The Stephanosporaceae are a family of fungi in the order Agaricales. Species in the family are gasteroid or corticioid, growing on the ground or on rotting wood or plant debris.

Heimioporus is a genus of fungi in the family Boletaceae. The genus is widely distributed in tropical and subtropical regions, and contains about 15 species. The genus name of Heimioporus is in honour of Roger Jean Heim (1900-1979), who was a French botanist (Mycology) and Director of the National Museum of Natural History, France in Paris. The genus was circumscribed by Egon Horak in Sydowia vol.56 on page 237 in 2004.

Flammulina filiformis, commonly called enoki mushroom, is a species of agaric (gilled mushroom) in the family Physalacriaceae. Until recently, the species was considered to be conspecific with the European Flammulina velutipes, but DNA sequencing has shown that the two are distinct. It is widely cultivated as an edible mushroom in East Asia, where it is included in Japanese and Chinese cuisine.

Verrucospora is a genus of fungi in the family Agaricaceae.

Tympanella galanthina, or cottonbud pouch, is a secotioid fungus in the monotypic genus Tympanella, a member of the Bolbitiaceae family. It is endemic to New Zealand.

Tubosaeta is a genus of fungi in the family Boletaceae. The genus was circumscribed by mycologist Egon Horak in 1967.

Tetrapyrgos is a genus of fungi in the mushroom family Marasmiaceae. The genus has a widespread distribution and contains 16 species.

Cynema is a genus of fungi in the family Tricholomataceae. This is a monotypic genus, containing the single species Cynema alutacea, found in Papua New Guinea.

Crucispora is a genus of fungi in the family Agaricaceae. The genus, described by mycologist Egon Horak in 1971, contains two species found in New Zealand and Asia.

Clavomphalia is a genus of fungi in the family Tricholomataceae. It is a monotypic genus, containing only Clavomphalia yunnanensis, a Chinese species first described by German mycologist Egon Horak in 1987.

Mycena cystidiosa is a species of mushroom in the family Mycenaceae. Described as new to science in 1964, it is known only from New Zealand and Australia. The fruit bodies have a broadly conical small white cap up to 12 mm (0.5 in) wide, with distantly spaced cream-coloured gills on the underside. The stipe is particularly long, up to 20 cm (8 in), with an abundant covering of white hairs at the base. The species is known for its abundant rhizomorphs—long, root-like extensions of mycelia.

Gigasperma is an inactive genus of fungi in the order Agaricales with a single species. It was treated either as the only genus in the monotypic family Gigaspermataceae, or part of the wider Cortinariaceae. Gigasperma was circumscribed by Austrian mycologist Egon Horak in 1971.

Tubaria rufofulva is a species of agaric fungus in the family Tubariaceae. Found in Australia, it was originally described in 1927 by John Burton Cleland as a species of Pholiota. The fungus was transferred to the genus Tubaria in 1983.

Hygrocybe rubrocarnosa is a species of gilled fungi in the genus Hygrocybe, which is commonly known as waxcaps. The species is endemic to New Zealand.

Hygrocybe procera is a species of agaric (gilled mushroom) in the family Hygrophoraceae. First described as Hygrophorus procerus by Greta Stevenson in 1963, the species was transferred to Hygrocybe in 1971 by Egon Horak. It is only known with certainty from New Zealand.

Gymnopilus mesosporus is a species of mushroom in the family Hymenogastraceae.

Gymnopaxillus is a genus of fungi in the family Serpulaceae. According to the Dictionary of the Fungi (10th edition, 2008), the family contains four species found in temperate South America and Australia. Gymnopaxillus was circumscribed by mycologist Egon Horak in 1966 with G. morchelliformis as the type species. G. crubensis, described from Argentina, was added in 1989, while the Australasian species G. nudus and G. vestitus were added to the genus in 2001.

Gliophorus viscaurantius is a species of agaric fungus in the family Hygrophoraceae found in New Zealand.

Gliophorus viridis is a species of agaric fungus in the family Hygrophoraceae found in New Zealand and Australia.

Gliophorus versicolor is a species of agaric fungus in the family Hygrophoraceae. Found in New Zealand, it was described as new to science in 1973 by mycologist Egon Horak. Within the genus Gliophorus, it is classified in the section Glutinosae, a grouping of species characterized by having bright colors, decurrent gills, and a gelatinized subhymenium. Fruit bodies have hemispherical to convex caps typically measuring 20 mm (0.8 in), although some have been recorded up to 50 mm (2.0 in). Moist caps are gluey with a color ranging from reddish brown to pinkish-lilac; the cap margin has radial

Gliophorus lilacipes is a species of agaric fungus in the family Hygrophoraceae. Found in New Zealand, it was described by Egon Horak in 1973.

Gliophorus graminicolor is a species of agaric fungus in the family Hygrophoraceae. It is found in Australia and New Zealand. In 1995, Australian mycologists Tom May and Alec Wood transferred the species to Hygrocybe, but the taxonomic authority Index Fungorum retains it in Gliophorus.
