Fungi named in 1889

Astraeus hygrometricus, commonly known as the hygroscopic earthstar, the barometer earthstar, or the false earthstar, is a species of fungus in the family Diplocystaceae. Despite a similar overall appearance, A. hygrometricus is not related to the true earthstars of genus Geastrum, although historically, they have been taxonomically confused. The species was first described by Christiaan Hendrik Persoon in 1801 as Geastrum hygrometricus. In 1885, Andrew P. Morgan proposed that differences in microscopic characteristics warranted the creation of a new genus Astraeus distinct from Geastrum;

Agrocybe praecox, commonly known as the spring agrocybe, early agrocybe, or spring fieldcap, is a species of fungus. According to modern analysis, it is one of a cluster of closely similar species, known as the A. praecox complex. It appears early in the year in woods, gardens, and fields in Eurasia, North Africa, and North America. It is of debatable culinary interest.

Cystoderma amianthinum, commonly called the common powdercap, saffron parasol, the saffron powder-cap, or the earthy powder-cap, is a small orange-ochre, or yellowish-brown, gilled mushroom. It grows in damp mossy grassland, in coniferous forest clearings, or on wooded heaths. It is probably the most common of the small genus Cystoderma. It is not recommended for consumption due to its resemblance to poisonous species.

Conocybe is a genus of mushrooms with Conocybe tenera as the type species and at least 243 other species. There are at least 50 different species in North America. Most have a long, thin fragile stipe and are delicate, growing in grasslands on dead moss, dead grass, sand dunes, decayed wood, and dung. Conocybe species generally prefer fertile soils in lawns and pastures and are found worldwide. Conocybe species are sometimes called dunce caps or cone heads due to their conical or bell-shaped caps. Former species of Conocybe that have a well-developed partial veil and/or lack lecythiform

Malassezia furfur (formerly known as Pityrosporum ovale) is a species of yeast (a type of fungus) that is naturally found on the skin surfaces of humans and some other mammals. It is associated with a variety of dermatological conditions caused by fungal infections, notably seborrhoeic dermatitis and tinea versicolor. As an opportunistic pathogen, it has further been associated with dandruff, malassezia folliculitis, pityriasis versicolor (alba), and malassezia intertrigo, as well as catheter-related fungemia and pneumonia in patients receiving hematopoietic transplants and patients receiving

Lepiota brunneoincarnata, the deadly dapperling, is a gilled mushroom of the genus Lepiota in the order Agaricales. Widely distributed in Europe and temperate regions of Asia as far east as China, it grows in grassy areas such as fields, parks and gardens, and is often mistaken for edible mushrooms. The mushroom has a brown scaled cap up to 4 cm wide with a pinkish brown stem and white gills. It is highly toxic, with several deaths having been recorded as it resembles the edible grey knight (Tricholoma terreum) and fairy ring champignon (Marasmius oreades).

Agrocybe is a genus of mushrooms in the family Strophariaceae (previously placed in the Bolbitiaceae). The genus has a widespread distribution, and contains about 100 species.

Discina ancilis, commonly known as pig's ears is a brown to tannish, wrinkled, cup- or ear-shaped fungus, sometimes with short, stout stalk.

Omphalotus is a genus of basidiomycete mushroom, in the family Omphalotaceae, formally circumscribed by Victor Fayod in 1889. Members have the traditional cap and stem structure. They are saprobic, and fruit in clumps on the ground, adjacent to host trees. The best known and type species is the jack-o'-lantern mushroom (Omphalotus olearius). Species of Omphalotus have been mistaken for chanterelles. All Omphalotus species are presumed poisonous, causing gastrointestinal symptoms. Some Omphalotus species have bioluminescent properties.

Malassezia is a genus of fungi (specifically, a yeast belonging to the division Basidiomycota). Some species of Malassezia are found on the skin of animals, including humans. Because malassezia requires fat to grow, it is most common in areas with many sebaceous glands—on the scalp, face, and upper part of the body.

Cystoderma carcharias, is a species of agaric in the fungal family Agaricaceae. It has a widespread distribution, and has been collected in coniferous forests and grasslands in Asia, Europe, North America, and the subantarctic islands. In the field, fruit bodies are characterized by a pink cap up to 6 cm (2.4 in) broad, a well-developed ring on the stem, and an unpleasant odour.

