Ossicaulis semiocculta (Cleland) J.A. Cooper 2023 | |
Ossicaulis semiocculta is a small wood-rotting mushroom species. It was originally described by John Burton Cleland in 1927 as Cliyocybe semiocculta. [1] It was transferred to the genus Ossicaulis by Jerry A. Cooper in 2023. [2]
Pileus 1.2 to 6.2 cm diameter, at first slightly convex with down turned edge, then sometimes expanded and upturned, often depressed over the attachment of the stem, wavy, irregular and more or less lobed at the margin, when found growing usually whitish to dingy whitish or pale buffy white (Cartridge Buff, XXX.) or creamy white and opaque, smooth, a little translucent when very moist, when gathered becoming Ochraceous Buff (XV.) round the edge and even browner in the centre, herbarium specimens drying a dingy biscuit colour. Gills adnate to sometimes slightly decurrent, close, narrow, whitish, then creamy-white. Stem short, 1.2 to 2.5 cm, central to excentric or occasionally almost lateral from the position in which it may have grown, similarly often bent, slender or rather stout, equal or slightly attenuated downwards, pruinose, tough, hollow above, the colour of the pileus. Flesh thin, equally attenuated outwards. Spores nearly subspherical, 3.5 to 4 x 2.5 to 2.8 μm, 4 μm. Sometimes caespitose (growing in dense tufts or clusters). Attached by fluffy-white mycelium to the undersides of thick sheets of fallen or stripped bark and fallen wood on the ground beneath eucalypts, or around the base of stumps, the pilei often emerging with difficulty or only found after removing overlying litter. [3] Cleland used Ridgeway colour standard and nomenclature. [4]
South-eastern Australia (NSW, Victoria, South Australia) south Western Australia and Tasmania. [3] [5] New Zealand. [6]
Eucalyptus forest in Australia. [3] In New Zealand recorded on tree ferns (Cyathea medullaris), gymnosperms ( Dacrycarpus dacrydioides ). monocotyledons ( Cordyline australis , Cordyline indivisa , Phormium , Rhopalostylis sapida , and Ripogonum scandens ), and dicotyledons (Nothofagacea). [6]
Growing on decomposing wood. [3] In New Zealand recorded on dead and decaying tree fern fronds, and fibrous monocotyledon leaf and stem material. [6]
From Latin, semi, half; occult us, hidden. The specific name alludes to the frequency with which the mushrooms are often more or less hidden under bark and debris. [3]
For current taxonomic relationship of the genus see Ossicaulis. As Cliyocybe semiocculta the pale colouration of the pileus, the adnate to slightly decurrent gills, the presence of clamp connections and the absence of cystidia indicate it belongs in Subgenus Clitocybe, Section Disciformes. [7]
Molecular genetics analysis suggests that Ossicaulis is most closely related to the genera Asterophora , Hypsizygus , Lyophyllum , and Tricholomella . [8]
Psilocybe caerulipes, commonly known as blue-foot, is a rare psilocybin mushroom of the family Hymenogastraceae, having psilocybin and psilocin as main active compounds. An older synonym is Agaricus caerulipes.
Clitocybe nebularis or Lepista nebularis, commonly known as the clouded agaric, cloudy clitocybe, or cloud funnel, is an abundant gilled fungus which appears both in conifer-dominated forests and broad-leaved woodland in Europe and North America. Appearing in Britain from mid to late autumn, it is edible, but may cause gastrointestinal issues.
Gymnopilus aeruginosus, also known as the magic blue gym, is a mushroom-forming fungus that grows in clusters on dead wood and wood chip mulch. It is widely distributed and common in the Pacific Northwest. It has a rusty orange spore print and a bitter taste and contains the psychedelic chemical psilocybin. It was given its current name by mycologist Rolf Singer in 1951.
Psilocybe subaeruginosa is a species of agaric fungus in the family Hymenogastraceae described in 1927 and known from Australia and New Zealand. As a blueing member of the genus Psilocybe it contains the psychoactive compounds psilocin and psilocybin.
Russula delica is a mushroom that goes by the common name of milk-white brittlegill, and is a member of the genus Russula, all of which are collectively known as brittlegills. It is mostly white, with ochraceous or brownish cap markings, and a short robust stem. It is edible, but poor in taste, and grows in coniferous, broadleaved, or mixed woods. It can be confused with other white Russula species and certain white Lactarius species.
