DESCRIPTIONS OF MEDICAL FUNGI

Descriptions of Medical Fungi 225
Veronaea botryosa Ciferri & Montemartini
This genus is very similar to Rhinocladiella, however the conidia are typically twocelled.
Occasional skin infections have been reported from humans (Revankar and
Sutton 2010).
RG-2 organism.
Morphological Description: Colonies grow rapidly and are suede-like to downy,
greyish-brown to blackish-brown. Conidiophores are erect, straight or flexuose,
occasionally branched and are usually geniculate, due to the sympodial development of
the conidia. They are smooth-walled, pale to medium olivaceous-brown, up to 250 µm
long and 2-4 µm wide. Conidia are pale brown, two-celled, cylindrical with a truncated
base, smooth-walled or slightly verrucose, 5-12 x 3-4 µm.
Molecular Identification: Arzanlou et al. (2007) used D1/D2 and ITS sequence data
in a phylogenetic revision.
References: Ellis (1971), de Hoog et al. (2000, 2015), Revankar and Sutton (2010).
