Septoria are ascomycete pycnidia-producing fungi that cause numerous leaf spot diseases on field crops, forages and many vegetables including tomatoes which are known to contract Septoria musiva from nearby cottonwood trees, and is responsible for yield losses. The genus is widespread, and estimated to contain 1072 species. Pycnidia produce needle-like pycnidiospores.
Coniothyrium glycines is a fungal plant pathogen infecting soybean.
Stagonospora is a genus of fungi clustering in the Phaeosphaeriaceae (Quaedvlieg). Several of the species in this genus are plant pathogens.
The Pleosporales is the largest order in the fungal class Dothideomycetes. By a 2008 estimate, it contained 23 families, 332 genera and more than 4700 species. The majority of species are saprobes on decaying plant material in fresh water, marine, or terrestrial environments, but several species are also associated with living plants as parasites, epiphytes or endophytes. The best studied species cause plant diseases on important agricultural crops e.g. Cochliobolus heterostrophus, causing southern corn leaf blight on maize, Phaeosphaeria nodorum causing glume blotch on wheat and Leptosphaeria maculans causing a stem canker on cabbage crops (Brassica). Some species of Pleosporales occur on animal dung, and a small number occur as lichens and rock-inhabiting fungi.
Phoma is a genus of common coelomycetous soil fungi. It contains many plant pathogenic species.
The Leptosphaeriaceae are a family of fungi in the order Pleosporales. The family was circumscribed by mycologist Margaret E. Barr in 1987. According to the Dictionary of the Fungi, the family contained 8 genera and 302 species. The family has a widespread distribution, but is especially prevalent in temperate regions. Species are either saprobic or grow as nectrotrophs on the stems or leaves of plants.
Calophoma clematidina is a fungal plant pathogen and the most common cause of the disease clematis wilt affecting large-flowered varieties of Clematis. Symptoms of infection include leaf spotting, wilting of leaves, stems or the whole plant and internal blackening of the stem, often at soil level. Infected plants growing in containers may also develop root rot.
Stagonosporopsis is a genus of ascomycote fungi, containing several pathogens to plants.
Coniothyrium is a genus of fungi in the family Coniothyriaceae. The genus was circumscribed by Czech mycologist August Carl Joseph Corda in 1840. It was formerly placed in the Phaeosphaeriaceae family until 1983 when the family was established.
The Didymellaceae are a family of fungi in the order Pleosporales. They have a world-wide distribution.
Peyronellaea is a genus of fungi in the family Didymellaceae. It contains a number of plant pathogens.
Peyronellaea curtisii is a fungal plant pathogen first described by Miles Joseph Berkeley and received its current name in 2010. Formerly it was Stagonosporacurtisii. It is a cause of leaf blotch, and its substrates include Narcissus, Galanthus and Hippeastrum.
Phoma wilt is a disease of the common hop plant caused by several species of fungal plant pathogens in the genus Phoma. These include Phoma herbarum and Phoma exigua, and possibly other as yet unidentified species. Phoma infection may cause decreased yields, but Phoma wilt is not considered to be a very common or destructive disease of the hop plant.
Aposphaeria is a genus of fungi in the family Melanommataceae. The genus was circumscribed in 1880 by Pier Andrea Saccardo, with Aposphaeria pulviscula selected as the type species.
Boeremia exigua is the type species of the fungus genus, Boeremia, in the Didymellaceae family. It was first described as Phoma exigua by John Baptiste Henri Joseph Desmazières in 1849, and transferred to the genus, Boeremia, by M.M. Aveskamp, J. de Gruyter, J.H.C. Woudenberg, G.J.M. Verkley and P.W. Crous in 2010.
Epicoccum is a genus of fungi belonging to the family Didymellaceae.
The Lentitheciaceae are a family of fungi in the order of Pleosporales. They are found world-wide with the greatest contributions found in Europe and Australia.
Coniothyriaceae is a family of ascomycetous marine based fungi within the order of Pleosporales in the subclass Pleosporomycetidae and within the class Dothideomycetes. They are pathogenic or they can be saprobic on dead branches. They are generally a anamorphic species.
