The Taxonomic Study on the Genus Amanita in Korea
Kim, Yang-Sop ;
The Korean Journal of Mycology, volume 4, issue 1, 1976, Pages 1~10
For the purpose of investigating the distribution and flora of wild mushrooms in Korea, this study was conducted primarily on the genus Amanita. Through survey of Suweon, Kwangneung, Mt. Chiri, Taegwanryung, Yeongdong district and Mt. Hanta, 25 species of Amanita including 3 unrecorded species were discovered and are described in this paper. The author proposes to group 25 Korean species of Amanita into 3 subgenera according to morphological characteristics by the modern taxonomic system, and also designated the 3 unrecorded species of Amanita including one variety in Korean common name.

40 specimens of higher fungi were collected at the bamboo forest of Damyang, Jyunranam-Do, and Kyungju, Kyungsangnam-Do during May 6, August 17, 29 and October 29, 1976. These fungi were identified. They were composed of 3 orders, 10 families, 19 geaera and 23 species. Among them, Clitocybe catancifloccosa S. Ito et Imal, Collybia matris S. Ito et Imal, Mcrasiellus lactea (Pers. ex Fr.), Lepiota hetieri Boud. and Paxillus atrotomentosus (Fr.) Fr. var. bambusinus Baker et Dale were found to be new in Korea.

Among the higher fungi which wore collected in the Geong Gi Province and Seoul Korea, nine species, i.e., Mycena haematopoda, Amanita griseofarinosa, Pholiota spectabilis. Pholiota vermiflua, Boletus erythroporus, Russula alutacea, Russula chameleontina, Russula xcampelina and Polyporus sulphureus, were found to be unrecorded species in Korea. The morphological, histological and microchemical characteristics of these fungi were reported.

The carpophores of Daedaleopsis tricolor(Fr.) Bond. et Sing. which grows wildly in Korea were collected in the Gyeong Gi Province and extracted with chloroform and methanol. Four compounds were isolated from the extracted and two of these compounds were identified as ergosterol and stigmasterol by T.L.C., G.L.C. and chemical tests.
Influence of Nutritional Supplementation to the Substrate on Vegetative and Reproductive Growth of Winter Mushroom, Flammulina velutipes (Curt. ex Fr.) Sing. and Chemical Changes of the substrates Produced during Growth of the Fungus
Chang, Hak-Gil ;
The Korean Journal of Mycology, volume 4, issue 1, 1976, Pages 31~44
The studies were carried out to examine the effects of supplementation of nutritional substances and physical conditions in substrate on the mycelial growth and yield of fresh sporophores of winter mushroom, Flammulina velutipes(Curt. ex Fr.) Sing. and to obtain further informations on the nutritional requirements of the fungus with reference to improvement of substrate through [analysis of chemical composition of the substrates during the cultivation period. The results obtained are summarized as follows: 1. The best yield of fresh sporophores, 84.4 g per 280 g substrate in a bottle, was obtained from the mixture of poplar sawdust 10 and rice bran 3 by volume when Flammulina velutipes was cultivated on the poplar sawdust supplemented by rice bran, wheat bran, cattle manure and various combinations of these materials as nutrient sources. The substrates of poplar sawdust 10 plus rice bran 3 and 2 or wheat bran 3 with a higher yield of fresh sporophores showed a comparatively higher content of total nitrogen. total sugar, and potassium. 2. The mycelial growth of the fungus was compared on the substrates of poplar sawdust supplemented by the several nutrient sources and poplar sawdust alone. The fastest linear growth occurred on substrates of poplar sawdust alone and poplar sawdust plus cattle manure deficient in sugar and nitrogen sources, but mycelial density was more sparse on the substrates. Also, growth in a solution extracted from these substrates was very meager. 3. In the substrates which varied with bulk density and moisture content optimum bulk density and moisture content for mycelial growth was 0.2g/cc and 72% on a dry weight basis, respectively, but the highest yield of fresh sporophores was obtained at the bulk density of 0.3g/cc and moisture content of 67%. 4. By increasing the ratio of rice bran in poplar sawdust the loss of total weight and ash, content at each stage was increased, and during the cultivation period of 75 days, loss of total weight of the substrates at inoculation was 17.8 to 28.8% and ash content increased about 12%. 5. 11 to 14% of the cellulose and 3 to 4% of the lignin content per original substrate were decreased without a great difference depending of the mixing ratio of rice bran. The soluble glucose concentration in the substrates was increased during the same period. 6. In the process of vegetative and reproductive growth of the fungus upon the substrates, the total nitrogen was increased in quantity per dry weight of sample but was reduced in absolute quantity to a minute extent. There is no great changes in content of organic nitrogen including amino acid nitrogen, and hydrolysable ammonium nitrogen during the vegetative growth period, but occurrence of sporophores resulted in a decrease in the nitrogen content of these forms. On the one hand, by an increase of additive amounts of rice bran, nitrogen contents of these forms were higher and the reduction range during the reproductive growth period became wider. 7. Mycelial growth of the fungus was accelerated in various liquid media supplemented with organic nitrogen sources such as peptone and yeast extract in comparison with addition of inorganic nitrogen sources. Furthermore, mycelial growth was mere vigorous in the media with higher content of organic nitrogen sources.

In the studying of Mycoparasitism both the Host and Parasite were identified and the course of growth were investigated. Its pathological histology and anatomical structure under the optic and electron microscope arc reported in this paper. The reciprocal relationships between these organisms are summarized as follows; 1. Strains of Host and Parasite were identical with Aspergillus niger and Penicillium rugulosum respectively. 2. The Parasite was proved to parasitize on the sterigmata of host. 3. In the process of parasitism, cytological contents of host were getting lost. 4. Growing on Synthetic medium, the parasite proved to the nonobligate.

This study was undertaken to investigate the direct effect of three different kinds of steroid to Trichophyton(T.) mentagrophytes growth in vitro. A loopful of T. mentagrophytes was inoculated into Sabouraud's media and Sabouraud's media containing various concentrations of dexamethasone (0.04%-0.00004%) prednisolone (0.25%-0.00025%), triamcinolone acetonide (0.2%-0.0002%), Sabouraud's media containing imidazole nitrate (econasole nitrate) 10 micro gm. per cc. of media, and Sabouraud's media containing econazole nitrate
per cc. of media of various dexamethasone concentrations (0.04%-0.00004%). After inoculation they were left for two weeks at room temparature and the colony diameter were compared between Sabouraud's media and Sabouraud's media containing various concentrations, of three different steroids, Sabouraud's media containing econazole nitrate and Sabouraud's media containing econazole nitrate of various dexamethasone concentrations. For complementary study, hanging slide culture were done between Sabouraud's media and Sabouraud's media containing various dexamethasone concentrations to compare the degree of branching of hyphae and sporulation serially. The study results were as follows: 1. There is no significant difference in growth rate of T. mentcgrophytes between Sabouraud's media and Sabouraud's media containing various concentrations of three different steroids. 2. There is no significant difference in growth rate of T. metagrophytes between Sabouraud's media containing econazole nitrate 10 micro gm per cc. of media and Sabouraud's media containing econazole nitrate 10 micro gm per cc. of media of various dexamethasone concentrations. 3. In hanging slide culture, there is no significant difference in branching of hyphae and sporulation between Sabouraud's media and Sabouraud's media containing various dexamethasone concentrations.
