Sarcosoma globosum, or witches cauldron, [1] is a species of fungus in the family Sarcosomataceae. [3] It was first described in 1793 by Casimir Christoph Schmidel. Johann Xaver Robert Caspary transferred it to the genus Sarcosoma in 1891.
Also known as the charred-pancake cup, [1] it is a near-threatened fungus native to Northern Europe. It is rarely found in some parts of northeastern North America, particularly in the Great Lakes region. [4] To biologists' surprise, in 2021 it was found in Northern British Columbia. [5]
The witches cauldron is an ascomycete or sac fungus, meaning that its microscopic structure utilizes the ascus, a spore-bearing cell, for sexual reproduction. It is a detritivore, and survives on decomposing plant matter, most commonly leaf litter. It is found in spruce forests and does not currently have any human uses. [4]
Sarcosoma globosum is most commonly studied in Northern Europe, particularly Sweden. However, its population has been in decline for the past 50 years. The organism's preference of well-drained, nutrient-rich soil near rivers and streams within light spruce forests has caused the fungus to go extinct in several central European countries.
It is native to Canada, Czech Republic, Estonia, Finland, Latvia, Norway, Poland, Russia, Sweden, Ukraine, and the United States. It has been classified as extirpated in Germany, Lithuania, and Slovakia.
The witches cauldron is found along streams and brooks in Northern Europe, where it has been studied and observed most thoroughly in Estonia, Finland, and Sweden, while in Norway it has become nearly extinct. The fruit bodies of the Sarcosoma globosum are described as big, round, and barrel-like, 5-10 centimeters in diameter. Dark brown and even blackish in color, the witches cauldron can be glossy and velvety with a gelatinous substance inside. Its fruit bodies flatten and wrinkle with time.
The striking appearance of the fungus has made it easy to spot for tourists, who later report their findings to museums and researchers. [5]
Some of the habitats of this fungus have been destroyed due to human activity associated with urban sprawl, such as the building of roads and houses, or forestry. However, some anthropogenic habitat degradation has actually allowed the species to flourish. Dense forest is not suitable for the Sarcosoma globosum and, therefore, the introduction of grazing cattle into the agroforest actually allowed the fungus to flourish in 1950s. The species seems to grow well in selective logging zones, but it is unable to persist in forests that have ever been clear-cut. [6]
This ascomycete fungus is nationally red-listed or classified as rare in 12 countries and regions in Europe. [6] The Swedish EPA developed a Species Action plan for Sarcosoma globosum from 2010 to 2014.
Armillaria is a genus of fungi that includes the A. mellea species known as honey fungi that live on trees and woody shrubs. It includes about 10 species formerly categorized summarily as A. mellea. Armillarias are long-lived and form the largest living fungi in the world. The largest known organism covers more than 3.4 square miles (8.8 km2) in Oregon's Malheur National Forest and is estimated to be 2,500 years old. Some species of Armillaria display bioluminescence, resulting in foxfire.
Polypores are a group of fungi that form large fruiting bodies with pores or tubes on the underside. They are a morphological group of basidiomycetes-like gilled mushrooms and hydnoid fungi, and not all polypores are closely related to each other. Polypores are also called bracket fungi or shelf fungi, and they characteristically produce woody, shelf- or bracket-shaped or occasionally circular fruiting bodies that are called conks.
Lactarius deterrimus, also known as false saffron milkcap or orange milkcap, is a species of fungus in the family Russulaceae. The fungus produces medium-sized fruit bodies (mushrooms) with orangish caps up to 12 centimetres wide that develop green spots in old age or if injured. Its orange-coloured latex stains maroon within 30 minutes. Lactarius deterrimus is a mycorrhizal fungus that associates with Norway spruce and bearberry. The species is distributed in Europe, but has also found in parts of Asia. A visually similar species in the United States and Mexico is not closely related to the European species. Fruit bodies appear between late June and November, usually in spruce forests. Although the fungus is edible—like all Lactarius mushrooms from the section Deliciosi—its taste is often bitter, and it is not highly valued. The fruit bodies are used as source of food for the larvae of several insect species. Lactarius deterrimus can be distinguished from similar Lactarius species by difference in the mycorrhizal host or latex colour.
The Siberian flying squirrel is an Old World flying squirrel ranging from the Baltic Sea in the west, throughout Northern Asia to the coast of the Pacific Ocean in the east. It is the only species of flying squirrel in Europe and is considered vulnerable in the European Union where it occurs only in Estonia and Finland. In Latvia, it was last sighted in 2001 and has been considered to be locally extinct since 2013.
Fomitopsis pinicola, is a stem decay fungus common on softwood and hardwood trees. Its conk is known as the red-belted conk. The species is common throughout temperate Europe and Asia. It is a decay fungus that serves as a small-scale disturbance agent in coastal rainforest ecosystems. It influences stand structure and succession in temperate rainforests. It performs essential nutrient cycling functions in forests. As well as a key producer of brown rot residues that are stable soil components in coniferous forest ecosystems. It has been reported that mushrooms have significant antioxidant activity.
