The wood decay fungi Antrodia P. Karst. play important ecological roles and have significant industrial and economic impacts as both wood degraders and sources of pharmaceutical and biotechnological ...products. Although each Antrodia species has distinct morphological characteristics, the misidentification rate is especially high due to their simple morphological characters. A combination of morphological and internal transcribed spacer region sequence analyses revealed that 27 of 89 specimens previously identified by morphology alone were correct, whereas 35 of these specimens were misidentified as other Antrodia species. We report here that seven Antrodia species exist in Korea (A. albida, A. heteromorpha, A. malicola, A. serialis, A. sinuosa, A. sitchensis, and A. xantha) and based on these specimens, we provide taxonomic descriptions of these species, except for A. serialis, which was only confirmed by isolate.
Lenzitopsis oxycedri is reported from the Balkan Peninsula for the first time, growing in a Mediterranean juniper forest in the Republic of Macedonia. This very rare species was collected on living ...branches of Juniperus foetidissima from Galichica National Park, in the
southwestern part of the country.

The effects of Trichoderma spp. on wood degradation were examined using five basidiomycetes, i.e., Fomitopsis palustris, Trametes versicolor, and three wild strains. To measure block mass losses, ...blocks of Japanese white birch (Betula platyphylla var. japonica) were covered with four Trichoderma spp. strains immobilized on heat-treated (240−280℃) wood particles and exposed to the basidiomycetes at 25℃ for 8−12 weeks. Each strain caused inhibition of wood degradation. ANCT-05013 provided the strongest inhibition, although inhibition was lost by heat sterilization. Mass losses without the immobilized Trichoderma spp. were 20−87%, but were only 16% and 2−3% with ANCT-05013 after exposure to T. versicolor and the other basidiomycetes, respectively.
This work focus on comparison of biological degradation of wood caused by wood-decay fungi (white and brown rot). Test samples were made of European Beech Fagus sylvatica (L.). As wood-decay fungi ...were used Trametes versicolor (L.) Lloyd (white rot) and Serpula lacrymans (Wulf. Ex Fr.) Schroet (brown rot). Aim of this work was comparison of rate of propagation of wood-decay fungus and degradation of wood in time. After termination of the test was made comparison of intensity of degradation between both fungi species. Weights of test samples were diminishing for both groups of wood-decay fungi during three months. Moisture content increased in direct proportion with time. Compression strength in direction of wood fibers of tested samples was diminishing. Samples tested by Serpula lacrymans had the fastest decrease of compression strength after first and second week of degradation. Samples tested by Trametes versicolor had different course. Compression strength significantly decreased after first month and third month of degradation. On the other hand module of elasticity of both tested groups was diminishing already during first and second week of degradation. Generally, it is possible to say that Trametes versicolor has more significant impact on changes of mechanical characteristic of wood, because it causes degradation of all chemical constituents of wood.
Phellinus sulphurascens Pilát Türkiye'de Akdeniz bölgesinin iki farklı lokalitesinde, ardıç ağaçları kütüğü üzerinde (Juniperus
excelsa ve J. foetidissima) toplandı. Bu nadir mantar Avrupa'da ...yalnızca Rusya Ural Dağlarından bilinmektedir. Bu mantar Kuzey
Amerika'da Douglas köknarı ve diğer koniferlerde saldırgan kök çürüklüğü hastalığıdır. Bu mevcut yayılış alanı dışında ve ardıç için
konak olarak yeni bir bulgudur.
Phellinus sulphurascens Pilát was collected from juniper tree stumps (Juniperus excelsa and J. foetidissima) in two
different localities situated in the Mediterranean region of Turkey. This very rare species is known in Europe only from the Ural
Mountains in Russia. This fungus is an aggressive root rot pathogen associated with Douglas fir and other conifers in North America.
This is the first report on juniper as a new host outside of its known distribution area.

The purpose of this study was to develop soil conditioner using wood decay fungus. The effect of soil conditioner treated with SJ-28 fungus was tested by lettuce cultivation. Cultivating efficiency ...was investigated by the yield of lettuce. In the plot of soil conditioner treated with SJ-28 fungus (FPG) showed weight of lettuce leaves 4425 g of total yield which was greater than 2434 g shown in the control. Also the numbers of actinomyces and fungi were increased in the plot of soil conditioner treated with SJ-28 fungus (FPG), beneficial for soil. The number of bacteria showed decrease in FPG plot. FPG showed possibility as a soil conditioner. 본 연구는 목재부후균을 이용한 토양개량제를 개발하고자 리그닌 분해 우수균으로 선발된 SJ-28 균주의 처리가 상추재배에 미치는 효과를 조사하여 비교하였다. 시판 유기질퇴비에 균처리를 실시하여 상추를 재배하였다. Control 구에서의 총 중량이 약 2434 g인데 비해 균처리 토양개량제 처리구(FPG)에서는 총 중량이 약 4425 g으로 가장 높게 나타났다. 또한 FPG 처리구에서 토양에 유익한 방선균의 수가 많은 증가를 보였고 사상균의 수도 증가하였다. 반면 유익하지 않은 세균의 수도 FPG 처리구에서 가장 많은 감소를 나타내었다. 선발균 SJ-28 처리구에서 효과가 우수하게 나타나 토양개량제로서의 가능성을 보여 주었다.
