A review of literature, with special reference to some recent publications in Spain and Portugal [cf. For. Abstr. 11 (Nos. 1468, 2268)]. The author concludes that Phytophthora cinnamomi plays a great part in disease of Chestnut in Spain, Portugal, France and Italy, and elsewhere in southern Europe, and is probably the major cause of death in the more southerly regions. P. cinnamomi has a considerable range of hosts. It has been found to attack Castanea sativa, Juglans regia, Pseudotsuga taxifolia, Quercus robur, Q. suber, Betula alba, Cedrus atlantica, Abies nordmanniana, A. alba, A. sibirica and Castanea crenata var. tamba. A close watch on Douglas Fir in the U.S.A. seems advisable in case a strain of the fungus should encounter and attack it. In contrast P. cambivora has only been found on Castanea sativa and C. crenata var. tamba.
