Some Species of Papulaspora Associated with Rots of Gladiolus Bulbs

SUMMARY

Associated with the rots of the bulbs of Gladiolus the writer has isolated the following species: Papulaspora Dodgei Conners, P. rubida Hotson (J. W.), P. appendicularis Hotson (H. H.), and P. coprophila (Zukal) Hotson (J. W.). Of these P. appendicularis is here described as new. These fungi are saprophytes living on the decayed bulb tissue caused by the primary infection of some other organism, in this case, Sclerotinia (Botrytis) sp., and by themselves do not cause a disease of the Gladiolus.
