The aims of this study were to investigate various components and their physiological activities of Sarcodon aspratus (Berk.) S. Ito which grows wildly in Korea, belonging to the family Thelephoraceae. The analysis of the powered carpophore of this fungus by TLC and an amino acid autoanalyzer revealed that it contained twenty-one free amino acids and that twenty­two total amino acids were identified in its acid hydrolysate. These amino acids were also quantified.

To determine contents of inorganic elements of Ganoderma lucidum, the horn-shaped carpophores and the pileus of Ganoderma lucidum were incinerated and analyzed by inductively coupled plasma atomic emission spectrophotometry. The ash contents of the pileus and the horn-shaped carpophore were 1.48% and 1.40%, respectively. The pileus contained calcium, magnesium, sodium, manganese, iron, zinc and germanium in that order. The horn-shaped carpophore contained magnesium, calcium, zinc, manganese, iron, copper and germanium in that order. To examine the protein-bound polysaccharide from Ganoderma lucidum for immunopotentiating activity, its fruit bodies were extracted with hot water. Purification of the extract was carried out by acetone precipitation and dialysis. The fraction obtained during the purification procedure consisted of a polysaccharide moiety (51%) and a protein moiety (5%). When the compound was administered intraperitoneally to the mice at a dose of 50mg/kg, it enhanced the accumulation of the peritoneal exudate cells, macrophage and polymorphonuclear leucocytes, thereby indicating immunopotentiation.

The dried carpophores of Sarcodon aspratus were examined for mineral elements and a protein-polysacccharide. Calcium, iron, zinc, magnesium, manganese, copper, lead, cadmium and mercury were detected in that order of contents by atomic absorption spectrometry and automatic mercury analysis. The protein-polysaccharide fraction extracted from the carpophore was found to contain 31.5% protein and 52.8% polysaccharide. The fraction showed no antitumor activity against sarcoma 180 implanted in mice.

Development of efficient substrate formulas to improve yield and shorten production time is one of the prerequisites for commercial cultivation of edible mushrooms. In this study, fifteen substrate formulas consisting of varying ratios of palm press fibre (PPF), mahogany sawdust (MS), Gmelina sawdust, wheat bran (WB), and fixed proportions of 1% calcium carbonate ($CaCO_3$) and 1% sucrose were assessed for efficient Lentinus squarrosulus production. Proximate compositions of mushrooms produced on the different substrate formulas were also analysed and compared. Substrate formulations containing 85% PPF, 13% WB, 1% $CaCO_3$, and 1% sucrose were found to produce the highest carpophore yield, biological efficiency and size (206.5 g/kg, 61.96%, and 7.26 g, respectively). Days to production (first harvest) tended to increase with an increase in the amount of WB in the substrate formulas, except for PPF based formulas. The addition of WB in amounts equivalent to 8~18% in substrate formulas containing 80~90% PPF resulted in a decrease in the time to first harvest by an average of 17.7 days compared to 80~90% MS with similar treatment. Nutritional content of mushrooms was affected by the different substrate formulas. Protein content was high for mushrooms produced on formulas containing PPF as the basal substrate. Thus, formulas comprising PPF, WB, $CaCO_3$, and sucrose at 85% : 13% : 1% : 1%) respectively could be explored as starter basal ingredients for efficient large scale production of L. squarrosulus.

Attempts were made to investigate on the fatty acids of Agaricus bisporus, a cultivated edible mushroom. Fats were extracted from it and saponified with alcoholic potassium hydroxide. Isolated fatty acids were methylated and were subjected to column chromatography and G.L.C. Eleven saturated fatty acids, i.e., dodecanoic, tridecanoic, tetradecanoic, pentadecanoic, hexadecanoic, heptadecanoic, octadecanoic, eicosenoic, uncosenoic, docosenoic, and tricosenoic acids, were identified. Especially palmitic and stearic acids were abundant. Nine unsaturated fatty acids appear to exist in the carpophore.

Attempts were made to investigate the sterol components of Coriolus versicolor (Fr.) Quel, which is one of medicinal fungi and which grows wildly in Korea.Its carpophores were collected in the Gyeong Gi Province and extracted with chloroform and methanol. Four Compounds were isolated and one of these compounds was identified as ergosterol by T.L.C., G.L.C. and chemical tests. ${\beta}-Sitosterol$ appears to exist also in the carpophore.

In order to isolate constituents of Lactarius piperatus$(F_{R.})$ S.F. $G_{RAY}$, the fresh carpophore was homogenized with ethanol in a blendor, stored for three years and subsequently extracted with ethanol. From the concentrated ethanol solution, a mixture of compounds was precipitated, from which a white needle crystal, named 'gultorin', $(mp.160{\sim}162^{\circ})$ was obtained. The physical and chemical characteristics of gultorin were determined.
