Acanthostigma is a genus in the Tubeufiaceae family of fungi. [1] Three new species were reported in 2010, growing from decomposing wood in Great Smoky Mountains National Park in the United States. [2]

Contents

The three new bitunicate ascomycetes belonging to the genus Acanthostigma are described from terrestrial decomposing wood collected from Great Smoky Mountains National Park, USA. Phylogenetic analyses of the nuclear ribosomal 28S large subunit and internal transcribed spacer region placed all three species in the Tubeufiaceae and confirmed morphological analyses that these are distinct species.
Expanded phylogenetic analyses of 28S large subunit including taxa throughout the Dothideomycetes confirmed the placement of Acanthostigma in the Tubeufiaceae.

Acanthostigma filiforme differs from other Acanthostigma species in having longer ascospores with more septa. Acanthostigma multiseptatum can be distinguished in having longer asci and longer ascospores with more septa.

Acanthostigma septoconstrictum differs in having longer setae and asci and broader, asymmetrical ascospores that are constricted at their septa. A dichotomous key to Acanthostigma species is provided. [3]

The Pezizales are an order of the subphylum Pezizomycotina within the phylum Ascomycota. The order contains 16 families, 199 genera, and 1683 species. 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.

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

The Hysteriaceae are a taxonomic family of fungi and the only extant family of the order Hysteriales. Members of the Hysteriaceae are defined by the possession of a sexual structure called the hysterothecium, an elongated structure that opens by a longitudinal slit and releases sexually produced spores. The family is widely distributed, with many species found in temperate regions, and most are saprobic on wood and bark, although a few are parasitic on plants.

<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.

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.

The Arthoniales is the second largest order of mainly crustose lichens, but fruticose lichens are present as well. The order contains around 1500 species, while the largest order with lichenized fungi, the Lecanorales, contains more than 14000 species.

<i>Morchella elata</i> Species of fungus

Morchella elata is a species of fungus in the family Morchellaceae. It is one of many related species commonly known as black morels, and until 2012 the name M. elata was broadly applied to black morels throughout the globe. Like most members of the genus, M. elata is a popular edible fungus and is sought by many mushroom hunters.

<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>Lophiostoma</i> Genus of fungi

Lophiostoma is a genus of ascomycetous fungi in the family Lophiostomataceae.

The Aliquandostipitaceae are a family of fungi in the Ascomycota, class Dothideomycetes. The family was described by Patrik Inderbitzin in 2001, and the order Jahnulales was created in 2002 to accommodate the family. The distinguishing characteristic for members of the family are the unusually wide hyphae that support the spore-bearing structures, and the presence of ascomata both with and without stalks. The genus Aliquandostipe has a pantropical distribution, having been found in Central America and southeast Asia; Jahnula has a wider distribution. Species in the family are saprobic, and are typically found growing on rotting wood.

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

The Magnaporthaceae are a family of fungi in the order Magnaporthales. It was circumscribed by Paul F. Cannon in 1994 for a group of grass-associated fungi centered on Magnaporthe (Nakataea). Magnaporthaceae have a harpophora-like asexual morphology and are often associated with roots of grasses or cereals.

<i>Glutinoglossum glutinosum</i> Species of fungus

Glutinoglossum glutinosum, commonly known as the viscid black earth tongue or the glutinous earthtongue, is a species of fungus in the family Geoglossaceae. Widely distributed in the Northern Hemisphere, it has been found in northern Africa, Asia, Europe, and North America. Although previously thought to exist in Australasia, collections made from these locations have since been referred to new species. G. glutinosum is a saprophytic species that grows on soil in moss or in grassy areas. The smooth, nearly black, club-shaped fruitbodies grow to heights ranging from 1.5 to 5 cm. The head is up to 0.7 cm (0.3 in) long, and the stipes are sticky. Several other black earth tongue species are quite similar in external appearance, and many can be reliably distinguished only by examining differences in microscopic characteristics, such as spores, asci, and paraphyses. First described in 1796 as a species of Geoglossum, the fungus has gone through several changes of genera in its taxonomic history. It was placed in its current genus, Glutinoglossum, in 2013.

<i>Morchella anatolica</i> Species of fungus

Morchella anatolica is a rare species of ascomycete fungus in the family Morchellaceae. It was described as new to science in 2010 from southwest Anatolia, Turkey, where it grows on moss-covered stream beds in pine forests. An ancient climatic relict, M. anatolica is restricted to the Mediterranean basin and has also been documented in Spain, Cyprus and Greece, where it is sometimes encountered with trees of the Oleaceae family. Together with its sister-species Morchella rufobrunnea, they are the earliest diverging lineages in genus Morchella, forming a distinct clade that is basal in global morel phylogenies. Because of its phylogenetic position, M. anatolica has been crucial in inferring the historical biogeography of the genus, which is estimated to have emerged somewhere in the Mediterranean region in the late Jurassic.

Acanthostigma septoconstrictum is a species of fungus in the Tubeufiaceae family of fungi. It was isolated from decomposing wood in the Great Smoky Mountains National Park. A. septoconstrictum differs from its cogenerate species by having longer setae and asci and broader, asymmetrical ascospores which are constricted at their septa.

Acanthostigma multiseptatum is a species of fungus in the Tubeufiaceae family of fungi. It was isolated from decomposing wood in the Great Smoky Mountains National Park. A. multiseptatum differs from its cogenerate species by having longer asci and longer ascospores with more septa.

Acanthostigma filiforme is a species of fungus in the Tubeufiaceae family of fungi. It was isolated from decomposing wood in the Great Smoky Mountains National Park. A. filiforme differs from its cogenerate species by having longer ascospores with more septa.

<i>Morchella arbutiphila</i> Species of fungus

Morchella arbutiphila is a species of fungus in the family Morchellaceae (Ascomycota), described from the island of Cyprus in 2016. The species is notable for its elongated stipe, which is often longer than the cap's length, its ascospores which are larger than most other species of Morchella, and its highly specific ecological preferences. It is known only from igneous substrates of the Troodos mountains in Cyprus and from a single collection in the Aegean region of Turkey.

<i>Morchella disparilis</i> Species of fungus

Morchella disparilis is an Ascomycete fungus in the family Morchellaceae. Described as new to science in 2016, M. disparilis appears to be confined to the Mediterranean basin and is so far known from Cyprus, Greece and Spain. Its most striking feature is the exceptionally deep sinus, intermediate in depth between half-free morels of the Morchella semilibera clade and typical Distantes species.

Capronia mansonii is a mesophilic black yeast that is a part of the Herpotrichiellaceae. The species is uncommon in nature but is saprotrophic in nature and been discovered on decaying plant matter, particularly wood. This fungus is naturally found in the Netherlands and has successfully been cultured in lab. It is a teleomorph of the ascomycota division and possesses brown spores.

Astrothelium chulumanense is a little-known species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. Found in the Yungas montane forest of Bolivia, it was formally described as a new species in 2023. It is characterized by pseudostromata not differing in colour from the thallus, perithecia immersed for the most part in the thallus with the upper part elevated above and covered with orange pigment, apical and fused ostioles, the absence of lichexanthone, a clear hamathecium, eight-spored asci, and large, muriform ascospores with a thickened median septum.
