Rigidoporus ulmarius is a fungal plant pathogen found mainly on broad-leaved trees. Elm is considered particularly susceptible. [1]

The fruiting bodies are white, knobbly and relatively hard, requiring a fair amount of force to break. Older bodies may be covered with green algae, or partially covered with vegetation and leaves making them difficult to spot. They often encapsulate grass, twigs and other debris.[ citation needed ]

Tubes are 1–5 mm long in each layer, pinkish to orange when young, browning with age, each layer separated by a thin contrasting band of white flesh. Pores 5–8 per millimeter, red-orange fading to clay-pink or buff with age. Spores pale yellow, globose, 6–7.5  µm in diameter. Hyphal structure monomitic; generative hyphae lacking clamps. Habitat at the base of trunks of deciduous trees, usually elm. Season all year, perennial. Common. Not edible. Found in Europe.[ citation needed ]

A fruit body of R. ulmarius discovered in Kew Gardens of London in 2003 was, for a time, the largest known fungal fruit body ever discovered, measuring 150 by 133 centimetres (59 by 52 in) in diameter, and had a circumference of 425 centimetres (167 in). However, in 2011, a specimen of Phellinus ellipsoideus (formerly Fomitiporia ellipsoidea) significantly larger was discovered in China. [2]

<i>Maclura pomifera</i> Species of plant

Maclura pomifera, commonly known as the Osage orange, is a small deciduous tree or large shrub, native to the south-central United States. It typically grows about 8 to 15 metres (30–50 ft) tall. The distinctive fruit, a multiple fruit, is roughly spherical, bumpy, 8 to 15 centimetres (3–6 in) in diameter, and turns bright yellow-green in the fall. The fruits secrete a sticky white latex when cut or damaged. Despite the name "Osage orange", it is not related to the orange. It is a member of the mulberry family, Moraceae. Due to its latex secretions and woody pulp, the fruit is typically not eaten by humans and rarely by foraging animals. Ecologists Daniel H. Janzen and Paul S. Martin proposed in 1982 that the fruit of this species might be an example of what has come to be called an evolutionary anachronism—that is, a fruit coevolved with a large animal seed dispersal partner that is now extinct. This hypothesis is controversial.

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

Phallaceae is a family of fungi, commonly known as stinkhorns, within the order Phallales. Stinkhorns have a worldwide distribution, but are especially prevalent in tropical regions. They are known for their foul-smelling, sticky spore masses, or gleba, borne on the end of a stalk called the receptaculum. The characteristic fruiting-body structure, a single, unbranched receptaculum with an externally attached gleba on the upper part, distinguishes the Phallaceae from other families in the Phallales. The spore mass typically smells of carrion or dung, and attracts flies, beetles and other insects to help disperse the spores. Although there is great diversity in body structure shape among the various genera, all species in the Phallaceae begin their development as oval or round structures known as "eggs". The appearance of Phallaceae is often sudden, as gleba can erupt from the underground egg and burst open within an hour. According to a 2008 estimate, the family contains 21 genera and 77 species.

<i>Ulmus glabra</i> Camperdownii Elm cultivar

The Wych Elm cultivar Ulmus glabra 'Camperdownii', commonly known as the Camperdown Elm, was discovered about 1835–1840 as a young contorted elm growing in the forest at Camperdown House, in Dundee, Scotland, by the Earl of Camperdown's head forester, David Taylor. The young tree was lifted and replanted within the gardens of Camperdown House where it remains to this day. The original tree, which grows on its own roots, is less than 3 m tall, with a weeping habit and contorted branch structure. The earl's gardener is said to have produced the first of what are commonly recognised as Camperdown elms by grafting a cutting to the trunk of a wych elm.

<i>Lansium parasiticum</i> Species of tree

Lansium parasiticum, commonly known as langsat, is a species of tree in the family Meliaceae with commercially cultivated edible fruits. The species is native to Southeast Asia. Despite its name, it is not parasitic; the specific epithet parasiticum derives from the fact that it can grow as an epiphyte in the wild, which was once thought to be an indication of parasitism.

<span class="mw-page-title-main">Agaricomycetes</span> Class of fungi

The Agaricomycetes are a class of fungi in the division Basidiomycota. The taxon is roughly identical to that defined for the Homobasidiomycetes by Hibbett & Thorn, with the inclusion of Auriculariales and Sebacinales. It includes not only mushroom-forming fungi, but also most species placed in the deprecated taxa Gasteromycetes and Homobasidiomycetes. Within the subdivision Agaricomycotina, which already excludes the smut and rust fungi, the Agaricomycetes can be further defined by the exclusion of the classes Tremellomycetes and Dacrymycetes, which are generally considered to be jelly fungi. However, a few former "jelly fungi", such as Auricularia, are classified in the Agaricomycetes. According to a 2008 estimate, Agaricomycetes include 17 orders, 100 families, 1147 genera, and about 21000 species. Modern molecular phylogenetic analyses have been since used to help define several new orders in the Agaricomycetes: Amylocorticiales, Jaapiales, Stereopsidales, and Lepidostromatales.

