A cuticle, or cuticula, is any of a variety of tough but flexible, non-mineral outer coverings of an organism, or parts of an organism, that provide protection. Various types of "cuticle" are non-homologous, differing in their origin, structure, function, and chemical composition.
Crepidotus versutus, commonly known as the evasive agaric, is a species of fungi in the family Crepidotaceae. It is saprobic on wood, like other Crepidotus species, but it can also decompose herbaceous forest litter. The species is characterized by large, punctate, ellipsoid spores, and the white, hairy pileus.
Gymnopilus cyanopalmicola is a species of mushroom in the Cortinariaceae family. Found in tropical Mexico, it was described as new to science by Mexican mycologist Laura Guzmán-Dávalos in 2006. The flesh of this mushroom bruises blue where bruised.
Entoloma austroprunicolor is a species of agaric fungus in the family Entolomataceae. Described as new to science in 2007, it is found in Tasmania, where it fruits on the ground of wet sclerophyll forests in late spring to early winter. The fruit bodies (mushrooms) have reddish-purple caps measuring up to 5 cm (2.0 in) in diameter supported by whitish stipes measuring 3–7.5 cm (1.2–3.0 in) long by 0.2–0.6 cm (0.1–0.2 in) thick. On the cap underside, the crowded gills are initially white before turning pink as the spores mature.
Hygrophorus agathosmus, commonly known as the gray almond waxy cap or the almond woodwax, is a species of fungus in the Hygrophoraceae family. It was first described by Elias Magnus Fries in 1815; Fries gave it its current name in 1838. A widespread species, it is distributed in the United States, Europe, Africa, and India, and can be found growing under spruce and pine in mixed forests. The fruit bodies are characterized by a light grayish cap that measures up to 8 cm (3.1 in) in diameter, waxy gills, a dry stem, and the distinct odor of bitter almonds. An edible but bland-tasting mushroom, extracts of the fruit bodies have been shown in laboratory tests to have antimicrobial activity against various bacteria that are pathogenic to humans.
Lactarius argillaceifolius is a species of fungus in the Russulaceae family. The mushrooms produced by the fungus have convex to flattened drab lilac-colored caps that are up to 18 cm (7.1 in) wide. The cream-colored gills are closely spaced together and extend slightly down the length of the stem, which is up to 9 cm (3.5 in) long by 3.5 cm (1.4 in) thick. The mushroom produces an off-white latex when injured that stains the mushroom tissue brownish.
Mycena clariviolacea is a mushroom in the Mycenaceae family. First reported as a new species in 2007, it is known only from Kanagawa, Japan, where it fruits on dead fallen twigs in forests dominated by oak and chinquapin trees. Distinctive features of this species are found in its medium-sized, dark violet fruit bodies, with caps up to 25 mm (0.98 in) in diameter and slender stems that are about 30 to 40 mm long. Microscopic characteristics include the amyloid spores, the club-shaped cheilocystidia that are covered with one or more, knob-like, apical protuberances, the absence of pleurocystidia, and the cylindrical, diverticulate caulocystidia.
Mycena fonticola is a species of fungus in the Mycenaceae family. First reported in 2007, it is known only from central Honshu, in Japan, where it grows on dead leaves and twigs in low-elevation forests dominated by oak trees. The fruit body of the fungus has a smooth, violet-brown cap up to 2.5 cm (1.0 in) in diameter, and a slender stem up to 10 cm (3.9 in) long. Distinguishing microscopic characteristics of the mushroom include the relatively large, distinctly amyloid spores, the smooth, spindle-shaped cheilocystidia, the absence of pleurocystidia, the diverticulate hyphae of the cap cuticle, and the absence of clamp connections.
Mycena intersecta is a species of mushroom in the Mycenaceae family. First reported as a new species in 2007, it is known only from central Honshu, in Japan, where it is found growing solitarily or scattered, on dead leaves in lowland forests dominated by oak. The mushrooms have olive-brown caps up to 12 mm (0.47 in) in diameter atop slender stems that are 50 to 80 mm long by 0.7 to 1.2 mm thick. On the underside of the cap are the distantly spaced, whitish gills that have cross-veins running between them. Microscopic characteristics of the mushroom include the smooth, irregularly cylindrical cheilocystidia, the absence of pleurocystidia, the diverticulate elements of the cap cuticle, the broadly club-shaped to irregularly shaped caulocystidia, the weakly dextrinoid flesh, and the absence of clamp connections. The edibility of the mushroom is unknown.
