HERVERT V., MARVANOVÁ L., KAZDA V. (1980): Alternaria pluriseptata on cucumbers and remarks to its classification. Česká Mykologie 34(1): 13-20 (published: 1980)
abstract
During a study of cucumber pathogens in Bohemia, Alternaria pluriseptata (Karst. et Har.) Jørstad was isolated from leaf spots of cucumbers. Since 1972, the fungus has been regularly recorded in cucumber-growing areas such as Všetaty, Mělník and Prague. Isolates were cultured on carrot agar and tested on three cucumber cultivars: Nejlepší ze všech, Znojemské nakládačky, and Spotresisting. Infections were successful. The fungus is problematic to classify. On host plants, it produces typical Alternaria conidia, but cultures produce spherical conidia resembling the genus Ulocladium. Virulence decreased with prolonged cultivation.

abstract
Five species of the section Lactiferae (Heim 1931) with a strong aromatic fruit smell reminiscent of rotting pears or of jasmine and hyacinth blossoms are thoroughly described from fresh material gathered by the authors or obtained from others. These are: Inocybe pyriodora (Pers. ex Fr.) Kummer, I. incarnata Bresadola, I. erinaceomorpha Stangl et Veselský sp. nov., I. corydalina Quélet, and I. tricolor Kühner. The authors have examined the original descriptions and attempted to resolve some nomenclatural problems.
HERVERT V. (1977): Academician Ctibor Blattný octogenarian. Česká Mykologie 31(4): 223-224 (published: 1977)
abstract
Academician Ctibor Blattný, one of the founders of Czechoslovak phytopathology, long-time vice-chairman and honorary member of the Czechoslovak Scientific Society for Mycology, celebrated his 80th birthday on September 8, 1977. His biography and scientific, popularization and pedagogical activities were previously evaluated in this journal by A. Pilát. His extensive publication activity is evidenced by selections of works published by the author of this article on the occasion of his 70th and 75th birthdays. Blattný made significant contributions to various areas of agricultural research and especially to plant protection. He conducted pioneering work on hop diseases, notably Pseudoperonospora humuli, and published a major monograph in 1926. He remained devoted to hops, contributing to forecasting diseases and pests, and emphasized the importance of negative selection for removing diseased plants. His discovery in 1942 of a new biotype of Synchytrium endobioticum, the cause of potato wart disease, was of global significance and confirmed later abroad.
ČERNÝ A., LUDVÍK J., HERVERT V., BLATTNÝ C.SR. (1977): Vielfarbige Verkümmerung der Fichte und Zusammenhang dieser Erkrankung mit dem massenhaften Auftreten des Hallimasches in der Ostslowakei. Česká Mykologie 31(3): 126-131 (published: 1977)
abstract
The multicoloured dwarfing disease of spruce has been observed and studied since 1950 on Norway spruce (Picea excelsa Link) in Eastern Slovakia, in the region of the Poprad and Dunajec rivers. The mass dying of trees was primarily attributed to honey fungus [Armillariella mellea (Vahl ex Fr.) P. Karst.]. The authors present consistent differences between the common infection of spruce by this fungus and the “multicoloured dwarfing disease of spruce.” Their hypothesis that this is a viral disease was confirmed electron-microscopically by detecting isometric particles in the needles of diseased spruces. Armillariella mellea probably acts as a vector in this process and contributes to the faster death of infected trees. The transmission of the multicoloured dwarfing disease of spruce was successfully achieved by grafting using bark shields.
BLATTNÝ C.SR., KRÁLÍK O., RAJTR L., HERVERT V. (1977): Virose dystopische vielfältig mikrokarpophorische Proliferation des Pilzes Flammulina velutipes (Curt. ex Fr.)Sing. und Bemerkungen zu den Virosen der höheren Pilze. Česká Mykologie 31(2): 57-59 (published: 6th May, 1977)
abstract
The occurrence of microcarpophoric fruitbodies on thickened stipes of Flammulina velutipes (Curt. ex Fr.) Sing. is described. These neoformations on the host organism are considered by the authors to be a result of a virotic disease. This is documented by the presence of rod-shaped and spherical particles in the tissue of the fruitbodies. In the second part of the paper, several viral diseases of higher fungi and the possibility of classifying viruses as organismoids are discussed.
