(2012) were able to recognize 18 species within the <em>C. boninense<\/em> complex including <em>C. cymbidiicola<\/em> based on DNA sequence data and morphology.\u00a0 <em>Colletotrichum cymbidiicola<\/em> is associated with orchids and is specific at plant genus level.<\/p>\n<p style=\"padding-left: 30px;\"><em>Hosts<\/em>: <em>Cymbidium<\/em> spp. (orchids) (Damm <em>et al.,<\/em> 2012).<\/p>\n<p style=\"padding-left: 30px;\"><em>Symptoms<\/em>:\u00a0 Anthracnose symptoms are expressed as dark spots or lesions in infected orchid leaves, petioles and blossoms.\u00a0 Initial symptoms include brown discolorations which are irregularly shaped sunken lesions that turn to dark brown with concentric brownish black fruiting bodies (acervuli).\u00a0 Leaf wilting may occur often resulting in dieback and reduction in plant quality.\u00a0 As in orchids infected with <em>Colletotrichum gloeosporioides<\/em>, symptoms may be most common on orchid leaves when stressed plants are damaged by cold and hot temperatures, sun, wind, chemicals and mechanical damage.<\/p>\n<p style=\"padding-left: 30px;\"><em>Damage Potential<\/em>:\u00a0 Anthracnose disease caused by <em>Colletotrichum cymbidiicola <\/em>can result in reduced plant quality and growth.\u00a0 Estimates of yield\/crop loss due to this pathogen have not been reported although severe outbreaks of orchid anthracnose have been reported in India (Chowdappa, <em>et al., <\/em>2014).\u00a0 Nursery production of potted host plants or in greenhouses are particularly at risk as nursery conditions are often conducive to infection by <em>Colletotrichum<\/em> species.\u00a0 In cultivated fields, disease development may be sporadic as it is affected by levels of pathogen inoculum and environmental conditions.<\/p>\n<p style=\"padding-left: 30px;\"><em>Disease Cycle<\/em>:\u00a0 It is likely that <em>Colletotrichum cymbidiicola<\/em> has a similar life cycle to that of other <em>Colletotrichum<\/em> species and survives between crops during winter as mycelium on plant residue in soil, on infected plants, and on seeds.\u00a0 During active growth, the pathogen produces masses of hyphae (stromata) which result in fruiting bodies (acervuli) that bear conidiophores, on the plant surface. Conidia (spores) are produced at the tips of the conidiophores and disseminated by wind, rain, cultivation tools, equipment, and field workers.\u00a0 \u00a0Conidia are transmitted to host plants.\u00a0 Humid, wet, rainy weather is necessary for infection to occur.\u00a0 These requirements in particular may limit the occurrence of the pathogen in California fields and subsequently, the pathogen may be more of a problem under controlled environments of greenhouses.\u00a0 Condia germinate, penetrate host tissue by means of specialized hyphae (appresoria) and invade host tissue.<\/p>\n<p style=\"padding-left: 30px;\"><em>Transmission<\/em>:\u00a0 Wind, wind-driven rain, cultivation tools, and human contact.<\/p>\n<p><strong><u>Worldwide Distribution<\/u>:<\/strong>\u00a0 Australia, India, Japan, New Zealand, USA (California) (Chowdappa et al., 2014; Damm, <em>et al<\/em>., 2012; Farr &amp; Rossman, 2015).<\/p>\n<p><strong><u>Official Control<\/u>:<\/strong>\u00a0 <em>Colletotrichum cymbidiicola <\/em>is considered a new record in North America and reportable to the USDA.<\/p>\n<p><strong><u>California Distribution<\/u>:<\/strong> San Diego and Santa Clara Counties (see \u2018Initiating Event\u2019).<\/p>\n<p>During the 1980s, CDFA plant pathologists identified <em>C. gloeosporioides<\/em> in <em>Cymbidium<\/em> sp. <em>(Alex French, California Plant Disease Host Index 2<sup>nd<\/sup> edition)<\/em>.\u00a0 The site of detection generally includes the southern coastal counties.
