Identifying the Russula family (in most cases) is pretty easy, they are very common, very colourful and lots of them are edible!  According to MycoBank, the European species Russula chloroides is synonymous with R. brevipes, although Index Fungorum and other sources consider them distinct species.  It is classified in the subsection Lactaroideae, a grouping of similar Russula species characterized by having whitish to pale yellow fruit bodies, compact and hard flesh, abundant lamellulae (short gills), and the absence of clamp connections. Russula brevipes: 3 epithelial element, 4 macrocystidia and basidia, 5-6 basidiospores Russula luteotacta 7 fruit bodies in habit, 8 showing gills and stipe Figures - uploaded by Ram Keerti Verma , Fruit bodies are commonly parasitized by the ascomycete Hypomyces lactifluorum, transforming them into an edible known as a lobster mushroom. It is the product resulting of the infection, most commonly of Russula brevipes by Hypomyces lactifluorum.  Common names used to refer to the mushroom include short-stemmed russula, short-stalked white russula, and stubby brittlegill. There are, of course, many exceptions to the drop-kick rule (such as the tough Russula brevipes and the very dense Russula compacta group), but it's fun to try anyway, especially in frustration in trying to identify most Russula species. Bidartondo, M. I. Russula brevipes.  The mushrooms are usually found as "shrumps"—low, partially emerged mounds on the forest floor, and have often been partially consumed by mammals such as rodents or deer. Toxicity Mild-tasting russulas are often eaten.  The mushrooms are suitable for pickling due to their crisp texture. Short-stalked russula partly hidden under forest litter, photograph by David Carmean.  The spore print is white to light cream. Russula brevipes is a species of mushroom commonly known as the short-stemmed russula or the stubby brittlegill. All strains were maintained on Malt extract … Thus, for example, b X b = Russula brevipes as maternal fungus X R brevipes as the fungus which initiated germination. 1) R. brevipes has an acrid-tasting variety! Habitat: In all kinds of forests, both with oaks (Quercus spp.) Russula brevipes is a non-descript edible species that tends to assume the flavors of meats and sauces it is cooked with. , Russula brevipes is a non-descript edible species that tends to assume the flavors of meats and sauces it is cooked with. Avoid eating acrid/hot specimens, which may be cascade russulas rather than short-stalked russulas. The colour is white to cream, often with brown stains. Siegel and Schwartz 3 warn that some forms of short-stalked russula taste good while others are 'down right awful'. In cooking, all varieties of edible russula are used in boiled, fried, salted and pickled forms.  The Pacific Northwest species Russula cascadensis also resembles R. brevipes, but has an acrid taste and smaller fruit bodies. This study undertook quantitative polymerase chain reaction analysis of tissues sampled at different infection stages, to investigate R. brevipes/H. Geographical distribution: The species in a broad sense has worldwide distribution. This common russula is initially white, but it soon develops tan, brownish, or flat-out orangish brown colors—though it can also remain fairly pale overall. Lactarius piperatus has a hot, peppery flavour that makes it inedible for most of us but the parasitic mold does help neutralize the flavour and this combination can make its way to the dinner table. Amanita aprica. Gills: Very crowded, with many short gills interspersed among the long gills, decurrent onto the stem, white. Under pines or in mixed woods. , It is a common ectomycorrhizal fungus associated with several hosts across temperate forest ecosystems.  In western North America, where the mushroom is quite common, it is encountered most frequently in late autumn.  Some of these compounds have been isolated and chemically characterized from Russula brevipes: russulactarorufin, lactarorufin-A, and 24-ethyl-cholesta-7,22E-diene-3β,5α,6β-triol. , "Although attractive when clean and crisp, this harmless, prolific mushroom is constantly maligned because it mimics prized edibles such as the white. Russula flavida [ Basidiomycetes > Russulales > Russulaceae > Russula.  In a 2012 publication, mycologist Mike Davis and colleagues suggest that western North American Russula brevipes comprise a complex of at least four distinct species.  The fungus has been reported in Pakistan's Himalayan moist temperate forests associated with Pinus wallichiana. The fungus grows in a mycorrhizal association with trees from several genera, including fir, spruce, Douglas-fir, and hemlock. These mushrooms are also used as a filling for pies. . Ring or veil: None. There are no cystidia on the cap (pileocystidia). Poison Control: Funnel-shaped, large, white brittle caps C On mainland Europe this brittlegill occurs from Scandinavia down to the Mediterranean countries. Russula brevipesis one of the most common Russulaspecies on the west coast, and is easily identified by its stature, large size, and white coloration which does not stain when handled.  