Lactarius resimus is a species of mushrooms in the genus Lactarius , which is considered a delicacy in Russia and some other countries of Eastern Europe when pickled in salt. There it is considered one of three tastiest edible mushrooms, along with Boletus edulis and Lactarius deliciosus , [2] though it is not held in high esteem elsewhere. The mushroom forms a mycorrhizal relationship with birch and with conifers too (pine).

The cap ranges from 4 to 15 cm in diameter. The stalk ranges from 2 to 6 cm in length and 1 to 3 cm in width. The mushroom is generally white, but stains yellow to orange. The spores are white-yellow, elliptical and bumpy. [3]

Similar species include Lactarius pubescens var. betulae and Lactarius torminosus . [3]

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

Lactarius deterrimus, also known as false saffron milkcap or orange milkcap, is a species of fungus in the family Russulaceae. The fungus produces medium-sized fruit bodies (mushrooms) with orangish caps up to 12 centimetres wide that develop green spots in old age or if injured. Its orange-coloured latex stains maroon within 30 minutes. Lactarius deterrimus is a mycorrhizal fungus that associates with Norway spruce and bearberry. The species is distributed in Europe, but has also found in parts of Asia. A visually similar species in the United States and Mexico is not closely related to the European species. Fruit bodies appear between late June and November, usually in spruce forests. Although the fungus is edible—like all Lactarius mushrooms from the section Deliciosi—its taste is often bitter, and it is not highly valued. The fruit bodies are used as source of food for the larvae of several insect species. Lactarius deterrimus can be distinguished from similar Lactarius species by difference in the mycorrhizal host or latex colour.

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

Lactarius turpis is commonly known as the ugly milk-cap in English. It is found naturally in Europe and Siberia, and has been introduced to Australia and New Zealand. While especially associated with birch, it is also found with spruce, pine and other trees in mixed woodland.

<i>Lactarius torminosus</i> Fungus in the family Russulaceae from North Africa, northern Asia, Europe, and North America

Lactarius torminosus, commonly known as the woolly milkcap or the bearded milkcap, is a large species of agaric fungus. A common and widely distributed species, it is found in North Africa, northern Asia, Europe, and North America. It was first described scientifically by Jacob Christian Schäffer in 1774 as an Agaricus, and later transferred to the genus Lactarius in 1821 by Samuel Frederick Gray. A variety, L. torminosus var. nordmanensis, is known from the United States, Canada, and Switzerland. L. torminosus officially became the type species of Lactarius in 2011 after molecular studies prompted the taxonomic reshuffling of species between several Russulaceae genera.

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

Lactarius scrobiculatus, commonly known as the scrobiculate milk cap, is a basidiomycete fungus, belonging to the genus Lactarius, whose members are called "milk caps." Taxonomy places this species into subgenus Piperites, section Zonarii, subsection Scrobiculati. The distinctive fruiting bodies of this large fungus are locally common in forests throughout Europe and North America. It is regarded as inedible by some authors, but it is nevertheless eaten in parts of Europe.

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

Lactarius uvidus, commonly known as the purple staining milk cap, is a European and North American "milk-cap" mushroom, of which the milk turns violet when the flesh is damaged. The fungi generally identified as L. uvidus are part of a complex of closely related species and varieties which are difficult to delimit definitively.

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

Lactarius pyrogalus, commonly known as the fire-milk lactarius, is a species of inedible mushroom in genus Lactarius. It is greyish and differentiated from other grey Lactarius by its widely spaced, yellow gills. It is found on the forest floor in mixed woodland, especially at the base of hazel trees.

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

Lactarius subdulcis, commonly known as the mild milkcap or beech milk cap, is an edible mushroom in the genus Lactarius. It is brown in colour, with a large number of gills and a particularly thin layer of flesh in the cap. Mycorrhizal, the mushroom is found from late summer to late autumn at the base of beech trees in small groups or individually, where it is one of the two most common species of fungi. Alternatively, it can be found in large groups in fields, sometimes with more than a hundred individual mushrooms. It is found in Europe, and, despite previous research to the contrary, is absent in North America. Although considered edible, it is not particularly useful as food due to its ivy-like taste and the fact that more choice mushrooms will be easily found at the same time. L. subdulcis is known for its abundant, sweet-tasting milk that, unlike the latex of some of its relatives, does not stain fabric yellow.

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

Lactarius chrysorrheus is a member of the genus Lactarius, whose many members are commonly known as milkcaps. It has recently been given the English (common) name of the yellowdrop milkcap. It is pale salmon in color, poisonous, and grows in symbiosis with oak trees.

<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>Lactarius subflammeus</i> Species of fungus

Lactarius subflammeus, commonly known as the orange milk cap, is a species of fungus in the family Russulaceae. It is found in western North America in the late summer and fall and is especially common in the Pacific Northwest, where it grows on the ground near conifers like pine and spruce. The brightly colored fruit bodies, which are slimy or sticky, have scarlet caps when young that soon fade to brilliant orange. The stem—typically longer than the width of the cap—is also bright orange but the gills are whitish. The mushroom secretes a whitish latex when it is cut or injured.

