Abstract
The description of Phytophthora macrochlamydospora
J.A.G.Irwin is emended, following further taxonomic studies with additional
isolates of the organism.
Phytophthora macrochlamydospora is a Group VI
Phytophthora species, producing non-papillate sporangia,
and sex organs in paired culture with
Phytophthora cambivora (Petri) Buisman,
A1 mating type. Sex organs have never previously been
described for P. macrochlamydospora, and this research
has shown that P. cambivora A1
induces selfing in P. macrochlamydospora. Antheridia of
P. macrochlamydospora are always amphigynous.
Phytophthora macrochlamydospora produces large (up to 90
µm), thick-walled chlamydospores that distinguish it from all other
Group VI species.
