Talaromyces systylus, a new synnematous species from Argentinean semi-arid soil

Abstract

The discovery of an interesting new synnematous Talaromyces species from Argentinean semi-arid soil has enlarged the number of synnema producing species. Talaromyces systylus sp. nov., phylogenetically distinct from other species in the genus, was characterized by the production of indeterminate synnemata on Malt Extract Agar and coarsely rough-walled, globose conidia and conidial chains associated in columns. Optimal growing temperature was 30 ºC. Talaromyces systylus was compared with other related species, morphologically and phylogenetically based on ITS, BenA and CaM markers.
