This study was conducted to develop optimal solid culture medium for Tricholoma matsutake. As the solid matrix, granitic soil, perlite, vermiculate, pine sawdust and peat moss were compared regarding their effected on mycelial growth. Ergosterol content which is a fungal wall component was used as the growth index of the mycelia. Among the various solid matrixes, the granitic soil, perlite and mixture of the two supported the growth most. Barely flour appeared to be very effective on the stimulating of the mycelial growth when added to the solid matrix. An mixture of the matrix contained an even (1:1:1:1, v/v/v/v) mixture of granitic soil, perlite, vermiculate and pine sawdust. T. matsutake started growth 2 weeks after inoculation and reached stationary growth phase after 8th weeks in the solid matrix mixture. The mycelial density in the solid matrix was 7 times higher than that in fairy-ring soil. In addition, 30~70% water content and 10% humus soil in the solid matrix also supported good growth suggesting that T. matsutake needs humus soil for a nutrient sources. The solid matrix developed in the present study could be used to study physiological characteristics of T. matsutake as well.

The pine mushroom fruit body have a harvest only from natural pine forest instead of artificial culture like other edible mushrooms until now on. We investigated the interrelationship between pine mushroom colonies and insect/invertebrates fauna, and changes of their seasonal populations. Two famous pine mushroom producing district were selected on Bong-wha and Gan-sung Eup, and were surveyed on the ground and in the soil with/without pine mushroom hyphae per month from June to November, 2005. There was some difference in collected Insects and invertebrates between two producing districts. Total number of collected species and individuals were 73 and 22, and 63 individuals with 19 species in Bon-wha and Gan-sung area, respectively. Otherwise, there were many mites and nematodes were living in soil with mushroom hyphae. The population densities of mites were Increased to November from June, however, the population of nematodes were fluctuated with low in hot weather and high in cool.

'Cham', a new cultivar of Agrocybe aegerita, was bred by crossing between monokaryotic strains isolated from GMAG45021 and 'Beodeulsongi1ho' in Mushroom Research Station, Gyonggi Province A.R.E.S. in 2007. The optimum temperature for the mycelial growth of 'Cham' was 26 to $28^{\circ}C$ on PDA medium, whereas that of 'Beodeulsongi1ho'(control) was 24 to $26^{\circ}C$. The optimum temperature for the primordial formation and fruiting body development of 'Cham', as well as 'Beodeulsongi1ho', was 18 to $20^{\circ}C$. In the bottle cultivation, the spawn run period of 'Cham' at 22 to $23^{\circ}C$ was around 38 days and the period from scratching of inoculum to harvest was 12 days. These characteristics of 'Cham' were not different from those of 'Beodeulsongi1ho'. However, 'Cham' had more dark brown-colored, and thicker and stronger pileus, and longer and thicker stipe compared to that of 'Beodeulsongilho'. Freshness of 'Cham' was maintained for 10 days at the storage temperature of $4^{\circ}C$, while that of 'Beodeulsongi1ho' was maintained for 8 days. Moreover, the yield of fruiting bodies of 'Cham' was $141g/850m{\ell}$ bottle, which was similar to that of 'Beodeulsongi1ho'. Both 'Cham' and 'Beodeulsongilho' have lower resistivity against Trichoderma virens and Trichoderma harzianum.

Correlation between Songyi(Tricholoma matsutake, pine mushroom, matsutake) production and the annual pine tree growth in Korea was analyzed with 18 years data of the mushroom production in Sangju area and the annual ring-growth of pine trees at Mt Sogni in the area. The two parameters were not significantly related to each other(r=0.408). A possible reason of this low relationship is that September and October climate affected annual Songyi production through mushroom primordial formation, continued growth of the primordia, while May and June climate did the annual tree-ring growth. Songyi production at Mt. Wolak in Chungcheongbukdo peaked while the minimum daily air temperature ranged about $7^{\circ}C$ to $13^{\circ}C$ during the first week of October in 1999. These show that Songyi production variation is not a simple trend depending on the energy the pine trees have accumulated. Rather, controlling soil moisture and air temperature during Songyi fruiting season can be a significant management option for improving the mushroom production.

