Cattleya
''Cattleya'' () is a genus of orchids from Costa Rica south to Argentina. The genus is abbreviated C in trade journals. Description Epiphytic or terrestrial orchids with cylindrical rhizome from which the fleshy noodle-like roots grow. Pseudobulbs can be conical, spindle-shaped or cylindrical; with upright growth; one or two leaves growing from the top of them. The leaves can be oblong, lanceolate or elliptical, somewhat fleshy, with smooth margin. The inflorescence is a terminal raceme with few or several flowers. Flowers have sepals and petals free from each other; the lip or labellum (lowermost petal), usually has a different coloration and shape from the rest of the flower and covers in part the flower column forming a tube. There are four polliniums (bag-like organs that contain pollen). The fruit is a capsule with many small seeds.Schweinfurth, C., "Orchidaceae, Orchids of Peru", ''Fieldiana, Botany'' 30(3): 535 Taxonomy The genus was named in 1824 by John Lindley af ...

It causes leaf spots, starting with small yellowish lesions on the plant's leaves and darkening to brown or black. If the infection develops further, the leaves and fruit fall from the orchid and spread the infection.

Pseudocercospora
''Pseudocercospora'' is a genus of ascomycete fungi. An anamorphic version of the genus ''Mycosphaerella'', ''Pseudocercospora'' species are plant pathogens, including the causal agent of the so-called South American leaf blight of the rubber tree. The widely distributed genus has been estimated to contain over 1100 species, concentrated predominantly in tropical The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to ... regions. ''Pseudocercospora'' was circumscribed by Italian-Argentinian botanist Carlos Luigi Spegazzini in 1910.

Lasiodiplodia Theobromae
''Lasiodiplodia theobromae'' is a plant pathogen with a very wide host range. It causes rotting and dieback in most species it infects. It is a common post harvest fungus disease of citrus known as stem-end rot. It is a cause of bot canker of grapevine.Identification and Pathogenicity of Lasiodiplodia theobromae and Diplodia seriata, the Causal Agents of Bot Canker Disease of Grapevines in Mexico. J. R. Úrbez-Torres, G. M. Leavitt, J. C. Guerrero, J. Guevara and W. D. Gubler, Plant Disease, April 2008, Volume 92, Number 4, pages 519-529, It also infects '' Biancaea sappan'', a species of flowering tree also known as Sappanwood. On rare occasions it has been found to cause fungal keratitis, lesions on nail and subcutaneous tissue. It has been implicated in the widespread mortality of baobab (''Adansonia digitata'') trees in Southern Africa. A preliminary study found the deaths to have a complex set of causes requiring detailed research. Host and symptoms ''L. theobromae'' ca ...
