Colletotrichum acutatum is a plant pathogen and endophyte. It is the organism that causes the most destructive fungal disease, anthracnose, of lupin species worldwide. It also causes the disease postbloom fruit drop on many varieties of citrus, especially Valencia and navel oranges in Florida.
Glomerella cingulata is a fungal plant pathogen, being the name of the sexual stage (teleomorph) while the more commonly referred to asexual stage (anamorph) is called Colletotrichum gloeosporioides. For most of this article the pathogen will be referred to as C. gloeosporioides. This pathogen is a significant problem worldwide, causing anthracnose and fruit rotting diseases on hundreds of economically important hosts.
Colletotrichum is a genus of fungi that are symbionts to plants as endophytes or phytopathogens. Many of the species in this genus are plant pathogens, but some species may have a mutualistic relationship with hosts.
Cladosporium dominicanum is a fungus found in hypersaline environments. It has globoid conidia. It has also been found in plant material.
Cladosporium psychrotolerans is a fungus found in hypersaline environments. It grows well at 4 °C but not at 30 °C, and has ornamented, globoid conidia with long digitate projections.
Cladosporium velox is a fungus found in hypersaline environments. It has globoid conidia. It has also been found in plant material.
Cladosporium spinulosum is a fungus found in hypersaline environments. It has globoid, ornamented conidia with long digitate projections.
Cladosporium halotolerans is a fungus found in hypersaline environments. It has globoid conidia. It has also been isolated from bathrooms and in a dolphin.
Cladosporium fusiforme is a fungus found in hypersaline environments. It has ovoid to ellipsoid conidia. It has also been found in animal feed.
Cladosporium salinae is a fungus found in hypersaline environments. It has ovoid to ellipsoid conidia. It has also been found in animal feed.
Ross Ewen Beever was a New Zealand geneticist and mycologist.
Glomerellales is an order of ascomycetous fungi within the subclass Hypocreomycetidae (Sordariomycetes). The order includes saprobes, endophytes and pathogens on plants, animals and other fungi with representatives found all over the world in varying habitats.
Aspergillus keveii is a species of fungus in the genus Aspergillus which has been isolated from soil from Las Palmas in Spain. It is from the Usti section. It has been reported to produce drimans, ophiobolins G and H, and nidulol.
Glomerellaceae is a monotypic family of fungi in the class Sordariomycetes that contains only one genus, Colletotrichum.
Colletotrichum fioriniae is a fungal plant pathogen and endophyte of fruits and foliage of many broadleaved plants worldwide. It causes diseases on agriculturally important crops, including anthracnose of strawberry, ripe rot of grapes, bitter rot of apple, anthracnose of peach, and anthracnose of blueberry. Its ecological role in the natural environment is less well understood, other than it is a common leaf endophyte of many temperate trees and shrubs and in some cases may function as an entomopathogen.
Bitter rot of apple is a fungal disease of apple fruit that is caused by several species in the Colletotrichum acutatum and Colletotrichum gloeosporioides species complexes. It is identified by sunken circular lesions with conical intrusions into the apple flesh that appear V-shaped when the apple is cut in half through the center of the lesion. It is one of the most devastating diseases of apple fruit in regions with warm wet weather.
