(Pers.: Fr.) Ricken (1918)

The genus Ramaria comprises approximately 200 species of coral fungi. [1] Several, such as Ramaria flava , are edible and picked in Europe, though they are easily confused with several mildly poisonous species capable of causing nausea, vomiting, and diarrhea; these include R. formosa and R. pallida . Three Ramaria species have been demonstrated to contain a very unusual organoarsenic compound homoarsenocholine. [2]

Etymology

The genus name is derived from Latin rāmus meaning branch. [3]

Description

Basidiocarps may range in color from bright yellow, red, pink, or orange, to purple, white, and shades of tan. Color changes after bruising occur in some species.

The spores of Ramaria species are yellow-brown to rusty-brown in mass deposit and range from smooth to warted to echinulate or striate; spore size may range considerably, and ornamentation, when present, is cyanophilous.

Classification

Hjomsköld was the first to introduce the name Ramaria in 1790. [4] Persoon later described R. botrytis , and placed it in the genus Clavaria. [5] Fries sanctioned the name Clavaria in 1821 and treated Ramaria as a section of Clavaria. In 1933, Donk elevated the name Ramaria to its current generic status by recognizing Bonorden's use of the name Ramaria. [5] [6] Currently, Ramaria is placed in the Gomphaceae, [7] although some older sources still classify it in the Ramariaceae. Ramaria has been further subdivided into four subgenera based on differences in spore ornamentation, substrate habitat, clamps, and basidiocarp appearance. [5]

Phylogenetic analyses has shown that Ramaria is not monophyletic, and that the characteristic coralloid shape has likely evolved several times from different ancestors. [8]

<span class="mw-page-title-main">Clavariaceae</span> Family of fungi

The Clavariaceae are a family of fungi in the order Agaricales. Originally the family contained most of the clavarioid fungi, but in its current sense is more restricted, albeit with a greater diversity of basidiocarp forms. Basidiocarps are variously clavarioid or agaricoid (mushroom-shaped), less commonly corticioid or hydnoid.

<i>Ramaria formosa</i> Species of fungus

Ramaria formosa, commonly known as the pinkish coral mushroom, salmon coral, beautiful clavaria, handsome clavaria, yellow-tipped- or pink coral fungus, is a coral fungus found in Europe. Similar forms collected in North America are considered to represent a different species.

<i>Ramariopsis</i> Genus of fungi

Ramariopsis is a genus of coral fungi in the family Clavariaceae. The genus has a collectively widespread distribution and contains about 40 species. The name means 'having the appearance of Ramaria'.

<i>Ramariopsis kunzei</i> Species of fungus

Ramariopsis kunzei is an edible species of coral fungi in the family Clavariaceae, and the type species of the genus Ramariopsis. It is commonly known as white coral because of the branched structure of the fruit bodies that resemble marine coral. The fruit bodies are up to 5 cm (2.0 in) tall by 4 cm (1.6 in) wide, with numerous branches originating from a short rudimentary stem. The branches are one to two millimeters thick, smooth, and white, sometimes with yellowish tips in age. Ramariopsis kunzei has a widespread distribution, and is found in North America, Europe, Asia, and Australia.

<i>Ramaria botrytis</i> Species of coral fungus in the family Gomphaceae

Ramaria botrytis, commonly known as the clustered coral, the pink-tipped coral mushroom, or the cauliflower coral, is an edible species of coral fungus in the family Gomphaceae. Its robust fruit body can grow up to 15 cm (6 in) in diameter and 20 cm (8 in) tall, and resembles some marine coral. Its dense branches, which originate from a stout, massive base, are swollen at the tips and divided into several small branchlets. The branches are initially whitish but age to buff or tan, with tips that are pink to reddish. The flesh is thick and white. The spores, yellowish in deposit, are ellipsoid, feature longitudinal striations, and measure about 13.8 by 4.7 micrometers.

<i>Mucronella</i> Genus of fungi

Mucronella is a genus of fungi in the family Clavariaceae. Species in the genus resemble awl-shaped teeth that grow in groups without a common subiculum.

<i>Clavaria</i> Genus of fungi

Clavaria is a genus of fungi in the family Clavariaceae. Species of Clavaria produce basidiocarps that are either cylindrical to club-shaped or branched and coral-like. They are often grouped with similar-looking species from other genera, when they are collectively known as the clavarioid fungi. All Clavaria species are terrestrial and most are believed to be saprotrophic. In Europe, they are typical of old, mossy, unimproved grassland. In North America and elsewhere, they are more commonly found in woodlands.

<span class="mw-page-title-main">Clavarioid fungi</span> Group of fungi

The clavarioid fungi are a group of fungi in the Basidiomycota typically having erect, simple or branched basidiocarps that are formed on the ground, on decaying vegetation, or on dead wood. They are colloquially called club fungi and coral fungi.

