Abstract A description is provided for Lophodermium juniperinum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Reported from many species of Juniperus, especially J. communis. Also reported from Chamaecyparis spp. and Libocedrus decurrens[Calocedrus decurrens]. DISEASE: The pathogenicity of L. juniperinum has not been clearly established. Various authors (e.g. Peace (42, 155), Lanier (58, 2948), Parmelee (62, 4192)) have included it in lists of parasites of Juniperus, but none presented any firm evidence of pathogenicity. However, Darker (12, 254) could find no reason to suspect that L. juniperinum was other than a saprophyte. At least in Scotland, the ascomata develop on needles still attached to the tree, and mature between May and July. GEOGRAPHICAL DISTRIBUTION: Very widely distributed in temperate regions. Recorded from Austria, Belgium, Canada, Czechoslovakia, Denmark, Eire, Finland, France, Germany, Hungary, Iceland, Italy, Norway, Poland, Roumania, Sweden, Switzerland, UK and USA. TRANSMISSION: Unknown. Similar fungi have air-dispersed spores directly infecting host leaves.

Endophytic fungi were isolated from foliage of four host species of Cupressaceae sampled from 19 sites in Oregon. Chamaecyparis lawsoniana and Thuja plicata showed high overall rates of infection (30–50%) while Calocedrus decurrens and Juniperus occidentalis showed lower rates (10–35%). For any particular host, samples from homogeneous stands with a closed canopy showed higher infection rates than those from mixed stands with an open canopy. For a given tree, infection rates tended to increase with increasing foliage age and decreasing distance from the trunk (exceptions are noted in the text below). The most commonly isolated endophytes include Linodochium sp. and Geniculosporium sp. on C. decurrens; Scolecosporiella sp., Nodulisporium sp., Geniculosporium sp., and Chloroscypha alutipes on C. lawsoniana; Retinocyclus abietis anamorph and Hormonema sp. on J. occidentalis; and Chloroscypha seaveri on T. plicata.

Abstract Results are reported from a provenance study of incense-cedar (Calocedrus decurrens), a tree species native to forested regions of Oregon, California, and Baja California. Seedlings from six geographically distinct regions were measured over a 12 yr period in a common-garden study located near the center of the species' native range. In general, among-region genetic variation was small. However, differences in height, stem volume, and crown form between trees from the southernmost region sampled and trees from the other five study regions were large and significant. Further studies of within-population genetic variation are recommended prior to initiating any tree improvement activities. West. J. Appl. For. 9(4):113-117.