This study was conducted to understand the relationship between climatic factors and matsutake(Tricholoma matsutake) mushroom production. Data on local annual matsutake production collected from 29 locations from 1984 to 1993 were analyzed for stepwise and multiple regression with local climatic data, such as monthly maximum, minimum, and average air temperature, soil temperature, relative humidity, amount of rainfall, and number of rainy days. Correlation between monthly climatic factors and annual matsutake production was calculated in each location(Case 1), each year(Case 2), and each month(Case 3). In Case 1, number of rainy days and minimum temperature in Sep. showed positive correlation with matsutake production. In Case 2, maximum, minimum, and average temperature in June showed negative correlation with matsutake production. In Case 3, amount of precipitation in Sep. and Oct. number of rainy days in Sep., and minimum temperature in Sep. and Oct. showed positive correlation with matsutake production. In conclusion, amount of rainfall and number of rainy days in Sep. were the most important climatic factors and correlated positively with matsutake production. Below average air temperature in June was also beneficial for matsutake production.

Relationships between pine-mushroom(Tricholoma matsutake) yield and important climatic factors for the yield(such as monthly precipitation, relative humidity, temperature, and radiation percentage) were examined to find out limiting factors for pine-mushroom production and to develop a method for overcoming the factors by analyzing the yield and climate data for 17 years collected from 18 main regions of pine-mushroom production. Although there were variations among the production regions, climatic condition of September was the most significant factor for pine-mushroom yield in general, and the degrees of importance of each climatic factors were different among the production regions. Mean minimum temperature of September was positively correlated with pine-mushroom yield($$r^2{\geq_-}0.41$$) at the 1% level, of which were 9 regions such as Youngduck, Uljin, Samchuck, Bongwha arid so on. In these regions, vegetation control was expected to be effective for pine-mushroom production by allowing much sunlight penetration to the pine stand, which may increase soil temperature and keeping the temperature around the fungal colony in soil. Precipitation during September was positively correlated with pine-mushroom yield($$r^2{\geq_-}0.41$$) at Namwon, Moonkyung and Sangju. Thus, irrigation around fungal colony in dry soil during September would be effective for enhancing mushroom yield at the regions. Pine-mushroom yield of 1994 was quite low, similar to that of 1993, due to serious drought. In this period, we could manifest the possibility of enhancing pine-mushroom yield by irrigation for overcoming drought at Moonkyung and Keochang regions.

This research is to suggest an ecological management methods by classification of biotope type and its mapping for Tricholoma matsutake. The target area was construction site of the East Hongchun - Yangyang Highway (Yangyang section) where massive production of Tricholoma matsutakes is in place. Specifically, the 700 m long range of area around the road route, Yangyang section, which is over a total area of $19,79km^2$. The flow of this research was as follows: first studied were the characteristics of the Yangyang Tricholoma matsutakes; second, reviews on previous studies on Tricholoma matsutakes; third, the formulation of standards and processes of biotope type considering Tricholoma matsutake production; and fourth, mapping of biotope considering the production area of Tricholoma matsutake. In 24.77% of the region, slope angle measured $30{\sim}40^{\circ}C$, which is suitable for Tricholoma matsutake production. Also, 17.44% of the region had southward vegetation structures, and as for the Pinus densiflora; 26.00% had average receipts; the tree ages was $38{\pm}8.34$ years; and the average density of canopy layer was $9.55{\pm}4.89/100m^2$. The soil acidity (pH) values of 5.0 to 5.6(47.96%) > 5.6 to 7.0(42.90%) > 4.0 to 5.0(9.14%) were slightly high for Tricholoma matsutake growth; but 57.10% of the area had a soil pH of 4.0-5.6. The organic horizon (A0 layer) was $3.39{\pm}2.14cm$, and the mean depths were 4-6cm(78.03%) > 0-2cm(18.10%) > 2-4cm(3.87%). Based on the results of previous studies and field researches on the presence of vegetation (the pine dominance ratio), the topographic structure (the terrain characteristics and slopes), the receipt, the soil structure (the soil acidity and the organic layers interposed between the depths), and the vegetation density, six clusters based on the identified types of biotopes are produced in this paper. Area of distribution according to the type of biotope was Tricholoma matsutake of the potential-production (II) biotope (32.86%) > Tricholoma matsutake of the inadequate-production biotope (22.17%) > Tricholoma matsutake of the adequate (II)-production biotope (17.79%) > Tricholoma matsutake of the adequate (I)-production biotope (14.86%) > Tricholoma matsutake of the potential-production (I) biotope (9.77%) > Tricholoma matsutake of the produced biotope (2.55%).
