The fungus was isolated from living but discoloured needles of Pinus radiata. It did not fit the descriptions of any species described in a monograph of Calonectria and Cylindrocladium species (Crous 2002). Cultures were sent to the Centraalbureau voor Schimmelcultures, Utrecht, who considered it to be an undescribed species although it was morphologically similar to Cylindrocladium hurae (Linder & Whetzel) Crous and, based on beta tubulin sequence data, to C. retaudii (Bugnicourt) C. Booth/ C. multiseptatum Crous & Wingfield (P. Crous, pers. comm.). It has no pathological significance.
