Fungi named in 1873

Tricholoma portentosum, commonly known as the charbonnier, streaked tricholoma, or sooty head, is a grey-capped mushroom of the large genus Tricholoma. It is found in woodlands in Europe and North America. It is edible but resembles some that are not.

Tricholoma pardinum, commonly known as spotted tricholoma, tiger tricholoma, tigertop, leopard knight, or dirty trich, is a species of gilled mushroom. First officially described by Christiaan Hendrik Persoon in 1801, it has had a confusing taxonomic history that extends over two centuries. In 1762, German naturalist Jacob Christian Schäffer described the species Agaricus tigrinus with an illustration corresponding to what is thought to be T. pardinum, and consequently, the name Tricholoma tigrinum has been used erroneously in some European field guides. The fruit body of Tricholoma pardinum

Dacrymyces chrysospermus is a species of jelly fungus in the family Dacrymycetaceae. In the UK it has the recommended English name of orange jelly spot; in North America it is known as orange jelly or orange witch's butter.

Brefeldia maxima is a species of non-parasitic plasmodial slime mold, and a member of the class Myxomycetes. It is commonly known as the tapioca slime mold because of its peculiar pure white, tapioca pudding-like appearance. A common species with a worldwide distribution, particularly in North America and Europe. It is often found on bark after heavy rain or excessive watering. Their spores are produced on or in aerial sporangia and are spread by wind, however beetles of the family Latridiidae are also reported to disperse the spores. Bonner states that soil invertebrates and rain mainly

Choanephora is a genus of Zygomycota fungi. Choanephora species are known as plant pathogens.

Lycoperdon curtisii is a type of puffball mushroom in the genus Lycoperdon. It was first described scientifically in 1859 by Miles Joseph Berkeley. Vascellum curtisii, published by Hanns Kreisel in 1963, is a synonym. Its fruit bodies (puffballs) have been recorded growing in fairy rings. It is nonpoisonous.

Hypocreopsis is a genus of ascomycete fungi that form ascomata on the stems of trees and shrubs. The ascomata are orange-brown and consist of radiating, perithecial lobes.

Hemitrichia is a genus of slime molds, of the family Trichiaceae, 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. This genus includes species such as H. serpula (known as the pretzel slime mold) and H. decipiens (known as salmon-eggs), both of which are widespread.

Sebacina is a genus of fungi in the family Sebacinaceae. Its species are mycorrhizal, forming a range of associations with trees and other plants. Basidiocarps (fruit bodies) are produced on soil and litter, sometimes partly encrusting stems of living plants. The fruit bodies are cartilaginous to rubbery-gelatinous and variously effused (corticioid) to coral-shaped (clavarioid). The genus has a cosmopolitan distribution.

Leptosphaeria acuta (also known as nettle rash) is a plant pathogen found on the dead stems of common nettle (Urtica dioica).

Lepraria lobificans is a species of leprose lichen in the family Stereocaulaceae. The species was first described in 1873 by the Finnish lichenologist William Nylander from specimens collected in France. It typically grows on bark, rock, and mossy substrates in shaded, humid forest environments. It is characterised by its cottony texture, weakly developed lobes, and chemical composition including atranorin and stictic acid. Molecular studies have since shown that Lepraria lobificans sensu stricto is genetically distinct from the closely related and more widespread L. finkii, with which it was

Hebeloma sinuosum is a species of agaric fungus in the family Hymenogastraceae. First described as Agaricus sinuosus by Elias Magnus Fries in 1838, it was later transferred to Hebeloma by Lucien Quélet in 1893. It is native to the United Kingdom.

Camarops is a genus of fungi within the Boliniaceae family. The widespread genus contains 19 species.

Tilletia laevis is a plant pathogen that causes bunt on wheat. It was used as a biological weapon by Iraq against Iran during the Iran–Iraq War in the 1980s.

Ramalina intermedia, the rock ramalina, is a species of fruticose lichen in the family Ramalinaceae.

Puccinia mariae-wilsoniae, commonly known as the spring beauty rust, is a species of rust fungus found in North America. A plant pathogen, it grows on the leaves of the spring beauty flowering plants Claytonia caroliniana and C. virginica.

Gymnosporangium clavipes is a plant pathogen, a fungus that causes cedar-quince rust. Similar to Gymnosporangium juniperi-virginianae and Gymnosporangium globosum, the fungus infects a wide range of Rosaceae, such as apple, hawthorn and quince trees, and also requires an evergreen host such as eastern red cedar or a number of other juniper species to complete its life cycle.

Chitonomyces is a genus of fungi in the family Laboulbeniaceae. The genus contain 98 species.

Allophylaria is a genus of fungi in the family Helotiaceae. As of February 2015, the nomenclatural database Index Fungorum lists 14 species in the genus.

Steinia is a genus of lichen-forming fungi in the family Aphanopsidaceae. The genus was established in 1873 by Gustav Wilhelm Körber and contains three recognised species. These lichens grow on disturbed soil and form very thin, powdery crusts that are often barely visible to the naked eye. They produce small, dark brown to black fruiting bodies that contain unusually large numbers of ascospores—up to 16 in each spore-bearing structure.

Pyrenula ochraceoflava is a species of corticolous, crustose lichen in the family Pyrenulaceae. It is a common lowland and coastal species with a pantropical distribution. Its distribution in the Pacific Ocean includes the Caroline Islands, Galápagos Islands, New Caledonia, Tuamotu, and Western Samoa. The lichen was first formally described by Finnish lichenologist William Nylander in 1858 as a species of Verrucaria. Richard Harris transferred it to the genus Pyrenula in 1989. The variety pacifica, found on the Cook Islands (South Pacific Ocean) was proposed by Patrick McCarthy in 2000. It is
