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 caps do not glow). The gills are attached. The mushroom has a slightly radish-like smell and similar

Atheniella is an agaric fungal genus that produces mostly brightly colored (yellow, pink, orange, or red) 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

Chaetothiersia is a fungal genus in the family Pyronemataceae. It is monotypic, containing the single species Chaetothiersia vernalis collected from California.

Neonothopanus gardneri, locally known as flor de coco, is a bioluminescent fungus native to Goiás, Piauí and Tocantins states in Brazil. The fungus was first discovered in 1839 by the English botanist George Gardner, after he came across some youths playing with glowing material in the streets of Villa de Natividade in Goiás state in Brazil. Initially thinking it was a firefly, he then discovered it was a mushroom—known as Flor de Coco locally—that was common locally and found on decaying palm leaves. Gardner sought to call it Agaricus phosphorescens. However, his colleague Miles Joseph

Mycena guldeniana is a species of agaric fungus in the family Mycenaceae. Described as new to science in 2011, it occurs in Norway. The specific epithet guldeniana honors Norwegian mycologist Gro Gulden. The whitish caps of the fruit bodies are hemispherical before flattening out, and measure 1–2 mm in diameter. They appear solitarily or in small groups on the fallen leaves (occasionally on twigs) of Salix species. The spores are broadly ellipsoid to pip-shaped, smooth, amyloid, and measure 7.5–8.7–10 by 4.8–5.5–6.5 μm.

Phallus drewesii is a species of stinkhorn mushroom endemic to São Tomé that was first described in 2009. It can be distinguished from the other 28 stinkhorn mushrooms in the genus Phallus by its small size, white net-like stem, brown spore-covered head and by its stem curving down instead of up. The species was named after Robert Drewes, Curator of Herpetology at the California Academy of Sciences.
