Rolf Singer was a German mycologist and taxonomist of gilled mushrooms (agarics).
The Mycenaceae are a family of fungi in the order Agaricales. According to the Dictionary of the Fungi, the family contains 10 genera and 705 species. This is one of several families that were separated from the Tricholomataceae as a result of phylogenetic analyses. Taxa in the Mycenaceae are saprobic, have a cosmopolitan distribution, and are found in almost all ecological zones. The family was circumscribed by Caspar van Overeem in 1926.
Oudemansiella is a genus of fungi in the family Physalacriaceae. The genus contains about 15 species that are widely distributed in tropical and temperate regions. Yang and colleagues revised the genus in a 2009 publication, describing several new species and several varieties. They classified species in the genus into four sections based on the structure of the cap cuticle: Oudemansiella, Mucidula, Dactylosporina, and Radicatae.
Metrodia is a genus of fungi in the family Agaricaceae. It was circumscribed in 1971 by mycologist Jörg H. Raithelhuber, with M. collybioides as the type species. M. excissa was added to the genus in 1983.
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.
Robert Kühner was a French mycologist most notable for reviewing many forms of agaric genera.
Mycena adscendens, commonly known as the frosty bonnet, is a species of fungus in the family Mycenaceae. The fungus produces small white fruit bodies (mushrooms) with caps up to 7.5 mm (0.3 in) in diameter that appear to be dusted with sugar-like granules. Caps are supported by thin, hollow stems up to 20 mm (0.8 in) long, which are set on a disc-like base. Its distribution includes Europe, Turkey and the Pacific coast of the United States. The fruit bodies grow on fallen twigs and other woody debris on the forest floor, including fallen hazel nuts. The variety carpophila is known from Japan. There are several small white Mycena species that are similar in appearance to M. adscendens, some of which can be reliably distinguished only by examining microscopic characteristics.
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.
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.
Haasiella is a fungal genus in the family Hygrophoraceae. It is a monotypic genus that contains only the species Haasiella splendidissima. Haasiella venustissima, formerly considered to be a distinct species based on its one and two-spored basidia, was found by a DNA study to be synonymous with H. splendidissima. H. splendidissima is only known from Europe and is saprotrophic on wood. Haasiella was described as a new genus in 1966 by Czech mycologists František Kotlaba and Zdeněk Pouzar. It is most closely related to the genus Hygrophorus.
Rimbachia is a genus of fungi in the family Tricholomataceae. The genus contains about ten species with a widespread distribution in tropical regions.
Henningsomyces is a genus of fungi in the family Marasmiaceae.
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.
Cunninghammyces is a genus of corticioid fungi in the family Cyphellaceae. The genus, described by Joost Stalpers in 1985, contains two species known from New Zealand and Réunion.
David Norman Pegler is a British mycologist. Until his retirement in 1998, he served as the Head of Mycology and assistant keeper of the herbarium at the Royal Botanic Gardens in Kew. Pegler received his BSc from London University in 1960, thereafter studying tropical Agaricales with R.W.G. Dennis as his graduate supervisor. He earned a master's degree in 1966, and a PhD in 1974. His graduate thesis was on agarics of east Africa, later published as A preliminary agaric flora of East Africa in 1977. In 1989, London University awarded him a DSc for his research into the Agaricales.
