Genera incertae sedis

The Pezizales are an order of the subphylum Pezizomycotina within the phylum Ascomycota. The order contains 16 families, 199 genera, and 1683 species. [1] It contains a number of species of economic importance, such as morels, the black and white truffles, and the desert truffles. The Pezizales can be saprobic, mycorrhizal, or parasitic on plants. Species grow on soil, wood, leaves and dung. Soil-inhabiting species often fruit in habitats with a high pH and low content of organic matter, including disturbed ground. Most species occur in temperate regions or at high elevation. Several members of the Sarcoscyphaceae and Sarcosomataceae are common in tropical regions.

Description

Members of this order are characterized by asci that typically open by rupturing to form a terminal or eccentric lid or operculum. The ascomata are apothecia or are closed structures of various forms derived from apothecia. Apothecia range in size from less than a millimeter to approximately 15 cm, and may be stalked or sessile. The order includes epigeous, semihypogeous to hypogeous (truffles) taxa. The ascospores are single-celled, bipolar symmetrical, and usually bilaterally symmetrical, ranging from roughly spherical to ellipsoidal to occasionally fusoid. [2] The ascospores of some species develop surface ornamentations such as warts, ridges, or spines. The tissues of the ascomata are fleshy and often fragile. Although the majority of species are known only in the teleomorphic state, the anamorphs of some species are known.

Taxonomy

A phylogenetic analysis of molecular and morphological data suggests that there are three lineages within Pezizales. [3] Lineage A includes Ascobolaceae and Pezizaceae. The former has no known hypogeous species. Lineage B includes the two epigeous families Rhizinaceae and Caloscyphaceae, as well as two sub-lineages with known hypogeous species, MorchellaceaeDiscinaceae and HelvellaceaeTuberaceae. Lineage C include Ascodesmidaceae, Sarcoscyphaceae, Sarcosomataceae with no known hypogeous species as well as Glaziellaceae and Pyronemataceae. It is unknown where Carbomycetaceae fits into this lineage.

<span class="mw-page-title-main">Secotioid</span> Type of fungi

Secotioid fungi are an intermediate growth form between mushroom-like hymenomycetes and closed bag-shaped gasteromycetes, where an evolutionary process of gasteromycetation has started but not run to completion. Secotioid fungi may or may not have opening caps, but in any case they often lack the vertical geotropic orientation of the hymenophore needed to allow the spores to be dispersed by wind, and the basidiospores are not forcibly discharged or otherwise prevented from being dispersed —note—some mycologists do not consider a species to be secotioid unless it has lost ballistospory.

An ascocarp, or ascoma, is the fruiting body (sporocarp) of an ascomycete phylum fungus. It consists of very tightly interwoven hyphae and millions of embedded asci, each of which typically contains four to eight ascospores. Ascocarps are most commonly bowl-shaped (apothecia) but may take on a spherical or flask-like form that has a pore opening to release spores (perithecia) or no opening (cleistothecia).

<span class="mw-page-title-main">Truffle</span> Fruiting body of a subterranean ascomycete fungus

A truffle is the fruiting body of a subterranean ascomycete fungus, predominantly one of the many species of the genus Tuber. In addition to Tuber, over one hundred other genera of fungi are classified as truffles including Geopora, Peziza, Choiromyces, and Leucangium. These genera belong to the class Pezizomycetes and the Pezizales order. Several truffle-like basidiomycetes are excluded from Pezizales, including Rhizopogon and Glomus. Truffles are ectomycorrhizal fungi, so they are usually found in close association with tree roots. Spore dispersal is accomplished through fungivores, animals that eat fungi. These fungi have significant ecological roles in nutrient cycling and drought tolerance.

<span class="mw-page-title-main">Boletales</span> 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, puffballs, and other fruiting-body types.

<i>Sarcoscypha</i> Genus of fungi

Sarcoscypha is a genus of ascomycete fungus and a type genus of the family Sarcoscyphaceae. Species of Sarcoscypha are present in Europe, North America and tropical Asia. They are characterised by a cup-shaped apothecium which is often brightly coloured. They have had a range of popular uses, one of which was as a table decoration. Some members of the family such as S. coccinea and the - according to new knowledge - more common S. austriaca in western Europe and United States have bright scarlet apothecia which have given them familiar names such as the scarlet cup fungus and scarlet elf cap.

<i>Gyromitra</i> Genus of fungi

Gyromitra is a genus of about 18 species of ascomycete fungi. They are a false morel - a frequently toxic mushroom that can be mistaken for edible mushrooms of the genus Morchella (morels).

The sporocarp of fungi is a multicellular structure on which spore-producing structures, such as basidia or asci, are borne. The fruitbody is part of the sexual phase of a fungal life cycle, while the rest of the life cycle is characterized by vegetative mycelial growth and asexual spore production.

<span class="mw-page-title-main">Hymenogastraceae</span> Family of fungi

The Hymenogastraceae is a family of fungi in the order Agaricales with both agaric and false-truffle shaped fruitbodies. Formerly, prior to molecular analyses, the family was restricted to the false-truffle genera. The mushroom genus Psilocybe in the Hymenogastraceae is now restricted to the hallucinogenic species while nonhallucinogenic former species are largely in the genus Deconica classified in the Strophariaceae.

