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 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 Microplitis Foerster is a highly diverse and cosmopolitan genus within Microgastrinae (Hymenoptera, Ichneumonoidea, Braconidae). Microplitis ceratomiae Riley, a widely distributed North American species, exclusively attacks sphingid caterpillars. In this paper, M. ceratomiae is reported parasitizing a caterpillar of Sphinx poecila Stephens (Sphingidae) which was collected feeding on Spiraea alba Du Roi (Rosaceae), a species of white meadowsweet native to the wet soils of the Allegheny Mountains and other portions of eastern North America. Here, we report and describe this new host-parasitoid-food plant association in southern New Hampshire, and include a distribution map for the species. Biological, ecological and phylogenetic analyses, and an identification key for the nine known species of Microplitis that attack sphingids in the New World are provided.

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.