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.
Cortinarius rotundisporus, also known as the elegant blue webcap, is a basidiomycete mushroom of the genus Cortinarius found in southern Australia, where it is found in eucalypt forests and rainforests. The cap of the fruit body is a steely blue colour, with a yellowish boss, and paler similarly coloured stipe.
Macrolepiota clelandii, commonly known as the slender parasol or graceful parasol, is a species of mushroom-forming fungus in the family Agaricaceae. The species is found in Australia and New Zealand, where it fruits singly or in small groups on the ground in eucalypt woodlands, parks, and roadsides. It is a tall mushroom up to roughly 20 cm (8 in), with a broad cap covered with distinctive rings of dark brown scales. The whitish gills on the cap underside are closely spaced and free from attachment to the slender stipe, which has a loose ring on its upper half, and a bulbous base. The edibility of the mushroom is not known with certainty, but closely related parasol mushrooms are edible and some are very sought after.
Russula albidula is a species of mushroom in the genus Russula. The species, known in the vernacular as the boring white russula or the whitish brittlegill, is nondescript, with a small or medium dirty white fruit body, and a highly acrid taste. It is found in eastern North America.
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.
Mycena maculata, commonly known as the reddish-spotted Mycena, is a species of fungus in the family Mycenaceae. The fruit bodies, or mushrooms, have conic to bell-shaped to convex caps that are initially dark brown but fade to brownish-gray when young, reaching diameters of up to 4 cm. They are typically wrinkled or somewhat grooved, and have reddish-brown spots in age, or after being cut or bruised. The whitish to pale gray gills also become spotted reddish-brown as they mature. The stem, up to 8 cm (3 in) long and covered with whitish hairs at its base, can also develop reddish stains. The mycelium of M. maculata has bioluminescent properties. The saprobic fungus is found in Europe and North America, where it grows in groups or clusters on the rotting wood of both hardwoods and conifers. The edibility of the fungus is unknown. Although the species is known for, and named after its propensity to stain reddish, occasionally these stains do not appear, making it virtually indistinguishable from M. galericulata.
Ossicaulis is a ditypic genus of mushrooms in the family Lyophyllaceae.
Lactarius torminosulus is a member of the large milk-cap genus Lactarius, in the order Russulales. A European species, it was officially described in 1996 from collections made in Norway. Fruit bodies (mushrooms) are small to medium-sized, yellowish orange in colour. Young specimens have a hairy cap margin; these hairs slough off in maturity—a field characteristic that can be used to help distinguish this species from the similar Lactarius torminosus. The fungus grows in a mycorrhizal association with dwarf birch species.
Protostropharia semiglobata, commonly known as the dung roundhead, the halfglobe mushroom, or the hemispherical stropharia, is an agaric fungus of the family Strophariaceae. A common and widespread species with a cosmopolitan distribution, the fungus produces mushrooms on the dung of various wild and domesticated herbivores. The mushrooms have hemispherical straw yellow to buff-tan caps measuring 1–4 cm (0.4–1.6 in), greyish gills that become dark brown in age, and a slender, smooth stem 3–12 cm (1.2–4.7 in) long with a fragile ring.
Clitocybe albirhiza, commonly known as the snowmelt clitocybe, is a species of agaric fungus in the family Tricholomataceae. It is found in high-elevation locations in the western United States.
Lactifluus clarkeae, formerly known as Lactarius clarkeae, is a species of mushroom-forming fungus in the family Russulaceae. It is found in Australia and New Zealand in mycorrhizal association with species of Nothofagus and the family Myrtaceae.
Austrocortinarius australiensis, commonly known as the skirt webcap, is a species of mushroom in the family Cortinariaceae which is native to Australia and New Zealand. The white mushrooms appear in autumn and can grow very large, with their caps reaching 30 cm (12 in) in diameter.
Amanita flavorubens, also known as the yellow American blusher or the yellow American blushing amanita, is a species of fungus in the family Amanitaceae.
Amanita longipes is a small mushroom species of the Amanita genus. It feeds on decaying leaves of some woods and can be found around the Appalachian Mountains. It is a food source for various insects.
Pleurotus parsonsiae, also known as velvet oyster mushroom, is a species of edible fungus in the genus Pleurotus, endemic to New Zealand.
