Abstract A description is provided for Elytroderma torres-juanii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus halepensis, P. brutia. DISEASE: Needle blight of pines. Symptoms become visible on second year needles which in late summer assume a yellowish and later a brown colour. Discoloration starts from either end of the needle and may not extend along the whole needle. The boundary between the discoloured part and the remainder which stays green is sharply demarcated. Usually only one of the needles of the two-needle bundle is affected. Often the base of the discoloured needle next to the sheath remains green. Third-year and fourth-year needles are brown and carry ascocarps of the fungus. GEOGRAPHICAL DISTRIBUTION: Europe (Greece, Spain). TRANSMISSION: By air-borle ascospores in wet weather.

NOTE: This article was published in a former series of GEUS Bulletin. Please use the original series name when citing this article, for example: Christiansen, F. G., Boesen, A., Dalhoff, F., Pedersen, A. K., Pedersen, G. K., Riisager, P., & Zinck-Jørgensen, K. (1997). Petroleum geological activities onshore West Greenland in 1996, and drilling of a deep exploration well. Geology of Greenland Survey Bulletin, 176, 17-23. https://doi.org/10.34194/ggub.v176.5055 _______________ The 1996 summer season saw continued petroleum geological activities in the Disko–Nuussuaq area, onshore West Greenland. These took the form of a geological field project led by the Geological Survey of Denmark and Greenland (GEUS), and continued commercial exploration by grønArctic Energy Inc. (grønArctic). In the second year of their licence, grønArctic carried out an airborne geophysical programme early in 1996 and drilled a c. 3 km deep exploration well on Nuussuaq, GRO#3, in the late summer (Fig. 1). Although the detailed results from grønArctic’s exploration are confidential (apart from the information made available at conferences and in press releases), it is evident that knowledge of the Nuussuaq Basin has greatly increased in recent years and that the basin has considerable exploration potential of its own (see Christiansen et al., 1995b, 1996a). The activities by GEUS and the exploration by grønArctic will significantly improve the understanding of the petroleum system of the basin; available data from the 1996 activities have shed light on the types and distribution of oils, source rocks and potential reservoir units.

Abstract A description is provided for Ascochyta desmazieresii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Lolium multiflorum and L. perenne. DISEASE: Glume and leaf spot of Italian and perennial ryegrasses. At first leaf lesions start as small purplish or chocolate-brown spots with a distinct red-purple margin. With time these enlarge, become irregular or elliptical, up to 5 mm long and distinctly visible on both sides of the leaves. Finally the centres of older lesions fade to fawn to straw yellow with numerous pycnidia immersed within the leaf tissue on both sides of the leaves but usually abundant pycnidia occur on the lower side. GEOGRAPHICAL DISTRIBUTION: Asia (Japan); Europe (Belgium, Czechoslovakia, Denmark, France, Irish Republic, UK); N. America (USA, California, Oregon, Washington); S. America (Chile, Brazil). TRANSMISSION: No specific studies reported; infection is presumably spread by air-borne conidia in wet weather or heavy dews. The fungus is also probably carried over on crop residues and debris in soil.

Abstract A description is provided for Isthmiella faullii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Apparently confined to Abies balsamea. DISEASE: Causes a needle blight of Abies balsamea. According to Darker (1932), it 'is the commonest and most destructive of the Hypodermataceae on Abies balsamea in eastern North America'. It is particularly damaging to seedlings and juvenile plants. In northern Ontario, from where the disease was originally identified, infection occurs during the summer, but signs of the disease do not appear until the following spring, when needles become brown and conidiomata develop, conidia being discharged in July, and shortly after this ascomata begin to form, maturing in July of the following year. GEOGRAPHICAL DISTRIBUTION: Reported from Canada: Nova Scotia, Ontario, Quebec and USA: Michigan and New Hampshire. TRANSMISSION: Through air dispersal of ascospores, which directly infect the leaves (Darker, 1932).

Abstract A description is provided for Microsphaera penicillata. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On species of Alnus, Betula, Syringa, Lathyrus, sweet peas and numerous other hosts (Saknon, 1900; Stevens, 1925; 39: 739; 41: 175) DISEASES: Powdery mildew of alder and lilac. Forms a white to grey floury appearance on the surface of broad leaves of many hard wood trees. It is more prevalent on sweet peas than Erysiphe pisi (CMI Descript. 155) in North America in spring when temperature and humidity are fluctuating. The foliage may be malformed, dropping prematurely or drying out and shrivelling. It is also prevalent on lilac in late summer and autumn, sometimes in dry seasons almost completely covering the foliage, but generally too late in the season to cause serious damage. Young leaves are more susceptible. GEOGRAPHICAL DISTRIBUTION: World-wide on alder and lilac and occasionally occurring on numerous other hosts. Distributed generally in North America and Europe, also reported from Chile, China, India and Japan (Salmon, 1900, 39: 739; 41: 175). TRANSMISSION: Spores wind borne.

Abstract A description is provided for Cryptodiaporthe populea. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Poplar, willow. A wide range of poplar species are more or less susceptible, with members of the tacamahacca and algeros groups principally affected. Populus alba var. pyramidalis is very susceptible in Britain and P. alba and P. tremula are tolerant; complete resistance is unknown in the genus: The fungus has been recorded on cricket bat willow in Belgium. DISEASE: Dothichiza canker, Dorhichiza dieback, poplar canker. The conidial state is the form of this fungus most commonly found associated with the dieback or canker of poplar. The fungus is a wound parasite unable to invade sound bark tissues, although very small wounds, such as scars left by bud scales, may permit infection (38, 341). Infection usually occurs in the winter, when bark moisture and turgor are lowest (36, 673; 37, 684). First signs are a discoloration of the cortex under the bark, which develops to a sunken, dead patch of bark, often at the base of twigs or at the junction of first-year and second-year wood. The lesion may have an unpleasant odour and later develops black, globular, pycnidia on the surface. The lesion may heal over in a single season but it can spread to cause severe damage or death of the host. Injury is believed to be due to toxin formation as well as physical girdling by the canker (35, 797; 38, 103). The crowns of old trees or young plants in nurseries and plantations are mainly affected. The disease may be distinguished from that caused by Valsa sordida Nits. by its larger conidia and larger and less frequent stromata in infected tissues. GEOGRAPHICAL DISTRIBUTION: Europe (all western Europe excluding Portugal, Norway, Yugoslavia, Rumania, Bulgaria, Poland, Estonia, Ukraine and south-east Russia). Near East (Turkey, Cyprus). North America (east Canada, north-east USA). South America (Argentina) (CMI Map 344, ed. 2, 1968). TRANSMISSION: Mainly by airborne splash-dispersed conidia.
