Monodictys arctica, a new hyphomycete from the roots of Saxifraga oppositifolia collected in the Canadian High Arctic

Abstract: Monodictys arctica sp. nov. is described on the basis of nine isolates obtained from the roots of eight separate collections of Saxifraga oppositifolia from Ellesmere Island, Nunavut, Canada. Conidia are multicelled, smooth, darkly pigmented, and globose, oblong, ellipsoidal, or pyriform t...

Description
Summary:Abstract: Monodictys arctica sp. nov. is described on the basis of nine isolates obtained from the roots of eight separate collections of Saxifraga oppositifolia from Ellesmere Island, Nunavut, Canada. Conidia are multicelled, smooth, darkly pigmented, and globose, oblong, ellipsoidal, or pyriform to irregularly shaped or dichotomously branched, consisting of a blastically produced basal cell and a distal proliferation of up to 24 cells arising from meristematic growth. Analyses of SSU and ITS sequences indicate the species is unique but has an affinity to the loculoascomycete taxon Leptosphaeria dryadophila.
