Families

The Harpellales are an order of fungi classified in the subdivision Kickxellomycotina. Thalli are either unbranched or branched, producing basipetal series of trichospores. Zygospores are biconical. Species in the order are found attached to the gut lining of aquatic larvae of Insecta or (rarely) Isopoda. Harpellales are divided into two families, the Harpellaceae and the Legeriomycetaceae. [1] According to the Dictionary of the Fungi (10th edition, 2008), the order contains 38 genera and 200 species. [2] The order was formally described in 1978 Mycotaxon publication. [3] Harpellales has served as a model to study and understand the evolution, growth, and biodiversity of other such fungi found in the gut as species are plentiful around the world. [4]

Species include Allantomyces zopilotei , Bojamyces olmecensis , Gauthieromyces viviparus and Graminella ophiuroidea . [5]

Agaricales Order of mushrooms

The fungal order Agaricales, also known as gilled mushrooms or euagarics, contains some of the most familiar types of mushrooms. The order has 33 extant families, 413 genera, and over 13,000 described species, along with six extinct genera known only from the fossil record. They range from the ubiquitous common mushroom to the deadly destroying angel and the hallucinogenic fly agaric to the bioluminescent jack-o-lantern mushroom.

Boletales Order of fungi

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, gasteromycetes, and other fruiting-body types.

Boletaceae Family of fungi

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, such as the Cep or King Bolete , highly sought after by mushroom hunters worldwide. 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.

<i>Agaricus</i> Genus of mushrooms

Agaricus is a genus of mushrooms containing both edible and poisonous species, with possibly over 300 members worldwide. The genus includes the common ("button") mushroom and the field mushroom, the dominant cultivated mushrooms of the West.

Hymenochaetales Order of fungi

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.

Clavariaceae Family of fungi

The Clavariaceae are a family of fungi in the order Agaricales. Collectively, they are commonly known as coral fungi due to their resemblance to aquatic coral, although other vernacular names including antler fungi, finger fungi, worm mold, and spaghetti mushroom are sometimes used for similar reasons.

Agaricomycetes Class of fungi

The Agaricomycetes are a class of fungi in the division Basidiomycota. The taxon is roughly identical to that defined for the Homobasidiomycetes by Hibbett & Thorn, with the inclusion of Auriculariales and Sebacinales. It includes not only mushroom-forming fungi, but also most species placed in the deprecated taxa Gasteromycetes and Homobasidiomycetes. Within the subdivision Agaricomycotina, which already excludes the smut and rust fungi, the Agaricomycetes can be further defined by the exclusion of the classes Tremellomycetes and Dacrymycetes, which are generally considered to be jelly fungi. However, a few former "jelly fungi", such as Auricularia, are classified in the Agaricomycetes. According to a 2008 estimate, Agaricomycetes include 17 orders, 100 families, 1147 genera, and about 21000 species. Modern molecular phylogenetic analyses have been since used to help define several new orders in the Agaricomycetes: Amylocorticiales, Jaapiales, Stereopsidales, and Lepidostromatales.

<i>Phallus</i> (fungus) Genus of fungi

The genus Phallus, commonly known as stinkhorns, are a group of basidiomycetes which produce a phallic, often foul-scented, mushroom, from which their name is derived. The genus has a widespread distribution and, according to a 2008 estimate, contains 18 species. They belong to the family Phallaceae in the order Phallales. The best known species is the common stinkhorn.

Rhizophydiales Order of fungi

Rhizophydiales are an important group of chytrid fungi. They are found in soil as well as marine and fresh water habitats where they function as parasites and decomposers.

<i>Melanoleuca</i> Genus of fungi

Melanoleuca is a poorly known genus of saprotrophic mushrooms traditionally classified in the family Tricholomataceae. Most are small to medium sized, white, brown, ocher or gray with a cylindrical to subcylindrical stipe and white to pale yellowish gills. The basidiospores are ellipsoid and ornamented with amyloid warts. Melanoleuca is considered a difficult group to study due to their macroscopic similarities among species and the need of a thorough microscopic analysis to separate species. DNA studies have determined that this genus is closely related to Amanita and Pluteus and that it does not belong to the family Tricholomataceae.

Atheliaceae Family of fungi

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.

Geoglossaceae Family of fungi

Geoglossaceae is a family of fungi in the order Geoglossales, class Geoglossomycetes. These fungi are broadly known as earth tongues. The ascocarps of most species in the family Geoglossaceae are terrestrial and are generally small, dark in color, and club-shaped with a height of 2–8 cm. The ascospores are typically light-brown to dark-brown and are often multiseptate. Other species of fungi have been known to parasitize ascocarps. The use of a compound microscope is needed for accurate identification.

Echinodontiaceae Family of fungi

The Echinodontiaceae are a family of crust fungi in the order Russulales. Species of this family, divided amongst two genera—Echinodontium and Laurilia—have a widespread distribution, although they are especially predominant in north temperate zones. They are parasitic or saprobic on wood, and may cause white rot of angiosperms and gymnosperms.

Orbiliaceae Family of fungi

The Orbiliaceae are a family of saprobic sac fungi in the order Orbiliales. The family, first described by John Axel Nannfeldt in 1932, contains 288 species in 12 genera. Members of this family have a widespread distribution, but are more prevalent in temperate regions. Some species in the Orbiliaceae are carnivorous fungi, and have evolved a number of specialized mechanisms to trap nematodes.

Neopaxillus is a genus of fungi in the family Crepidotaceae. According to the Dictionary of the Fungi, the family contains five species found in Central and South America; a sixth, N. dominicanus, was reported in 2011. It was formerly considered to belong in the family Serpulaceae in the order Boletales, but molecular analysis showed that Neopaxillus is better placed in the Agaricales as a sister group to Crepidotus.

<i>Tuber</i> (fungus)

Tuber is a genus in the Tuberaceae family of fungi, with estimated molecular dating to the end of the Jurassic period. It includes several species of truffles that are highly valued as delicacies.

Smittium is a genus of fungi in the order Harpellales. It is the largest genus in the order. As of 2013, there were 81 described species. Many of these have been formally described only recently; in 1998 there were just 46. Several have been transferred to Smittium from other genera, such as Orphella, Rubetella, Genistella, and Typhella. In general, the genus has a cosmopolitan distribution, but some species are limited to small regions.

Robert W. Lichtwardt was a Brazilian-born American mycologist specializing in the study of arthropod-associated, gut-dwelling fungi (trichomycetes). He is known for his online monograph and interactive keys to trichomycete taxa.

Herpomycetales Order of fungi

The Herpomycetales is an order of fungi within the class Laboulbeniomycetes. The order includes a single dioecious genus, Herpomyces, with 27 accepted species of obligate ectoparasites that are associated exclusively with cockroaches. Like the Laboulbeniales order, they produce cellular thalli. However, the thalli of Herpomyces are developmentally and morphologically unique.
