OBJECTIVE: Studying the fruit-body development of polyporus umbellatus to reveal the life-cycle of this medicinal fungus.

METHODS: Parts of materials treated by paraffin section, and examined under a light microscope; parts of materials by ultrathin section and observation under transmission electron microscope (TEM).

RESULTS: The fruit-body consists of trimitic hyphae, including generative hyphae, skeletal hyphae and binding hyphae. Generative hyphae are characterized by thin walls, dense cytoplasmic contents. Skeletal hyphae are unbranched, thick-walled, and of a narrow lumen. Binding hyphae are much-branched, tending to weave themselves among the other hyphase of flesh. The morphology of basidiospore development was also discussed in this paper.

CONCLUSIONS: The trimitic hyphae are the main component parts in the different developing stages of fruit-body of polyporus umbellatus.
