Inocybe hystrix is an agaric fungus in the family Inocybaceae. It forms mycorrhiza with surrounding deciduous trees. Fruit bodies are usually found growing alone or in small groups on leaf litter during autumn months. Unlike many Inocybe species, Inocybe hystrix is densely covered in brown scales, a characteristic that aids in identification. The mushroom also has a spermatic odour that is especially noticeable when the mushroom is damaged or crushed.

Contents

Like many other Inocybe mushrooms, Inocybe hystrix contains dangerous amounts of muscarine and should not be consumed.

Taxonomy

The species was first described in 1838 by Elias Fries under the name Agaricus hystrix. [2] Finnish mycologist Petter Karsten later (1879) transferred it to Inocybe. [3]

Description

Fruit bodies have convex to plano-convex caps measuring 3–5.5 cm (1.2–2.2 in) in diameter. The caps are dry with scales that can be either erect or flat on the surface. The colour is brown in the centre, becoming paler towards the edges. The flesh is white, and has a spermatic odour and mild taste. The gills are closely spaced, white to dull brown, and have fringed edges. The stipe measures 3–9 cm (1.2–3.5 in) long by 0.5–1 cm (0.2–0.4 in) thick, and is roughly the same width throughout its length; like the cap, it is scaly. [4]

The spore print is cinnamon brown. spores are roughly almond-shaped, smooth, inamyloid, and measure 8–12.5 by 5–6.5  μm. Clamp connections are present in the hyphae. [4]

The species is poisonous. [5]

Habitat and distribution

In North America and Europe, Inocybe hystrix grows in deciduous forest, especially beech. [6] In Costa Rica, it is found in the Cordillera Talamanca, where it associates with Quercus costaricensis at elevations around 3,000 meters (9,800 ft). [4]

<i>Inocybe</i> Genus of fungi

Inocybe is a large genus of mushroom-forming fungi with over 1400 species, including all forms and variations. Members of Inocybe are mycorrhizal, and some evidence shows that the high degree of speciation in the genus is due to adaptation to different trees and perhaps even local environments.

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

Amanita arocheae, also known as the Latin American death cap, is a mushroom of the large genus Amanita, which occurs in Colombia, Central America and South America. Deadly poisonous, it is a member of section Phalloideae and related to the death cap, A. phalloides.

<i>Inocybe corydalina</i> var. <i>corydalina</i> Species of fungus

Inocybe corydalina var. corydalina, commonly known as the greenflush fibrecap, is a member of the genus Inocybe which is widely distributed in temperate forests. It is a small mycorrhizal mushroom which contains a small amount of the hallucinogen psilocybin.

<i>Inocybe geophylla</i> Species of fungus

Inocybe geophylla, commonly known as the earthy inocybe, common white inocybe or white fibercap, is a poisonous mushroom of the genus Inocybe. It is widespread and common in Europe and North America, appearing under both conifer and deciduous trees in summer and autumn. The fruiting body is a small all-white or cream mushroom with a fibrous silky umbonate cap and adnexed gills. An all-lilac variety lilacina is also common.

<i>Mythicomyces</i> Genus of fungi

Mythicomyces is a fungal genus in the family Mythicomycetaceae. A monotypic genus, it contains the single species Mythicomyces corneipes, first described by Elias Fries in 1861. The fungus produces fruit bodies with shiny yellowish-orange to tawny caps that are 1–3 cm (0.4–1.2 in) in diameter. These are supported by stems measuring 2–5.7 cm (0.8–2.2 in) long and 1–2 mm thick. A rare to uncommon species, it is found in northern temperate regions of North America and Europe, where it typically fruits in groups, in wet areas of coniferous forests. There are several species with which M. corneipes might be confused due to a comparable appearance or similar range and habitat, but microscopic characteristics can be used to reliably distinguish between them.

<i>Inocybe lacera</i> Species of fungus

Inocybe lacera, commonly known as the torn fibrecap, is a poisonous species of mushroom in the genus Inocybe. Its appearance is that of a typical "little brown mushroom": small, brown and indistinct. However, it is distinguishable by its microscopic features, particularly its long, smooth spores. As with many other species of Inocybe, I. lacera contains the poisonous chemical muscarine which, if consumed, can lead to salivation, lacrimation, urination, defecation, gastrointestinal problems and vomiting. Found in Europe and North America, it typically grows in autumn in mixed woods, favouring sandy soil. There are several documented subspecies in addition to the main I. lacera var lacera, including the dwarf form I. lacera var. subsquarrosa and I. lacera var. heterosperma, found in North America.

<i>Lactarius indigo</i> Edible fungus in the family Russulaceae from eastern North America, East Asia, and Central America

Lactarius indigo, commonly known as the indigo milk cap, indigo milky, the indigo lactarius, or the blue milk mushroom, is a species of agaric fungus in the family Russulaceae. It is a widely distributed species, growing naturally in eastern North America, East Asia, and Central America; it has also been reported in southern France. L. indigo grows on the ground in both deciduous and coniferous forests, where it forms mycorrhizal associations with a broad range of trees. The fruit body color ranges from dark blue in fresh specimens to pale blue-gray in older ones. The milk, or latex, that oozes when the mushroom tissue is cut or broken — a feature common to all members of the genus Lactarius — is also indigo blue, but slowly turns green upon exposure to air. The cap has a diameter of 5–15 cm (2–6 in), and the stem is 2–8 cm (0.8–3 in) tall and 1–2.5 cm (0.4–1.0 in) thick. It is an edible mushroom, and is sold in rural markets in China, Guatemala, and Mexico. In Honduras, the mushroom is called a chora, and is generally eaten with egg; generally as a side dish for a bigger meal.

<i>Mycena cinerella</i> Species of fungus

Mycena cinerella, commonly known as the mealy bonnet, is an inedible species of mushroom in the family Mycenaceae. It is found in Europe and the United States, where it grows in groups on fallen leaves and needles under pine and Douglas fir.

<i>Pulveroboletus ravenelii</i> Species of fungus

Pulveroboletus ravenelii, commonly known as Ravenel's bolete or the powdery sulfur bolete, is a species of bolete fungus in the family Boletaceae. Described as new to science in 1853, the widely distributed species is known from Asia, Australia, North America, Central America, and South America. Mycorrhizal with oak, the fungus fruits on the ground singly, scattered, or in groups in woods. Fruit bodies (mushrooms) have convex to flat, yellowish to brownish-red caps up to 10 cm (4 in) in diameter. On the cap underside, the pore surface is bright yellow before turning dingy yellow to grayish brown with age; it stains greenish blue then grayish brown after injury. A cottony and powdery partial veil remains as a ring on the stipe. The mushrooms are edible, and have been used in traditional Chinese medicine and for mushroom dyeing.
