Two new heterothallic Neosartorya from African soil

Abstract

Neosartorya nishimurae and N. otanii, two new heterothallic species isolated from African forest soil, are described and illustrated. Neosartorya nishimurae is characterized by its rapid growth on Czapek and malt extract agars, white cleistothecia, lenticular ascospores with two broad equatorial crests and echinulate convex surfaces, and large ellipsoidal conidia with a lobate-reticulate wall. Neosartorya otanii is characterized by its rapid growth on Czapek and malt extract agars, lenticular ascospores with two widely separated equatorial crests and tuberculate or lobate-reticulate convex surfaces, and globose to broadly ellipsoidal conidia with a micro-tuberculate wall.
