Taxonomy

The species was described in a 2009 Mycotaxon article, along with eight other new Lepiota species. The specific epithet anupama derives from the Sanskrit word for "without comparison". The type collection was made on the campus of the University of Calicut in 2006. [1]

Description

The fruit bodies of Lepiota anupama have caps that are first convex before flattening out in maturity, often developing a shallow umbo. The cap attains a diameter of 1.5–2.0 cm (0.6–0.8 in). The color of the cap surface ranges from brownish grey to reddish gray. Its surface has flaky scales that are more concentrated near the center. There are fine radial grooves near the cap margin; young specimens, the margin is curved inward, but it straightens as it ages, and eventually develops cracks. The gills are white, and free from attachment to the stem. They are crowded together closely, and there are 2–3 tiers of lamellulae (short gills that do not extend completely from the cap margin to the stem). Viewed with a hand lens, the gill edges appear to have fringes. The white stem is centrally attached to the cap, roughly cylindrical with a slight widening towards the base, and measures 2.3–4.0 cm (0.91–1.57 in) long by 2–3 mm wide. Initially solid, the stem becomes hollow in age. The stem has a membranous, whitish ring on its upper half. The flesh is thin, white, and lacks any distinctive odor. [1]

Lepiota anupama produces a white spore print. The spores are roughly elliptical in shape, thick-walled, hyaline (translucent), and measure 5–7 by 3.5–5  μm. Spores contain refractive oil droplets. The basidia (spore-bearing cells) are club-shaped, four-spored with sterigmata up to 3 μm long, and measure 14–20 by 7–10 μm. [1]

Habitat and distribution

The fruit bodies of Lepiota anupama grow singly or scattered on soil rich in humus. Common in the Kozhikode and Malappuram districts of Kerala, fruiting usually occurs after the occurrence of heavy rains during monsoon season, continuing for about 1.5 weeks. [1]

<i>Lepiota brunneoincarnata</i> Species of fungus

Lepiota brunneoincarnata, the deadly dapperling, is a gilled mushroom of the genus Lepiota in the order Agaricales. Widely distributed in Europe and temperate regions of Asia as far east as China, it grows in grassy areas such as fields, parks and gardens, and is often mistaken for edible mushrooms. The mushroom has a brown scaled cap up to 4 cm wide with a pinkish brown stem and white gills. It is highly toxic, with several deaths having been recorded as it resembles the edible grey knight and fairy ring champignon.

<i>Dendrocollybia</i> Genus of fungi in the family Tricholomataceae

Dendrocollybia is a fungal genus in the family Tricholomataceae of the order Agaricales. It is a monotypic genus, containing the single species Dendrocollybia racemosa, commonly known as the branched collybia or the branched shanklet. The somewhat rare species is found in the Northern Hemisphere, including the Pacific Northwest region of western North America, and Europe, where it is included in several Regional Red Lists. It usually grows on the decaying fruit bodies of other agarics—such as Lactarius and Russula—although the host mushrooms may be decayed to the point of being difficult to recognize.

<i>Entoloma austroprunicolor</i> Species of fungus

Entoloma austroprunicolor is a species of agaric fungus in the family Entolomataceae. Described as new to science in 2007, it is found in Tasmania, where it fruits on the ground of wet sclerophyll forests in late spring to early winter. The fruit bodies (mushrooms) have reddish-purple caps measuring up to 5 cm (2.0 in) in diameter supported by whitish stipes measuring 3–7.5 cm (1.2–3.0 in) long by 0.2–0.6 cm (0.1–0.2 in) thick. On the cap underside, the crowded gills are initially white before turning pink as the spores mature.

<i>Lactarius alnicola</i> Species of fungus

Lactarius alnicola, commonly known as the golden milkcap, is a species of fungus in the family Russulaceae. The fruit bodies produced by the fungus are characterized by a sticky, vanilla-colored cap up to 20 cm (7.9 in) wide with a mixture of yellow tones arranged in faint concentric bands. The stem is up to 5 cm (2.0 in) long and has yellow-brown spots. When it is cut or injured, the mushroom oozes a white latex, which has an intensely peppery taste. The acrid taste of the fruit bodies renders them unpalatable. The fungus is found in the western United States and Mexico, where it grows in mycorrhizal associations with various coniferous trees species, such as spruce, pine and fir, and deciduous species such as oak and alder. It has also been collected in India. Two varieties have been named: var. pitkinensis, known from Colorado, and var. pungens, from Michigan.

<i>Lactarius argillaceifolius</i> Species of fungus

Lactarius argillaceifolius is a species of fungus in the family Russulaceae. The mushrooms produced by the fungus have convex to flattened drab lilac-colored caps that are up to 18 cm (7.1 in) wide. The cream-colored gills are closely spaced together and extend slightly down the length of the stem, which is up to 9 cm (3.5 in) long by 3.5 cm (1.4 in) thick. The mushroom produces an off-white latex when injured that stains the mushroom tissue brownish.

<i>Pluteus nevadensis</i> Species of fungus

Pluteus nevadensis is a species of fungus in the agaric family Pluteaceae. Described as new to science in 2010, the species is known only from subtropical and pine forests in Mexico, where it grows on rotting pine and oak wood. Fruit bodies (mushrooms) have red-orange caps up to 3.8 cm (1.5 in) in diameter with a shape ranging from conic, convex, or flattened, depending on their age. The silky yellow stems are up to 4.5 cm (1.8 in) long. It is similar in appearance to Pluteus aurantiorugosus, with which it shares an orange- or scarlet-colored cap and a yellow stem. P. nevadensis can be distinguished from this and other superficially similar Pluteus species by differences in microscopic characteristics.

<i>Parasola auricoma</i> Species of fungus

Parasola auricoma is a species of agaric fungus in the family Psathyrellaceae. First described scientifically in 1886, the species is found in Europe, Japan, and North America. The mushroom was reported in February 2019 in Colombia, in the city of Bogota by the mycologist Juan Camilo Rodriguez Martinez. The small, umbrella-shaped fruit bodies (mushrooms) of the fungus grow in grass or woodchips and are short-lived, usually collapsing with age in a few hours. The caps are up to 6 cm (2.4 in) wide, initially elliptical before flattening out, and colored reddish-brown to greyish, depending on their age and hydration. They are pleated with radial grooves extending from the center to the edge of the cap. The slender, whitish stems are up to 12 cm (4.7 in) long and a few millimeters thick. Microscopically, P. auricoma is characterized by the presence of setae in its cap cuticle. This characteristic, in addition to the relatively large, ellipsoid spores can be used to distinguish it from other morphologically similar Parasola species.

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.
