Colletotrichum Paxtonii
''Colletotrichum'' (sexual stage: ''Glomerella'') is a genus of fungus, fungi that are symbionts to plants as endophytes (living within the plant) or phytopathogens. Many of the species in this genus are plant pathogens, but some species may have a mutualism (biology), mutualistic relationship with host (biology), hosts. History The history of the ''Colletotrichum'' genus is a case study on the tension between the lumpers and splitters. While the genus ''Colletotrichum'' was first proposed in 1831, the exact definition of ''Colletotrichum'' and the species that belong in this genus has been in flux ever since. The biggest recent shift has been from a definition (of both the genus and the species within it) based on Morphology (biology), morphology to a definition based on a combination of morphology and molecular phylogenetics. The use of molecular phylogenetics has led to a huge increase in the number of recognized species in this genus, and the species are now organized into s ...

Colletotrichum Lindemuthianum
''Colletotrichum lindemuthianum'' is a fungus which causes anthracnose, or black spot disease, of the common bean plant (''Phaseolus vulgaris''). It is considered a hemibiotrophic pathogen because it spends part of its infection cycle as a biotroph, living off of the host but not harming it, and the other part as a necrotroph, killing and obtaining nutrients from the host tissues. History The anthracnose of common bean was first identified in 1875 in the fruit and vegetable garden of the Agricultural Institute of Popplesdorf, Germany by Lindemuth.Leach, Julian Gilbert. 1922.The parasitism of colletotrichum lindemuthianum. University of Minnesota. Retrieved 30 March 2014 By 1878, Saccardo and Magnus had made many observations on the cause of the anthracnose disease, recording their results in ''Michelia'' I:129.Stoneman, Bertha. 1898. A comparative study of the development of some anthracnoses. Botanical Gazette 26 (2) (August, 1898). They concluded that it was caused by a fungus, ...
