Roots of five species of Calanthe and two species of Phaius from north, midland and south of Taiwan were collected for the isolation of orchid mycorrhizal fungi. Total for 104 isolates of fungi were isolated. They are identified respectively by the traditional method or DNA sequence. Results showed thatTrichoderma and Mucor were most often isolated fungi. The DNA sequence results showed that only Xylaris was most common fungus.

However, the 3 groups from medium A exhibited the highest microbial diversity and best decolorization results with 99.53% and 97.42% color removal rate of Reactive Red M-3BE and Acid Red. From them, 16 strains of fungi were isolated and primarily identified as Saprolegniaceae, Eurotiaceae, Erysiphaceae and Physodermataceae . Fungi groups from medium B and D exhibited a bit lower color removal rate of various dyes and only 3 and 2 isolates primarily classified as Saccharomycetaceae and Eurotiaceae were obtained from them. Fungi cultures in medium A and B could produce lignin peroxidase, and those in medium D could be detected higher activity of laccase. All the fungal cultures exhibited very weak activity of manganese dependant peroxidase.

Results showed that, pyrolin had obvious action on two species of fungi, and the antifungal effect was positively correlative with concentration. The EC50 was 0.4076 mg/mL and 0.4626 mg/mL respectively after cultured 3 days. The main antifungal period was the fast growth period of fungi, and lead to it lag behind. Observation under SEM revealed that pyrolin caused a series of marked morphological and structural alterations of hyphal. These changes included mutual adhesion of mycelium, the hyphal was irregular in diameter, local denting, some of mycelium was broken, disruption of cell wall, outbreaking of inner cytoplast, and the empty cavity appeared. As a result, pyrolin restrained the growth of these fungi.

结果表明，鹿蹄草素对上述两种真菌均具有明显的抑制作用，抑菌效果与浓度呈正相关，培养3d时的EC50分别为0.4076、0.4626 mg/mL；抑菌时期主要是在真菌的快速生长期，使其快速生长期滞后；扫描电镜显示，鹿蹄草素作用下菌体形态发生异常变化，表现为菌丝体之间相互粘连，菌丝粗细不均匀，细胞壁破裂，局部凹陷，部分菌丝断裂，大量内容物外溢，出现空腔等现象，从而发挥其抑菌作用。

The universal primers of ITS1 and ITS4 for fungi were used in amplification of genomic rDNA sequences. A target fragment was obtained by ITS-PCR. Then, the fragment is cloned into the vector of pMD18-T before sequencing. The result of sequencing showed that the fragment is 692 bp in length. The results of Blast in Genbank and the analysis of fungal rDNA systemic development show that the relation between this fragment to the fungi of Sporisorium is closest, while the relation between it to the fungi of Ustilago is much far. It suggests that the name of Ustilago scitaminea for sugarcane smut isn't consistent to the result of rDNA systemic development analysis. It still needs more experiments to support this hypothesis.

用真菌rDNA序列分析的通用引物ITS1和ITS4，通过ITS-PCR得到目的片段，克隆在pMD18-T载体上后进行测序，结果显示该片段的长度为692 bp，与Genebank中已报道的真菌序列进行Blast和系统发育树分析，表明所获得的序列与Sporisorium属真菌具有更高的亲缘关系，而与Ustilago属真菌的亲缘关系较远，这与一直沿用的甘蔗黑穗病菌的命名似乎并不吻合，有待进行更多的研究以证实。

Ninety seven spores or sporocarps of VAMF were wet sieved from the rhizosphere soil of mycorrhized pteridophytes, from which 25 VAMF species which belonged to the genera of Acaulospora, Gigaspora, Glomus, Sclerocystis and Scutellospora respectively were identified, and the taxonomic characters of the 25 species were described. The Glomus fungi were the dominant VAMF in the rhizosphere soil of pteridophytes, they took up 44% in the identified 25 VAMF (11 species belong to Glomus); the fungi in Acaulospora and Sclerocystis in the next place, they took up 24% and 16% respectively in the identified VAMF; the fungi in the other genera took up 16%. In terms of the relationships of pteridophytes and the VAMF isolated from their rhizosphere soil, there was no specifity between the VAMF and their host.
