Rhizomarasmius undatus (syn. Marasmius undatus) is a small mushroom which grows on fern rhizomes. [2] [3] [1]
The species can be described as follows: [2] [3] [4]
The species epithet undatus, meaning "wavy", is the past participle of the Latin verb "undo" (= "I undulate"). [5]
This species was originally described in 1836 as Agaricus undatus by Miles Joseph Berkeley. As it happened, in 1838 the famous mycologist Elias Magnus Fries defined a completely different mushroom (now Entoloma undatum) under the same name, but due to the nomenclatural rules of precedence, that definition is illegitimate. This was confirmed when in 1849 Fries renamed Berkeley's fungus with the combination Marasmius undatus, a name which was current for more than a century. Then in 2000 it was one of the two initial species with which R. H. Petersen created the new genus Rhizomarasmius , the other one being the type species R. pyrrhocephalus. [1] [6]
This mushroom grows on rhizomes of bracken (Pteridium aquilinum) and probably other ferns. [2] [3] It is widespread but rare in northern and western Europe and has been reported from North Africa, North America, and the Altai Mountains. [2] [4] [7]
Marasmius oreades, also known as the fairy ring mushroom, fairy ring champignon or Scotch bonnet, is a mushroom native to North America and Europe. Its common names can cause some confusion, as many other mushrooms grow in fairy rings, such as the edible Agaricus campestris and the poisonous Chlorophyllum molybdites.
Mycetinis alliaceus, commonly known as the garlic parachute, is one of the larger mushrooms formerly in the genus Marasmius, having a beige cap of up to 4 cm and a long tough slender stipe. It emanates a strong smell of garlic, and this is the significance of the Latin species name, alliaceus. It is distributed throughout Europe, being fairly common in some areas and quite rare in others.
Hygrophorus agathosmus, commonly known as the gray almond waxy cap or the almond woodwax, is a species of fungus in the family Hygrophoraceae. It was first described by Elias Magnus Fries in 1815; Fries gave it its current name in 1838. A widespread species, it is distributed in the United States, Europe, Africa, and India, and is found growing under spruce and pine in mixed forests. The fruit bodies are characterized by a light grayish cap that measures up to 8 cm (3.1 in) in diameter, waxy gills, a dry stem, and the distinct odor of bitter almonds. An edible but bland-tasting mushroom, extracts of the fruit bodies have been shown in laboratory tests to have antimicrobial activity against various bacteria that are pathogenic to humans.
Marasmius rotula is a common species of agaric fungus in the family Marasmiaceae. Widespread in the Northern Hemisphere, it is commonly known variously as the pinwheel mushroom, the pinwheel marasmius, the little wheel, the collared parachute, or the horse hair fungus. The type species of the genus Marasmius, M. rotula was first described scientifically in 1772 by mycologist Giovanni Antonio Scopoli and assigned its current name in 1838 by Elias Fries.
Cortinarius traganus, also known as the gassy webcap or lilac conifer cortinarius, is a basidiomycete mushroom of the genus Cortinarius. The mushrooms are characterized by their lilac color, the rusty-brown gills and spores, and rusty-brown flesh in the stem.
Cortinarius anomalus, also known as the variable webcap, is a basidiomycete fungus of the genus Cortinarius. It produces a medium-sized mushroom with a grayish-brown cap up to 5 cm (2 in) wide, gray-violet gills and a whitish stem with pale yellow belts below. The mushroom grows solitarily or in scattered groups on the ground in deciduous and coniferous forests. It is found throughout the temperate zone of the northern hemisphere.
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.
Amanita ravenelii, commonly known as the pinecone lepidella, is a species of fungus in the family Amanitaceae. The whitish fruit bodies are medium to large, with caps up to 17 centimetres wide, and stems up to 25 cm (10 in) long. The cap surface has large warts and the stem has a scaly, bulbous base. The mushrooms have a unique chlorine like odor.
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.
Tylopilus alboater, called the black velvet bolete, by some, is a bolete fungus in the family Boletaceae. The species is found in North America east of the Rocky Mountains, and in eastern Asia, including China, Japan, Taiwan, and Thailand. A mycorrhizal species, it grows solitarily, scattered, or in groups on the ground usually under deciduous trees, particularly oak, although it has been recorded from deciduous, coniferous, and mixed forests.
Marasmiellus hapuuarum is a species of agaric fungus in the family Marasmiaceae. Formally described in 2011, it is known only from Hawaiian montane wet forests where it grows on aging hāpuʻu plants. The fungus produces small pinkish-buff fruit bodies up to 0.6 cm (0.24 in) in diameter, with distantly spaced narrow gills.
Collybiopsis peronata, also known as wood woolly-foot, is a species of gilled mushroom which is common in European woods.
Mycetinis scorodonius is one of the garlic-scented mushrooms formerly in the genus Marasmius, having a beige cap of up to 3 cm and a tough slender stipe.
Mycetinis querceus is one of the garlic-scented mushrooms formerly in the genus Marasmius. It has a reddish brown stipe, and usually grows on fallen oak leaves.
Mycetinis kallioneus is a mushroom formerly in the genus Marasmius, which grows with dwarf shrubs and flowering plants in an arctic environment where the ground is covered by snow for much of the year.
Rhizomarasmius epidryas is one of a group of mushrooms formerly in the genus Marasmius. It grows amongst dwarf shrubs of the genus Dryas in arctic or high mountain environments.
Rhizomarasmius setosus is a tiny whitish mushroom having a distinctive hairy stem. It has been given the vernacular name "Beechleaf Parachute".
Infundibulicybe gibba, and commonly known as the common funnel or funnel cap, is a species of gilled mushroom which is common in European woods.
Marasmius cohaerens is a species of gilled mushroom which is fairly common in European woods.
Marasmius wynneae is a species of gilled mushroom found in European woods.
