Contents

Taxonomy

The species was first described by the German naturalist Jacob Christian Schaeffer in 1774 as Clavaria ligula. [2] It was first placed in Clavariadelphus by Marinus Anton Donk in 1933. [3] Clavaria ophioglossoides, described by August Batsch in 1783, [4] is considered a synonym. [5]

The fungus is commonly known as the "strap coral". [6] The specific epithet ligula is derived from the Latin word for "shoestring". [7]

Description

Typical growth habit Clavariadelphus ligula 47695.jpg
Typical growth habit

The club portion of the fruit body is pale yellow, whitish sharp, straight, and stiff hairs at its base. The surface is dull, and does not have hairs. It is smooth at first then later becomes somewhat wrinkled. It is club-shaped to spoon-shaped, and up to 12 cm (4.7 in) tall by 2 cm (0.8 in) wide at the thickest part. The stipe is not distinct except for the hairs at the base. The flesh is whitish, and does not change color with bruising. It is somewhat spongy in the upper part, but firm below. The flesh has no odor, and its taste is slightly bitter. The surface tissue turns green upon the application of a solution of ferric sulphate, and yellow with a dilute solution of potassium hydroxide. [8]

The spores are pale yellowish orange ("light buff") in print. Additional features may be discerned using light microscopy: they are smooth, narrowly ellipsoid, and measure 8–15 by 3–6  μm. The hyphae are monomitic, and clamp connections are present. Cystidia are absent. [8]

One field guide lists the species as edible, [9] while another says it is inedible. [10]

Similar species

Clavariadelphus sachalinensis is macroscopically identical from C. ligula, and can be distinguished only by its larger spores, measuring 16–24 by 4–6  μm, and longer basidia. [8] However, intermediate forms are often found, and they may represent the same species. [11] Clavaria flavipes is another similar species, but in addition to being smaller and more pale yellow than Clavariadelphus ligula, it also has broader spores. [12]

Habitat and distribution

The fruit bodies of Clavariadelphus ligula grow gregariously (closely scattered over small areas) on the ground, in forest duff. They are widespread and common in coniferous forests, fruiting in the summer and fall. [8]

<i>Spathularia flavida</i> Species of fungus

Spathularia flavida, commonly known as the yellow earth tongue, the yellow fan, or the fairy fan, is an ascomycete fungus found in coniferous forests of Asia, Europe and North America. It produces a small, fan- or spoon-shaped fruit body with a flat, wavy or lobed cream to yellow colored "head" raised on a white to cream stalk. The height is usually approximately 2–5 cm, and up to 8 cm. The fungus fruits on the ground in mosses, forest duff or humus, and fruit bodies may occur singly, in large groups, or in fairy rings. The spores produced by the fungus are needle-like, and up to 95 μm long. Several varieties have been described that differ largely in their microscopic characteristics. S. flavida has been described by authorities variously as inedible, of unknown edibility, or edible but tough.

<i>Paragyromitra infula</i> Species of fungus

Paragyromitra infula, commonly known as the hooded false morel or the elfin saddle, is a species of fungus in the family Discinaceae. The dark reddish-brown caps of the fruit bodies develop a characteristic saddle-shape in maturity, and the ends of both saddle lobes are drawn out to sharp tips that project above the level of the fruit body. The stipe is white or flushed pale brown, smooth on the outside, but hollow with some chambers inside.

<i>Hydnellum aurantiacum</i> Species of fungus

Hydnellum aurantiacum is an inedible fungus, commonly known as the orange spine or orange hydnellum for its reddish orange or rusty red colored fruit bodies. Like other tooth fungi, it bears a layer of spines rather than gills on the underside of the cap. Due to substantial declines in sightings, this species is listed as critically endangered in the United Kingdom.

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

Lactarius vietus is a species of fungus in the family Russulaceae, first described by Elias Magnus Fries. It produces moderately sized and brittle mushrooms, which grow on the forest floor or on rotting wood. The flattened-convex cap can vary in shape, sometimes forming the shape of a wide funnel. It is typically grey, but the colour varies. The species has crowded, light-coloured gills, which produce white milk. The spore print is typically whitish, but also varies considerably. The mushrooms typically have a strong, acrid taste and have been described as inedible, but other authors have described them as consumable after boiling. L. vietus feeds by forming an ectomycorrhizal relationship with surrounding trees, and it favours birch. It grows in autumn months and is fairly common in Europe, North America and eastern Asia.

<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>Mycena acicula</i> Species of fungus in the family Mycenaceae

Mycena acicula, commonly known as the orange bonnet, or the coral spring Mycena, is a species of fungus in the family Mycenaceae. It is found in Asia, the Caribbean, North America and Europe. The fruit bodies, or mushrooms, of the fungus grow on dead twigs and other woody debris of forest floors, especially along streams and other wet places. They have small orange-red caps, up to 1 cm (0.4 in) in diameter, held by slender yellowish stems up to 6 cm (2.4 in) long. The gills are pale yellow with a whitish edge. Several other Mycena species look similar, but may be distinguished by differences in size and/or microscopic characteristics. M. acicula is considered inedible because of its small size.

<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.

<i>Pholiota flammans</i> Species of fungus

Pholiota flammans, commonly known as the yellow pholiota, the flaming Pholiota, or the flame scalecap, is a basidiomycete agaric mushroom of the genus Pholiota. Its fruit body is golden-yellow in color throughout, while its cap and stem are covered in sharp scales. As it is a saprobic fungus, the fruit bodies typically appear in clusters on the stumps of dead coniferous trees. P. flammans is distributed throughout Europe, North America, and Asia in boreal and temperate regions. Its edibility has not been clarified.

<i>Caloboletus rubripes</i> Species of fungus

Caloboletus rubripes, commonly known as the red-stipe bolete or the red-stemmed bitter bolete, is a mushroom in the family Boletaceae. It was known as Boletus rubripes until 2014. Fruit bodies (mushrooms) are robust, with caps up to 18 cm in diameter, atop thick stipes 5–12 cm long. Mushrooms are non-toxic, but is so bitter as to be inedible. The mushroom flesh has a very strong bluing reaction when cut or damaged and forms mycorrhizal relationships, primarily with conifers. It can be differentiated from similar boletes by its cap color and non-reticulate stipe.

<i>Clavariadelphus truncatus</i> Species of mushroom

Clavariadelphus truncatus, commonly known as the truncate club coral, truncated club, or club coral, is a species of mushroom. It is a member of the basidiomycete fungi family Gomphaceae.

<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>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>Resupinatus applicatus</i> Species of fungus

Resupinatus applicatus, commonly known as the smoked oysterling or the black jelly oyster, is a species of fungus in the family Tricholomataceae, and the type species of the genus Resupinatus. First described in 1786 as Agaricus applicatus by August Johann Georg Karl Batsch, it was transferred to Resupinatus by Samuel Frederick Gray in 1821.

<i>Thelephora palmata</i> Species of clavarioid fungus

Thelephora palmata commonly known as the fetid false coral or stinking earthfan, is a species of clavarioid fungus in the family Thelephoraceae. The fruit bodies are leathery and coral-like, with branches that are narrow at the base before widening out like a fan and splitting into numerous flattened prongs. The wedge-like tips are whitish when young, but darken as the fungus matures. The common names of the fungus refers to its pungent odor, likened to fetid garlic. A widely distributed but uncommon species, it is found in Asia, Australia, Europe, North America, and South America, where it fruits on the ground in both coniferous and mixed forest.
