Trichia decipiens is a worldwide widespread slime mould species from the order Trichiida.
The plasmodium is white, becoming pink to red at maturity. The small- to large-group-forming fruiting bodies are shiny olive to yellow-olive or brown, and bear mainly stalked, rarely sessile sporangia. These are conical to peak-shaped and are up to 3 mm high and 0.6 to 0.8 (rarely up to 1.3) mm wide. [1]
The shiny, membraneous hypothallus is wide, and pale to brown in colour. The cylindrical stem is wrinkled, dark brown at the base and becoming gradually lighter toward the top, and is filled with up to 1 mm-long, spore-like bodies. The solid or membranous peridium is yellow, often transparent on thin areas, thickened and deeper beneath, surviving as an initially shallow calyculus. [1]
The capillitium from the mass is olive to olive-yellow and is composed of non-overgrown, simple or branched, deeply olive-yellow, 5 to 6 µm thick elaters, which stand in relief as three to five overhanging spiral strands and become pointed towards the end. The spore mass is olive-yellow to olive, in transmitted light appearing pallidly olive-yellow, occasionally paler. The spores are 10 to 13 µm in diameter, and have a largely reticulated surface, the remainder being densely warty or prickly. [1]
The species has a worldwide distribution. [1] T. decipiens slime molds live on the deadwood of conifers and broadleaf trees year-round. The slime mould is associated with, among others, species of the genera Trichia , Arcyria and Cribraria as well as Lycogala epidendrum and Stemonitis typhina . [2]
Trichia decipiens was first described as Arcyria decipiens in 1795 by Christiaan Hendrik Persoon on the basis of a 1778 collection from a forest in Chemnitz. Macbride reclassified the species in 1899 into the genus Trichia . [1]
Slime mold or slime mould is an informal name given to a polyphyletic assemblage of unrelated eukaryotic organisms in the Stramenopiles, Rhizaria, Discoba, Amoebozoa and Holomycota clades. Most are microscopic; those in the Myxogastria form larger plasmodial slime molds visible to the naked eye. The slime mold life cycle includes a free-living single-celled stage and the formation of spores. Spores are often produced in macroscopic multicellular or multinucleate fruiting bodies that may be formed through aggregation or fusion; aggregation is driven by chemical signals called acrasins. Slime molds contribute to the decomposition of dead vegetation; some are parasitic.
Lycogala epidendrum, commonly known as wolf's milk or groening's slime, is a cosmopolitan species of myxogastrid amoeba which is often mistaken for a fungus. The aethalia, or fruiting bodies, occur either scattered or in groups on damp rotten wood, especially on large logs, from June to November. These aethalia are small, pink to brown cushion-like blobs. They may ooze a pink "paste" if the outer wall is broken before maturity. When mature, the colour tends to become more brownish. When not fruiting, single celled individuals move about as very small, red amoeba-like organisms called plasmodia, masses of protoplasm that engulf bacteria, as well as fungal and plant spores, protozoa, and particles of non-living organic matter through phagocytosis.
Myxogastria/Myxogastrea or Myxomycetes (ICN) is a class of slime molds that contains 5 orders, 14 families, 62 genera, and 888 species. They are colloquially known as the plasmodial or acellular slime moulds.
Psilocybe makarorae is a species of psilocybin mushroom in the family Hymenogastraceae. Officially described as new to science in 1995, it is known only from New Zealand, where it grows on rotting wood and twigs of southern beeches. The fruit body (mushroom) has a brownish cap with lighter coloured margins, measuring up to 3.5 cm (1.4 in) wide. The cap shape is either conical, bell-shaped, or flat depending on the age of the mushroom, and it features a prominent umbo. Although the whitish stem does not form a true ring, it retains remnants of the partial veil that covers and protects the gills of young fruit bodies. P. makarorae mushrooms can be distinguished from the similar North American species Psilocybe caerulipes by microscopic characteristics such as the presence of cystidia on the gill faces (pleurocystidia), and cheilocystidia with more elongated necks. Based on the bluing reaction to injury, P. makarorae is presumed to contain the psychedelic compounds psilocybin and psilocin.
Pulveroboletus bembae is a species of fungus in the family Boletaceae that was first described in 2009. It is known only from the rainforest of northern Gabon, a region known for its high level of species diversity. Like all boletes, P. bembae has fleshy fruit bodies that form spores in tubes perpendicular to the ground on the underside of the cap. These yellowish tubes form a surface of pores, each about 1–2 mm in diameter. The brownish caps may reach up to 3.5 cm (1.4 in) wide, and rest atop pale brown stems up to 5.5 cm (2.2 in) long. The stems have a woolly, whitish yellow ring of tissue that is short-lived, and may be absent in older specimens. The spores of P. bembae are spindle- or fuse-shaped, and have rough surfaces—a detail observable when viewed with scanning electron microscopy. The fungus grows in a mycorrhizal relationship with Gilbertiodendron dewevrei, the dominant tree species of the Guineo-Congolian rainforest. Other similar Pulveroboletus species in the area include P. annulus and P. croceus, which may be differentiated from P. bembae by a combination of macro- and microscopic characteristics.
