Phacidium injestans P. Karsten sensu lato may be divided into two varieties: the Eurasian Ph. infestans var. infestans and the American‐Japanese variety Ph. infestans var. abietis Dearness. Ph. infestans var. infestans includes a northern and a southern group, both fruiting on two‐ and five‐needled pines, the northern also very seldom fruiting on Abies and Juniperus . Disease caused by the fungus, diaspores, resistance of the hosts, influence of snow cover and of ground vegetation, and control are dealt with in detail for the northern group. Ph. infestans var. abietis includes two formac speciales: the North American Ph. infestans var. abietis f. sp. abietis on Abies and Pseudotsuga , and the Japanese Ph. infestans var. abietis f . sp. piceae on Abies, Picea , and p inus .