<span class="mw-page-title-main">Sporocarp (fungus)</span> Fungal structure on which spore-producing structures are borne

The sporocarp of fungi is a multicellular structure on which spore-producing structures, such as basidia or asci, are borne. The fruitbody is part of the sexual phase of a fungal life cycle, while the rest of the life cycle is characterized by vegetative mycelial growth and asexual spore production.

<i>Meripilus giganteus</i> Species of fungus

Meripilus giganteus is a polypore fungus in the family Meripilaceae. It causes a white rot in various types of broadleaved trees, particularly beech (Fagus), but also Abies, Picea, Pinus, Quercus and Ulmus species. This bracket fungus, commonly known as the giant polypore or black-staining polypore, is often found in large clumps at the base of trees, although fruiting bodies are sometimes found some distance away from the trunk, parasitizing the roots. M. giganteus has a circumboreal distribution in the northern Hemisphere, and is widely distributed in Europe. In the field, it is recognizable by the large, multi-capped fruiting body, as well as its pore surface that quickly darkens black when bruised or injured.

<i>Phellinus igniarius</i> Species of fungus

Phellinus igniarius is a fungus of the family Hymenochaetaceae. Like other members of the genus of Phellinus it lives by saprotrophic nutrition, in which the lignin and cellulose of a host tree is degraded and is a cause of white rot. Common names are willow bracket and fire sponge.

<i>Fomitiporia</i> Genus of fungi

Fomitiporia is a genus of fungi in the family Hymenochaetaceae. According to a 2008 estimate, the widely distributed genus contains 11 species, though three new species were identified in 2010 in sub-Saharan Africa using multigene molecular phylogenetic analysis, and two more were named in a 2013 article. In 2011 it was announced that a specimen of the species F. ellipsoidea was discovered with a fruit body that is largest known of any fungus. However, the species has since been moved to Phellinus.

<i>Bridgeoporus</i> Genus of fungi

Bridgeoporus is a fungal genus in the family Polyporaceae. A monotypic genus, it contains the single polypore species Bridgeoporus nobilissimus, first described to science in 1949. Commonly known both as the noble polypore and the fuzzy Sandozi, this fungus produces large fruit bodies that have been found to weigh up to 130 kilograms (290 lb). The upper surface of the fruit body has a fuzzy or fibrous texture that often supports the growth of algae, bryophytes, or vascular plants.

<span class="mw-page-title-main">Largest organisms</span>

This article lists the largest organisms for various types of life and mostly considers extant species, which found on Earth can be determined according to various aspects of an organism's size, such as: mass, volume, area, length, height, or even genome size. Some organisms group together to form a superorganism, but such are not classed as single large organisms. The Great Barrier Reef is the world's largest structure composed of living entities, stretching 2,000 km (1,200 mi), but contains many organisms of many types of species.

<i>Crucibulum</i> Genus of fungi

Crucibulum is a genus in the Nidulariaceae, a family of fungi whose fruiting bodies resemble tiny egg-filled bird's nests. Often called "splash cups", the fruiting bodies are adapted for spore dispersal by using the kinetic energy of falling drops of rain. The "eggs" inside the bird's nests are hard waxy shells containing spores, and tend to stick to whatever nearby herbage they land on, thus increasing the odds of being consumed and dispersed by herbivorous animals. Members of this genus are saprobic, obtaining nutrients from dead organic matter, and are typically found growing on decayed wood and wood debris. The three known Crucibulum species are distinguished from other genera of the Nidulariaceae by their relatively simple funiculus – a cord of hyphae that connects the peridiole to the exterior of the bird's nest.

<i>Chorioactis</i> Genus of fungi that contains the single species Chorioactis geaster

Chorioactis is a genus of fungi that contains the single species Chorioactis geaster. The mushroom is commonly known as the devil's cigar or the Texas star in the United States, while in Japan it is called kirinomitake (キリノミタケ). This extremely rare mushroom is notable for its unusual appearance and disjunct distribution; it is found only in select locales in Texas and Japan. The fruit body, which grows on the stumps or dead roots of cedar elms or dead oaks, somewhat resembles a dark brown or black cigar before it splits open radially into a starlike arrangement of four to seven leathery rays. The interior surface of the fruit body bears the spore-bearing tissue known as the hymenium, and is colored white to brown, depending on its age. The fruit body opening can be accompanied by a distinct hissing sound and the release of a smoky cloud of spores.

