Russula mustelina, commonly known as the russet brittlegill, is a basidiomycete mushroom of the genus Russula native to Europe and North America. Swedish mycologist Elias Magnus Fries described the species in his 1838 book Epicrisis Systematis Mycologici seu Synopsis Hymenomycetum. [1]

Description

Illustration

The fruit bodies appear in autumn and can be partly submerged in the soil. The cap is 7–12 cm (2.8–4.7 in) wide, occasionally reaching 16 cm (6.3 in), with a shape ranging from convex (in young specimens) to flattened, sometimes with a shallow central depression. The cap surface is dry and can be slightly sticky when wet. The colour is pale yellow to yellow-brown with wine-coloured cap margin and can be discoloured with wine-coloured splotches with age. The white flesh is 3–10 mm (0.1–0.4 in) thick under the cap and has a mild taste. The cream gills have an attachment to the stem ranging from adnate to adnexed. Fruit bodies have almost no odour. The hard white stem measures 4–9 cm (1.6–3.5 in) long by 2–3 cm (0.8–1.2 in) thick, and is roughly the same width throughout its length, although it can be a little thicker near the base. Its surface is dry and smooth. [2]

Russula mustelina produces a yellowish spore print. The roundish spores have dimensions of 7.5–10.5 by 6.5–9  μm, with a reticulate (web-like) and ridged surface marked by occasional warts. [2]

Russula basifurcata is a similar species with smaller fruit bodies associated with oak trees at lower altitudes. The gills are forked near the stem. [2]

Ecology

Russula mustelina occurs in coniferous forests above 1,600 m (5,200 ft) in the Sierra Nevada and Cascade Range in western North America. [2] It is a component of rare peat bog habitat in the eastern Carpathians in Romania, where it is associated with European spruce ( Picea abies ). [3] It also grows in the Ivory Coast where it is picked and eaten. [4]

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

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.

<i>Tricholoma pardinum</i> Species of agaric fungus endemic to North America, Europe, and parts of Asia

Tricholoma pardinum, commonly known as spotted tricholoma, tiger tricholoma, tigertop, leopard knight, or dirty trich, is a gilled mushroom widely distributed across North America, Europe, and parts of Asia. It is generally found in beech woodland in summer and autumn. Two subspecies have been described from southern Europe. First officially described by Christiaan Hendrik Persoon in 1801, T. pardinum has had a confusing taxonomic history that extends over two centuries. In 1762, German naturalist Jacob Christian Schäffer described the species Agaricus tigrinus with an illustration corresponding to what is thought to be T. pardinum, and consequently, the name Tricholoma tigrinum has been used erroneously in some European field guides.

<i>Cortinarius caperatus</i> Species of fungus

Cortinarius caperatus is an edible mushroom of the genus Cortinarius found in northern regions of Europe and North America. It was known as Rozites caperata for many years before genetic studies revealed that it belonged to the genus Cortinarius. The fruit bodies appear in autumn in coniferous and beech woods as well as heathlands in late summer and autumn. The ochre-coloured cap is up to 10 cm (4 in) across and has a fibrous surface. The clay-colored gills are attached to the stipe under the cap, and the stipe is whitish with a whitish ring. The Latin specific name, caperatus, means wrinkled, and refers to the distinctive texture of the cap. The flesh has a mild smell and flavor.

<i>Russula aeruginea</i> Species of fungus

Russula aeruginea, also known as the grass-green russula, the tacky green russula, or the green russula, is an edible Russula mushroom. Widely distributed in northern temperate regions, it is usually found under birch, mostly in pine forests. The very poisonous death cap can have a similar appearance, especially from above.

<i>Lactifluus volemus</i> Species of edible fungus in the family Russulaceae widely distributed in the northern hemisphere

Lactifluus volemus, formerly known as Lactarius volemus, and commonly known as the weeping milk cap or bradley, is a species of fungus in the family Russulaceae. It is widely distributed in the northern hemisphere, in temperate regions of Europe, North America and Asia as well as some subtropical and tropical regions of Central America and Asia. A mycorrhizal fungus, its fruit bodies grow on the ground at the base of various species of trees from summer to autumn, either individually or in groups. It is valued as an edible mushroom, and is sold in markets in Asia. Several other Lactifluus mushrooms resemble L. volemus, such as the closely related edible species L. corrugis, but these can be distinguished by differences in distribution, visible morphology, and microscopic characteristics. L. volemus produces a white spore print and has roughly spherical spores about 7–8 micrometres in diameter.

<i>Cantharellus lateritius</i> Species of fungus

Cantharellus lateritius, commonly known as the smooth chanterelle, is a species of edible fungus in the mushroom family Cantharellaceae. An ectomycorrhizal species, it is found in Asia, Africa, and North America. The species has a complex taxonomic history, and has undergone several name changes since its first description by American mycologist Lewis David de Schweinitz in 1822. The fruit bodies of the fungus are brightly colored yellow to orange, and usually highly conspicuous against the soil in which they are found. At maturity, the mushroom resembles a filled funnel with the spore-bearing surface along the sloping outer sides. The texture of the fertile undersurface (hymenium) of the caps is a distinguishing characteristic of the species: unlike the well-known golden chanterelle, the hymenium of C. lateritius is much smoother. Chemical analysis has revealed the presence of several carotenoid compounds in the fruit bodies.

<i>Cortinarius varius</i> Species of fungus

Cortinarius varius, also known as the contrary webcap, is a basidiomycete mushroom of the genus Cortinarius. The mushroom has orangish-yellow caps that reach up to 10 cm (3.9 in) in diameter, and thick club-shaped stems up to 10 cm (3.9 in) long.