Suillus pungens, commonly known as the pungent slippery jack or the pungent suillus, is a species of fungus in the genus Suillus. The fruit bodies of the fungus have slimy convex caps up to 14 cm (5.5 in) wide. The mushroom is characterized by the very distinct color changes that occur in the cap throughout development. Typically, the young cap is whitish, later becoming grayish-olive to reddish-brown or a mottled combination of these colors. The mushroom has a dotted stem (stipe) up to 7 cm (2.8 in) long, and 2 cm (0.8 in) thick. On the underside on the cap is the spore-bearing tissue consisting of minute vertically arranged tubes that appear as a surface of angular, yellowish pores. The presence of milky droplets on the pore surface of young individuals, especially in humid environments, is a characteristic feature of this species. S. pungens can usually be distinguished from other similar Suillus species by differences in distribution, odor and taste. The mushroom is considered edible, but not highly regarded.
Cortinarius cinnamomeus, also known as the cinnamon webcap, is a basidiomycete mushroom of the genus Cortinarius. The fungus produces brown fruit bodies with caps up to 6 cm (2.4 in) wide and stems up to 12 cm (4.7 in) long. The closely crowded gills underside the cap are initially yellow before turning brown. Cortinarius cinnamomeus is common in damp places in coniferous forests. It is distributed throughout the temperate zone of the Northern Hemisphere.
Cortinarius anomalus, also known as the variable webcap, is a basidiomycete fungus of the genus Cortinarius. It produces a medium-sized mushroom with a grayish-brown cap up to 5 cm (2 in) wide, gray-violet gills and a whitish stem with pale yellow belts below. The mushroom grows solitarily or in scattered groups on the ground in deciduous and coniferous forests. It is found throughout the temperate zone of the northern hemisphere.
Cortinarius vanduzerensis is a species of mushroom in the family Cortinariaceae. Described as new to science in 1972, it is known only from the Pacific Northwest region of North America, where it grows under conifers such as spruce, hemlock, and Douglas-fir. The fruit bodies of the fungus, or mushrooms, have a slimy dark chestnut-brown cap that becomes deeply radially grooved or corrugated in maturity, and reaches diameters of up to 8 cm. The gills on the underside of the cap are initially pinkish-buff before becoming pale brown when the spores mature. The stem is lavender, measuring 10–18 cm (4–7 in) long and 1–2 cm thick. The mushroom produces a rusty-brown spore print, with individual spores measuring 12–14 by 7–8 micrometers. The edibility of the mushroom has not been determined, and it has been described as "much too slippery to be of value".
Boletus rubroflammeus is a species of bolete fungus in the family Boletaceae. First described from Michigan in 1971, it is found in the eastern United States and Mexico, where it grows in a mycorrhizal association with hardwood trees. The fruit bodies (mushrooms) of the fungus have caps that are deep red to purplish red, and dark red pores. The stem has coarse, dark red reticulations and a narrow yellow area at the top. All parts of the mushroom quickly stain blue when injured or cut. Lookalikes include Boletus flammans, a lighter-colored species that grows with conifers. Other similar species can be distinguished by differences in distribution, morphology, staining reaction, and microscopic characteristics. Boletus rubroflammeus mushrooms are poisonous, and can cause gastrointestinal distress if consumed.
Prototrichia metallica is a slime mould species from the order Trichiida and the only species from the genus Prototrichia. It is mainly distributed on mountains.
Physarum aeneum is a slime mould species from the order Physarida. It is one of a few slime moulds mainly common in the tropics and subtropics.
Lindbladia tubulina is a slime mould species from the order Liceida and the only member of its genus.
Boletus abruptibulbus is a species of bolete mushroom in the family Boletaceae. Described as new to science in 2009, it is found only in the Gulf Coast of the Florida Panhandle, where it grows on the ground in coastal sand dunes, one of only three North American boletes known to favor this habitat. The fruit bodies have convex brownish caps up to 8 cm (3.1 in) in diameter, supported by solid yellowish to reddish stems measuring 3–5 cm (1.2–2.0 in) long by 10–15 mm (0.4–0.6 in) thick. The pores on the underside of the cap measure about 1–2 mm in diameter and are initially pale yellow before developing a greenish tinge in age. The mushroom's spores, about 20 micrometers long, are unusually long for a member of the Boletaceae. The stem base is bulbous, a diagnostic feature for which the species is named.
Stemonitis axifera is a species of slime mold. It fruits in clusters on dead wood, and has distinctive tall reddish-brown sporangia, supported on slender stalks.
Amanita basii is a mushroom of the family Amanitaceae.
Hemitrichia is a genus of slime molds, of the family Trichiidae, found within the order Trichiida. It was first described by Josef Rostafinski in 1873 and remains a well-defined genus of the slime molds. Hemitrichia species exhibit either plasmodiocarp or sporangium fruiting bodies, both of which are well-known and recognizable slime molds seen on multiple continents. The genus includes Hemtrichia serpula, known as the pretzel slime mold, an iconic and widespread species that has been used to examine speciation in slime molds.
Trichia crateriformis is a slime mold species in the order Trichiida found in temperate areas throughout the world.
Coenogonium flammeum is a species of corticolous (bark-dwelling), crustose lichen in the family Harpidiaceae. It is found in Argentina.
Amandinea pilbarensis is a little-known species of crustose lichen in the family Physciaceae, First described in 2020, it is found in Australia. It is similar to Amandinea polyxanthonica, but can be distinguished by its smaller ascospores and the presence of calcium oxalate and thiophanic acid in the medulla.
