In these collections, as well as in two others from Colorado (U.S.A.) at 2400 and 2600 m and two from British Columbia and Saskatchewan, the germ pore on the conidia is mostly in an equatorial position and only rarely just above the basal scar. In the type collection of Streptothrix mounceae Sumstine (= Conoplea fusca) from Western Ontario, the germ pore is mostly just above the base but occasionally equatorial. In European and eastern North American collections the conidial wall is smooth to inconspicuously roughened but in collections from Australasia and western North America the roughening is somewhat more evident.
