Abstract A description is provided for Potebniamyces coniferarum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On living and dead branches, stems and leaves of conifers: Picea excelsa, Abies grandis, A. alba, Cedrus atlantica, C. deodara, C. libani, Larix leptolepis, L. decidua, L. russica, L. × eurolepis, L. occidentalis, Pinus strobus, P. sylvestris, P. radiata, P. canariensis, Pseudotsuga menziesii, P. douglasii, P. glauca, P. taxifolia, Sequoia gigantea, S. wellingtonia, Tsuga heterophylla, T. canadensis. DISEASE: A facultative pathogen which causes twig die-back and basal canker on young shoots and elongate cankers on older stems. The latter may be annual or may persist for three or four years. Larix, Pinus and Pseudotsuga are particularly susceptible. The fungus also causes blue sap stain of conifer timber. GEOGRAPHICAL DISTRIBUTION: Europe (UK, France, Italy, Germany, Belgium, Netherlands, Czechoslovakia, Denmark, Norway, Sweden, USSR, Romania, Iceland); North America (N.E. and N.W. USA, Canada); New Zealand. (CMI Map 320, ed. 2, 1968) TRANSMISSION: By splash-dispersed conidia and possibly by ascospores.

Leaf angle distributions are important in assessing both the flexibility of a plant's response to differing daily and seasonal sun angles and also the variability in the proportion of total leaf area visible in remotely sensed images. Leaf angle distributions are presented for six conifer species, Abies grandis (Dougl. ex D. Don) Lindl., Thuja plicata Donn. ex D. Don, Tsuga heterophylla (Raf.) Sarg., Pseudotsuga menziesii (Mirb.) Franco, Picea sitchensis (Bong.) Carr. and Pinus contorta Dougl. ex Loud. var. latifolia. The leaf angles were calculated by measuring four foliar quantities, and then the distributions of leaf angles are cast in three forms: distributions of (i) the angle of the long axis of the leaf from the vertical for the range 0–180°; (ii) the angle of the long axis of the leaf for the range 0–90°; and (iii) the angle of the plane of the leaf for the range 0–90°. Each of these are fit to the ellipsoidal distribution to test the hypothesis that leaf angles in conifers are sufficiently random to fit the ellipsoidal distribution. The fit was generally better for planar angles and for longitudinal angles between 0° and 90° than for longitudinal angles between 0° and 180°. The fit was also better for Tsuga heterophylla, Pseudotsuga menziesii, Picea sitchensis, and Pinus contorta than for Abies grandis and Thuja plicata. This is probably because Abies and Thuja are more shade tolerant than the other species, and so the leaves in Abies and Thuja are preferentially oriented near the horizontal and are much less random than for the other species. Comparisons of distributions on individual twigs, whole branches, entire trees, and groups of trees were done to test the hypothesis that angle distributions will depend on scale, and these comparisons indicated that the apparent randomness and goodness-of-fit increased on passing to each larger unit (twigs up to groups of trees).Key words: conifer, leaf angles, ellipsoidal distribution.

Podosphaera Leucotricha

Abstract A description is provided for Podosphaera leucotricha. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Malus spp., chiefly on M. pumila (apple), peach (Prunus persica), quince (Cydonia ualgaris) and Photinia spp. also attacked (Hirata, 1966). Also reported on almond fruit (43, 2544). DISEASE: Powdery mildew of apple. GEOGRAPHICAL DISTRIBUTION: Africa (? Kenya, Rhodaia, South Africa, Tanzania); Asia (China, India, Israel, Japan, U.S.S.R.); Australia and New Zealand, Europe (widely distributed) North America (Canada and U.S.A.); South America (Argentina, Brazil, Chile, Colombia, Peru). (CMI map 118). TRANSMISSION: Overwinters on host as dormant mycdium in blossom buds. The role of deistothecia in overwintering is doubtful. Spread by wind-borne conidia (Anderson, 1956).
