Lepiota ignivolvata, sometimes known commonly as the orange-girdled parasol, is a fairly rare member of the gilled mushroom genus Lepiota . [1] It is among the larger species in this group, growing in coniferous or deciduous woodland during autumn; it has a primarily European distribution. Being inedible, and perhaps poisonous, it should not be gathered for culinary use. Many of the species in this genus are deadly.

Description

The cap is between 4 and 10 centimetres (1.6 and 3.9 in) in diameter. It is convex, later flat, and with a raised central boss (umbo). The centre of the cap is reddish brown, or orange-brown, breaking into small scales, which are fewer, and lighter towards the margin. [1] The best identification aid is the orange (somewhat indented) ring, which is low on the white, slightly bulbous to club-shaped stem, [2] which often has an orange flush at its base.

The gills are white to cream, giving a white spore print. [1] They are free of the stem, and are fairly crowded together. The flesh is white throughout, and has an unpleasant chemical smell, similar to that which is produced when cutting metal; [2] the odor has also been compared to rubber. [3] L. ignivolvata has an unpleasant, rancid taste. [3] The spores are spindle (fusiform) or almond (amygdaloid) in shape, with dimensions of 913 to 57; μm. [3]

The similar species Lepiota ventriosospora and Lepiota cristata lack the orange colouring on the ring.

Lepiota ignivolvata belongs to the section Fusisporae within genus Lepiota, whose members are characterized by long spindle-shaped spores and a fluffy stem beneath the ring. [4]

Naming history

This species was originally described by Marcel Josserand and M. Bousset in 1948 in the French language in the quarterly bulletin of the French Mycological Society. [5] However at that time the nomenclatural rules demanded a description in Latin, and so the species did not officially exist until when in 1972 the same two authors republished with a short Latin text in the monthly bulletin of the "Société linnéenne de Lyon" (Linnaean Society of Lyon). [6] For this reason the full correct author designation is "Bousset & Joss. ex Joss." [7]

Distribution and habitat

Lepiota ignivolvata is widespread across Europe, its stronghold being in central to southern Europe. [2] In Britain it is rare, and resides on the British Red Data list. It appears in deciduous, and coniferous woods, in autumn, and seems to favour beech.

<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>Entoloma sinuatum</i> Species of poisonous fungus in the family Entolomataceae found across Europe and North America

Entoloma sinuatum is a poisonous mushroom found across Europe and North America. Some guidebooks refer to it by its older scientific names of Entoloma lividum or Rhodophyllus sinuatus. The largest mushroom of the genus of pink-spored fungi known as Entoloma, it is also the type species. Appearing in late summer and autumn, fruit bodies are found in deciduous woodlands on clay or chalky soils, or nearby parklands, sometimes in the form of fairy rings. Solid in shape, they resemble members of the genus Tricholoma. The ivory to light grey-brown cap is up to 20 cm (7.9 in) across with a margin that is rolled inward. The sinuate gills are pale and often yellowish, becoming pink as the spores develop. The thick whitish stem has no ring.

<i>Amanita ovoidea</i> Species of fungus

The European white egg, bearded amanita or European egg amidella, is a species of fungus of the genus Amanita in the family Amanitaceae. It is a large, white-colored fungus, often tinged with cream. Native to Europe, it is found on plains as well as mountains in the Mediterranean region. It is similar to some deadly poisonous species.

<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>Lepiota castanea</i> Species of fungus

Lepiota castanea, commonly known as the chestnut dapperling or petite parasol, is a deadly poisonous, uncommon, gilled mushroom of the genus Lepiota in the order Agaricales. It is known to contain amatoxins and consuming this fungus can be a potentially lethal proposition. It was described by French mycologist Lucien Quélet in 1881.

<i>Amanita daucipes</i> Species of fungus

Amanita daucipes is a species of fungus in the family Amanitaceae of the mushroom order Agaricales. Found exclusively in North America, the mushroom may be recognized in the field by the medium to large white caps with pale orange tints, and the dense covering of pale orange or reddish-brown powdery conical warts on the cap surface. The mushroom also has a characteristic large bulb at the base of its stem with a blunt short rooting base, whose shape is suggestive of the common names carrot-footed lepidella, carrot-foot amanita, or turnip-foot amanita. The mushroom has a strong odor that has been described variously as "sweet and nauseous", or compared to an old ham bone, or soap. Edibility is unknown for the species, but consumption is generally not recommended due its position in the Amanita subgroup Lepidella, which contains some poisonous members.

<i>Cystodermella cinnabarina</i> Species of fungus

Cystodermella cinnabarina is a basidiomycete fungus of the genus Cystodermella. Its fruiting body is a small agaric bearing a distinctive reddish-coloured grainy cap. It occurs in coniferous and deciduous forests throughout the world. Prior to 2002, this species belonged to genus Cystoderma, subsection Cinnabarina, under the name Cystoderma cinnabarinum which is still sometimes applied. Another often used synonym is Cystoderma terreyi.

<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>Tulosesus impatiens</i> Species of fungus

Tulosesus impatiens is a species of fungus in the family Psathyrellaceae. First described in 1821, it has been classified variously in the genera Psathyrella, Pseudocoprinus, Coprinarius, and Coprinus, before molecular phylogenetics reaffirmed it as a Coprinellus species in 2001. The fungus is found in North America and Europe, where the mushrooms grow on the ground in deciduous forests. The fruit bodies have buff caps that are up to 4 cm (1.6 in) in diameter, held by slender whitish stems that can be up to 10 cm (3.9 in) tall. Several other Coprinopsis species that resemble C. impatiens may be distinguished by differences in appearance, habit, or spore morphology.

<i>Amanita rubrovolvata</i> Species of fungus

Amanita rubrovolvata, commonly known as the red volva amanita, is a species of fungus in the family Amanitaceae. The fungus produces small to medium-sized mushrooms, with reddish-orange caps up to 6.5 centimetres wide. The stems are up to 10 cm (4 in) tall, cream-coloured above the ring and cream to yellowish below it. The stem ends in a roughly spherical bulb at the base, which is covered with bright orange patches.

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

Leucocoprinus fragilissimus, commonly known as the fragile dapperling, is a species of gilled mushroom in the family Agaricaceae.

<i>Ramaria stricta</i> Species of fungus

Ramaria stricta, commonly known as the strict-branch coral or strict coral mushroom, is a coral fungus of the genus Ramaria. It has a cosmopolitan distribution, and grows on dead wood, stumps, trunks, and branches of both deciduous and coniferous trees. Its fruit body is up to 10 cm tall, made of multiple slender, compact, and vertical parallel branches. Its color is typically light tan to vinaceous-brown. All parts of the mushroom will bruise when handled. There are several lookalike corals that can usually be distinguished from R. stricta by differences in coloration, bruising reaction, or microscopic features. The fungus is inedible due to its unpleasant odor and bitter taste.

<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.

Marcel Josserand was a French mycologist.

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