Index Fungorum number: IF 7737

Type species: Colletotrichum lineola Corda, Deutschlands Flora (Nürnberg): 41 (1832)

Notes: Colletotrichum was introduced by Corda (1831), with C. lineola as the type species, and it is the sole member of Glomerellaceae ( Glomerellales, Sordariomycetes) (Hyde et al. 2020). The sexual morph of this genus is characterized by glomerella-like, semi-immersed to aerial, sphaerical, dark-brown ascomata, with or without setae, cylindrical asci contain clavate, elongate to fusiform, multi-septate ascospores (Jayawardena et al. 2016a).The anamorph of Colletotrichum is characterized by having hyaline conidiophores formed on aerial mycelium, cylindrical to clavate conidiogenous cells, conidia cylindrical to clavate, apically round, granular, sepatae or aseptate (Diao et al. 2017). Dean et al. (2012) proposed that Colletotrichum is one of the most common and important plant pathogenic genera generally causing diseases such as anthracnose, seedling blights, and red rot on various plants, include economical crops, around the world (Silva-Rojas & Ávila-Quezada 2011, Wang et al. 2021). Some Colletotrichum species were also introduced as endophytes and saprobes (Jayawardena et al. 2020). In addition, Colletotrichum species have been identified as human pathogens or entomopathogens (Damm et al. 2012, Natarajan et al. 2013, Talhinhas & Baroncelli et al. 2021). Currently, Index Fungorum (2022) lists over 1000 species epithets of Colletotrichum (Kirk et al. 2015) .
