Fungi named in 1973

The Basidiomycota are one of two large divisions that, together with the Ascomycota, constitute the subkingdom Dikarya (often referred to as the "higher fungi") within the kingdom Fungi. Members are known as basidiomycetes. This division includes: agarics, puffballs, stinkhorns, bracket fungi, other polypores, jelly fungi, boletes, chanterelles, earth stars, smuts, bunts, rusts, mirror yeasts, and Cryptococcus, the human pathogenic yeast. Basidiomycota are filamentous fungi composed of hyphae (except for basidiomycota-yeast) and reproduce sexually via the formation of specialized club-shaped

Boletus pinophilus, commonly known as the pine bolete or pinewood king bolete, is a basidiomycete fungus of the genus Boletus. Described by Italian naturalist Carlo Vittadini in 1835, B. pinophilus was for many years considered a subspecies or form of the porcini mushroom B. edulis before genetic studies confirmed its distinct status. In 2008, B. pinophilus in western North America were reclassified as a new species, B. rex-veris. The fungus produces spore-bearing fruit bodies (i.e. mushrooms) above ground under pine trees in summer and autumn. It has a red-brown to maroon-coloured cap and a

Armillaria ostoyae (synonym A. solidipes) is a pathogenic species of fungus in the family Physalacriaceae. It has decurrent gills and the stipe has a ring. The mycelium invades the sapwood of trees, and is able to disseminate over great distances under the bark or between trees in the form of black rhizomorphs ("shoestrings"). In most areas of North America, it can be distinguished from other Armillaria species by its cream-brown colors, prominent cap scales, and a well-developed ring. The species grows and spreads primarily underground, such that the bulk of the organism is not visible from

Rickenella fibula (synonym Omphalina fibula), commonly known as the orange moss navel is a species of fungus belonging to the family Repetobasidiaceae.

Coriolopsis gallica, the brownflesh bracket, is a fungus found growing on decaying wood. It is not associated with any plant disease, therefore it is not considered pathogenic. For various Coriolopsis gallica strains isolated, it has been found, as a common feature of the division Basidiomycota, that they are able to degrade wood components, mainly lignin and to lesser extent cellulose, which results in a degradation area covered by the accumulating white cellulose powder. Therefore, C. gallica might generically be called, as with many other basidiomycetes, a "white-rot" fungus. This feature

Donkioporia is a genus of fungi in the family Fomitopsidaceae. The genus consists of two resupinate (crust-like) species: the type Donkioporia expansa, and D. albidofusca (formerly Poria albidofusca), which was transferred to the genus in 2010. The genus name of Donkioporia is in honour of Marinus Anton Donk (1908–1972), who was a Dutch mycologist. He specialized in the taxonomy and nomenclature of mushrooms. The genus was circumscribed by František Kotlaba and Zdeněk Pouzar in Persoonia Vol.7 on page 214 in 1973.

Auriporia is a small genus of four species of poroid fungi in the family Fomitopsidaceae.

Vanderbylia is a genus of fungi in the family Polyporaceae. It was circumscribed by British mycologist Derek Reid in 1973.

Rickenella is a genus of brightly colored bryophilous (moss inhabiting) agarics in the family Repetobasidiaceae (order Hymenochaetales) that have an omphalinoid morphology. They inhabit patches of moss that grow on soil, tree trunks and logs in temperate regions of the planet. Phylogenetically related agarics are in the genera Contumyces, Gyroflexus, Loreleia, Cantharellopsis and Blasiphalia, as well as the stipitate-stereoid genera Muscinupta and Cotylidia and the clavarioid genus, Alloclavaria. Rickenella is most similar to Contumyces and Blasiphalia, from the former differing by having its

Rectipilus is a genus of cyphelloid fungi in the family Marasmiaceae. The widespread genus contains nine species. It was circumscribed by Reinhard Agerer in 1973.

Texas root rot (also known as Phymatotrichopsis root rot, Phymatotrichum root rot, cotton root rot, or, in the older literature, Ozonium root rot) is a disease that is fairly common in Mexico and the southwestern United States resulting in sudden wilt and death of affected plants, usually during the warmer months. It is caused by a soil-borne fungus named Phymatotrichopsis omnivora that attacks the roots of susceptible plants. It was first discovered in 1888 by Pammel and later named by Duggar in 1916. A monograph of this disease, which includes a historical review, was written by R.B.

Cyptotrama chrysopepla is a small, bright golden yellow, dry cap stalk mushroom. Its gills color ranges from white to yellow. It grows on wood. The cap is convex to flat, often lined or furrowed near the margin and the surface can be dull to powdery or scaly. Gills are either broadly attached or extending down from the stalk. The spore print is white. They can be found in few to many numbers. Its edibility is unknown. Its common name is golden coincap.

Cantharocybe is a genus of mushroom-forming fungi in the family Hygrophoraceae. The genus was described by American mycologists Howard E. Bigelow and Alexander H. Smith in 1973. Cantharocybe contains three species: the type C. gruberi, and C. brunneovelutina from Belize, reported as new to science in 2011, and C. virosa, transferred from "Megacollybia", and found in Bangladesh and India.

Rugosospora is a genus of fungi in the family Agaricaceae. The genus contains two species: R. ochraceobadia, found in Africa, and R. pseudorubiginosa, found in Colombia and Mexico. These species have fruit bodies (mushrooms) with free gills, a white spore print, and a ring on the stipe. Rugosospora was circumscribed by Belgian mycologist Paul Heinemann in 1973.

Gastropila is a genus of fungi in the family Agaricaceae. The genus, described in 1973, contains four puffball-like species distributed in the Americas.

Phaeogalera is a small genus of slender, fleshy bog and swamp-inhabiting mushrooms with large, brownish spores with a germ pore and a hymenium lacking chrysocystidia. Phaeogalera resemble Galerina in their habitat, macroscopic appearance, and spore print color, however, their microscopic characteristics (smooth spores with a distinct germ pore and non-tibiiform cystidia) more closely resemble Psilocybe. The type species, Phaeogalera stagnina, has an Arctic-alpine distribution in the Northern Hemisphere extending into the boreal forests and taiga. It grows along the edges of bogs in peaty

Hypogymnia krogiae, commonly known as the freckled tube lichen, is a species of foliose lichen in the family Parmeliaceae. Found in North America, it was described as a new species in 1973 by Karl Ohlsson. The type specimen was collected near Cheat Bridge, West Virginia by Mason Hale in 1956.
