The Russulales are an order of the Agaricomycetes,. According to the Dictionary of the Fungi, the order consists of 12 families, 80 genera, and 1767 species. According to Species Fungorum, the order contains 13 families, 117 genera, and 3,060 species.
Nectria is a genus of Ascomycete fungi. They are most often encountered as saprophytes on decaying wood but some species can also occur as parasites of trees, especially fruit trees and a number of other hardwood trees. Some species are significant pests causing diseases such as apple canker, Nectria twig blight, and coral spot in orchards.
The Suillaceae are a family of fungi in the order Boletales, containing the boletus-like Suillus, the small truffle-like Truncocolumella, as well as the monotypic genus Psiloboletinus. As of 2008, there are 54 species in the family. Gastrosuillus, once considered a distinct genus, has been shown with molecular analysis to be a recent evolutionary derivative of Suillus. Fuscoboletinus, described by Pomerleau and Smith in 1962, has also been subsumed into Suillus.
Chaetomium is a genus of fungi in the Chaetomiaceae family. It is a dematiaceous (dark-walled) mold normally found in soil, air, cellulose and plant debris. According to the Dictionary of the Fungi, there are about 95 species in the widespread genus.
The Helvellaceae are a family of ascomycete fungi, the best-known members of which are the elfin saddles of the genus Helvella. Originally erected by Elias Magnus Fries in 1823 as Elvellacei, it contained many genera. Several of these, such as Gyromitra and Discina, have been found to be more distantly related in a molecular study of ribosomal DNA by mycologist Kerry O'Donnell in 1997, leaving a much smaller core clade now redefined as Helvellaceae. Instead, this narrowly defined group is most closely related to the true truffles of the Tuberaceae. Although the Dictionary of the Fungi considered the Helvellaceae to contain six genera and 63 species, genetic analysis has shown that Leucangium, previously classified in this family, is more closely related to the Morchellaceae.
Sowerbyella is a genus of fungi in the family Pyronemataceae. The genus has a widespread distribution, and contains 17 species found mostly in Europe and China.
Mutinus is a genus of fungi in the family Phallaceae. The genus was first described by Elias Magnus Fries in 1849. According to the Dictionary of the Fungi, the widespread genus contains 12 species.
Scutellinia scutellata, commonly known as the eyelash cup, the Molly eye-winker, the scarlet elf cap, the eyelash fungus or the eyelash pixie cup, is a small saprophytic fungus of the genus Scutellinia. It is the type species of Scutellinia, as well as being the most common and widespread. The fruiting bodies are small red cups with distinct long, dark hairs or "eyelashes". These eyelashes are the most distinctive feature and are easily visible with a magnifying glass. The species is common in North America and Europe, and has been recorded on every continent. S. scutellata is found on rotting wood and in other damp habitats, typically growing in small groups, sometimes forming clusters. It is sometimes described as inedible, but its small size means it is not suitable for culinary use. Despite this, it is popular among mushroom hunters due to its unusual "eyelash" hairs, making it memorable and easy to identify.
The Mycenaceae are a family of fungi in the order Agaricales. According to the Dictionary of the Fungi, 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.
Lecidea is a genus of crustose lichens with a carbon black ring or outer margin (exciple) around the fruiting body disc (apothecium), usually found growing on (saxicolous) or in (endolithic) rock. Lichens that have such a black exciple are called lecideine, meaning "like Lecidea, even if they are not in this genus. Members of the genus are commonly called disk lichens or tile lichens.
Calathella is a genus of fungi in the mushroom family Marasmiaceae. According to the Dictionary of the Fungi, the genus contains nine species found in Europe and North America. The genus was circumscribed by the English mycologist Derek Reid in 1964.
Phillipsia is a genus of fungi in the family Sarcoscyphaceae. There are about 17 species in the genus, which collectively have a widespread distribution in subtropical and tropical areas. The genus was circumscribed by Miles Joseph Berkeley in 1881. The generic name honours Wales-born English botanist William Phillips (1822–1905).
Leucangium is a genus of ascomycete fungi. The genus was circumscribed by French mycologist Lucien Quélet in 1883. Although classified in the Helvellaceae in the past, molecular analysis indicates it is closely related to the genus Fischerula and Imaia, and therefore must be placed in the Morchellaceae. The genus includes two species, Leucangium ophthalmosporum Quél. and L. carthusianum Paol., and both of them produce sequestrate ascoma, globose to ellipsoidal ascus, and dark olive-colored to grayish green, smooth, fusiform ascospores.
Sphaerophorus a genus of lichenized fungi in the order Lecanorales.
Scutellinia olivascens is a species of apothecial fungus belonging to the family Pyronemataceae. This European fungus forms clusters of orange discs up to 1.5 cm in diameter on soil or rotting wood in summer and autumn. It is very similar to the common species Scutellinia umbrorum and can only be reliably identified by microscopic features.
Scutellinia umbrorum is a species of apothecial fungus belonging to the family Pyronemataceae. This is a common European species, forming clusters of orange discs up to 1.5 cm in diameter on soil or rotting wood in summer and autumn. It is very similar to congeners such as Scutellinia olivascens and can only be reliably identified by microscopic features. S. umbrorum is inedible.
Richard Paul "Dick" Korf was an American mycologist and founding co-editor of the journal Mycotaxon. He was a preeminent figure in the study of discomycetes and made significant contributions to the field of fungal nomenclature and taxonomy. Korf was professor emeritus of mycology at Cornell University and director emeritus of Cornell University's Plant Pathology Herbarium.
