Fungi named in 1964

Chroogomphus rutilus, commonly known as the brown slimecap or the copper spike, is a species of fungus in the Gomphidiaceae family. First described scientifically as Agaricus rutilus by Jacob Christian Schäffer in 1774, it was transferred to the genus Chroogomphus in 1964 by Orson K. Miller, Jr. The fungus lives ectomycorrhizally with Pinus species, and is found in Europe and North America. The fruit bodies are edible but not highly regarded. Gomphidius viscidus is an old synonym of this mushroom.

Suillus cavipes, commonly known as the hollow foot is a species of mushroom in the genus Suillus. The epithet cavipes (Latin: 'hollow foot') refers to the hollow stem. The brownish cap is up to 12 centimetres (4+3⁄4 in) wide, dry, fibrillose, sometimes with veil remnants on the edge. The pores are buff and usually decurrent. The stipe is up to 9 cm long and 2 cm thick, yellowish above, sometimes with a slight ring, and cap-colored below. The flesh is whitish and firm. It is found in Europe and North America. It is associated with larch in the Pacific Northwest. It is edible.

The Hericiaceae are a family of fungi in the order Russulales. The best known genus is Hericium, species of which are valued for their medicinal properties in Oriental medicine. Taxa are mainly known from north temperate regions, and are saprobic on rotting wood. Phylogenetic analysis suggests that Hericiaceae belongs to the russuloid clade of homobasidiomycetes, and morphological and molecular evidence links it with the families Auriscalpiaceae, Bondarzewiaceae and Echinodontiaceae. Originally proposed in 1961 by Taisiya Lvovna Nikolayeva as a subfamily of Hydnaceae, Hericiaceae was formally

Chroogomphus is a genus of fungi commonly known as pine-spikes or spike-caps, based on the shape of the mushrooms and because they often grow in association with pines. The genus is distributed throughout the Northern Hemisphere, including North America and Eurasia.

Suillus lakei, commonly known as the matte Jack, Lake's bolete, or the western painted Suillus, is a species of fungus in the family Suillaceae. It is characterized by the distinctive reddish-brown tufted fibers or small scales on the cap, and the presence of a woolly veil on the stem. The caps can reach diameters of up to 15 cm (6 in), while the stems are between 6 and 12 cm (2+1⁄4 and 4+3⁄4 in) long and usually 1–3 cm (1⁄2–1+1⁄4 in) thick. On the underside of the cap is a layer of spongy yellow to yellow-brown angular pores; these pores are covered with a whitish partial veil when young. A

Plicaturopsis crispa, the crimped gill or crispling, is a saprotrophic species of fungus in the genus Plicaturopsis that can be found in temperate regions year-round, often on hazel, alder, and beech trees. The fungus has a wide distribution, having been recorded in Europe, Asia, Australia, and North America. In Britain, its range has been rapidly increasing with 78% of all records of P. crispa in the FRDBI (Fungal Records Database of Britain & Ireland) being from after the year 2000, many of which are in areas with no previous recordings of the species.

Suillus pungens, commonly known as the pungent slippery jack or the pungent suillus, is a species of fungus in the genus Suillus. The fruit bodies of the fungus have slimy convex caps up to 14 cm (5+1⁄2 in) wide. The mushroom is characterized by the very distinct color changes that occur in the cap throughout development. Typically, the young cap is whitish, later becoming grayish-olive to reddish-brown or a mottled combination of these colors. The mushroom has a dotted stipe up to 7 cm (2+3⁄4 in) long and 2 cm (3⁄4 in) thick. On the underside on the cap is the spore-bearing tissue,

Plicaturopsis is a genus of fungi in the family Amylocorticiaceae. The genus was circumscribed by English mycologist Derek Reid in 1964. In 2023 P. scarlatina was reclassified to Phlebia making P. crispa the only described species in the genus.

Cudoniella clavus is a species of fungus in the family Helotiaceae. It was first described in 1805 by Johannes Baptista von Albertini and Lewis David de Schweinitz as Peziza clavus. British mycologist R. W. G. Dennis transferred it to Cudoniella in 1964. Fruit bodies of the jelly-like fungus consist of a disc-like cap measuring 0.4–1.2 cm (1⁄8–1⁄2 in) with a thin stipe. They are usually cream in colour, sometimes with hints of ochre or violet. They grow on rotting twigs, stems, leaves, and cones that are submerged in water. Cudoniella clavus is a widespread and common species. It is inedible.

