BLATTNÝ C. (1978): Poznámky fytopatologa k československé vědecké mykologii ve středních desítkách let 20.století (1940-1977) a výhled do budoucna. Česká Mykologie 32(4): 193-196 (published: 15th November, 1978)
abstract
The author briefly reviews the development of Czechoslovak scientific mycology between 1940 and 1977, emphasizing the significance of both scientific and practical traditions in the field. He mentions notable historical figures such as A. J. Corda and B. Němec and discusses past achievements in taxonomy, diagnostics, and plant protection. He also addresses the need for future developments, especially in response to increasing cases of mushroom poisoning due to the widespread popularity of fungi among the public.

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.

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.
BLATTNÝ C., KRÁLÍK O., VESELSKÝ J., KASALA B., HERZOVÁ H. (1973): Particles resembling virions accompanying the proliferation of Agaric mushrooms. Česká Mykologie 27(1): 1-5 (published: 25th February, 1973)
abstract
Rod-shaped particles, 22–28 × 119 nm in size, and isometric particles, 30 nm in diameter, were electron microscopically detected in fruit bodies of Armillariella mellea, Laccaria laccata, and Inocybe dulcamara bearing hymeniform proliferations. The particles resemble virions. If they are indeed virions, it is not yet clear whether one or two viruses are involved. In the case of virosis, a name for a complex of viruses causing the proliferation of agaric mushrooms might be used. The disease was transmitted to Laccaria amethystina and Pholiota mutabilis by watering with a suspension of homogenized fruit bodies of Armillariella mellea. The proliferation is therefore presumed to be a virus disease.

abstract
With the fruiting bodies of Armillariella mellea, a proliferation of the gills has been observed for several years, always in the same locality, in the valley of Bílý potok at Veveří Bitýška, county Brno, ČSSR. This proliferation occurred usually in the centre of the cap, but also elsewhere on its surface. Diseased fruiting bodies were used for cultivation of mycelium, which was then inoculated into tree stumps. In subsequent years, gill proliferation was observed in Pholiota mutabilis and Laccaria amethystina growing on those stumps, while untreated fruiting bodies remained normal. The authors consider this abnormality to be virus-induced, also comparing it with similar forms in Cantharellus cibarius and Clitocybe nebularis var. alba. They also mention a case of pore proliferation in Trametes gibbosa and proliferation in Clitocybe nebularis var. alba in another locality.

abstract
Armillaria mellea (Vahl ex Fr.) Kummer, a known parasite of many deciduous and coniferous trees, was found parasitizing raspberry (Rubus idaeus L. cv. Lloyd George) in a private garden in Holany, Česká Lípa District, North Bohemia, on June 21, 1969. The report includes a detailed description and notes on the rarity of such occurrence.

abstract
Studies on the virus diseases of Laccaria laccata, L. amethystina and Cantharellus infundibuliformis have been carried out. Further details on the ecology of these diseases and morphology of pathological anomalies have been given. The experimental infection method is also described. Observations using an electron microscope demonstrate that virions with globular virus particles are present in the microcephalic sporophores of Laccaria laccata. Microcephaly has been found in both of the other two fungi. Virion size has been shown to be 28 nm. Further, we have discussed some phenomena of a different type which might be of virus origin, both in the species of fungi studied here and in two other species, Cantharellus cibarius and Armillaria mellea.
BLATTNÝ C. (1966): Hoplothrips pedicularius (Haliday) auf Fruchtkörpern von Stereum purpureum. Česká Mykologie 20(4): 216 (published: 1966)
abstract
In September 1965 in Holany (Česká Lípa district), larvae and a few adult thrips of Hoplothrips pedicularius (Haliday) were found en masse on fruiting bodies of Stereum purpureum (Pers.) Fr., feeding and living especially on the underside. They were also occasionally found on Tricholoma rutilans (Schaeff. ex Fr.) Kummer and Pholiota mutabilis (Schaeff. ex Fr.) Kummer. This represents an ecologically interesting discovery since thrips of this genus were previously known to feed under bark, not on fruiting bodies.
BLATTNÝ C. (1966): Viröse Mikrokefalie bei Laccaria sp. und weiter Pilzarten. Česká Mykologie 20(4): 215 (published: 1966)
abstract
Viral microcephaly, restricted to certain micro-locations, was frequent in 1965 in the Česká Lípa district in Laccaria laccata (Scop. ex Fr.) Cooke. It was also found in South Bohemia in 1958. In 1965, it was also found in Laccaria amethystina (Bull. ex Mérat) Murrill, and in Cantharellus infundibuliformis (Scop.) Fr. in Vlašim district. Observations from 1962 onward show that these fruiting bodies, affected by microcephaly, occur regularly and in increasing areas under favorable conditions.

abstract
This article summarizes the progress of mycology and phytopathology in Czechoslovakia over the past twenty years. It outlines the growth in research institutions, funding, and the number of professionals in the field. The authors emphasize the influence of the political shift after 1945 on the development of science and highlight key personalities and contributions in Czech mycology during this period.