Fruit bodies grow singly or in groups; fruiting season occurs from summer to autumn. Spores are roughly spherical, and have a network-like surface dotted with warts. It is widespread in North America, and was reported from Pakistan in 2006. A post by my talented student Ben Hoffman, who took my Mushrooms class in 2013.  In contrast, there was little genetic differentiation observed between populations sampled from a smaller area (less than approximately 1000 meters). A good test for Russulas is the taste test, if a tiny amount is placed on the tongue and chewed a burn like chilli means the mushroom is poisonous, a pleasant mushroomy taste means it is edible. , The variant R. brevipes var. The fungus grows in a mycorrhizal association with trees from several genera, including fir, spruce, Douglas-fir, and hemlock. Summary 4 Russula brevipes is a species of mushroom commonly known as the short-stemmed russula.It is edible, although its quality is improved once parasitised by the ascomycete fungus Hypomyces lactifluorum, transforming it into an edible known as a lobster mushroom.. Bioactive compounds 5 Sesquiterpene lactones are a diverse group of biologically active compounds that are … Short-stalked russula2 photograph by Alexander H. Smith with permission from the Denver Botanical Garden. Odour: Mild. Six wild edible mushroom cultures namely Russula lepida, Russula brevipes, Russula nigricans, Pleurotus sajor-caju, Lentinus tuberregium and Calocybe indica were used for the study of biomass production in different medium. They become more palatable once parasitized by the ascomycete fungus Hypomyces lactifluorum, a bright orange mold that covers the fruit body and transforms them into lobster mushrooms. Other related Russula species with a similar range of spore ornamentation heights include Russula delica, R. romagnesiana, and R. Luckily for the mushroom hunter, H. lactifluorum is either an exceptional taxonomist or produces compounds that neutralize the host mushroom’s toxins. The gills are narrow and thin, decurrent in attachment, nearly white when young but becoming pale yellow to buff with age, and sometimes forked near the stipe. The resulting mushroom is called a Hypomyces lactifluorum (or Lobster) and it is them a very desirable edible. It is initially white but develops yellowish-brownish discolorations with age. , Sesquiterpene lactones are a diverse group of biologically active compounds that are being investigated for their antiinflammatory and antitumor activities. The specific epithet brevipes is derived from the Latin words brevis "short" and pes "foot", hence "short-footed". The gills typically bruise brownish, and the stem is often fairly short in proportion to the cap ( brevipes means "short-stemmed"), and … , Studies have demonstrated that geographically separated R. brevipes populations (globally and continentally) develop significant genetic differentiation, suggesting that gene flow between these populations is small. Fairly common and widespread in woodland that contains broadleaf trees, Russula delica occurs throughout Britain and Ireland but is reported more frequently from regions of alkaline or neutral soil. Although edible, Russula brevipes mushrooms have a bland or bitter flavor. Robert Shaffer summarized the taxonomic conundrum in 1964: Russula delica is a species that everybody knows, so to speak, but the evidence indicates that R. delica sensu Fries (1838) is not R. delica sensu Singer (1938), which in turn is not R. delica sensu Kühner and Romagnesi (1953)… It is best to use R. brevipes for the North American collections which most authors but not Kühner and Romagnesi (1953), call R. delica. It is a edible by not choice. Russula brevipes, with their low stature and brownish scales, make for especially deceptive and frustrating pine mushroom lookalikes. 'Stubby Short-footed Russula'. Russula brevipes is a North American species closely related to Russula delica in a group of Russula species resembling members of Lactarius, with white-to-yellow cap colors staining sordid yellow-to-umber in age, whose flesh is compact and unchanging in color, with abundant lamellulae, and having a blue-green reaction to the application of iron salts. Russula brevipes var. ), and Douglas fir (Pseudotsuga menziesii), often only visible as a raised piece of forest floor; ectomycorrhizal4.  