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).
Sordaria fimicola is a species of microscopic fungus. It is commonly found in the feces of herbivores. Sordaria fimicola is often used in introductory biology and mycology labs because it is easy to grow on nutrient agar in dish cultures. The genus Sordaria, closely related to Neurospora and Podospora, is a member of the large class Sordariomycetes, or flask-fungi. The natural habitat of the three species of Sordaria that have been the principal subjects in genetic studies is dung of herbivorous animals. The species S. fimicola is common and worldwide in distribution. The species of Sordaria are similar morphologically, producing black perithecia containing asci with eight dark ascospores in a linear arrangement. These species share a number of characteristics that are advantageous for genetic studies. They all have a short life cycle, usually 7–12 days, and are easily grown in culture. Most species are self-fertile and each strain is isogenic. All kinds of mutants are easily induced and readily obtainable with particular ascospore color mutants. These visual mutants aid in tetrad analysis, especially in analysis of intragenic recombination.
The order Sordariales is one of the most diverse taxonomic groups within the Sordariomycetes.
The Sordariaceae are a family of perithecial fungi within the Sordariales order.
Cercophora is a genus of fungi which was within the Lasiosphaeriaceae family. As of 2020, it was placed into the Neoschizotheciaceae family.
Polytolypa is a monotypic genus of fungus containing the single species Polytolypa hystricis. First classified in the Onygenaceae family, as of 2008 it is considered to be in the Ajellomycetaceae, although there is still uncertainty as to its phylogenetic relationships with other similar genera. This species is only known from a single specimen derived in the laboratory from a specimen of dung of the North American porcupine, Erethizon dorsatum, collected in Ontario, Canada. Polytolypa hystricis contains bioactive compounds that have antifungal activity.
Thielavia subthermophila is a ubiquitous, filamentous fungus that is a member of the phylum Ascomycota and order Sordariales. Known to be found on plants of arid environments, it is an endophyte with thermophilic properties, and possesses dense, pigmented mycelium. Thielavia subthermophila has rarely been identified as a human pathogen, with a small number of clinical cases including ocular and brain infections. For treatment, antifungal drugs such as amphotericin B have been used topically or intravenously, depending upon the condition.
Chaetomium elatum is a very common and widely distributed saprotrophic fungus of the Chaetomiaceae family of molds which has been found to grow on many different substances all over the world. It was first established by Gustav Kunze after he observed it growing on dead leaves. Its defining features that distinguish it from other Chaetomium species are its extremely coarse terminal hairs and the lemon-shaped morphology of its ascospores. It produces many metabolites with potential biotechnology uses including one with promise against the rice blast disease fungus, Magnaporthe grisea. It shows very little pathogenic ability causing confirmed disease in only a few plant species.
Collariella bostrychodes is a fungal decomposer of lignin and carbohydrate in the family Chaetomiaceae commonly found in soil and dung. The fungus is distinguished by a darkened collar-like ostiole around the ostiolar pore, giving the fungus its name. The fungus is highly variable in shape and form, giving raise to the belief that there are two subclades in the species. The ascospores range from lemon-shaped to nearly spherical with slightly pointed ends. It can grow to be pale green and later turn pale bluish grey or olivaceous with age. The fungus produces the toxic secondary metabolite, chaetochromin.
Botryotrichum piluliferum is a fungal species first identified in 1885 by Saccardo and Marchal. It was discovered to be the asexual state of a member of the ascomycete genus, Chaetomium. The name B. piluliferum now applies to the fungus in all its states. B. piluliferum has been found worldwide in a wide range of habitats such as animal dung and vegetation. The colonies of this fungus start off white and grow rapidly to a brown colour. The conidia are smooth and white. B. piluliferum grows optimally at a temperature of 25-30 °C and a pH of 5.5.
Arcopilus aureus is a plant and soil fungus in the genus Arcopilus. It was first identified by A. H. Chivers in 1912, who named it Chaetomium aureum. It was later transferred to the genus Arcopilus by Wang and colleagues. The fungus has recently been recognized to have industrial use for the production of the metabolites resveratrol. and sclerotiorin Additionally, A. aureus has high lead tolerance and clearance, suggesting a potential role in environmental biotechnology.
Microascus manginii is a filamentous fungal species in the genus Microascus. It produces both sexual (teleomorph) and asexual (anamorph) reproductive stages known as M. manginii and Scopulariopsis candida, respectively. Several synonyms appear in the literature because of taxonomic revisions and re-isolation of the species by different researchers. M. manginii is saprotrophic and commonly inhabits soil, indoor environments and decaying plant material. It is distinguishable from closely related species by its light colored and heart-shaped ascospores used for sexual reproduction. Scopulariopsis candida has been identified as the cause of some invasive infections, often in immunocompromised hosts, but is not considered a common human pathogen. There is concern about amphotericin B resistance in S. candida.
