Rimbachia is a genus of fungi in the family Tricholomataceae. The genus contains about ten species with a widespread distribution in tropical regions. [1]
The genus name of Rimbachia is in honour of August Rimbach (1862–1943), who was a German botanist (Bryology). He was between 1910-1919, Professor of Botany at the Agronomic Institute in Montevideo, Uruguay. [2]
The genus was circumscribed by Narcisse Théophile Patouillard in Bull. Soc. Mycol. France vol.7 on page 159 in 1891.

Rolf Singer was a German-born mycologist and one of the most important taxonomists of gilled mushrooms (agarics) in the 20th century.
The Tricholomataceae are a large family of fungi within the order Agaricales. Originally a classic "wastebasket taxon", the family included any white-, yellow-, or pink-spored genera in the Agaricales not already classified as belonging to e.g. the Amanitaceae, Lepiotaceae, Hygrophoraceae, Pluteaceae, or Entolomataceae.
Lichenomphalia is both a basidiolichen and an agaric genus. Most of the species have inconspicuous lichenized thalli that consist of scattered, small, loose, nearly microscopic green balls or foliose small flakes containing single-celled green algae in the genus Coccomyxa, all interconnected by a loose network of hyphae. The agaric fruit bodies themselves are nonlichenized and resemble other types of omphalinoid mushrooms. These agarics lack clamp connections and do not form hymenial cystidia. The basidiospores are hyaline, smooth, thin-walled, and nonamyloid. Most of the species were originally classified in the genera Omphalina or Gerronema. Historically the species were classified with those other genera in the family, the Tricholomataceae together with the nonlichenized species. Lichenomphalia species can be grouped into brightly colored taxa, with vivid yellow and orange colors, versus the grey brown group, depending upon the microscopic pigmentation deposits. Molecular research comparing DNA sequences now place Lichenomphalia close to the redefined genus Arrhenia, which together with several other genera not traditionally considered to be related, fall within the newly redefined Hygrophoraceae.
Favolaschia is a genus of fungi in the family Mycenaceae. The genus has a widespread distribution, and contains about 50 species. Like the genus Favolus, the name is derived from the Latin favus meaning honeycomb, as the fungi with the large pores on the underside are resembling a honeycomb. The name was first published as a section of the obsolete genus Laschia, which was named after Wilhelm Gottfried Lasch (1787-1863), who was a German apothecary and botanist.
Montagnea is a genus of fungi in the family Agaricaceae. The genus has a widespread distribution in subtropical dry areas, and contains six species. Montagnea was circumscribed by Swedish mycologist Elias Magnus Fries in 1836.
Ripartitella is a genus of fungi in the family Agaricaceae. The genus was circumscribed by Rolf Singer in Mycologia vol.39 on page 85 in 1947.
Pegleromyces is a genus of fungi in the family Tricholomataceae. It is a monotypic genus, containing the single species Pegleromyces collybioides, found in Brazil, and described as new to science by mycologist Rolf Singer in 1981.
Descolea is a genus of fungi in the family Bolbitiaceae. Described by mycologist Rolf Singer in 1952, the widespread genus contains about 15 species. It was formerly placed in the family Cortinariaceae because of its limoniform basidiospores and its ectomycorrhizal lifestyle. A 2013 molecular phylogenetics study by Tóth et al. found it to be closely related to the genus Pholiotina The genus Pseudodescolea, erected for the single Descolea-like species Pseudodescolea lepiotiformis, was formerly considered distinct until a 1990 study found it to be a synonym of Descolea antarctica.
Rhodoarrhenia is a genus of fungi in the family Bolbitiaceae. Most species of the genus Rhodoarrhenia have a tropical or subtropical distribution. The genus was circumscribed by mycologist Rolf Singer in 1963. He made R. pezizoidea the type species; in its taxonomic history, this fungus had been placed in the genera Merulius, Campanella, Rimbachia, and Arrhenia by various authors.
