To determine the cytotoxic activity of natural compounds, chromatographic separation of the hexanesoluble fraction from the fruiting body of Ganoderma lucidum led to the isolation of four steroids and one triterpenoid. They were identified as ergosterol peroxide (1), stella sterol (2), ergosterol (3), 9(11)-dehydroergostrol peroxide (4), and ganodermanontriol (5) based on spectroscopic evidence and physicochemical properties. These compounds were examined for their cytotoxic activity against HL-60, MCF-7, and LLC cancer cell lines. Ganodermanontriol (5) showed cytotoxic activity with IC$_{50}$ values of 24.8 and 22.9 $\mu$g/mL against HL-60 and MCF-7 cancer cell lines, respectively, whereas compounds 1 - 4 were inactive.

To infer phylogenetic relationships between species of Trichaptum (Polyporaceae), RFLP analyses of PCR-amplified DNAs were accomplished. Regions coding for ITSs of nuclear SSU rRNA genes and for mitochondrial SSU rRNA genes from thirteen strains of four Trichaptum species (T. abietinum, T. biforme, T. fusco-violaceum, and T. laricinum) were amplified and digested with eight restriction enzymes. All the fragmentation patterns were characterized and coded as 0/1 for the absence/presence of fragments. A phylogenetic tree based on the combined data sets was constructed using the Dollo parsimony method. While every two strains of T. abietinum, T. biforme, T. fusco-violaceum, and T. laricinum formed an independent group, the other strains of T. abietimum and T. fusco-violaceum made mixed groupings among compared strains. It is inferred that T. abietinum and T. fusco-violaceum have more variations, possibly geographic or physiological ones, than other species in the genus.

Eight strains of Trichaptun (Polyporaceae), two strains from each species of T. abietinum, T. biforme, T. fusco-violaceum, and T. laricinum were examined to see their phylogenetic relationship by digesting mitochondrial DNAs with EcoRV, Hind III, XbaI, and PstI, and then analyzing fragmentation patterns with the methods of Nei and Li. T. abietinum, T. biforme, and T. laricinum developed an independent phylogenetic lineage, respectively, but T. fusco-violaceum FP-133997-sp showed a close relationship with two strains of T. bioforme, and T. fusco-violaceum HHB-4016-sp barely grouped with those of T. laricinum. Based on the results of the RFLP analysis of mtDNA, it is concluded that T. fusco-violaceum is under way to differentiation into two different subgroups.

Sequences of ribosomal internal transcribed spaces (ITS) obtained from two Antrobia species and two related species were compared to investigate intrageneric and intergeneric phylogenetic relationships of Antrodia. The results showed that Antrodia species causing a brown rot in wood did not form a monophyletic clade and were separated into three distinct groups. Antrodia gossypina and A. vaillantii formed a clade having rhizomorphs as a homologous character. Antrodia serialis, A. sinuosa, and A. malicola formed a group together with Daedalea, Fomitopsis, and Postia species with brown rot habit. Antrodia xantha with a trimitic hyphal system and amyloid skeletal hyphae formed another distinct clade form other Antrodia species. The Antrodia species were separated from white rot genera such as Antrodiella, Diplomitoporus, Junghuhnia, and Steccherinum, indicating the phylogenetic importance of the rot type in the classification of the Polyporaceae.

An unrecorded Antrodia species was collected in South Korea and based on morphological characteristics, the species was identified as Antrodia sitchensis. To confirm its affinity within the polypores, the phylogenetic relationships of A. sitchensis and allied species were established using large subunit rDNA sequences.

The wood-rotting fungi of three Korean islands in the Yellow Sea, Soyeonpyung-do (SY), Oeyeon-do (OY), and Gageo-do (GG), were investigated from October 2004 to November 2005. During four sampling trips on each island, a total of 46, 44, and 44 specimens were collected from SY, OY, and GG, respectively. The identified wood-rotting fungi from SY included 29 species of 22 genera and nine families; OY had 31 species of 26 genera and 10 families; and GG had 34 species of 27 genera and 11 families. The majority of the fungi were in the Polyporaceae, which was represented by 23 genera and 30 species. Auricularia polytricha, Daedaleopsis tricolor, Daldinia concentrica, Hymenochaete cinnamomea, Hymenochaete yasudai, Hyphoderma setigerum, Lopharia mirabilis, Schizopora paradoxa, and Trametes versicolor were collected from all three islands.

Many fungi were collected at Mt. Daedun Provincial Park between the periods from March 2001 to October 2002 and they were identified. According to the results, the fungi diversity included 2 division, 3 subdivisions, 5 classes, 4 subclasses, 12 orders, 35 families, 75 genera and 153 species. Among them Ileodictyon is unrecorded genus and Ileodictyon gracile, Mycena flosum-nivium and Tricholoma lascivum are newly to Korea. Dominant family are Tricholomataceae, Russulaceae and Polyporaceae;genus Amanita and species Collybia confluens and Russula emetica In useful fungi and ecological resources, edible fungi included 51 species; culture fungi 10; poisonous fungi 18: medicinal fungi 17: anticancer fungi 22: ectomycorrhizal fungi 26 and wood rotting fungi 51, In geographical distributions of Chonbuk areas, same species are 50 spcies of Jeongup ; 56 of Mt.Manduck : 84 of Mt.Jiri : 28 of Pyonsan national park : 59 of Cheonju arboretum and 51 of Mt,Sunun.

The effect of Ganoderma lucidum (Polyporaceae) extract on initiation and promotion of liver preneoplastic lesions in chemical carcinogenesis were examined in male rats. Male Fisher 344 rats, 8 weeks old, were injected i.p. with diethylnitro-samine(DENA` 200 mg/kg) as an initiator and were fed on diet containing 0.02%-acetaminofluorene (2-AAF) as a promoter for 2 weeks (group 1, 2` 2-4 week) and were fed on basal diet (group 3 and 4). The rats in test groups(group 1 and 3) were fed on diet containing 0.1% of Ganoderma lucidum extract for 6 weeks (2-8 week).
