Lepiota helveola is a gilled mushroom of the genus Lepiota in the order Agaricales. It was described by Italian mycologist Giacomo Bresadola in 1882.

Contents

It has white gills and spores. They typically have rings on the stems,

Like several other species of the genus Lepiota, it contains amatoxins which may cause potentially fatal liver injury.

Description

Cap 1.5–3 cm in diameter, convex to spreading, often with flattened disc, sometimes depressed, fibrillose, with fibrous scales at disc on whitish ground, fine concentric scales recurved around edges, moderate reddish brown, sometimes tinged pink to vinous, with a straight or wavy margin, sometimes raised with age. Blades free, set on a dark collarium on one or two thirds, white then creamy buff, tight, with finely fringed edges. Stem 2–4 x 0.3–0.7 mm, equal, stuffed then hollow, with bands of appressed, encrusted, brown fibrous scales on a white to pink-tinged ground, turning brown on crumpling, with a sometimes fleeting ring, similar to foot scales. Smell and flavor very sweet, fungal and slightly fragrant odor, sometimes indistinct, and fungal then metallic flavor. [1]

<i>Lepiota</i> Genus of fungi

Lepiota is a genus of gilled mushrooms in the family Agaricaceae. All Lepiota species are ground-dwelling saprotrophs with a preference for rich, calcareous soils. Basidiocarps are agaricoid with whitish spores, typically with scaly caps and a ring on the stipe. Around 400 species of Lepiota are currently recognized worldwide. Many species are poisonous, some lethally so.

<i>Macrolepiota procera</i> Species of fungus

Macrolepiota procera, the parasol mushroom, is a basidiomycete fungus with a large, prominent fruiting body resembling a parasol. It is a fairly common species on well-drained soils. It is found solitary or in groups and fairy rings in pastures and occasionally in woodland. Globally, it is widespread in temperate regions.

<i>Echinoderma asperum</i> Species of fungus

Echinoderma asperum or Lepiota aspera, sometimes known commonly as the freckled dapperling, is a large, brownish, white-gilled mushroom, with a warty or scaly cap. It lives in woodland, or on bark chips in parks, and gardens.

<i>Leucocoprinus cepistipes</i> Species of fungus

Leucocoprinus cepistipes, is a species of fungus in the family Agaricaceae. It is typically found on wood debris, such as wood chips but may also grow in potted plants or greenhouses. Typical characteristics include a fine-scaled bell-shaped cap, a partial veil, and a tendency to bruise a yellow to brown when handled.

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

Lepiota clypeolaria, commonly known as the shield dapperling or the shaggy-stalked Lepiota, is a common mushroom in the genus Lepiota. It is widely distributed in northern temperate zones, where it grows in deciduous and coniferous forest. Fruit bodies have a brownish cap, a shaggy stipe with a collapsed, sheathing ring or ring zone, and spindle-shaped spores.

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

Lepiota babruzalka is an agaric mushroom of the genus Lepiota in the order Agaricales. Described as new to science in 2009, it is found in Kerala State, India, where it grows on the ground in litterfall around bamboo stems. Fruit bodies have caps that measure up to 1.3 cm (0.5 in) in diameter, and are covered with reddish-brown scales. The cap is supported by a long and slender stem up to 4.5 cm (1.8 in) long and 1.5 millimetres (0.1 in) thick. One of the distinguishing microscopic features of the species is the variably shaped cystidia found on the edges of the gills.

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

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.

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

Lepiota cristata, commonly known as the stinking dapperling, brown-eyed parasol, or the stinking parasol, is an agaric and possibly poisonous mushroom in the family Agaricaceae. A common and widespread species—one of the most widespread fungi in the genus Lepiota—it has been reported from Europe, northern Asia, North America, and New Zealand. It fruits on the ground in disturbed areas, such as lawns, path and road edges, parks, and gardens. The species produces fruit bodies characterized by the flat, reddish-brown concentric scales on the caps, and an unpleasant odour resembling burnt rubber. Similar Lepiota species can sometimes be distinguished from L. cristata by differences in cap colour, stipe structure, or odour, although some species can only be reliably distinguished through the use of microscopy.

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

Lepiota maculans is a rare species of agaric fungus in the family Agaricaceae. It was originally collected in Missouri, and then 105 years later in eastern Tennessee. It is the only member of Lepiota known to have a pink spore print instead of the usual white or cream color. The fruit bodies have caps up to 4 cm (1.6 in) in diameter, with brownish, sparsely scaled centers. The gills are closely spaced, not attached to the stipe, and discolor reddish at the edges.

<i>Leucocoprinus ianthinus</i> Species of fungus

Leucocoprinus ianthinus is a species of mushroom producing fungus in the family Agaricaceae. Like several other Leucocoprinus species it may have originated in a tropical climate but now finds a home in plant pots, greenhouses and compost piles in many countries. It is not seen in plant pots with the same kind of regularity as the well known Leucocoprinus birnbaumii and not seen in the wild as frequently as Leucocoprinus brebissonii.