The Pertusariales are an order of fungi in the class Lecanoromycetes, comprising 8 families, 31 genera, and over 600 species, many of which form lichens. This diverse group is characterized by complex taxonomic history and ongoing phylogenetic revisions. Originally circumscribed by lichenologists David L. Hawksworth and Ove Eriksson in 1986, Pertusariales has undergone significant reclassification due to molecular phylogenetics studies. The order includes well-known genera such as Pertusaria and Ochrolechia, as well as families like Megasporaceae and Icmadophilaceae.
Geopyxis carbonaria is a species of fungus in the genus Geopyxis, family Pyronemataceae. First described to science in 1805, and given its current name in 1889, the species is commonly known as the charcoal loving elf-cup, dwarf acorn cup, stalked bonfire cup, or pixie cup. The small, goblet-shaped fruitbodies of the fungus are reddish-brown with a whitish fringe and measure up to 2 centimetres across. They have a short, tapered stalk.
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.
Urnula is a genus of cup fungi in the family Sarcosomataceae, circumscribed by Elias Magnus Fries in 1849. The genus contains several species found in Asia, Europe, Greenland, and North America. Sarcosomataceae fungi produce dark-colored, shallow to deep funnel-shaped fruitbodies with or without a stipe, growing in spring. The type species of the genus is Urnula craterium, commonly known as the devil's urn or the gray urn. Urnula species can grow as saprobes or parasites having an anamorphic state. The anamorphic form of U. craterium causes Strumella canker, on oak trees.
Caloscypha is a fungal genus in the family Caloscyphaceae. A monotypic genus, it contains the single species Caloscypha fulgens, commonly known as the snowbank orange peel fungus, spring orange peel fungus, the golden cup, or the dazzling cup. It is a cup fungus, typically up to 4 centimetres in diameter, with a bright to pale orange interior and orange; specimens that are old or bruised often have an olive-green discoloration, especially around the edges.
Armillaria ectypa is a species of mushroom in the family Physalacriaceae. Commonly known as the marsh honey fungus, it prefers growing in sphagnum bogs with mosses. It is classified as endangered in Great Britain, and is protected under the Wildlife and Countryside Act 1981; it is also on the provisional European red data list. A. ectypa has been observed to have both bioluminescent mycelium and fruitbodies.
Sarcosoma is a genus of fungi in the family Sarcosomataceae. The name Sarcosoma is derived from ancient Greek and means “Fleshy body” σάρξ σῶμα. The genus is widespread in north temperate areas.
Sarcosphaera is a fungal genus within the Pezizaceae family. It is a monotypic genus, containing the single species Sarcosphaera coronaria, commonly known as the pink crown, the violet crown-cup, or the violet star cup. Although several taxa have been described as Sarcosphaera species since the introduction of the genus in 1869, most lack modern descriptions, have been transferred to the related genus Peziza, or are considered synonymous with S. coronaria.
Galiella rufa, commonly known as the rubber cup, the rufous rubber cup, or the hairy rubber cup, is a species of fungus in the family Sarcosomataceae. It produces cup-shaped fruit bodies with the texture of tough, gelatinous rubber, with a rough, blackish-brown, felt-like outer surface and a smooth reddish-brown inner surface.
A snowbank fungus is any one of a number of diverse species of fungi that occur adjacent to or within melting snow. They are most commonly found in the mountains of western North America where a deep snowpack accumulates during the winter and slowly melts through the spring and summer, often shaded by coniferous forest. They may be saprotrophic, mycorrhizal, or in the case of Caloscypha fulgens, pathogenic.
Protostropharia alcis is a species of coprophilous agaric fungus in the family Strophariaceae. The fungus produces fruit bodies on moose, elk, and deer dung. The species has been recorded in Europe, Canada and Brazil.
Mycena purpureofusca, commonly known as the purple edge bonnet, is a species of agaric fungus in the family Mycenaceae. First described by Charles Horton Peck in 1885, the species is found in Europe and North America, where it grows on the decaying wood and debris of conifers, including cones. Fruit bodies have conical to bell-shaped purple caps up to 2.5 cm (1 in) set atop slender stipes up to 10 cm (4 in) long. The mushroom is named for the characteristic dark greyish-purple color of its gill edges. In the field, M. purpureofusca mushrooms can usually be distinguished from similar species by characteristics such as the dark purple gill edges, the deep purple cap center, and its cartilagineous consistency. The fungus contains a laccase enzyme that has been investigated scientifically for its potential to detoxify recalcitrant industrial dyes used in textile dyeing and printing processes.
Hydnellum mirabile is an inedible species of tooth fungus in the family Bankeraceae. It is found in Europe and North America, where it grows in old-growth, coniferous forests on base-rich or chalky soils. It forms mycorrhiza with Norway Spruce and occasionally Scots Pine.
Buellia asterella, commonly referred to as the starry breck lichen, is a rare, black and white lichen in the family Caliciaceae. Once found all across the central European grasslands, it was described as new to science in 1974. Today, it is classified by the IUCN Red List as Critically Endangered and only found in select regions in Norway and Germany.
Amylocystis lapponica is a species of bracket fungus in the family Fomitopsidaceae, and the type species of genus Amylocystis. It produces medium-sized, annual fruit bodies that are soft, and have a strong, distinct smell. The fungus is a saprophyte that feeds on coniferous wood of logs lying on the ground, and causes brown rot. It is a rather rare species that only occurs in old-growth forest.
