The acremonium-like asexual morph of this species was obtained in culture and sequenced. The genus is placed in the Nectriaceae based on ascomata changing colour in 3% KOH or lactic acid as defined by Rossman et al. (1999), acremonium-like asexual morph and phylogenetic analysis of its LSU sequence. Morphologically, Chrysonectria is primarily characterized by gregarious, corticolous, globose to subglobose, pale orange, non-stromatic ascomata with ascomatal surface covered by bright yellow hyphal elements arising from the subiculum, releasing orange yellow pigments in 3% KOH or yellow pigments in lactic acid}}
