish-brown with a pale white ring at the edge when mature, and reach up to 2 cm (0.79 in) in diameter. Their thin, cylindrical, hollow, fragile stems up to 8 mm (0.31 in) in diameter are covered in a thick gel and emit a constant yellow-green bioluminescence. The gills are attached. The mushroom has a slightly radish-like smell and similar slightly bitter taste.
Mycena asterina is a species of agaric fungus in the family Mycenaceae. It is found in São Paulo state, Brazil, where it grows singly or scattered on fallen leaves in Atlantic forests. The fruit bodies of the fungus are bioluminescent.
Mycena illuminans is a species of agaric fungus in the family Mycenaceae. It was first found on the trunk of Calamus (palm) in Jawa, Indonesia. It is bioluminescent.
Mycena tintinnabulum is a European species of agaric fungus in the family Mycenaceae. The mycelium, but not the fruit body, is bioluminescent.
Mycena zephirus is a species of agaric fungus in the family Mycenaceae. It is bioluminescent.
Mycena singeri is a species of agaric fungus in the family Mycenaceae. Described as new to science in 1988 by Jean Lodge, it is bioluminescent. In 2007, the first reported luminescent species were found from a single site in primary Atlantic Forest habitat in the Alto Ribeira Tourist State Park, São Paulo State, Brazil.
Roridomyces irritans is a species of fungus in the genus Roridomyces, family Mycenaceae. Originally described from New Caledonia as Mycena irritans by Egon Horak in 1978, the species was transferred to Roridomyces in 1994. The fruit bodies are bioluminescent.
Roridomyces austrororidus, commonly known as the austro dripping bonnet, is a species of agaric fungus in the family Mycenaceae. Described as new to science in 1962 by American mycologist Rolf Singer, it is found in South America, New Zealand, and Australia, where it grows on rotting wood.
Atheniella is an agaric fungal genus that produces mostly brightly colored mycenoid fruit bodies on small plant debris on forest floors, in fields and bogs. It is not a member of the Mycenaceae, and unlike most Mycenaceae, its basidiospores and tissues do not react with iodine. Atheniella species were most recently classified in Mycena because of their stature. However, they lack amyloid spores and tissues bewildering taxonomists, leading to temporary placements in Hemimycena and Marasmiellus before being phylogenetically excluded from both genera and the Mycenaceae. Most recently the genus has been classified in the Porotheleaceae. Currently 12 species are recognized.
Roridomyces appendiculatus is a species of fungus in the genus Roridomyces, family Mycenaceae. It is found in Europe.
Roridomyces mauritianus is a species of fungus in the genus Roridomyces, family Mycenaceae. It is found in Africa. The species was originally named Mycena mauritiana in 2001.
Roridomyces subglobosus is a species of fungus in the genus Roridomyces, family Mycenaceae.
Roridomyces praeclarus is a species of fungus in the genus Roridomyces, family Mycenaceae.
Mycena lazulina is a bioluminescent species of mushroom in the genus Mycena and family Mycenaceae.
