The Mycenaceae are a family of fungi in the order Agaricales. According to the Dictionary of the Fungi (10th edition, 2008), 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. The extinct genus Protomycena, described from Burdigalian age Dominican amber found on the island of Hispaniola is one of four known

Diaporthaceae is a family of fungal plant pathogens.

Rhodocybe is a genus of fungi in the family Entolomataceae. Basidiocarps (fruit bodies) are agaricoid (gilled mushrooms) producing pink basidiospores that are unevenly roughened or pustular under the microscope. Species are saprotrophic and mostly grow on the ground, occasionally on wood. The genus is distributed worldwide.

Gastroboletus is a genus of fungi in the family Boletaceae. Species in the genus have misshapen caps, poorly developed or absent stipes, and are often buried or partially buried. Gastroboletus has tubes arranged irregularly, rather than vertically as in typical boletes. The edibility of most species is unknown, and those known to be edible are not highly rated.

Abstoma is a genus of gasteroid fungi in the family Agaricaceae. The type species, A. purpureum, was described from New Zealand by mycologist Gordon Herriot Cunningham in 1926. Wright and colleagues transferred A. stuckertii (originally Bovista stuckertii Speg.) to the genus in 1990, but Moreno et al. proposed a new combination Disciseda stuckertii in 2007. A. fimbrialis was described from Baja California, Mexico, in 1992. A. townei is found in western and southwest USA and in west Argentina, while A. reticulatum occurs in Australia and the western and southwestern USA.

Lentinellus ursinus is a species of fungus belonging to the family Auriscalpiaceae. The caps are 2–10 centimetres (1–4 in) wide, often separated into lobes. They are brown in the center, fading to white at the margin. The spore print is white. It may require microscopy to distinguish from L. angustifolius. Lookalikes from other genera include Pleurotus ostreatus. It can be found in North America from October–March on the West Coast and July–October elsewhere. Like all species in its genus, it is inedible due to its bitterness.

Peltigera leucophlebia is a lichenized fungus in the family Peltigeraceae. It is commonly called ruffled freckled pelt. This and other species in the genus contain a green algae in the genus Coccomyxa and also cyanobacteria in the genus Nostoc as symbionts.

Dichostereum is a genus of corticioid fungi in the Peniophoraceae family. Based on 2025 data, the genus contains 14 species that have a widespread distribution. The name was coined with the use of the ancient Greek words δῐ́χᾰ (dĭ́khă, “in two”) + στερεόν (stereón) <στερεός (stereós, “firm; rigid; solid”).

The Coryneliales are an order of ascomycetous fungi within the monotypic subclass Coryneliomycetidae in the class Eurotiomycetes and within the subdivision Pezizomycotina. Species in this order are found almost exclusively in the tropics, primarily as a pathogen on the gymnosperm Podocarpus, although it has been found on other plants like the Southern Hemisphere beech Nothofagus, and Drimys.

Rhodotus is a genus in the fungus family Physalacriaceae. There are two species in the genus with the best known, Rhodotus palmatus, called the netted rhodotus, the rosy veincap, or the wrinkled peach. The unique characteristics of R. palmatus have made it difficult for taxonomists to agree on how it should be classified, resulting in an elaborate taxonomical history and an extensive synonymy. First named Agaricus palmatus by Bulliard in 1785, it was reclassified into several different genera before becoming Rhodotus in 1926. The familial placement of the genus Rhodotus within the order

Diaporthe citri is a plant pathogen infecting citruses.

Aspergillus ustus is a microfungus and member of the division Ascomycota. It is commonly found in indoor environments and soil. Isolated cases of human infection resulting from A. ustus have been described; however the majority of these are nail infections.

Aspergillus flavipes is a species of fungus in the genus Aspergillus. It is from the Flavipedes section. The species was first described in 1926. It has been reported to produce sterigmatocystin, citrinin, and lovastatin.

The Pseudoperisporiaceae are a family of fungi with an uncertain taxonomic placement in the class Dothideomycetes.

The Brachybasidiaceae are a family of fungi in the Basidiomycota, Exobasidiales order. Species in the family have a widespread distribution, especially in tropical and temperate regions of the world. Members of the Brachybasidiaceae are plant pathogens that grow on the leaves of plants such as palms, grasses, sedges, and spiderwort species.

Aspergillus sydowii is a pathogenic fungus that causes several diseases in humans. It has been implicated in the death of sea fan corals (Gorgonia spp.) in the Caribbean Sea.

Teloschistes capensis, commonly known as the Cape hair lichen, is a species of fruticose lichen in the family Teloschistaceae. It is endemic to the Atlantic coast in Namibia and South Africa.

Russula pseudodelica is a mushroom in the genus Russula.

Psilachnum is a genus of fungi within the Hyaloscyphaceae family. The genus contains 27 species.

Ochrolechia africana, commonly known as the frosty saucer lichen, is a species of crustose and corticolous (bark-dwelling) lichen in the family Ochrolechiaceae. It is a widely distributed species, found in tropical and subtropical areas of southern Africa, Asia, Australia, North America, and South America. The lichen is characterized by the presence of a white "frosty" or powdery apothecia.

Hygrocybe nigrescens, commonly known as the blackening wax-cap, is a mushroom of the waxcap genus Hygrocybe. It is found in Europe and Africa. It has been treated as the variety nigrescens of Hygrocybe conica.

Dermatocarpon americanum, the American stippleback lichen, is a silvery-gray, leafy (foliose) lichen with black dots that is common on near seeps in rock faces from southwestern North American deserts to coastal areas. It has a silvery-dusty looking coating. It is common in deserts on vertical rock surfaces that are partially shade protected near seepages. It is umbilicate, meaning it grows from a single anchoring stem called a holdfast), with a single-leaf body (thallus), which ranges in size from 1.7–6 cm. The dusty looking top silvery coating on the cortex is dead fungal filaments (hyphae)

The Cystobasidiaceae are a family of fungi in the order Cystobasidiales. The family currently comprises two genera, both of which contain fungal parasites with auricularioid (laterally septate) basidia, some of which are known only from their yeast states.

Aspergillus sulphureus is a species of fungus belonging to the family Aspergillaceae.

Aspergillus ruber is a species of fungus in the genus Aspergillus. It is from the Aspergillus section. The species was first described in 1929. It has been isolated from coffee beans in the UK, tea and soil in China, and malt dust in the Czech Republic. It has been reported to produce auroglaucin, bisanthrons, catenarin, dihydroauroglaucin, echinulins, epiheveadrides, erythroglaucin, flavoglaucin, isoechinulins, neoechinulins, physcion, questin, questinol, tetracyclic, and tetrahydroauroglaucin.
