Abstract Pythium mastophorum, not previously recorded
in New Zealand, was isolated from soil from two Auckland strawberry-growing
sites. The oospores have characteristic regular conical mammiform spines,
readily distinguishing it from
Pythium spp. other than
P.
polymastum. A brief study of these isolates was carried out to determine
how the pathogenicity to vegetable seedlings of
P. mastophorum compared
with that of other
Pythium spp. They were found to be moderately
pathogenic to a range of these seedlings.
