Two resupinate basidiomycetes associated with scale insects, Septobasidium humile and Septobasidium petchii, hitherto only known from Java and Sri Lanka are for the first time reported from Taiwan. Both species were collected on leaves of species of Lauraceae in the Fushan Botanical Garden, described and illustrated with drawings and photographs, and their host insects for the first time identified as members of the Diaspididae (Coccoidea). The specificity of Septobasidium species against diaspidid hosts is discussed with respect to the presumptive modes of nutrition of the Diaspididae known from literature.

Peka (local name) is traditionally used as the commercial wine starter and as fermented food, tien-chiu-niang (local language), with alcoholic sweet taste and a fruit flavor in Taiwan. Fourteen samples from traditional markets and wine manufacturers were collected and isolated seventeen predominant filamentous fungi from peka. They were identified based on the morphological characteristics and these strains were as, namely, Amylomyces rouxii, Rhizopus microsporus var. chinensis, Rhizopus microsporus var. rhizopodiformis, Rhizopus oryzae and Mucor indicus. Among them, R. microsporus var. chinensis, R. microsporus var. rhizopodiformis and M. indicus are new to the fungal flora of peka in Taiwan.
Peka(当地名称)传统上用作商业酒的发酵剂和发酵食品，在台湾具有酒精甜味和水果味。从传统市场和酿酒厂收集了14份样品，分离出17种优势丝状真菌。根据形态特征鉴定为:rouylomyces rouxii、microsporus var. chinensis、microsporus var. rhizopodiformis、Rhizopus oryzae和Mucor indicus。其中，中国小孢子粉、根足小孢子粉和indicus是台湾peka真菌区系的新种。

Ganoderma tsugae Murrill are available in the form of mature and baby Ling chih, mycelia and fermentation filtrate. From these four forms, cold water extracts were prepared and their antioxidant properties were studied. Cold water extracts from mature and baby Ling chih and filtrate showed high antioxidant activities as evidenced by low EC50 value (＜0.1mg/mL) whereas that from mycelia showed a EC50 value of 0.34mg/mL. With regard to reducing power, the EC50 value for Ling chih was lower than 1mg/mL, whereas other EC50 values were 3.64–4.30mg/mL. Baby Ling chih was more effective in scavenging ability on 1, 1-diphenyl-2-picrylhydrazyl radicals as evidenced by its low EC50 value of 4.66mg/mL whereas other EC50 values were 10.14-11.72mg/mL. Four forms of G. tsugae were much more effective in scavenging ability on hydroxyl radials as evidenced by low EC50 value (＜0.1mg/mL). Mature and baby Ling chih were more effective in chelating ability on ferrous ions than mycelia and filtrate. From EC50 values obtained, cold water extracts possessed good antioxidant properties, especially antioxidant activity and chelating ability on ferrous ions.

Twenty-one fungal species were screened for capability of removing pyrene and benzo (a) pyrene in culture. Xylaria regalis was found to show the highest activity. An PAHs-degrading enzyme was purified to homogeneity from the culture mycelium of X. regalis. The crude enzyme was subjected to a series of purification procedures, including QAE Sephadex A-25 anion exchange column, hydrophobic interaction phenyl 650M column and Fractogel HW-55 column chromatography, respectively. The enzyme was purified 70.5 fold, giving a 45% yield. The specific activity was 4690U/mg. The molecular mass of the purified PAHsdegrading enzyme estimated by SDS-PAGE was approximately 29kDa. The optimal pH of the purified enzyme was 8.5 and the enzyme was stable between pH 8.0-9.0. The optimal temperature of the enzyme was 30℃ and it's activity was still stable at higher temperatures. The enzyme was found stable within 2h at 100℃ and retained 60% of activity after 8 h incubation.
