The Phytophthora taxonomic system has been based on morphological characteristics of the globose oogonia with paragynous antheridia, chlamydospore

has been avoided and (b) dispersal propagules have reached it.
A large quantity of chlamydospores
was produced in the rhizoplane (Figure 1B), and the hyphae of the fungus penetrated into cells of the root cortex (Figure 1C).
Isolates which produced chlamydospores
on rice and corn meal agar were 28 (47%) in which two were not identified as C.