Parmastomyces is a genus of fungi in the family Fomitopsidaceae. The genus was circumscribed by Czech mycologists František Kotlaba and Zdenek Pouzar in 1964, with Tyromyces kravtzevianus Bondartzev & Parm. as the type species. Parmastomyces species cause a brown rot. The genus has a monomitic hyphal system. The genus name of Parmastomyces is in honour of Erast Parmasto (1928–2012), who was an Estonian mycologist, bio-scientist and botanist and onetime director of the Estonian Institute of Zoology and Botany. The genus was circumscribed by Paul Claude Silva in Taxon vol.8 on page 63 in 1959.

Chroogomphus tomentosus, commonly known as the woolly pine spike, is a species of mushroom in the family Gomphidiaceae. It is endemic to western North America.

Aleurocystidiellum is a fungal genus of uncertain familial placement in the order Russulales. The type species, Aleurocystidiellum subcruentatum is a crust fungus that was first described in 1860 by Miles Berkeley and Moses Ashley Curtis. Aleurocystidiellum was circumscribed by Paul Arenz Lemke in 1964.

The Punctulariaceae are a family of fungi in the order Corticiales. The family in its current sense is based on molecular research and contains just three genera of corticioid fungi.

Oudemansiella australis is a species of gilled mushroom in the family Physalacriaceae. It is found in Australasia, where it grows on rotting wood. It produces fruit bodies that are white, with caps up to 5.5 cm (2.2 in) in diameter, attached to short, thick stems.

Entomophaga grylli is a fungal pathogen which infects and kills grasshoppers. It is the causal agent of one of the most widespread diseases affecting grasshoppers. This is sometimes known as summit disease because infected insects climb to the upper part of a plant and grip the tip of the stem as they die; this ensures widespread dispersal of the fungal spores. The fungus is a species complex with several different pathotypes, each one of which seems to be host-specific to different subfamilies of grasshoppers. The pathogen is being investigated for its possible use in biological pest control

Chroogomphus vinicolor, commonly known as the wine-cap Chroogomphus or the pine spike, is a species of mushroom in the family Gomphidiaceae. The fruit bodies have reddish-brown, shiny caps atop tapered stems. The gills are thick, initially pale orange before turning blackish, and extend a short way down the length of the stem. Distinguishing this species from some other similar Chroogomphus species is difficult, as their morphology is similar, and cap coloration is too variable to be a reliable characteristic. C. vinicolor is differentiated from the European C. rutilus and the North American

Calathella is a genus of fungi in the mushroom family Marasmiaceae.

Zoophthora is a genus of fungi in the family Entomophthoraceae. Like other taxa in this family, Zoophthora species cause disease in insects and as such are considered entomopathogenic fungi. Like most entomopathogenic fungal taxa, Zoophthora has been studied largely in the context of biological control of insect pest species. However, recent research indicates that many fungal taxa that have historically been considered entomopathogenic (e.g., Zoophthora) may serve diverse ecological roles as free-living members of the rhizosphere, as endophytes of plant tissue, and as saprobes.

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.

Hydnellum cyanopodium, commonly known as the blue foot or bleeding blue tooth, is an inedible fungus in the family Bankeraceae. It occurs in the Pacific Northwest region of North America.

Hericium abietis, commonly known as the conifer coral hericium, bear's head, or western coral hedgehog, is a species of tooth fungus. It produces a cream white fruit body up to 10–75 cm (4–30 in) tall and wide. The mushroom grows on conifer stumps or logs in North America, fruiting from after the start of the fall rains to mid-season. It is edible.

Conidiobolus coronatus is a saprotrophic fungus, first described by Costantin in 1897 as Boudierella coronata. Though this fungus has also been known by the name Entomophthora coronata, the correct name is Conidiobolus coronatus. C. coronatus is able to infect humans and animals, and the first human infection with C. coronatus was reported in Jamaica in 1965.
