Pseudocryphonectria has typical orange cryphonectriaceous stromata, which turns purple the 3% KOH and yellow in lactic acid. This genus is characterized by its dimorphic conidia from the same conidioma, which is different from the other genera of Cryphonectriaceae ( Chen et al. 2013, 2016, 2018; Beier et al. 2015; Jiang et al. 2020).