<i>Amanita daucipes</i> Species of fungus

Amanita daucipes is a species of fungus in the family Amanitaceae of the mushroom order Agaricales. Found exclusively in North America, the mushroom may be recognized in the field by the medium to large white caps with pale orange tints, and the dense covering of pale orange or reddish-brown powdery conical warts on the cap surface. The mushroom also has a characteristic large bulb at the base of its stem with a blunt short rooting base, whose shape is suggestive of the common names carrot-footed lepidella, carrot-foot amanita, or turnip-foot amanita. The mushroom has a strong odor that has been described variously as "sweet and nauseous", or compared to an old ham bone, or soap. Edibility is unknown for the species, but consumption is generally not recommended due its position in the Amanita subgroup Lepidella, which contains some poisonous members.

<i>Prunus avium</i> Species of flowering plant in the rose family Rosaceae

Prunus avium, commonly called wild cherry, sweet cherry, gean, or bird cherry is a species of cherry, a flowering plant in the rose family, Rosaceae. It is native to Europe, Anatolia, Maghreb, and Western Asia, from the British Isles south to Morocco and Tunisia, north to the Trondheimsfjord region in Norway and east to the Caucasus and northern Iran, with a small isolated population in the western Himalaya. The species is widely cultivated in other regions and has become naturalized in North America and Australia.

<i>Amanita ravenelii</i> Species of fungus

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.

<i>Mycena aurantiomarginata</i> Species of fungus in the family Mycenaceae common in Europe and North America

Mycena aurantiomarginata, commonly known as the golden-edge bonnet, is a species of agaric fungus in the family Mycenaceae. First formally described in 1803, it was given its current name in 1872. Widely distributed, it is common in Europe and North America, and has also been collected in North Africa, Central America, and Japan. The fungus is saprobic, and produces fruit bodies (mushrooms) that grow on the floor of coniferous forests. The mushrooms have a bell-shaped to conical cap up to 2 cm in diameter, set atop a slender stipe up to 6 cm long with yellow to orange hairs at the base. The fungus is named after its characteristic bright orange gill edges. A microscopic characteristic is the club-shaped cystidia that are covered with numerous spiky projections, resembling a mace. The edibility of the mushroom has not been determined. M. aurantiomarginata can be distinguished from similar Mycena species by differences in size, color, and substrate. A 2010 publication reported the discovery and characterization of a novel pigment named mycenaaurin A, isolated from the mushroom. The pigment is responsible for its color, and it has antibiotic activity that may function to prevent certain bacteria from growing on the mushroom.

<i>Phellinus ellipsoideus</i> Species of fungus in the family Hymenochaetaceae found in China

Phellinus ellipsoideus is a species of polypore fungus in the family Hymenochaetaceae, a specimen of which produced the largest fungal fruit body ever recorded. Found in China, the fruit bodies produced by the species are brown, woody basidiocarps that grow on dead wood, where the fungus feeds as a saprotroph. The basidiocarps are perennial, allowing them to grow very large under favourable circumstances. They are resupinate, measuring 30 centimetres (12 in) or more in length, though typically extending less than a centimetre from the surface of the wood. P. ellipsoideus produces distinct ellipsoidal spores, after which it is named, and unusual setae. These two features allow it to be readily differentiated microscopically from other, similar species. Chemical compounds isolated from the species include several steroidal compounds. These may have pharmacological applications, but further research is needed.

<span class="mw-page-title-main">Largest fungal fruit bodies</span> Frugal bodies superlatives

The largest mushrooms and conks are the largest known individual fruit bodies. These are known as sporocarps, or, more specifically, basidiocarps and ascocarps for the Basidiomycota and Ascomycota respectively. These fruit bodies have a wide variety of morphologies, ranging from the typical mushroom shape, to brackets (conks), puffballs, cup fungi, stinkhorns, crusts and corals. Many species of fungi, including yeasts, moulds and the fungal component of lichens, do not form fruit bodies in this sense, but can form visible presences such as cankers. Individual fruit bodies need not be individual biological organisms, and extremely large single organisms can be made up of a great many fruit bodies connected by networks of mycelia can cover a very large area.

<i>Hypsizygus ulmarius</i> Species of mushroom-forming fungus

Hypsizygus ulmarius, also known as the elm oyster mushroom, and less commonly as the elm leech, elm Pleurotus, is an edible fungus. It has often been confused with oyster mushrooms in the Pleurotus genus but can be differentiated easily as the gills are either not decurrent or not deeply decurrent. While not quite as common as true oyster mushrooms, they have a wide range globally in temperate forests. The mushrooms and vegetative hyphae of this species have been studied in recent years for their potential benefits to human health, and mycoremediation.
