            <p> Colletotrichum juglandis X. Wei &amp; J.X. Deng ,  sp. nov. Fig. 3 </p>
            <p>MycoBank No: 843086.</p>
            <p> Etymology: In reference to the host genus name,  Juglans . </p>
            <p>  Type. China, Hubei Province, Yichang city, Xingshan county on infected leaves of  Juglans regia . 11  July , 2019, J  .  X. Deng (ex-type culture YZU 191277)</p>
            <p>Description: Colonies on PDA attaining 47–52 mm diam. after 7 days at 25 °C, whitish to gray, dense, aerial mycelium with masses of conidial ooze. Conidia on SNA unicellular, hyaline, smooth-walled, aseptate, straight, subcylindrical to fusiform with one end round and one end slightly acute, 6–15×2–5 μm (av.: =10.8×4.1, n =50). Appressoria single, brown to dark brown, smooth-walled, variable in shape, irregular unlobed or slightly lobed, 6–17× 4–10 μm (av.: =9.3×6.4, n =30). Chlamydospores formed laterally on hyphae. Setae absent. Sexual morph not observed.</p>
            <p> Materials examined: China, Hubei Province, Yichang City, Xingshan County, Walnut orchard, from the leaf of  Juglans regia anthracnose 11 July, 2020, X. Wei, living cultures YZU 191277 and YZU 201192. </p>
            <p> Note: This species belongs to  C. acutatum species complex (Fig. 1) and forms a mono-lineage in a clade comprising  C. chrysanthemi ,  C. cosmi ,  C. guajavae ,  C. nymphaeae ,  C. scovillei , and  C. walleri with 1.0/100% (PP/BS) values. It is phylogenetically close related to  C. nymphaeae ,  C. guajavae ,  C. scovillei and  C. chrysanthemi . Morphologically, it is readily differentiated with  C. chrysanthemi by conidia shape and distinct from the other three species by producing larger appressoria (Table 2). In addition,  C. guajavae and  C. scovillei produce conidia with acute ends (Damn et al. 2012a), which is not observed in this species. </p>
            <p>Pathogenicity tests</p>
            <p> Pathogenicity tests revealed that  Colletotrichum juglandis sp. nov. from  Juglans regia could induced necrotic symptoms on living leaves by the spore suspension of isolate YZU 191277. After 7 days, the disease symptoms caused by spore suspension were around 4.3 mm in diameter (Fig. 3B), while symptomless on controls. After re-isolation, the same pathogen was obtained and identified based on morphology. </p>
