Lepiota nirupama is a species of agaric fungus of the genus Lepiota in the order Agaricales. Known only from Kerala State in India, it was described as new to science in 2009.
The species was described in the journal Mycotaxon in 2009 by T.K.A. Kumar and P. Manimohan. The type collections was made in July, 2005, in the Thiruvananthapuram District of Kerala State, India. The specific epithet nirupama is derived from the Sanskrit word for "unequaled". [1]
Fruit bodies of Lepiota nirupama have caps that start out roughly spherical before becoming convex, ultimately reaching dimensions of 2–3 cm (0.8–1.2 in). The cap color ranges from light brown to dark brown (sometimes with reddish tones), and the surface is covered with small, wart-like to conical scales that eventually slough off to leave a reticulate (net-like) pattern. This pattern is most prevalent in the center of the cap, but diminishes toward the margin. In mature specimens, the cap cuticle peels off to reveal the underlying white flesh. The cap margin is initially curved inward but straightens out in maturity. The gills are free from attachment to the stem, and moderately crowded, with 4–5 tiers of interspersed lamellulae (short gills). The gill edges are fringed, although a hand lens may be needed to see this detail. The stem is centrally attached to the cap, hollow, and measures 3.2–4 cm (1.3–1.6 in) long by 2–5 mm (0.1–0.2 in) thick. The stem bears a whitish, membranous or fibrillose ring on its upper half that can be moved up and down. The lower surface of the ring is densely covered with fluffy whitish to light brown scales. The stem color is light brown to reddish-brown below the level of the ring, and it has small pyramidal scales scattered about its surface; above the ring, the stem is whitish. There is white mycelium at the base of the stem. The flesh of the mushroom is up to 6 mm (0.24 in) thick, and lacks any distinct odor. [1]
Spores are smooth, elliptical, hyaline (translucent), and measure 4–6 by 3 μm. They contain refractive oil droplets. The basidia (spore-bearing cells) are cylindrical to club-shaped, hyaline, four-spored with sterigmata up to 2 μm long, and measure 15–20 by 6–8 μm. Cheilocystidia are plentiful, thin-walled, club-shaped or sac-like with a pedicel, and have dimensions of 10–34 by 7–20 μm; there are no cystidia on the gill faces (pleurocystidia). [1]
The fruit bodies of Lepiota nirupama grow singly to scattered on the ground among bamboo roots both dead and living. It is known only from the type locality. [1]
Pulveroboletus bembae is a species of fungus in the family Boletaceae that was first described in 2009. It is known only from the rainforest of northern Gabon, a region known for its high level of species diversity. Like all boletes, P. bembae has fleshy fruit bodies that form spores in tubes perpendicular to the ground on the underside of the cap. These yellowish tubes form a surface of pores, each about 1–2 mm in diameter. The brownish caps may reach up to 3.5 cm (1.4 in) wide, and rest atop pale brown stems up to 5.5 cm (2.2 in) long. The stems have a woolly, whitish yellow ring of tissue that is short-lived, and may be absent in older specimens. The spores of P. bembae are spindle- or fuse-shaped, and have rough surfaces—a detail observable when viewed with scanning electron microscopy. The fungus grows in a mycorrhizal relationship with Gilbertiodendron dewevrei, the dominant tree species of the Guineo-Congolian rainforest. Other similar Pulveroboletus species in the area include P. annulus and P. croceus, which may be differentiated from P. bembae by a combination of macro- and microscopic characteristics.
Amanita nothofagi is a species of fungus in the family Amanitaceae. Endemic to New Zealand, the species was first described by mycologist Greta Stevenson in 1962. The fruit bodies have dark brown caps that are up to 13 cm (5.1 in) in diameter and covered with patches of soft greyish-brown scales or warts. The gills underneath the cap are crowded together, free from attachment to the stem, and white, becoming tinged with yellow in age. The stem of the mushroom is 4–14 cm (1.6–5.5 in) long by 0.5–2.5 cm (0.2–1.0 in) thick, and has a ring. The spore print is white, and individual spores are spherical to ellipsoid, measuring 7.5–9 by 7.5–9 micrometres. The mushroom may be confused with another New Zealand species, A. australis, but can be distinguished by certain characteristics. Amanita nothofagi is a mycorrhizal species, and grows in association with native New Zealand trees such as Southern Beech.
Mycena lanuginosa is a species of mushroom in the family Mycenaceae. First collected in 2000 and reported as a new species in 2007, it is known only from lowland oak-dominated forests in central Honshu in Japan. The small mushroom is characterized by its grooved, grayish-brown to violet-brown cap up to 11 mm (0.43 in) in diameter, and the slender grayish-brown to reddish-brown stem covered with minute, fine, soft hairs. The mushroom produces amyloid spores. Microscopic distinguishing features include the smooth, spindle-shaped cheilocystidia and pleurocystidia and the diverticulate elements in the outer layer of the cap and the stem.
Mycena multiplicata is a species of mushroom in the family Mycenaceae. First described as a new species in 2007, the mushroom is known only from the prefecture of Kanagawa, Japan, where it grows on dead fallen twigs in lowland forests dominated by oak. The mushroom has a whitish cap that reaches up to 13 mm (0.51 in) in diameter atop a slender stem 15 to 20 mm long and 1 to 1.3 mm thick. On the underside of the cap are whitish, distantly spaced gills that are narrowly attached to the stem. Microscopic characteristics of the mushroom include the amyloid spores, the pear-shaped to broadly club-shaped cheilocystidia which are covered with a few to numerous, unevenly spaced, cylindrical protuberances, the lack of pleurocystidia, and the diverticulate hyphae in the outer layer of the cap and stem. The edibility of the mushroom is unknown.

Lepiota castaneidisca is a species of agaric fungus in the family Agaricaceae. Formally described in 1912, it was for a long time considered the same species as the similar Lepiota cristata until molecular analysis reported in 2001 demonstrated that it was genetically distinct. It is most common in coastal and northern California, and has also been recorded in Mexico. A saprobic species, it is usually found under redwood and Monterey cypress. Its fruit bodies (mushrooms) have white caps with an orange-red to orange-brown center that measure up to 3.2 cm (1.3 in) wide. The cream-colored to light pink stems are up to 6.5 cm (2.6 in) long by 0.2–0.6 cm (0.1–0.2 in) thick, and have a ring. L. castaneidisca can be distinguished from other similar Lepiota species by differences in habitat, macroscopic, or microscopic characteristics.