Myxotrichum chartarum is a psychrophilic and cellulolytic fungus first discovered in Germany by Gustav Kunze in 1823. Its classification has changed many times over its history to better reflect the information available at the time. Currently, M. chartarum is known to be an ascomycete surrounded by a gymnothecium composed of ornate spines and releases asexual ascospores. The presence of cellulolytic processes are common in fungi within the family Myxotrichaceae. M. chartarum is one of many Myxotrichum species known to degrade paper and paper products. Evidence of M. chartarum "red spot" mold formation, especially on old books, can be found globally. As a result, this fungal species and other cellulolytic molds are endangering old works of art and books. Currently, there is no evidence that suggests that species within the family Myxotrichaceae are pathogenic.
Zopfiella ebriosa is an unharmful fungus discovered covering the corks of wine bottles in 1991 in Tarragona, Spain. A member of the division Ascomycota, Zopfiella ebriosa is characterized by small and asymmetrical asci, presence of ostioles, and possession of germ slits.
Podospora appendiculata is a coprophilous fungus that is most commonly found in the dung of lagomorphs, such as hares and rabbits, in temperate to warm climates. A member of the division Ascomycota, P. appendiculata is characterized by ovoid, hair-studded perithecia which can bear a distinctive violaceous colouring and peridia which are coriaceous, or leathery, in texture. Podospora appendiculata has been shown to produce three compounds with antimicrobial properties.
Triangularia setosa is a member of the Ascomycota, and of the genus Triangularia. This genus is notable for its widespread appearance on the excrement of herbivores, and is therefore seen as a coprophilous fungus. The fungus itself is characteristically dark in colour and produces sac-like perithecium with a covering of hair. Its dispersion involves the ingestion, passage, and projectile ejection of spores. It has preference for colonizing the dung of lagomorphs, such as hares and rabbits.
Pseudothielavia terricola is a fungal species of the phylum Ascomycota, family Chaetomiaceae, and genus Pseudothielavia. Pseudothielavia terricola is widely distributed, especially in the tropical region of the world – with documented appearances in Africa, Southern Europe, and Asia. The species is mainly found in soil, but can also be found on other materials such as animal dung. The species was first assigned to the genus Coniothyrium in 1927, but was soon re-assigned to the genus Thielavia which endured for almost 90 years. Through intensive phylogenetic research and reassessment, the species was designated to a new genus, Pseudothielavia; the etymology of Pseudothielavia means similar to the genus Thielavia – the high resemblance was what contributed to the species assignment to the genus Thielavia nine decades ago. The fungus is mesophilic, grows abundantly in a pH level between 3.9–6, and is able to utilize multiple carbohydrates to support its growth. Mature Pseudothielavia terricola colonies in culture is dark brown in colour and spread out. Pseudothielavia terricola synthesizes a variety of compounds, two of which are thielavin A & B. These compounds were determined to be strong inhibitors of prostaglandin synthesis.
Anopodium ampullaceum is a species of fungus first discovered by Nils Lundqvist in Sweden, in the year 1964. A. ampullaceum became one of the first few fungi along with Anopodium epile and Podospora dagonerii, to be placed in the new genus Anopodium due to their unique spores that did not suit the description of the spores of the Podospora genus, which P. dagonerii had previously belonged to. The genus Anopodium deviates from other members of the Sordariomycetes class by two spore characteristics; firstly the pedicels of its spore in the apical position, and secondly due to its immature spores having spherical bodies with cylindrical apical regions. As of 1998 all three of these species are now considered to be one species, using the name A. ampullaceum.
Zwackhiomacromyces is a genus of lichenicolous (lichen-dwelling) fungi in the family Xanthopyreniaceae. It has two species. The genus is distinguished by its black, pear-shaped fruiting bodies with large, nipple-shaped ostioles that have a granular surface, and a dark, multi-layered wall made up of hyphal cells forming a pseudoparenchymatous structure. The genus is closely related to the similarly named genus Zwackhiomyces.
The Pyrenotrichaceae are a small family of fungi in the order Chaetothyriales. It contains two genera, and a total of six species. The genus Pyrenothrix has two species of bark- or leaf-dwelling lichens, while Neophaeococcomyces has four species of saprobic fungi.
