Taxa named by Rolf Singer

Macrolepiota is a genus of white spored, gilled mushrooms of the family Agaricaceae. The best-known member is the parasol mushroom (M. procera). The widespread genus contains about 40 species.

The Strophariaceae are a family of fungi in the order Agaricales. Under an older classification, the family covered 18 genera and 1316 species. The species of Strophariaceae have red-brown to dark brown spore prints, while the spores themselves are smooth and have an apical germ pore. These agarics are also characterized by having a cutis-type pileipellis. Ecologically, all species in this group are saprotrophs, growing on various kinds of decaying organic matter. The family was circumscribed in 1946 by mycologists Rolf Singer and Alexander H. Smith.

The Bolbitiaceae are a family of mushroom-forming basidiomycete fungi. A 2008 estimate placed 17 genera and 287 species in the family. Bolbitiaceae was circumscribed by mycologist Rolf Singer in 1948.

The genus was described in 1944 by mycologists Appollinaris Semenovich Bondartsev and Rolf Singer to contain the type, and at that time, sole species, A. lapponicus. A. unicolor was transferred to the genus (from Tyromyces) in 2003. The generic name Amylocystis is derived from the Ancient Greek words ("starch") and ("bladder").

Xanthoconium is a genus of bolete fungi in the family Boletaceae. It was circumscribed by mycologist Rolf Singer in 1944, who included Boletus affinis and what was then known as Gyroporus stramineus as the type species. These two species were part of the "strange group of species described by Murrill and Snell as white-spored Gyropori, and separated by the latter under the new generic name Leucogyroporus." C.B. Wolfe described three species from the United States in 1987: X. chattoogaense, Xanthoconium montaltoense, and X. montanum. , the nomenclatural database Index Fungorum list se

Cheimonophyllum is a genus of fungi in the family Cyphellaceae. The widely distributed genus contains three species.

Callistosporium is a genus of fungi in the order Agaricales. Basidiocarps (fruit bodies) are agarics (gilled mushrooms), either with a central stipe (stalk) or pleurotoid (with a lateral stipe). The latter group were formerly referred to Pleurocollybia. Recent molecular research, based on cladistic analysis of DNA sequences, has shown that the genus is a natural, monophyletic grouping, though not all species have yet been sequenced. Species are saprotrophic, typically growing on wood, and the genus is found worldwide.

Epicnaphus is a genus of mushroom-forming fungi in the family Marasmiaceae. The genus, circumscribed by mycologist Rolf Singer in 1960, contains two species found in South America. Fruitbodies of Epicnaphus species are similar in appearance to those in Marasmius section Sicci, but have a smooth hymenium and broom cells of the Rotalis-type. Singer initially included only the type species, E. phalaropus, which was originally collected from fallen branches in a Bolivian rainforest. The Argentinian species E. longispora was added to the genus by Jörg Raithelhuber in 1973.

Hemipholiota is a genus of agaric fungi in the order Agaricales. It was originally proposed by Rolf Singer in 1962 as a subgenus of Pholiota to contain species with absent or sparse pleurocystidia and absent chrysocystidia. Henri Romagnesi raised it to generic status in 1980, but this naming was invalid as it did not meet the requirements of the International Code of Nomenclature for algae, fungi, and plants. Marcel Bon published the genus validly in 1986.

Hiatulopsis is a genus of two species of fungi in the family Agaricaceae. The genus was circumscribed in 1967 by mycologists K. Grinling and Rolf Singer with H. amara as the type species. H. aureoflava was added to the genus by Singer in 1989.

Smithiomyces is a genus of fungi in the family Agaricaceae. It was circumscribed by Rolf Singer in 1944. The type species, S. mexicanus, was formerly placed in Amanita, as well as the now obsolete genera Leucomyces and Venenarius. The genus was named to honor American mycologist Alexander H. Smith.

Nivatogastrium is a genus of secotioid fungi in the family Strophariaceae. The genus has contained four species found in North America and New Zealand, but the type species, Nivatogastrium nubigenum, is now considered to be a gasteroid species of Pholiota, and was transferred to that genus in 2014.

Pachylepyrium is a genus of fungi in the family Tubariaceae. The genus was circumscribed by Rolf Singer in 1958. The genus Pachylepyrium is widespread in northern temperate areas. Some species of Pachylepyrium have been moved to the genus Crassisporium.

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.

Porpoloma is a genus of fungi in the family Tricholomataceae. The genus contains about 12 species found predominantly in South America. Porpoloma was described by mycologist Rolf Singer in 1952 with P. sejunctum as the type species.

Neopaxillus is a genus of fungi in the family Crepidotaceae. According to the Dictionary of the Fungi (10th edition, 2008), the family contains five species found in Central and South America; a sixth, N. dominicanus, was reported in 2011. It was formerly considered to belong in the family Serpulaceae in the order Boletales, but molecular analysis showed that Neopaxillus is better placed in the Agaricales as a sister group to Crepidotus (of the family Crepidotaceae).

Pseudoomphalina is a genus of fungi 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

Neosecotium is a genus of fungi in the family Agaricaceae. The genus was circumscribed in 1960 by American mycologists Rolf Singer and Alexander H. Smith. The type species, N. macrosporum, previously only known from the US, was recorded in Mexico in 2012.