Dennisiomyces is a genus of fungi in the family Tricholomataceae. Described by mycologist Rolf Singer in 1955, the genus contains five species found in South America.
Pseudoomphalina is a genus of fungi in the placed in the family Tricholomataceae for convenience. The genus contains six species that are widespread in northern temperate areas. Pseudoomphalina was circumscribed by Rolf Singer in 1956. Pseudoomphalina was found to be paraphyletic to Neohygrophorus in a molecular phylogenetics study and since Pseudoomphalina is an older name, Neohygrophyorus was synonymized with it. The type species of Neohygrophorus was Neohygrophorus angelesianus, now Pseudoomphalina angelesiana. In earlier classifications based on anatomy prior to DNA sequence-based classifications, its unusual combination of features led taxonomists to independently create two subgenera in two genera: Hygrophorus subg. Pseudohygrophorus and Clitocybe subg. Mutabiles; the latter based on Neohygrophorus angelesianus but described under a new species name which is now placed in synonymy, Clitocybe mutabilis. All species of Pseudoomphalina are united by the presence of clamp-connections in their hyphae, an interwoven gill trama and amyloid spores. Pseudoomphalina angelesiana possesses grey-violaceous pigments that turn red in alkali solutions and lacks filiform, hyphal sterile elements in its hymenium and stipitipellis. These were features used to distinguish it from Pseudoomphalina as a genus, but Pseudoomphalina umbrinopurpurascens possesses these same pigments and the filiform elements of Pseudoomphalina. Molecular phylogenetics studies have also found some former species of Pseudoomphalina to belong in other genera. Pseudoomphalina pachyphylla was moved to its own genus, Pseudolaccaria, and Pseudoomphalina clusiliformis was synonymized with it. Pseudoomphalina flavoaurantia and Pseudoomphalina lignicola were found to belong in Clitocybula. Phylogenetically, Pseudoomphalina is in a tricholomatoid clade but not in the Tricholomataceae.
Ripartites is a genus of fungi in the family Tricholomataceae. The genus has a widespread distribution and originally contained five species. Species in Ripartites have small, round to subglobose spores, which are yellowish-brown and ornamented. Macroscopically, they resemble Clitocybe. Ripartites was circumscribed by Petter Karsten in 1879.
Skepperiella is a genus of fungus in the family Marasmiaceae. The widespread genus contains four species. The genus was circumscribed by Albert Pilát in Bull. Soc. Mycol. France vol.43 on page 56 in 1927.
Skepperia is a genus of fungi in the family Thelephoraceae. The genus was described by mycologist Miles Joseph Berkeley in 1857 to contain the type species Skepperia convoluta. The genus was circumscribed by Berkeley in Trans. Linn. Soc. London vol.22 on page 130 in 1857.
Semiomphalina is a basidiolichen genus in the family Hygrophoraceae. The genus is monotypic, containing the single species Semiomphalina leptoglossoides, found in Papua New Guinea.
Carlo Luigi Spegazzini, in Spanish Carlos Luis Spegazzini, was an Italian-born Argentinian botanist and mycologist.
Setchelliogaster is a genus of fungi in the order Agaricales. It is incertae sedis with respect to familial placement within the order, although Kirk and colleagues consider it likely aligned with either the Bolbitiaceae or the Cortinariaceae. Species Fungorum class it as in the Bolbitiaceae family. The genus is widespread in warm, dry areas, originally containing five species, later degraded to 3 species. It was circumscribed by Czech mycologist Zdeněk Pouzar in 1958.
Saproamanita nauseosa is a species of agaric fungus in the family Amanitaceae. First described by English mycologist Elsie Maud Wakefield in 1918 as a species of Lepiota, it was named for its nauseating odor. The type specimen was found growing on soil in the Nepenthes greenhouse at Kew Gardens. Derek Reid transferred the species to Amanita in 1966, and then in 2016 the separate genus Saproamanita was created by Redhead et al. for saprophytic Amanitas and it was transferred to this new genus.
