Abstract A description is provided for Colpoma crispum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: On dead, rather brittle twigs of Picea abies, but usually attached but sometimes fallen by the time ascomata contain ascospores. Probably involved in self-pruning of the tree, but associated with lichen colonies unlike species of Therrya on Pinus (IMI Descriptions 1297 and 1298), and Colpoma on Quercus (IMI Description 942) which occur on twigs without lichen colonies. HOSTS: Juniperus virginiana (twig), Larix sp. (bark, twig), Picea abies (bark, twig), Picea sp. (bark), Pseudotsuga menziesii (twig). GEOGRAPHICAL DISTRIBUTION: Germany, Italy, Sweden, UK (England, Scotland, Wales), Ukraine, USA (Oregon). Unsuccessful searches in north-west Poland. Altitude records exist up to 950m (Ukraine). TRANSMISSION: By air-borne ascospores in humid conditions. In the temperate northern hemisphere, ascocarps probably mostly open in late summer and early autumn.

Abstract A description is provided for Rhynchosphaeria cupressi. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Cupressus macrocarpa, C. lusitanica, C. arizonica, C. torulosa, Cupressocyparis lawsoniana, Juniperus procera, Thuja orientalis. DISEASE: Stem and branch canker of young trees. Cankers are associated with profuse resin flow and in advanced states, a flattened, winged condition of the tissue may be produced. Cankers may girdle and kill young trees. GEOGRAPHICAL DISTRIBUTION: North America (USA); Africa (Kenya, Uganda, Tanzania, Malawi, Rhodesia, South Africa); Australia and Oceania (New South Wales, Queensland, Victoria, Tasmania, South Australia, New Zealand); Asia (India (Bakshi et al., 1970)). TRANSMISSION: Conidia and ascospores are released under moist conditions and dispersed by a splash take-off mechanism, after which they have a limited air-borne range (33: 191). Long distance spread is probably effected by human agencies.

Pollen Types

The pollen morphology of seven species, varieties and forms of Cupressaceae from eastern Canada and northeastern United States was studied by light microscopy, following acetolysis, to improve the identification of these taxa in Quaternary fossil sediments. Taxodium distichum (Taxodiaceae), which is also present in the study area, was included for comparison. Four pollen types were defined: Juniperus communis – Thuja occidentalis, Chamaecyparis thyoides, Juniperus horizontalis – Juniperus virginiana, and Taxodium distichum. Five shapes of pollen grains exist: whole, slightly split, opened in a "V" shape, spindlelike, or split in halves. All shapes are found in all species, in varying proportions, and represent different stages of hydration in Cupressaceae pollen type. The absence or presence of these shapes cannot be used as an identification criterion for the different species. A pollen identification key, applicable to fossil sediments and combining characters based on shape, size and other morphological features of acetolysed grains, is proposed and allows to differentiate all the species from one another, with the exception of Juniperus horizontalis and Juniperus virginiana.

