Notes.

Juglanconis oblonga (previous Melanconium oblongum ) is associated with canker disease of Juglandaceae hosts in North America and Southeast Asia ( Graves 1923, Voglmayr et al. 2017, Fan et al. 2018b). This species is similar to J. juglandina in disease symptoms but can be distinguished by its longer conidia (22 × 12.5 compared to 20 × 13 μm) and DNA sequence data ( Fan et al. 2018b). This species is a common pathogen causing walnut canker in China ( Fan et al. 2018b).
