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. [2] E.J.H. Corner transferred it to the genus Ramaria in 1950. [3]

Contents

Ramaria subbotrytis accumulates arsenic and besides arsenic species known to be found in macrofungi, such as arsenobetaine, contains a very unusual organoarsenic compound homoarsenocholine. [4] It grows in association with trees, especially conifers. [5]

The species is listed as edible by some sources. [6] [7]

Taxonomy and Phylogeny

Ramaria subbotrytis, first described as Clavaria subbotrytis by Coker in 1923, was moved to the genus Ramaria by Corner in 1950. [2] [3] A synonym of R. subbotrytis is therefore C. subbotrytis. The species has also undergone multiple other taxonomic changes, such as from the family Clavariaceae, to Ramariaceae, and most recently to the family Gomphaceae.

A recent phylogenetic study placed the genus Ramaria within the order Gomphales and the family Gomphaceae through ribosomal DNA analysis. References to unpublished analyses in the study theorize that Ramaria is monophyletic. The study places Ramaria as closely related to other hymenomycetes, including the genera Gomphus and Clavariadelphus , which all form a sister clade to another monophyletic group which includes gasteromycetes in the genera Sphaerobolus and Geastrum , and the order Phallales (represented in the study by genus Pseudocolus ). [8]

Morphology

R. subbotrytis is coral pink when immature, and fades to a creamy color except at the tips of the branches when it reaches maturity. It ranges from 7.5 to 15 centimeters tall and 5.5 to 9 centimeters wide.

The spores are produced on basidia lining the outer part of the branch tips. The basidia measure 6.5 to 9.5 micrometers, and are irregular and 4-spored. The hymenium is 55 to 65 micrometers thick with hyphae varying in size.

The spores are “nearly smooth, elliptic, cinnamon-ocraceous,” with hints of a rose color in the spore print. Coker measured the spores of one specimen between 3 to 3.7 by 7.4 to 9 micrometers, and the basidia of another specimen at 6.5 to 9.5 micrometers. He did not observe any clamp connections. [2] Corner, however, described R. subbotrytis as having clamp connections in the basidia, but not in the hyphae. [9]

The texture of R. subbotrytis is tender but not brittle. It has a short, clean, smooth, and glabrous stipe with no aborted branches. It tapers to a point on the base. Coker noted the flesh to sliver or peel when damaged. [2]

Chemical composition

Coker noted R. subbotrytis to have a “krauty” taste and odor, though only slightly. [2]

In a 2018 study, R. subbotrytis was determined through HPLC and mass spectrometry to contain several rare arsenic species, including trimethylarsoniopropanate and dimethylarsinoylacetate, which had only been found previously in marine samples. The study also noted the presence of homoarsenocholine, a compound which had never before been observed in nature. [4]

Ecological relationships

As a member of Ramaria, R. subbotrytis forms ectomycorrhizal relationships with trees. Coker found his holotype at the base of a hickory tree. [2] Ramaria are notable symbionts of conifers, especially in the Pacific Northwest, where their mycorrhiza have been studied in-depth. A study in this region on the identification of different Ramaria mycorrhiza showed that the mycorrhiza of different species in the genus are very morphologically similar and difficult to distinguish from one another. Furthermore, it characterized the mycorrhiza of Ramaria as forming mycelial mats below the soil which are made up of hyphae, mycorrhizal roots, and substrate. [5]

R. subbotrytis has been described to be distributed throughout North America and Europe. The social network iNaturalist displays observations (both research grade and unverified) in both regions. [10] It has been described in scientific literature as appearing in Slovakia, the Czech Republic, [4] the Urals of Russia, [11] the Jilotzingo region of Mexico, [12] throughout the Iberian Peninsula, [13] and throughout the United States and Canada, making the species widely geographically distributed. It was described in 2011 in Andalucía, Spain for the first time. [14]

A study conducted about the mesofauna associated with different fungi in the province of Santa Ana Jilotzingo, Mexico found that collembolans and oribatid mites are the most prominent inhabitants of R. subbotrytis sporomes. Analysis of the mites’ and collembolans’ gut contents suggested a symbiotic relationship between the fungus and the arthropods, possibly involving spore dispersal due to the presence of spores in their digestive tracts. [12]

Edibility and traditional use

Many Ramaria species are used in traditional medicinal practices, and are traded commercially for these purposes or as food sources. [15] Some sources consider Ramaria subbotrytis to be edible, [6] though others list it as “unknown” and cite its known arsenic contents. [4]

Similar species

Coker lists several morphologically similar species to R. subbotrytis, including R. botrytis , R. conjunctipes var. odora, and R. formosa . It is distinguished from R. botrytis because R. subbotrytis has much darker spores and lacks red branch tips in its immature stages. R. conjunctipes var. odora is distinguishable by its more brittle, solid flesh, different odor, deeper colored flesh with tips that are the same color as the rest of the fruiting body, and a wider and less compound base. It differs from R. formosa which is much more brittle and has yellow tips in immature stages, as well as a deeper pink color and narrower and smoother cinnamon colored spores than R. subbotrytis.

Coker also described R. subbotrytis var. intermedia, which is an intermediate species between R. botrytis and R. subbotrytis. It has a similar body and base morphology to R. botrytis, but the same spore color and shape as R. subbotrytis. For that reason, Coker chose to classify it as a variant of R. subbotrytis. [2]

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

Ramaria formosa, commonly known as the salmon coral, beautiful clavaria, handsome clavaria, yellow-tipped- or pink coral fungus, is a coral fungus found in Europe. It is widely held to be mildly poisonous if consumed, giving rise to acute gastrointestinal symptoms of nausea, vomiting, diarrhea and colicky pain. It is a pinkish, much-branched coral-shape reaching some 20 cm (8 in) high. Similar forms collected in North America are now considered to represent a different species than the European Ramaria formosa.

<i>Ramaria</i> Genus of fungi

The genus Ramaria comprises approximately 200 species of coral fungi. 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.

<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.

<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>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>Clavariadelphus ligula</i> Species of fungus

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

Ramaria stricta, commonly known as the strict-branch coral 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 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>Ramaria flavosaponaria</i> Species of fungus

Ramaria flavosaponaria is a species of coral fungus in the family Gomphaceae. It is found in the mountains of eastern North America from Georgia and Tennessee to Nova Scotia.

Phaeoclavulina murrillii is a coral fungus that is widely distributed in the southeastern United States. It has also been found as far North in the United States as Michigan, and in Spain.
