The Omphalotaceae are a family of fungi in the order Agaricales. Basidiocarps (fruit bodies) are most frequently agarics (gilled mushrooms), but occasionally corticioid (in the genus Brunneocorticium ) [1] or poroid (in the genus Hymenoporus ). [2]
The family was originally described in 1985 by German mycologist Andreas Bresinsky to accommodate the genus Omphalotus (including Lampteromyces) based on anatomical and morphological characters which he considered distinctive. He placed the family within the Boletales. [3] Subsequent molecular research, based on cladistic analysis of DNA sequences, indicated, however, that Omphalotus belonged within the Agaricales. [4] Moreover, the genus formed a monophyletic clade with a much larger group of fungi, many of which were formerly placed in the Marasmiaceae. The earliest name for this clade is the Omphalotaceae. [4] [5]
The Agaricales are an order of fungi in the division Basidiomycota. As originally conceived, the order contained all the agarics, but subsequent research has shown that not all agarics are closely related and some belong in other orders, such as the Russulales and Boletales. Conversely, DNA research has also shown that many non-agarics, including some of the clavarioid fungi and gasteroid fungi belong within the Agaricales. The order has 46 extant families, more than 400 genera, and over 25,000 described species, along with six extinct genera known only from the fossil record. Species in the Agaricales range from the familiar Agaricus bisporus and the deadly Amanita virosa to the coral-like Clavaria zollingeri and bracket-like Fistulina hepatica.
The Boletales are an order of Agaricomycetes containing over 1300 species with a diverse array of fruiting body types. The boletes are the best known members of this group, and until recently, the Boletales were thought to only contain boletes. The Boletales are now known to contain distinct groups of agarics, puffballs, and other fruiting-body types.
The Boletaceae are a family of mushroom-forming fungi, primarily characterised by small pores on the spore-bearing hymenial surface, instead of gills as are found in most agarics. Nearly as widely distributed as the agarics, the family is renowned for hosting some prime edible species highly sought after by mushroom hunters worldwide, such as the cep or king bolete . A number of rare or threatened species are also present in the family, that have become the focus of increasing conservation concerns. As a whole, the typical members of the family are commonly known as boletes.
The Hymenochaetales are an order of fungi in the class Agaricomycetes. The order in its current sense is based on molecular research and not on any unifying morphological characteristics. According to one 2008 estimate, the Hymenochaetales contain around 600 species worldwide, mostly corticioid fungi and poroid fungi, but also including several clavarioid fungi and agarics. Species of economic importance include wood decay fungi in the genera Phellinus and Inonotus sensu lato, some of which may cause losses in forestry. Therapeutic properties are claimed for Inonotus obliquus ("chaga") and Phellinus linteus, both of which are now commercially marketed.
The Hygrophoraceae are a family of fungi in the order Agaricales. Originally conceived as containing white-spored, thick-gilled agarics, including Hygrophorus and Hygrocybe species, DNA evidence has extended the limits of the family, so it now contains not only agarics, but also basidiolichens and corticioid fungi. Species are thus diverse and are variously ectomycorrhizal, lichenized, associated with mosses, or saprotrophic. The family contains 34 genera and over 1000 species. None is of any great economic importance, though fruit bodies of some Hygrocybe and Hygrophorus species are considered edible and may be collected for sale in local markets.
The Tricholomataceae are a large family of fungi within the order Agaricales. Originally a classic "wastebasket taxon", the family included any white-, yellow-, or pink-spored genera in the Agaricales not already classified as belonging to e.g. the Amanitaceae, Lepiotaceae, Hygrophoraceae, Pluteaceae, or Entolomataceae.
Omphalotus is a genus of basidiomycete mushroom, in the family Omphalotaceae, formally circumscribed by Victor Fayod in 1889. Members have the traditional cap and stem structure. They are saprobic, and fruit in clumps on the ground, adjacent to host trees. The best known and type species is the jack-o'-lantern mushroom (Omphalotus olearius). Species of Omphalotus have been mistaken for chanterelles. All Omphalotus species are presumed poisonous, causing gastrointestinal symptoms. Some Omphalotus species have bioluminescent properties.