Mycena lanuginosa is a species of mushroom in the Mycenaceae family. First collected in 2000 and reported as a new species in 2007, it is known only from lowland oak-dominated forests in central Honshu in Japan. The small mushroom is characterized by its grooved, grayish-brown to violet-brown cap up to 11 mm (0.43 in) in diameter, and the slender grayish-brown to reddish-brown stem covered with minute, fine, soft hairs. The mushroom produces amyloid spores. Microscopic distinguishing features include the smooth, spindle-shaped cheilocystidia and pleurocystidia and the diverticulate elements in the outer layer of the cap and the stem.
Entoloma haastii is a mushroom in the Entolomataceae family. Described as new to science in 1964, it is known only from New Zealand, where it grows on the ground in leaf litter, usually near Nothofagus species.
Spongiforma is a genus of sponge-like fungi in the Boletaceae family. Newly described in 2009, the genus contains two species: S. thailandica and S. squarepantsii. The type species S. thailandica is known only from Khao Yai National Park in central Thailand, where it grows in soil in old-growth forests dominated by dipterocarp trees. The rubbery fruit bodies, which has a strong odour of coal-tar similar to Tricholoma sulphureum, consists of numerous internal cavities lined with spore-producing tissue. S. squarepantsii, described as new to science in 2011, is found in Malaysia. It produces sponge-like, rubbery orange fruit bodies with a fruity or musky odour. These fruit bodies will—like a sponge—resume their original shape if water is squeezed out. The origin of the specific name derives from its perceived resemblance to the cartoon character SpongeBob SquarePants. Apart from differences in distribution, S. squarepantsii differs from S. thailandica in its colour, odour, and spore structure.
Marasmius funalis is a species of Marasmiaceae fungus known only from Japan. The species produces small mushrooms with reddish-brown caps up to 6 millimetres (0.24 in) in diameter and dark-brown, threadlike stems of up to 50 millimetres (2.0 in) in length. The species has a number of distinctive microscopic features, including very long cystidia on the stem, visible as bristles. Described in 2002 by Haruki Takahashi, the species grows on dead wood. The closest relative of M. funalis is M. liquidambari, known from Mexico and Papua New Guinea, and it is also similar in appearance to M. hudonii and Setulipes funaliformis, the latter of which was named after M. funalis.
Lactarius rupestris is a species of mushroom in the Russulaceae family. Described as a new species in 2010, it is known only from the semi-arid region in the National Park of Catimbau of Brazil. The mushroom is characterized by a stout fruit body with a smooth and sticky orange cap up to 7 cm (2.8 in) in diameter. The gills on the underside of the cap are closely spaced and frequently anastomosed. The stem is 35–45 mm (1.4–1.8 in) long by 18–21 mm (0.71–0.83 in) thick. The mushrooms exude a sparse cream-colored latex when cut or injured.
Volvopluteus asiaticus is a species of mushroom in the Pluteaceae family. The cap of this mushroom is about 70–90 mm (2.8–3.5 in) in diameter, greyish brown to brown. The gills start out white but they soon turn pink. The stipe is white and has a volva at the base. Microscopical features and DNA sequence data are of great importance for separating this taxon from related species. V. asiaticus is a saprotrophic fungus that was originally described as growing on the ground, in the humus layer. It is only known from Hokkaido (Japan).
Lepiota maculans is a rare species of agaric fungus in the family Agaricaceae. It was originally collected in Missouri, and then 105 years later in eastern Tennessee. It is the only member of Lepiota known to have a pink spore print instead of the usual white or cream color. The fruit bodies have caps up to 4 cm (1.6 in) in diameter, with brownish, sparsely scaled centers. The gills are closely spaced, not attached to the stipe, and discolor reddish at the edges.
Boletus subluridellus is a species of bolete fungus in the family Boletaceae. Described as new to science in 1971 by American mycologists, the bolete is found in the eastern United States and Canada. It grows on the ground in coniferous and mixed forests in a mycorrhizal association with deciduous trees, especially oak. The fruit bodies (mushrooms) have orangish-red, broadly convex caps that are up to 10 cm (3.9 in) in diameter, with small, dark reddish pores on the underside. The pale yellow stipe measures 4–9 cm (1.6–3.5 in) long by 1.5–2.3 cm (0.6–0.9 in) thick. All parts of the fruit body will quickly stain blue when injured or touched.
Crocinoboletus is a fungal genus in the family Boletaceae. Circumscribed in 2014, it contains two species: Crocinoboletus laetissimus, and the type, C. rufoaureus. This latter bolete was originally described by George Edward Massee in 1909 from collections made in Singapore. The genus is readily characterized by bright orange fruitbodies that readily stain blue-olive when injured, and smooth spores. The cap cuticle is made of a trichoderm in the middle part of the cap, and a cutis at the cap margin. The intense orange color of the fruitbodies is caused by boletocrocin pigments.
Hygrophoropsis rufa is a species of fungus in the family Hygrophoropsidaceae. It is found in Europe, where it grows on woodchips or near conifer stumps.
