P. agathidicida sporangium Globose to ovoid-ellipsoid, papillate sporangium	P. agathidicia oogonia Light micrograph of P. agathidicida oospore (Scale bar equals 15 µm)	Comparative gametangial morphology of Phytophthora Clade 5 species Comparative gametangial morphology of Phytophthora Clade 5 species, with SEM (top) and light microscopy (bottom). P. heveae has smooth walled oogonia with funnel-shaped, amphigynous antheridia. P. agathidicida has mildly stipulate oogonia with globose amphigynous antheridia. P.cocois has mildly bullate oogonia with reflexed amphigynous antheridia. P. castaneae has coarsely bullate oogonium with rugose protuberances and narrow amphigynous antheridia (Weir et al. 2015).
