Italy, Japan, Kazakhstan, Kirghizia, Latvia, Morocco, Norway, Pakistan, Portugal, Rumania, Russia (Altaïskyi Krai, Irkutskaya Oblast, Kamchatskya Oblast, Karelia, Krasnoyarskyi Krai, Kursk Oblast, Leningrad Oblast, Mari, Murmansk Oblast, Novgorod Oblast, Orenburg Oblast, Primorskyi Krai, Pskov Oblast, Ryazan Oblast, Smolensk Oblast, Stavropolkyi Krai, Tambov Oblast, Tomsk Oblast, Tula Oblast, Vologda Oblast, Voronezh Oblast), Slovakia, Spain, Sweden, Switzerland, UK (England, Scotland, Wales), USA (Alaska, California, Colorado, Idaho, Kansas, Maine, South Dakota, Washington, Wyoming), Ukraine. Altitude records exist up to 3400m (India), 1950m (USA), 1500m (Greece), 1370m (Canada), 1100m (UK), 900m (Finland), 850m (Morocco), 660m (Ireland) and 600m (Ukraine). The distribution of Rhytisma salicinum is predominantly north-temperate to sub-arctic and circum-polar. In addition, the fungus can be encountered at higher altitudes in mediterranean countries as far south as north Africa. In Britain the species occurs predominantly in the north and west, though exceptional records are known. This may also perhaps indicate a preference for a cooler and wetter climate. The fungus is probably very widely distributed, and in some places may be locally abundant. TRANSMISSION: By air-borne ascospores in humid conditions.

Abstract A description is provided for Tryblidiopsis pinastri. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Abies sibirica [fide Kujala, 1950], Larix sibirica [fide Kujala, 1950], Larix sp. (bark), Picea abies (bark, twig), P. engelmannii (twig) P. excelsa [= P. abies] (bark, twig), P. glauca (bark, twig), P. glehnii, P. jezoensis, P. mariana (twig), P. pungens, P. sitchensis (twig), Picea sp. (bark, twig), Pinus cembra [fide Kujala, 1950], P. laricio, P. resinosa, P. sylvestris [doubtful], Pseudotsuga taxifolia[Pseudotsuga menziesii] [= P. menziesii] [fide Kujala, 1950]. Most records are on Picea abies. DISEASE: Tryblidiopsis pinastri is associated with death of twigs of Picea abies and other members of the Pinaceae. Studies on living twigs have not yet identified symptoms to predict which twig will die and bear T. pinastri. No strong seasonality has been detected in death of twigs which subsequently bear T. pinastri, though there may be a slight peak in the autumn. In much of southern Sweden the fungus is so abundant that virtually all dead attached twigs subsequently develop fruitbodies of the fungus. During mild winters conidiomata have been observed releasing conidia between January and April; unopened ascomata are often present in September, sometimes as early as August, but do not open until at least early May of the following year. By mid-July most ascomata are opened and some contain empty asci. Exact opening time seems weather dependent. Cultures from dead bark immediately under fruitbodies of T. pinastri yield colonies of T. pinastri whereas brownish, recently dead, inner bark yields colonies of Pezicula livida (Berk. & Broome) Rehm. Tryblidiopsis pinastri fruits on dead shoots peripheral to a living branch, suggesting that it may inhabit living branches or shoots vegetatively and be able to fruit when the particular plant organ dies: many isolations from healthy inner bark of P. abies have yielded T. pinastri (Barklund & Kowalski, pers. comm.). Tryblidiopsis pinastri may thus be an endophyte. As such large areas of trunk bark are at times covered with fruitbodies of T. pinastri it is easy to assume the fungus is involved in the death of the tree. Evidence is, however, no more than circumstantial. The other fungus which grew mainly in the most recently dead material (Pezicula livida) is also a well-known inhabitant of P. abies (Butin & Kowalski, 1990), and is also not thought to be pathogenic. Smerlis (1973) tested the pathogenicity of both T. pinastri (as T. piceae) and P. livida, and concluded that neither fungus was pathogenic to P. abies. Kujala (1950) suggested that a decreased tree vitality may affect the fungal activity. GEOGRAPHICAL DISTRIBUTION: Austria, Canada (British Columbia, Ontario, Prince Edward Island, Quebec), Czech Republic, Estonia, Finland, France, Germany, Greece, Italy, Japan, Norway, Poland, Russia (Leningrad Oblast, Moscow Oblast, Murmansk Oblast, Perm Oblast, Smolensk Oblast, Tver Oblast), Slovak Republic, Slovenia, Sweden, Switzerland, Ukraine, USA (Alaska, Colorado, Idaho, New Hampshire, Washington). The fungus has not been recorded in the UK despite frequent searches. A record from Portugal probably relates to a species of Tympanis; there may be other records of Tympanis species from western, central and southern Europe under this name. Altitude records exist up to 1700m (France), 950m (Ukraine), 870m (Norway) and ca 550m (Slovenia). TRANSMISSION: By air-borne ascospores in humid conditions.

Abstract A description is provided for Rhytisma andromedae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Andromeda glaucophylla (leaf), A. polifolia (leaf), Kalmia polifolia (stem), Lyonia ligustrina (leaf), Pieris phillyrifolia (leaf). Almost all records are on A. polifolia. DISEASE: Rhytisma andromedae is found on living and dead leaves and, often, twigs. In Scandinavia and Britain, the stroma forms during July, and conidia are produced in July and August (exceptionally September); stromata with immature ascomata are found between March and May of the following year. GEOGRAPHICAL DISTRIBUTION: Austria, Belarus, Canada (Newfoundland, Ontario, Québec, Saskatchewan), Eire, Estonia, Finland, Germany, Latvia, Norway, Poland, Rumania, Russia (Archangelsk Oblast, Kamchatka Oblast, Leningrad Oblast, Novgorod Oblast, Tver Oblast), Sweden, UK (England, Scotland, Wales), Ukraine, USA (Alaska, Georgia, Maine, Virginia). In Norway the fungus has been recorded from as far north as 70° and is known up to altitudes of about 700 m (Eckblad & Torkelsen, 1986). TRANSMISSION: By air-borne ascospores in humid conditions; ascomata contain ascospores have been observed from May to early August.
