Ulocladium
Species of Ulocladium should not be confused with other poroconidial genera such as Stemphylium, Alternaria, Bipolaris, Exserohilum, Dreschlera and Curvularia.
A human case of keratitis has been reported (Badenoch et al. 2006).
RG-1 organism.
Conidia of Ulocladium spp.
Morphological description:
Colonies are rapid growing, brown to olivaceous-black or greyish and suede-like to floccose. Microscopically, numerous, usually solitary, multicelled conidia (dictyoconidia) are formed through a pore (poroconidia) by a sympodially elongating geniculate conidiophore. Conidia are typically obovoid (narrowest at the base), dark brown and often rough-walled. Seven species have been described, all being saprophytes.
Molecular identification:
ITS sequencing is sufficient for genus identification (Badenoch et al. 2006) and Woudenberg et al. 2013).
