A sclerotium, is a compact mass of hardened fungal mycelium containing food reserves. One role of sclerotia is to survive environmental extremes. In some higher fungi such as ergot, sclerotia become detached and remain dormant until favorable growth conditions return. Sclerotia initially were mistaken for individual organisms and described as separate species until Louis René Tulasne proved in 1853 that sclerotia are only a stage in the life cycle of some fungi. Further investigation showed that this stage appears in many fungi belonging to many diverse groups. Sclerotia are important in the understanding of the life cycle and reproduction of fungi, as a food source, as medicine, and in agricultural blight management.
Paxillus is a genus of mushrooms of which most are known to be poisonous or inedible. Species include Paxillus involutus and Paxillus vernalis. Two former species—Tapinella panuoides and Tapinella atrotomentosa—have now been transferred to the related genus Tapinella in the family Tapinellaceae
Peter Henry Rolfs (1865–1944) was a prominent Florida agronomist in the early 20th century. He directed the Florida Agriculture Experiment Station from 1905 to 1920, and from 1915 to 1920 served as the Dean of the College of Agriculture at the University of Florida. Rolfs then moved to Brazil to found the Escola Superior de Agricultura e Veterinária in Viçosa, Minas Gerais, renamed to Universidade Federal de Viçosa.
Agroathelia delphinii is a plant pathogen infecting many tropical and warm temperate plants including mangoes.
Anomoporia is a genus of fungi in the family Amylocorticiaceae. The genus was circumscribed by Czech mycologist Zdeněk Pouzar in 1966.
Ceraceomyces is a genus of fungi in the family Amylocorticiaceae. The genus has a widespread distribution and contains 16 species.
Anomoloma is a genus of crust fungi in the family Amylocorticiaceae. It was circumscribed by mycologists Tuomo Niemelä and Karl-Henrik Larsson in 2007. The generic name is derived from the Greek anomos, meaning "lawless", which in this context alludes to the irregular rhizomorphic outline, and loma, meaning margin or edge.
Jaapia is a genus in the monotypic family Jaapiaceae and order Jaapiales. The genus was first described by Italian mycologist Giacomo Bresadola in 1911, and contains two widely distributed species, J. argillacea and J. ochroleuca. The order was described in 2010.
Athelia is a genus of corticioid fungi in the family Atheliaceae. Some species are facultative parasites of plants and of lichens. The widespread genus contains 28 species. However, Athelia rolfsii was found to belong in the Amylocorticiales in a molecular phylogenetics study and renamed Agroathelia rolfsii.
The corticioid fungi are a group of fungi in the Basidiomycota typically having effused, smooth basidiocarps that are formed on the undersides of dead tree trunks or branches. They are sometimes colloquially called crust fungi or patch fungi. Originally such fungi were referred to the genus Corticium and subsequently to the family Corticiaceae, but it is now known that all corticioid species are not necessarily closely related. The fact that they look similar is an example of convergent evolution. Since they are often studied as a group, it is convenient to retain the informal (non-taxonomic) name of "corticioid fungi" and this term is frequently used in research papers and other texts.
Podoserpula is a genus of fungi in the family Amylocorticiaceae. The genus contains two species: the type, P. pusio, commonly known as the pagoda fungus, and the "Barbie pagoda", P. miranda, officially published in 2013. Podoserpula species produce fruit bodies consisting of up to a dozen caps arranged in overlapping shelves, attached to a central axis. Its unique shape is not known to exist in any other fungi. Four varieties of P. pusio are known, which differ in their sizes, spore morphology, and distribution. The genus is known to occur in Australia and New Zealand, Venezuela, Madagascar, and New Caledonia.
Irpicodon is a genus of fungi in the family Amylocorticiaceae. The genus is monotypic, containing the single species Irpicodon pendulus, found in Europe.
Amyloxenasma is a genus of corticioid fungi in the family Amylocorticiaceae. The widely distributed genus contains six species.
Amylocorticiellum is a genus of fungi in the family Amylocorticiaceae. The genus has a widespread distribution and contains four species.
Amylocorticiales is an order of fungi in the class Agaricomycetes. The order was circumscribed in 2010 to contain mostly resupinate (crust-like) forms that have been referred to genera Anomoporia, Amyloathelia, Amylocorticiellum, Amylocorticium, Amyloxenasma, Anomoloma, Athelopsis, Ceraceomyces, Hypochniciellum, Leptosporomyces and Serpulomyces and the anomalous species, Athelia rolfsii, now classified in its own genus, Agroathelia.
Athelopsis is a genus of corticioid fungi in the family Amylocorticiaceae. The widespread genus, estimated to contain 10 species, is polyphyletic as currently circumscribed.
Hypochniciellum is a genus of corticioid fungi in the family Amylocorticiaceae. Species in the genus have white to cream, resupinate fruit bodies. The hyphae have clamp connections. The spores are roughly elliptical, yellowish, and smooth.
Leptosporomyces is a genus of resupinate (crust-like) fungi in the family Amylocorticiaceae. The genus is widespread in the Northern Hemisphere and contains 11 species.
Agroathelia is a fungal genus currently consisting of one widespread and two other species. Agroathelia rolfsii, the type species, causes serious diseases of cultivated crops such as tomatoes, potatoes, peanuts, bell peppers, and sweet potatoes among many other hosts. It is better known under the names Sclerotium rolfsii or Athelia rolfsii.
Agroathelia rolfsii is a corticioid fungus in the order Amylocorticiales. It is a facultative plant pathogen and is the causal agent of "southern blight" disease in crops.
