P. pseudotsugae colony morphology on PDA P. pseudotsugae colony growth on PDA agar	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).

The tissues around the initial infection at the base or along the needle senesce, and change yellow and then brown as indicated by the arrows before the needles cast.
