Summary

A reexamination of Physoderma maculare Wallroth the type species of the genus, on Alisma, confirms Clinton's (1902) account of the production of an epibiotic stage from resting spore zoospores. The latter on mature host tissue may also give rise to the endobiotic stage which bears resting spores. On seedlings, however, resting spore zoospores produce only epibiotic sporangia. The fungus could not successfully infect Sagittaria, a closely related host.
