Chalara inflatipes (Preuss) Sacc., C. insignis (Sacc., Rouss. & Bomm.) Hughes, and C. bicolor share some common features: the phialides of each species have multicellular, dark brown stalks, paler, rough-walled venters, and dark brown collarettes with somewhat circumferential roughenings towards the apex. C. bicolor may be distinguished from C. inflatipes by its 7-septate and longer conidia; in authenticated material of C. inflatipes the conidia are all 3- septate and measure 25-32.5 x 4.5-5.0 µm. In preparation from the type, and in two other collections of C. insignis preserved in DAOM, mature conidia are 7-septate and 32.5--46 X 6.0-7.2 µm; in C. bicolor the conidia are longer and slightly narrower.

Conidiophores usually in loose or compact clusters, more or less lageniform, brown, 125-160 µm long, composed of a 1- or 2-celled darker coloured stalk and a terminal phialide. Stalk usually 1-celled 9-18 µm long and 11-15 µm wide or 2-celled and 25-33 x 16 µm. Phialides more or less lageniform, irregularly and sparsely roughened, 110-140 µm long, 16-23 µm wide at the slightly inflated venter, merging into a cylindrical collarette which is 15-20 µm wide.