Cystoderma is a genus of fungi in the family Agaricaceae or Cystodermataceae. Its family position is in doubt and the family "Cystodermataceae" and tribe "Cystodermateae" have been proposed to include this group following recent molecular work. Previously Cystoderma comprised a wider range of species but in 2002 Harmaja separated some of them off into the new genus Cystodermella (for instance Cystoderma cinnabarinum, C. elegans and C. granulosum). The separation was made largely on the basis that the spores in the new genus were not at all amyloid. Those remaining in Cystoderma have weakly to

Lactarius porninsis, the larch milkcap, is a member of the large milk-cap genus Lactarius in the order Russulales. It is found in Europe and Asia, where it grows in a mycorrhizal association with larch.

Amanita franchetii, also known as Franchet's amanita, is a species of fungus in the family Amanitaceae.

Agrocybe pediades, commonly known as the common fieldcap, common agrocybe, or hemispheric fieldcap, is a species of fungus. It can be found on grassland. It is potentially edible, but it could be confused with poisonous species, including one of the genus Hebeloma.

Boletopsis leucomelaena is a species of hydnoid fungus in the family Bankeraceae. The fungus is listed as a priority species in the United Kingdom Biodiversity Action Plan. B. leucomelaena is found in the Pacific Northwest region of North America, in Japan, and throughout Europe, although it is less common than the lookalike B. grisea.

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 (3⁄4 in) across. They have a short, tapered stalk. The fungus is distributed throughout many temperate regions of the Northern Hemisphere. It is found in Europe, Turkey, and North America. Fruitbodies

Covered smut of barley is caused by the fungus Ustilago hordei. The disease is found worldwide and it is more extensively distributed than either loose smut or false loose smut.

Crinipellis is a genus of fungus in the family Marasmiaceae. The genus has a widespread distribution and contains about 65 species.

Boletopsis is a genus of mycorrhizal fungi in the family Bankeraceae. The genus was circumscribed by Swiss mycologist Victor Fayod in 1889, with Boletopsis leucomelaena as the type species.

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.

Physisporinus vitreus is a species of crust fungus in the family Meripilaceae, and the type species of the genus Physisporinus. It was originally described by Christian Hendrik Persoon by 1796. Petter Adolf Karsten transferred it to the genus Physisporinus in 1889.

Geopyxis is a genus of fungi in the family Pyronemataceae. The genus has a widespread distribution. Molecular phylogenetic studies published in 2007 suggest that the genus is not monophyletic.

Ceratiomyxa is a genus of plasmodial slime mould within the Eumycetozoa, first described by Pier Antonio Micheli. They are widely distributed and commonly found on decaying wood. The plasmodium often appears as white frost-like growth or thin watery layers on wood. Pillar or wall-like sporangia bud from the plasmodium and develop spores that undergo multiple divisions before they release flagellated zoospores. The zoospores will then pair off, undergo plasmogamy, and form zygotes that will later form new plasmodia. The genus currently contains four species. The most notable member is

Astraeus is a genus of fungi in the family Diplocystaceae. The genus, which has a cosmopolitan distribution, contains nine species of earthstar mushroom. They are distinguished by the outer layer of flesh (exoperidium) that at maturity splits open in a star-shape manner to reveal a round spore sac. Additionally, they have a strongly hygroscopic character—the rays will open when moist, but when hot and dry will close to protect the spore sac. Species of Astraeus grow on the ground in ectomycorrhizal associations with trees and shrubs. Despite their similar appearance to the Geastrum

Asterostroma is a genus of fungi in the Peniophoraceae family. The genus contains 26 species, which collectively have a widespread distribution.

Physisporinus is a genus of fungi in the family Meripilaceae. The genus was circumscribed by Finish mycologist Petter Karsten in 1889.

Onnia tomentosa is a species of fungus in the family Hymenochaetaceae commonly known as the woolly velvet polypore. It is a plant pathogen, causing root rot especially in spruce trees.

Onnia is a genus of fungi in the family Hymenochaetaceae. The widely distributed genus contains five species. The genus name of Onnia is in honour of Onni Alexander Karsten (1868-1958), who was a Finnish gardener, who worked at the Mustiala Agriculture Institute in Tampere. Onni Alexander Karsten was also the son of Petter Adolf Karsten and the genus was circumscribed by Petter Adolf Karsten in Bidrag Kännedom Finlands Natur Folk vol.48 on pages 326 - 376 in 1889.
