Penicillium viticola, a new species isolated from a grape in Japan

A new monoverticillate Penicillium species (subgenus Aspergilloides Dierckx), Penicillium viticola, was isolated from a grape cultivated in Yamanashi Prefecture, Japan. Morphologically, P. viticola is characterized by the production of slightly roughened conidia, slightly roughened stipes, and rapid growth on 25% glycerol nitrate agar (G25N). This species is phylogenetically close to Penicillium angulare S.W. Peterson, E.M. Bayer & Wicklow, but differs with respect to colonial characteristics and conidia and penicilli morphology.
