| Description： |
Basidiocarp annual, stipitate, stipe branched from a major base, forming numbers of imbricate, petaloid or flabelliform pilei, up to 4 cm wide and 1 cm thick in individual pileus, upper surface pale olive-buff at first, becoming wood brown to buffy brown when dry, azonate, very finely tomentose to glabrous, smooth, margin thin, curved downwards when dry. Pores angular to elongate, 2-4 per mm, with thin, often lacerate dissepiments, pore surface cream to ivory white. Context ivory white, up to 6 mm thick. Tube layer decurrent on the stipe, up to 4 mm thick, odor pleasant. Hyphal system dimitic; generative hyphae hyaline, thin-walled, with clamps, up to 5 μm wide, skeletal hyphae thick-walled, aseptate, unbranched to infrequently branched, up to 6 μm wide. Basidiospores ovoid to ellipsoid, hyaline, smooth, 6-7 × 4-5 μm, IKI-. | |||

| Note： |
The profusely branched basidiomata with many petaloid pilei characterize the fungus. Polyporus umbellatus Pers:Fr. and Meripilus giganteus (Fr.) P. Karst. share the character of profusely branched basidiomata with G. frondosa. However, P. umbellatus has cylindric basidiospores while M. giganteus has simple-septate generative hyphae. | |||
