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 Septoria cucurbitacearum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Cucumis melo, C. sativus, Cucurbita ficifolia (=C. melanosperma), C. maxima, C. moschata, C. pepo and Bryonia dioica (=B. cretica). DISEASE: Leaf spot of cantaloupe, cucumber, melon, pumpkin, squash and vegetable marrow. The visible symptoms are circular, olive brown lesions, prominent on the upper surface of the leaves. With the progress of the disease the spots enlarge, usually reaching 3-5 mm diam., occasionally 8 mm wide and soon dry up. Older lesions tend to turn white revealing several pycnidia embedded within the tissue. GEOGRAPHICAL DISTRIBUTION: Africa (Ethiopia, Kenya, Zambia); Australasia & Oceania (Australia); Europe (Bulgaria, Denmark, France, Germany, Hungary, Italy, Portugal, Rumania, USSR); North America (USA, Delaware, Massachusetts, New Hampshire, New York, Pennsylvania, Wisconsin). TRANSMISSION: Presumably by conidia disseminated by water splash in wet weather or heavy dews.

Abstract A description is provided for Bifusella linearis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus albicaulis, P. flexilis, P. monticola, P. strobus. DISEASE: Needle blight and needle cast of white pines, tar spot needle cast, Bifusella blight. The disease apparently occurs only under moist conditions, and since its effects are usually limited to defoliation of needles two or three years old, it is not devastating. Probably infects young needles but macrosymptoms do not show up until the following spring when needles become blighted from the tip part-way to the base. The disease tends to occur principally in the lower crown (47, 2867). GEOGRAPHICAL DISTRIBUTION: North America (Canada: British Columbia, Ontario, U.S.A. : California, Colorado, Idaho, Maine, Massachusetts, Minnesota, New Hampshire, New York, North Carolina, Pennsylvania, Washington, Wisconsin). TRANSMISSION: By air-borne ascospores in wet or humid weather.

Abstract A description is provided for Phaeoseptoria vermiformis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Triticale (Triticum × Secale), Avena (oats) and Triticum (wheat). DISEASE: Leaf spot of Triticale, wheat and oats. Lesions on leaves are irregular to elliptical, light brown to straw yellow. As infection progresses lesions enlarge to form blotches extending to the margins of leaves. GEOGRAPHICAL DISTRIBUTION: East Africa and North America (Mexico, Patzcuaro). TRANSMISSION: Presumably by conidia dispersed by water splash in wet weather or heavy dews. So far the mode of infection under natural conditions and the spread of the disease have not been investigated. It has been suggested that P. vermiformis might persist on native grasses in the field and this could serve as a source of inoculum in addition to the infected stubble or debris left over from previous years crop.

Abstract A description is provided for Sydowia polyspora. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Cupressus lusitanica, Juniperus sp., Picea engelmannii, P. excelsa, Pinus albicaulis, P. attenuata, P. khasya, P. caribaea, P. laricis, P. montizumae, P. murrayana, P. nigra, P. patula, P. pinaster, P. radiata, P. sylvestris. DISEASES: Pine leaf-blight and die-back, associated frequently with injury caused by the pine needle midge, Cecidomyia baeri Prell. The needles remain attached hanging downwards from the tree for some time. Complete defoliation may take place on severely affected shoots. Also common on needles of Corsican pine showing die-back due to unsuitable climatic conditions aided by Scleroderris lagerbergii[Gremmeniella abietina], and on Douglas fir attacked by aphids, Chermes cooleyi Gill. GEOGRAPHICAL DISTRIBUTION: Africa (Kenya, Tanzania); Australia & Oceania (Australia); Europe (Finland, France, Germany, U.K., U.S.S.R.); North America (Canada, U.S.A.). TRANSMISSION: Presumably by air-borne spores. In pine the pathogen first develops at the base of the pairs of needles where the gall midge, Cecidomyia baeri burrows (Peace, 1962) and on Douglas fir attacked by Chermes cooleyi the pathogen invades the carcases of the aphids and uses these as a food base before penetrating the stomata of the needle (47, 3240).
