In Ascotricha chartarum (C. Zopfii) on the rind of Piscidia erythrina (Boulanger, 1897), two imperfect forms have been discovered, one a Sporotrichum type with smooth, hyaline conidia (Fig. 173, 4) and a Dicyma type with echinu

These, on dark-colored, sympodially branched conidiophores (Fig. 173, 2), appear deceptively like the sterile bristles on the neck of the perithecium. In other Chaetomieae, other conidial forms have been noted (thus Verticillium, etc.)..
