“…As espécies deste gênero são, comumente, patogênicas a hospedeiras vegetais, mas a ocorrência de infecção por Colletotrichum também foi identificada em tartaruga marinha (Lepidochelys kempi Garman) (MANIRE et al 2002) e, algumas espécies de Colletotrichum, podem ser patogênicas a humanos, causando queratomicoses (queratites) e doenças dermatológicas, principalmente em pessoas imunocomprometidas (SUTTON 1999, SHIVAPRAKASH et al 2011, HOWARD et al 2016, FERNANDEZ et al 2002, PANIZ-MONDOLFI et al 2021). Existem relatos de espécies de Colletotrichum causando infecções em insetos, como: C. fioriniae (Marcelino & Gouli) Pennycook em cochonilhas-da-cicuta (hemlock scale) (Fiorinia externa Ferris) em Nova Iorque; e, C. gloeosporioides em cochonilhas de citros (Orthezia praelonga Douglas), no Brasil (MARCELINO et al 2008, 2009ab, DAMM et al 2012b, WYNNS et al 2020.…”

The genus Colletotrichum is widely distributed, mainly in regions tropical and subtropical, however, some species are adapted to temperate regions. Based on the perception of its scientific and economic importance, Colletotrichum spp. is among the most important phytopathogenic fungi in the world. Its importance is given, mainly, for causing symptoms of anthracnose in several species of plants, mainly affecting the production of fruits of high value crops in the market, such as: strawberry, mango, citrus, avocado and banana, and crops of grains, such as: beans, soybeans, sorghum and corn. This work gathered some of the main information published until 2022, mainly on the taxonomy of the genus Colletotrichum, in a chronological line of the main events from the 18th to the 21st centuries, with the objective of describing its morphology, geographic distribution, pathology, style of life, genetics and phylogeny, aiming to subsidize complementary studies of the genus

“…It has been reported that there are globally 16 species of Colletotrichum spp. complex [17][18][19][20], which can infect many cash crops, fruit trees, vegetables, and ornamental plants, causing symptoms such as wilting, leaf lesions, and fruit rot, resulting in severe economic losses [21][22][23][24], and some species can even directly affect human health; for example, C. chlorophyti and C. gloeosporioides are capable of causing fungal inflammation of the cornea [25,26]. Colletotrichum spp.…”

Vaccinium corymbosum L., commonly known as blueberry, is a valuable small fruit tree in terms of its economic significance and is primarily found in China within the regions of Heilongjiang and Jilin provinces. Additionally, it thrives in the areas spanning the middle and lower reaches of the Yangtze River. Beyond their economic value, blueberries play a crucial role within forest ecosystems, serving as a significant energy source and source of nutrients. Their presence contributes significantly to fostering stability, enhancing biodiversity, and acting as an indicator of environmental quality within forest ecosystems. Since August 2022, an unknown leaf disease has been found on a large scale in blueberry fields in Nanjing, Jiangsu Province, China. The disease causes leaf curling, wilting, and even early defoliation, severely reducing the yield and production value of blueberries. The pathogenicity test confirmed the virulence of the isolates (NG5-1, NG5-2, NG5-3, NG5-4, N2-1, and N2-2) against V. corymbosum. The two pathogens were identified as Colletotrichum fructicola and C. aenigma by observing the morphological characteristics of the isolates and combined with multilocus phylogenetic analyses (ITS, CAL, ACT, TUB2, ApMat, and GAPDH). Blueberry anthracnose, caused by C. aenigma, is the first report of this disease in China. The biological characteristics of C. aenigma were investigated under different conditions, including temperature, pH, light conditions, culture medium, and carbon and nitrogen sources. The optimal temperature for growth was determined to be within the range of 25–30 °C; C. aenigma exhibits optimal growth at a pH of 7–8. Mycelial growth is favored under conditions of partial light, whereas complete darkness promotes spore production. It was found that PDA medium was the most favorable medium for C. aenigma mycelial growth, and MM medium was the best medium for spore production; the most suitable carbon sources for colony growth and spore production were sorbitol and glucose, respectively, and the most suitable nitrogen source was peptone. This study furnishes a theoretical foundation for a more scientifically informed approach to the prevention and control of anthracnose on V. corymbosum.