Abstract A description is provided for Diplodia pinea. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Pinus species. Also on Abies excelsa, Araucaria cunninghamii, Chamaecyparis lawsoniana, Cupressus macrocarpa, Cupressus lusitanica, Cupressus sempervirens, Picea abies, Pseudotusga menziesii, P. taxifolia and Thuja orientalis[Platycladus orientalis]. DISEASES: Tip and twig blight, stag-head, red top, bud-wilt and seedling collar rot of conifers. Causes stunting of new growth, browning of needles, bending or curling of young shoots and discoloration and death of parts of the crown. Also affecting germination of Pinus seed and causing blight and dieback of coniferous seedlings in the nursery. Frequently found as a wound parasite of injured or weak trees causing bark cankers and dieback of branches and as a saprophyte causing blue-stain of sap-wood of fallen or freshly cut timbers (17: 150; 36: 436; 41: 339). GEOGRAPHICAL DISTRIBUTION: Africa (Kenya, Malawi, Mauritius, Mozambique, Rhodesia, S. Africa, Tanzania, Uganda); Asia (Japan, Malaysia, Thailand); Australasia & Oceania (Australia, New Zealand); Europe (Austria, Belgium, France, Germany, Italy, Portugal, Rumania, Spain, Sweden, U.K.); North America (Canada, U.S.A.); Central America & West Indies (Jamaica), South America (Argentina, Brazil, Chile, Paraguay). (CMI Map 459, 1969). TRANSMISSION: The pathogen is disseminated as spores by wind, rain and in fluid secreted by the pine spittle-bug, Aphrophora parallela and as mycelium on seed of Pinus (16: 219; 21: 398). Infection may take place through natural infection courts such as leaf traces or cones and cone-stalks (5: 708; 48, 3187) as well as through living tissues following wounding (31: 1; 44, 889; 48, 3187) or damage from hail (8: 535; 16: 219; 20: 150), frost (21: 398; 40: 388) or insects (pine spittle-bug, 21: 398; bark beetles, Myelophilus piniperda[Tomicus piniperda], 14: 727) or attack by rust, Cronartiurn ribicola, causing progressive wilt in Pinus halepensis (25: 493) or by drought (14: 65) or other unfavourable growing conditions (13: 426, 553; 16: 148). Gilmour found that the amount of infection in P. radiata appeared to be correlated with trunk wounding and varied with the type of pruning tool used: secateurs, 12%; axe, 48%, slasher, 68% (44, 889). The pathogen may persist in infected tissues up to 400 days (48, 3187) and is commonly saprophytic on forest debris which provides a source of abundant spores during periods of rain (41: 339).

Здійснено інтегральне аутфітосозологічне оцінювання 41 виду деревних інтродуцентів відділу Pinophyta, які ростуть у ботанічному саду Чернівецького національного університету ім. Юрія Федьковича в умовах відкритого ґрунту. Відповідно до значень вирахуваного для кожного виду аутфітосозологічного індексу досліджувані дендроекзоти віднесено до чотирьох аутфітосозологічних класів (II-V); найбільше видів (27) увійшли до ІІІ класу. Для рослин кожного із аутфітосозологічних класів охарактеризовано ознаки, які найістотніше впливають на фітосозологічну цінність видів: категорія раритетності у Червоному списку МСОП, фітогеографічне та історичне значення, регіональна репрезентативність та кількість штучних природоохоронних об'єктів у межах Чернівецької області, де росте той чи інший вид. Зокрема, найчастіше у дендропарках, парках-пам'ятках садово-паркового мистецтва та у складі пам'яток природи Чернівецької області трапляються Thuja occidentalis L. (30 місцезростань), Pinus strobus L. (22), Platycladus orientalis (L.) Franco (19 місцезростань), і в межах 12-14 природоохоронних об'єктів – Pinus nigra J. F. Arnold, Ginkgo biloba L., Chamaecyparis pisifera (Siebold & Zucc.) Endl. Відзначено, що 51,2 % із досліджуваних видів трапляються, окрім ботанічного саду Чернівецького національного університету, також у дендропарках, парках-пам'ятках садово-паркового мистецтва та пам'ятках природи місцевого значення Чернівецької області. Раритетні види деревних інтродуцентів відділу Pinophyta цінні як резерв генетичного матеріалу. Тому особливої охорони потребують ті з них, які перебувають під загрозою зникнення (категорія раритетності у Червоному списку МСОП – CR, EN та VU), а також ті, що увійшли до ІІ аутфітосозологічного класу (Taxodium distichum (L.) Rich., Sequoiadendron giganteum (Lindl.) J. Buchholz, Metasequoia glyptostroboides Hu & W. C. Cheng, Picea koyamae Shiras.), та частина видів, віднесених до ІІІ класу (зокрема, ті з них, які представлені 1-2 особинами лише у ботанічному саду Чернівецького національного університету, і не здатні розмножуватися насіннєвим шляхом). Під час розроблення рекомендацій з ефективної охорони досліджуваних деревних інтродуцентів варто звертати увагу на екологічні вимоги видів, оскільки від цього значною мірою залежить успішність росту і розвитку інтродуцентів.
