Juglanconis juglandina (Kunze) Voglmayr & Jaklitsch, Persoonia 38: 144 (2017). Notes. Juglanconis was introduced by Voglmayr et al. (2017) to accommodate previous Melanconium juglandinum , M. oblongum and M. pterocaryae based on morphology and DNA data of type materials. The genus is restricted to one host in Juglandaceae , which is identified by having perithecial ascomata, 8-spored asci with an apical ring, hyaline, bicelled ascospores in the sexual morph; and acervular conidiomata, brown conidia with gelatinous sheaths in asexual morph ( Voglmayr et al. 2017 ). Juglanconis includes five species ( J. appendiculata , J. japonica , J. juglandina , J. oblonga and J. pterocaryae ) ( Voglmayr et al. 2019 ), of which J. juglandina and J. oblonga are common pathogens in Juglans spp. in China ( Fan et al. 2018b ).