<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 pubescens</i> Species of fungus

Lactarius pubescens, commonly known as the downy milk cap, is a species of fungus in the family Russulaceae. It is a medium to large agaric with a creamy-buff, hairy cap, whitish gills and short stout stem. The fungus has a cosmopolitan distribution, and grows solitarily or in scattered groups on sandy soil under or near birch.

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

Lactarius repraesentaneus, commonly known as the northern bearded milkcap, the northern milkcap, or the purple-staining bearded milkcap, is a species of fungus in the family Russulaceae. It has a northerly distribution, and is found in temperate regions of North America and Europe, associated with spruce trees. Distinguishing features of its fruit body include the large orange-yellow cap up to 18 cm (7.1 in) wide, cream to pale yellow gills, and a yellow coarsely-pitted stem that is up to 12 cm (4.7 in) long and 3 cm (1.2 in) thick. Cut fruit bodies ooze a white latex that will stain mushroom tissue lilac to purple. Several chemicals have been isolated and identified from the fruit bodies that can modify the growth of plants, and the mushroom also has antibiotic activity against Staphylococcus aureus. L. repraesentaneus is poisonous, and consumption causes stomach aches.

<i>Lactarius affinis</i> Species of mushroom

Lactarius affinis, commonly known as the kindred milk cap, is a species of milk-cap mushroom in the family Russulaceae. It is found northeastern North America, where it fruits in the summer and fall, and is common in the Great Lakes region. Its fruit bodies have medium to large, slimy dull yellow or brownish caps. Although not considered poisonous, it is unpalatable because of its highly acrid taste.

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

Lactarius fallax, commonly known as the velvety milk cap, is a species of fungus in the family Russulaceae. Found in both spruce and mixed conifer forests, it is a fairly common species in the Pacific Northwest region of North America, with a northerly range extending to Alaska. Its fruit bodies are medium-sized, with velvety, brown to blackish caps up to 3–9 cm (1.2–3.5 in) in diameter bearing a distinct pointed umbo. The caps are supported by velvety stems up to 6 cm (2.4 in) long and 1.5 cm (0.6 in) thick. The mushroom oozes a whitish latex when it is cut, and injured tissue eventually turns a dull reddish color. The eastern North American and European species Lactarius lignyotus is closely similar in appearance, but can be distinguished by its differing range.

<span class="mw-page-title-main">Lactifluus deceptivus</span> Species of fungus

Lactifluus deceptivus, commonly known as the deceiving milkcap, is a common species of fungus in the family Russulaceae. It is found throughout eastern North America on the ground in coniferous forests near hemlock or deciduous forests near oak, and in oak-dominated forests of Costa Rica. It produces large mushrooms with funnel-shaped caps reaching up to 25 cm (9.8 in) in diameter, on top of hard white stems that may reach 4–10 cm (1.6–3.9 in) long and up to 3 cm (1.2 in) thick. The gills are closely spaced together and yellowish-cream in color. When young, the cap is white in all parts, but the depressed center becomes dull brownish in age and breaks up into scales. The edge of the cap has a roll of cottony tissue that collapses as the cap expands. The surface of the stem—especially near the base—has a velvety texture. The mushroom "bleeds" a milky white acrid latex when it is cut or injured. Similar milk-cap species with which L. deceptivus might be confused include Lactifluus piperatus, L. pseudodeceptivus, L. caeruleitinctus, L. subvellereus, Lactarius arcuatus and Lactarius parvulus.

<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>Lactarius rufulus</i> Species of fungus

Lactarius rufulus, also known as the rufous candy cap or the southern candy cap, is a species of fungus in the family Russulaceae. The fruit bodies have fleshy brownish-red caps up to 10 cm (3.9 in) wide, and closely spaced pinkish-yellow gills. The stem is up to 12 cm (4.7 in) long and 3 cm (1.2 in) thick and colored similarly to the cap. The species, known only from California, Arizona, and Mexico, grows on the ground in leaf litter near oak trees. The fruit bodies resembles those of L. rufus, but L. rufulus tends to grow in clusters at a common base, rather than solitarily or in groups. A distinguishing microscopic characteristic is the near absence of large, spherical cells called sphaerocysts that are otherwise common in Lactarius species. Lactarius rufulus mushrooms are edible, and have an odor resembling maple syrup. They have been used to flavor confections and desserts.

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

Lactarius vinaceorufescens, commonly known as the yellow-staining milkcap or the yellow-latex milky, is a poisonous species of fungus in the family Russulaceae. It produces mushrooms with pinkish-cinnamon caps up to 12 cm (4.7 in) wide held by pinkish-white stems up to 7 cm (2.8 in) long. The closely spaced whitish to pinkish buff gills develop wine-red spots in age. When it is cut or injured, the mushroom oozes a white latex that rapidly turns bright sulfur-yellow. The species, common and widely distributed in North America, grows in the ground in association with conifer trees. There are several other Lactarius species that bear resemblance to L. vinaceorufescens, but most can be distinguished by differences in staining reactions, macroscopic characteristics, or habitat.

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

Lactarius pallescens is a Western North American "milk-cap" mushroom, of which the milk turns violet when the flesh is damaged. The fungi generally identified as L. pallescens are part of a complex of closely related species and varieties which have a peppery taste and are difficult to delimit definitively.