The cap cuticle is arranged in the form of a cutis (characterized by hyphae that run parallel to the cap surface) comprising interwoven hyphae with rounded tips. Almost white spores . Cap: 7â30 cm in diameter. It is one of several Russula species harvested in the wild from Mexico's Izta-Popo Zoquiapan National Park and sold in local markets in nearby Ozumba. Russula brevipes Peck., is widely distributed t hroughout North America, and mai nly associated with species of Abies, Picea, Tsuga and Pseudosuga (Stani s, 1979; Kraiger et al , 1995). Russula brevipes is a known edible, so it's not too surprising that the complex of these two species is edible. Amanita silvicola. Hypomyces luteovirens (also  The nomenclatural database Index Fungorum does not consider these varieties to have independent taxonomical significance. The surface of the mushroom becomes bright orange or reddish-purple and unpalatable host mushrooms are transformed into a delicious edible. The gills on the cap underside are closely spaced and sometimes have a faint bluish tint. Fries's concept of R. delica included: a white fruit body that did not change color; a smooth, shiny cap; and thin, widely spaced gills. lactifluorum It is widespread in North America, and was reported from Pakistan in 2006. The Russulas are often overlooked as as edible option in the UK. Similar to R. brevipes in overall morphology, it has somewhat larger spores (9–12 by 7–8.5 µm) with a surface ornamentation featuring prominent warts interconnected by a zebra-like patterns of ridges. Considered edible. The only two species that we know are infected by the lobster mushroom fungus in North America are Russula brevipes and Lactifluus (Lactarius) piperatus. The lecithin contained in the composition prevents cholesterol deposition. Typical hosts include trees in the genera Abies, Picea, Pseudotsuga, and Tsuga. Edible, but usually mediocre. The fungus grows in a mycorrhizal association with trees from several genera, including fir, spruce, Douglas-fir, and hemlock. pseudodelica.. Poison Centres provide free, expert medical advice 24 hours a day, seven days a week.  R. brevipes var. acrior Shaffer has a subtle green shading at the stipe apex and on the gills. Fortunately, Russula brevipes are an edible, although unappetizing mushroom. "Biodiversity of mushrooms and ectomycorrhizas. To add to the confusion, Rolf Singer and later Robert Kühner and Henri Romagnesi described other species they named Russula delica. Russula brevipes is also known as the short stemmed russula.

''Russula brevipes'' is a species of mushroom commonly known as the short-stemmed russula or the stubby brittlegill. brevipes. British Columbia: 604-682-5050 or 1-800-567-8911. Russula brevipes creates a choice edible and according to Tom Volk’s can give your lobster chowder a boost.  The milk-cap mushroom Lactifluus piperatus can be distinguished from R. brevipes by the production of latex when the mushroom tissue is cut or injured. Today's mushroom, Russula brevipes is one of the most common mushrooms this time of year in this area. This fungus is edible but is best when parasitized by the ascomycete (a fungus like yeast) Hypomyces lactifluorum. Though in other European countries some are collected regularly for eating, and I … The mushrooms are suitable for pickling due to their crisp texture. Neither the bruised stem nor the sliced flesh turns grayish, and the taste is mild. Taste not distinctive. Spores: 8-10 x 6.5-9 Âµm, with scattered warts. They found that the infected and edible lobster mushroom mostly contains the DNA of the parasitic fungus with only trace amounts of … I have found no records of this species from North America, but a very similar brittlegill Russula brevipesis common across much of the US… There has been considerable confusion in the literature over the naming of Russula brevipes. Treatment: Contact your regional Poison Control Centre if you or someone you know is ill after eating russulas. Taste: Mild to acrid. In general, members of the genus Russula are fairly large, gilled with a white underside and a cap that most often is a variation of white or red. Russula's are very common, and infamous for being very hard to positively identify. megaspora has spores measuring 9–14 by 8–12 µm. The cap starts out rounded with a central depression, and becomes more vase-like depressed with a wavy edge. Russula brevipes is a species of mushroom commonly known as the short-stemmed russula or the stubby brittlegill. In reality the mushroom originally was a Russula brevipes, a commonly white russula found in the Pacific Northwest. 'Short-footed Russula'. The mold attacks and grows on Short-stalked White Russula (Russula brevipes) and Peppery Milky (Lactarius piperatus) transforming and changing their appearance and taste.  It is one of several Russula species harvested in the wild from Mexico's Izta-Popo Zoquiapan National Park and sold in local markets in nearby Ozumba. Like var. To speculate, different species within the complex may differ in flavour.  R. angustispora is quite similar to R. brevipes, but has narrower spores measuring 6.5–8.5 by 4.5–5 µm, and it does not have the pale greenish band that sometimes develops in the latter species. This beautiful mushroom is fairly common in the oak forests of eastern North America. Edible russula is one of the most common mushrooms in our latitudes.
