Fungi named in 2006

The Ascomycota are a phylum in the kingdom Fungi that, together with the Basidiomycota, form the subkingdom Dikarya. Members of Ascomycota are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the ascus (from Ancient Greek ἀσκός (askós) 'sac, wineskin'), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of Ascomycota are asexual and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles,

Pucciniomycetes (formerly known as Urediniomycetidae) is a diverse class of fungi in the subphylum Pucciniomycotina of phylum Basidiomycota. The class contains 5 orders, 21 families, 190 genera, and approximately 8,016 species. It has been estimated that this class contains about one third of all teleomorphic basidiomycetes. Pucciniomycetes contains many economically important plant pathogenic fungal rusts; the order Pucciniales (formerly Uredinales) is the largest clade in this class, representing approximately 7,000 species. Pucciniomycetes are cosmopolitan and can be found in both

Pucciniomycotina is a subdivision of fungus within the division Basidiomycota. The group was known as Urediniomycetes until 2006, when it was elevated from a class to a subdivision and named after the largest order in the group, Pucciniales. The subdivision contains 10 classes, 21 orders, and 38 families. Over 8400 species of Pucciniomycotina have been described; thus, the subdivision contains more than 8% of all described fungi. Pucciniomycotina appears to be sister to Agaricomycotina, based on maximum-likelihood analysis of six genes.

The Microbotryomycetes are a class of fungi in the subdivision Pucciniomycotina of the Basidiomycota. The class currently contains eight orders, plus three additional, unassigned families (Chrysozymaceae, Colacogloeaceae, and Mycogloiocolacaceae), plus seven additional, unassigned genera (Oberwinklerozyma, Pseudohyphozyma, Reniforma, Spencerozyma, Trigonosporomyces, Vonarxula, and Yunzhangia). Many species are known only from their yeast states. Species with hyphal states typically produce auricularioid (laterally septate) basidia and are often parasitic on other fungi or plants. Several

The Exobasidiomycetes are a class of fungi sometimes associated with the abnormal outgrowths of plant tissues known as galls. The class includes Exobasidium camelliae Shirai, the camellia leaf gall and Exobasidium vaccinii Erikss, the leaf and flower gall. There are seven orders in the Exobasidiomycetes, including the Ceraceosorales, Doassansiales, Entylomatales, Exobasidiales, Georgefischeriales, Microstromatales and the Tilletiales. Four of the seven orders include smut fungi. The family Ceraceosoraceae was formally validated in 2009 for the order Ceraceosorales. Malasseziales was once

The Cystobasidiomycetes are a class of fungi in the subdivision Pucciniomycotina of the Basidiomycota. Most species are known from their yeast states; hyphal states, when present, produce auricularioid (laterally septate) basidia and are frequently (possibly always) parasites of other fungi. The class contains five orders (Buckleyzymales, Cystobasidiales, Erythrobasidiales, Naohideales, and Sakaguchiales) as well as two families (Microsporomycetaceae and Symmetrosporaceae) and one genus (Queiroziella) of uncertain disposition. An additional order, Cyphobasidiales, has been proposed to

The Agaricostilbomycetes are a class of fungi in the subdivision Pucciniomycotina of the Basidiomycota. The class consists of a single order, six families, and 15 genera. Its type genus, Agaricostilbum was originally placed in Ascomycota, and later, Agaricomycotina, before being placed in Pucinniomycotina. Most species are known only from their yeast states. Where known, basidiocarps (fruitbodies) are typically small and stilboid (pin-shaped). They tend to by mycoparasitic (parasitise other fungi) or saprobic. Their spindle pole bodies (fungal organelles that are functionally equivalent to

Entorrhizomycetes is the sole class in the phylum Entorrhizomycota, within the Fungi subkingdom Dikarya along with Basidiomycota and Ascomycota. It contains three genera and is a small group of teliosporic root parasites that form galls on plants in the Juncaceae (rush) and Cyperaceae (sedge) families. Prior to 2015 this phylum was placed under the subdivision Ustilaginomycotina. A 2015 study did a "comprehensive five-gene analyses" of Entorrhiza and concluded that the former class Entorrhizomycetes is possibly either a close sister group to the rest of Dikarya or Basidiomycota.

