KLÁN J. (1990): Lignin test - its mycotoxicological and chemotaxonomical significance. Česká Mykologie 44(4): 220-224 (published: 26th November, 1990)
abstract
A total of 135 species of Basidiomycetes were analyzed using the lignin test. Though not specific for amanitins or tryptamine derivatives, the test is useful in chemotaxonomic studies of genera Russula, Lyophyllum, Amanita, and Psilocybe.
KOTILOVÁ-KUBIČKOVÁ L., POUZAR Z. (1988): Three types of basidiospores in Amanita. Česká Mykologie 42(2): 65-70 (published: 10th May, 1988)
abstract
The authors report on the observation of three types of basidiospores in several European species of Amanita. These include normal thin-walled smooth basidiospores, thick-walled ones with internal ornamentation (“crassospores”), and thin-walled spores with external amyloid ornamentation (“examylospores”). These types occur irregularly and only in some carpophores. In the course of years we observed in some specimens of various species of Amanita besides normal thin-walled and smooth basidiospores also two other types of basidiospores which do not seem to be mentioned in literature. Normal basidiospores of Amanita are thin-walled, smooth without any ornamentation and either amyloid or inamyloid depending on the species. The two other types are abnormal spores, which are not present in all specimens studied, but could be observed only in some samples — they occur only in a minority of the samples taken.

abstract
To standardize conditions for the study of antibiotic activity in submerged culture of Melanconis flavovirens, the role of type, age, volume and storage period of inoculum was followed. Cultures derived from a submerged inoculum possessed both antifungal and antibacterial activity, while cultures originating from slants predominantly showed antibacterial activity. The age of the submerged inoculum appeared to be more important for potential antibiotic production than the period of storage at 4°C. The minimum volume of inoculum necessary to obtain antibiotically active cultures on submerged fermentation was estimated.
MICKA K., KLÁN J. (1980): Chemical spot tests of macromycetes with benzidine. Česká Mykologie 34(2): 74-81 (published: 1980)
abstract
Macrochemical colour reactions of benzidine were studied mainly with the species of genera Agaricus, Amanita, Lactarius, Russula, and Tricholoma. With the genus Lactarius, differences were found between the reactions of the milk and the context. Oxidation enzymes, which give a blue-green, blue, or black reaction, were detected in many species of the genera Agaricus, Lactarius, and Russula, whereas with Amanita and most species of Tricholoma they were absent. In the case of the genus Russula, only species with a burning taste give a yellow or ochre reaction. The reactions of benzidine are suitable as complementary characteristics for the determination of some mutually similar species.

abstract
A national seminar on enzymological methods in mycology (Brno, June 1975) brought together Czech specialists. Topics included enzymatic lysis, wood-decay enzymes, and keratinolytic activity. The meeting emphasized interdisciplinary potential of fungal enzymology.

ŠEBEK S. (1966): Stachelschuppinger Wulstling - Amanita echinocephala (Vitt.) Quél. - im Mittellbegebiet gefunden. Česká Mykologie 20(4): 237-241 (published: 1966)
abstract
The author reports another finding of the rare thermophilic mushroom Amanita echinocephala (Vitt.) Quél. in the Nymburk area (Central Bohemia). Previously found three times (1939, 1950, 1961), the species is described, compared with similar species, and its nomenclature and new locality are discussed. This record contributes valuable information to the knowledge of the Czech mycoflora.
