Studies in the biochemistry of micro-organisms. 87. Dihydrogladiolic acid, a metabolic product of Penicillium gladioli Machacek

The Penicillium gladioli series in the subsection Fasciculata of the Asymmetrica section of species of Penicillium is at present represented by a single well defined species, P. gladioli Machacek (Raper & Thom, 1949, p. 474). Wakefield & Moore (1936), however, prefer to describe the species as P. gladioli McCulloch & Thom. P. gladioli is a common cause of the PeniciUium rot of gladiolus corms and is occasionally responsible for serious destruction of the-corms in storage.