<span class="mw-page-title-main">Discinaceae</span> Family of fungi

The Discinaceae are a family of ascomycete fungi, the best known members of which are the false morels of the genus Gyromitra. Originally erected by Erich Heinz Benedix in 1961, it was found to be a discrete clade in a molecular study of ribosomal DNA by mycologist Kerry O'Donnell in 1997. As of 2008, the family is thought to contain 5 genera and 58 species. As of 2022, the GBIF accepts Discina(Fr.) Fr., Gymnohydnotrya B.C.Zhang & Minter, 1989, GyromitraFr., 1849, HydnotryaBerk. & Broome and Maublancomyces. But calls NeogyromitraS.Imai and PseudorhizinaJacz. doubtful.

<span class="mw-page-title-main">Morchellaceae</span> Family of fungi

The Morchellaceae are a family of ascomycete fungi in the order Pezizales. According to a standard reference work, the family has contained at least 49 species distributed among four genera. However, in 2012, five genera that produce ascoma that are sequestrate and hypogeous were added. The best-known members are the highly regarded and commercially picked true morels of the genus Morchella, the thimble morels of the genus Verpa, and a genus of cup-shaped fungi Disciotis. The remaining four genera produce the sequestrate fruit bodies.

<i>Cookeina</i> Genus of fungi

Cookeina is a genus of cup fungi in the family Sarcoscyphaceae, members of which may be found in tropical and subtropical regions of the world. Species may be found on fallen branches of angiosperms, trunks, and sometimes on fruits. The Temuans of Peninsular Malaysia are reported to use certain species from this genus as food, and also as a bait for fishing, where it is rubbed against the hook.

<i>Chorioactis</i> Genus of fungi that contains the single species Chorioactis geaster

Chorioactis is a genus of fungi that contains the single species Chorioactis geaster. The mushroom is commonly known as the devil's cigar or the Texas star in the United States, while in Japan it is called kirinomitake (キリノミタケ). This extremely rare mushroom is notable for its unusual appearance and disjunct distribution; it is found only in select locales in Texas and Japan. The fruit body, which grows on the stumps or dead roots of cedar elms or dead oaks, somewhat resembles a dark brown or black cigar before it splits open radially into a starlike arrangement of four to seven leathery rays. The interior surface of the fruit body bears the spore-bearing tissue known as the hymenium, and is colored white to brown, depending on its age. The fruit body opening can be accompanied by a distinct hissing sound and the release of a smoky cloud of spores.

<i>Pseudoplectania</i> Genus of fungi

Pseudoplectania is a genus of fungi in the family Sarcosomataceae. The genus contains 12 species. Pseudoplectania ryvardenii was described in 2012, while Pseudoplectania carranzae was transferred to the genus in 2013.

<i>Sarcosoma</i> Genus of fungi

Sarcosoma is a genus of fungi in the family Sarcosomataceae. The name Sarcosoma is derived from ancient Greek and means “Fleshy body” σάρξ σῶμα. The genus is widespread in north temperate areas. The anamorph (asexual) form is the genus Verticicladium.

<i>Ruhlandiella</i> Genus of fungi

Ruhlandiella is a genus of fungi within the family Pezizaceae. Ruhlandiella species are exothecial hypogeous fungi, which are essentially truffles that lack the outer layer or peridium. Ruhlandiella species are widely distributed in Nothofagaceae forests in South America and near Eucalyptus or Melaleuca plants in Australia, North America, and Europe.

<i>Wynnea americana</i> Species of fungus

Wynnea americana, commonly known as moose antlers or rabbit ears, is a species of fungus in the family Sarcoscyphaceae. This uncommon inedible species is recognizable by its spoon-shaped or rabbit-ear shaped fruit bodies that may reach up to 13 cm (5.1 in) tall. It has dark brown and warty outer surfaces, while the fertile spore-bearing inner surface is orange to pinkish to reddish brown. The fruit bodies grow clustered together from large underground masses of compacted mycelia known as sclerotia. In eastern North America, where it is typically found growing in the soil underneath hardwood trees, it is found from New York to Michigan south to Mexico. The species has also been collected from Costa Rica, India, and Japan.

<i>Sarcoscypha occidentalis</i> Species of fungus

Sarcoscypha occidentalis, commonly known as the stalked scarlet cup or the western scarlet cup, is a species of fungus in the family Sarcoscyphaceae of the Pezizales order. Fruit bodies have small, bright red cups up to 2 cm (0.8 in) wide atop a slender whitish stem that is between 1 and 3 cm long. A saprobic species, it is found growing on hardwood twigs, particularly those that are partially buried in moist and shaded humus-rich soil. The fungus is distributed in the continental United States east of the Rocky Mountains, Central America, the Caribbean, and Asia. It is distinguished from the related species S. coccinea and S. austriaca by differences in geographical distribution, fruiting season, and fruit body structure. Phylogenetic analysis has shown that it is most closely related to other Sarcoscypha species that contain large oil droplets in their spores. The species Molliardiomyces occidentalis is an imperfect form of the fungus that lacks a sexually reproductive stage in its life cycle.

<i>Carbomyces emergens</i>

Carbomyces emergens is a desert truffle in the genus Carbomyces, a small genus common to the Chihuahuan desert in the southwestern United States and Mexico. C. emergens is regarded as the most common and widely distributed species in Carbomyces, also serving as the genus' type species. C. emergens belongs to the Carbomycetaceae family, in the order Pezizales, class Pezizomycetes, division Ascomycota.