The Atractiellomycetes are class of fungi in the Pucciniomycotina subdivision of the Basidiomycota. The class consists of a single order, the Atractiellales, which contains 3 families, 10 genera, and 58 species.

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.

Ochrolechia is the sole genus in the fungal family Ochrolechiaceae. It comprises about 40 species of crustose lichens. These lichens typically form uneven, often thick, crust-like growths on various surfaces and are characterised by their white to pale grey thalli, which may have a greenish tint. The genus has a long evolutionary history, with fossils dating back to the Paleogene period, about 34 million years ago. Ochrolechia species have disc-like apothecia (fruiting bodies), which are usually yellowish or brownish-pink and often covered with a fine white powdery coating. The genus is

Neonectria ditissima (syn. Neonectria galligena) is a fungal plant pathogen. It causes cankers that can kill branches of trees by choking them off. Apple and beech trees are two susceptible species.

Moniliophthora perniciosa (previously Crinipellis perniciosa) is a fungus that causes "witches' broom disease" (WBD) of the cocoa tree T. cacao. This pathogen is currently limited to South America, Panama and the Caribbean, and is perhaps one of the best-known cocoa diseases, thought to have co-evolved with cocoa in its centre of origin (first recorded in the Brazilian Amazon in 1785). This fungus is hemibiotroph, with two characteristic phases: biotrophic (expanding and infecting, on living tissue) and saprotrophic (producing basidiospores, on necrotic tissue). The biotrophic stage, and what

Cryphonectriaceae is a family of fungi in the order Diaporthales.

Peroneutypa scoparia is a carbonaceous pyrenomycete small in size, rarely reaching a centimeter in height. It grows on dead wood, and grows in thin, upright projections. With the help of magnification, a grooving pattern on the tips similar to a philips-head screwdriver can be seen.

The Helicobasidiales are an order of fungi in the subdivision Pucciniomycotina. The order is currently monotypic, containing the single family Helicobasidiaceae which itself is monotypic, containing the single genus Helicobasidium. The anamorphic genus Tuberculina is a synonym of Helicobasidium, but species are not currently integrated in the latter genus.

The Classiculomycetes are a class of fungi in the Pucciniomycotina subdivision of the Basidiomycota. The class contains a single order, the Classiculales, which in turn contains the single family Classiculaceae. The family contains two monotypic genera. They belong to a morpholigical group called "aquatic hyphomycetes" which are fungi that grow on submerged decaying plant matter, but they are also found as mycoparasites and endophytes. This is only an informal descriptive group which is divided phylogenetically between asco types (the great majority) and basidio types (a small percentage of

Coprinellus bipellis is a species of mushroom in the family Psathyrellaceae. It was first described as Coprinus bipellis by Henri Romagnesi in 1976, and later transferred to the genus Coprinellus in 2006.

Xanthoparmelia alligatensis is a species of saxicolous (rock-dwelling), foliose lichen in the family Parmeliaceae, described by John Elix in 2006. The species is native to South Australia, specifically found in the Mount Remarkable National Park.

Septoria malagutii is a fungal plant pathogen infecting potatoes. The casual fungal pathogen is a deuteromycete and therefore has no true sexual stage. As a result, Septoria produces pycnidia, an asexual flask shaped fruiting body, on the leaves of potato and other tuber-bearing spp. causing small black to brown necrotic lesions ranging in size from 1-5mm. The necrotic lesions can fuse together forming large necrotic areas susceptible to leaf drop, early senescence, dieback, and dwarfing. Septoria malagutii has been found only in the Andean countries of Bolivia, Ecuador, Peru, and Venezuela

Russula parvovirescens is a basidiomycete mushroom of the genus Russula. Found in the eastern United States, it was described as new to science in 2006.

Perenniporia meridionalis is a poroid crust fungus in the family Polyporaceae. It was described as a new species by Cony Decock and Joost Stalpers in 2006. The holotype specimen was collected in the Province of Nuoro in Italy, where it was found growing on dead wood of Quercus ilex. Distinguishing characteristics of this fungus include its relatively large pores (typically numbering 3 or 4 per millimetre), the hyaline vegetative hyphae that are yellowish to slightly dextrinoid in Melzer's reagent, and large spores measuring 6.0–7.7 by 4.5–6.2 μm. P. meridionalis occurs in central and southern