Loreleia is a genus of brightly colored agarics in the Hymenochaetales that have an omphalinoid morphology. They inhabit mosses and or liverworts on soil in temperate regions of the Northern Hemisphere. Phylogenetically related agarics are in the genera Contumyces, Gyroflexus, Rickenella, Cantharellopsis and Blasiphalia, as well as the stipitate-stereoid genera Muscinupta and Cotylidia and the clavaroid genus, Alloclavaria. However, the large number of DNA base-pair changes causes a long-branch to form in phylogenetic analyses depicted as cladograms.
Atheliaceae is a family of corticioid fungi placed under the monotypic order Atheliales. Both the order and the family were described by Walter Jülich in 1981. According to a 2008 estimate, the family contains 20 genera and approximately 100 species. However, many genera formerly considered to belong in the Atheliaceae have since been moved to other families, including Amylocorticiaceae, Albatrellaceae, and Hygrophoraceae. Despite being a relatively small group with inconspicuous forms, Atheliaceae members show great diversity in life strategies and are widespread in distribution. Additionally, being a group strictly composed of corticioid fungi, they may also provide insights on the evolution of fruiting body forms in basidiomycetes.
The Physalacriaceae are a family of fungi in the order Agaricales. Species in the family have a widespread distribution, ranging from the Arctic, (Rhizomarasmius), to the tropics, e.g. Gloiocephala, and from marine sites (Mycaureola) and fresh waters (Gloiocephala) to semiarid forests (Xerula).
Hygrophoropsis is a genus of gilled fungi in the family Hygrophoropsidaceae. It was circumscribed in 1888 to contain the type species, H. aurantiaca, a widespread fungus that, based on its appearance, has been affiliated with Cantharellus, Clitocybe, and Paxillus. Modern molecular phylogenetic analysis shows that the genus belongs to the suborder Coniophorineae of the order Boletales.
Rhizomarasmius is a genus of fungi in the family Physalacriaceae, containing about five species.
Infundibulicybe is a genus of fungi that is robustly placed incertae sedis as sister group to the Tricholomatoid clade. It has previously been part of the family of Tricholomataceae, but recent molecular phylogeny has shown it to take an isolated position within the Agaricales.
Marasmiellus is a genus of fungi in the family Omphalotaceae. The widespread genus, circumscribed by American mycologist William Murrill in 1915, contains over 250 species. The name comes from the Greek marasmus meaning wasting.
Podoserpula is a genus of fungi in the family Amylocorticiaceae. The genus contains six species including the type species, P. pusio, commonly known as the pagoda fungus. Species of the genus Podoserpula produce fruit bodies consisting of up to a dozen caps arranged in overlapping shelves, attached to a central axis. Its unique shape is not known to exist in any other fungi. The genus is known to occur in Australia and New Zealand, Venezuela, Madagascar, and New Caledonia.
Brunneocorticium is a genus of fungi which following DNA analysis has been placed in the family Omphalotaceae. The genus, described in 2007, contains two corticioid species and one species which does not seem to have any fruiting body.
Aphroditeola is an agaric fungal monotypic genus that produces pink cantharelloid fruit bodies on coniferous forest floors. The lamellae are forked and typically the fruit bodies have a fragrant odor described as candy-like, cinnamon-like or pink bubble gum-like.
The Porotheleaceae are a family of saprotrophic, mainly wood-decay fungi in the order Agaricales that are primarily agarics, but also include cyphelloid fungi. The family had been informally cited in the literature as the 'hydropoid' clade. The type genus, Porotheleum, was placed in the phylogenetically defined clade in 2002 but the clade was more strongly supported in 2006 though without including Porotheleum. Its sister group is the Cyphellaceae, both in the 'marasmioid clade'. Some included taxa are cultivated by ants. More recently the family was recognized in three analyses that included Porotheleum.
