Note：
This species has two conidial states, Sclerophoma magnusiana (Smerlis, 1970) and Dothichiza pithyophila (Butin, 1964). The Taiwan specimen only produced a Hormonema state in culture. Sivanesan (1984) reported Sclerophoma and Hormonema of this species have occasionally a vertical septum in one to three cells for this species. Barr (1972) described ascospores of this species have occasionally a vertical septum in one to three cells. In Taiwan specimen, only transverse septa were observed.