<i>Clavaria fragilis</i> Species of fungus

Clavaria fragilis, commonly known as fairy fingers, white worm coral, or white spindles, is a species of fungus in the family Clavariaceae. It is synonymous with Clavaria vermicularis. The fungus is the type species of the genus Clavaria and is a typical member of the clavarioid or club fungi. It produces tubular, unbranched, white basidiocarps that typically grow in clusters. The fruit bodies can reach dimensions of 15 cm (5.9 in) tall by 0.5 cm (0.2 in) thick. Clavaria fragilis is a saprobic species, growing in woodland litter or in old, unimproved grassland. It is widespread throughout temperate regions in the Northern Hemisphere, but has also been reported from Australia and South Africa. The fungus is edible, but insubstantial and flavorless. There are several other small white coral-like fungi with which C. fragilis may be confused.

<i>Clavaria zollingeri</i> Species of fungus

Clavaria zollingeri, commonly known as the violet coral or the magenta coral, is a widely distributed species of fungus. It produces striking tubular, purple to pinkish-violet fruit bodies that grow up to 10 cm (3.9 in) tall and 7 cm (2.8 in) wide. The extreme tips of the fragile, slender branches are usually rounded and brownish. A typical member of the clavarioid or club fungi, Clavaria zollingeri is saprobic, and so derives nutrients by breaking down organic matter. The fruit bodies are typically found growing on the ground in woodland litter, or in grasslands. Variations in branching and color can often be used to distinguish C. zollingeri from similarly colored coral fungi such as Alloclavaria purpurea and Clavulina amethystina, although microscopy is required to reliably identify the latter species.

<i>Phaeoclavulina abietina</i> Species of fungus

Phaeoclavulina abietina, commonly known as the green-staining coral, is a coral mushroom in the family Gomphaceae. It is characterized by the green staining reaction it develops in response to bruising or injury.

<i>Ramaria stricta</i> Species of fungus

Ramaria stricta, commonly known as the strict-branch coral or strict coral mushroom, is a coral fungus of the genus Ramaria. It has a cosmopolitan distribution, and grows on dead wood, stumps, trunks, and branches of both deciduous and coniferous trees. Its fruit body is up to 10 cm tall, made of multiple slender, compact, and vertical parallel branches. Its color is typically light tan to vinaceous-brown. All parts of the mushroom will bruise when handled. There are several lookalike corals that can usually be distinguished from R. stricta by differences in coloration, bruising reaction, or microscopic features. The fungus is inedible due to its unpleasant odor and bitter taste.

<i>Ramaria cokeri</i> Species of fungus

Ramaria cokeri is a coral mushroom in the family Gomphaceae. It was described in 1976 from the Appalachian Mountains in the United States. Some authors have proposed to place the species in a separate genus Phaeoclavulina based on molecular analyses, but this was explicitly rejected in a subsequent publication due to the resulting morphological variability of the resulting genus.

<i>Ramaria botrytoides</i> Species of fungus

Ramaria botrytoides is a species of coral fungus in the family Gomphaceae. First described by American mycologist Charles Horton Peck in 1905 as Clavaria botryoides, it was transferred to the genus Ramaria in 1950 by E.J.H. Corner. Found in the eastern United States, it resembles Ramaria botrytis, but can be most reliably distinguished from that species by the lack of longitudinal striations in its spores.

<i>Ramaria subbotrytis</i> Species of fungus

Ramaria subbotrytis is a species of coral fungus in the family Gomphaceae. It was previously classified in the family Ramariaceae, and before that in the genus Clavaria, family Clavariaceae. It was originally described as Clavaria subbotrytis by William Chambers Coker in 1923 from collections made in North Carolina. E.J.H. Corner transferred it to the genus Ramaria in 1950.

<i>Ramaria magnipes</i> Species of fungus

Ramaria magnipes is a coral fungus in the family Gomphaceae. It is found in western North America, where it fruits on the ground in mixed forests.

<i>Ramaria flavescens</i> Species of fungus

Ramaria flavescens is a species of coral fungus in the family Gomphaceae. It was first described as Clavaria flavescens by Jacob Christian Schäffer in 1762; American mycologist Ron Peterson transferred it to the genus Ramaria in 1974. The IUCN Red List labels this species as Critically Endangered in Denmark and as Data Deficient in the Czech Republic.

<i>Ramaria gracilis</i> Species of fungus

Ramaria gracilis is a species of coral fungus in the family Gomphaceae.

<i>Ramaria myceliosa</i> Species of fungus

Ramaria myceliosa is a species of coral fungus in the family Gomphaceae. Found in North America, it was originally described by Charles Horton Peck in 1904 with the name Clavaria myceliosa. The type was collected by botanist Edwin Bingham Copeland in the mountains near Stanford University in California. E.J.H. Corner transferred it to the genus Ramaria in 1950. Giachini and colleagues proposed that Ramaria myceliosa is the same species as the European Phaeoclavulina curta, but did not provide molecular evidence to support their suggested synonymy. In a recent (2014) publication on California fungi, the authors propose the transfer of Ramaria myceliosa to the genus Phaeoclavulina, but as of January 2016, this transfer has not been accepted by either MycoBank or Index Fungorum.

<i>Clavulinopsis corniculata</i> Species of fungus

Clavulinopsis corniculata is a clavarioid fungus in the family Clavariaceae. In the UK, it has the recommended English name of meadow coral. It forms branched, cylindrical, ochre fruit bodies that grow on the ground in agriculturally unimproved grassland or in woodland litter. It was originally described from Germany and is part of a species complex as yet unresolved.
