Phanerochaete globosum Lin et Chen, Taiwania 35: 100. 1990.

 Description: Macroscopic characters: Basidiocarps resupinate, widely effused, adnate, forming irregular orbicular areas, with small islands, 250–400 μm thick, 1–3 × 3.5–5 cm, membranaceous or ceraceous, cracked, even, smooth, pallid, white to ivory yellow, not changing color in 5% KOH; margins thining out, pruinose, white. Microscopic characters: Basal layer of context 50–60 μm thick, composed of densely interwoven distinct hyphae; intermediate layer of context 150–325 μm thick, composed of longitudinally interwoven distinct hyphae; hyphae 3–4 μm wide, thin-walled, smooth, with large clamp connections; renewed or young hyphae protruding, 37.5 μm high, 2–2.2 μm wide, with clamp connections; hymenial layer 25–37 μm thick, densely crowded in palisade; basidia subclavate, 4 μm wide, with 4 basidiospores; paraphyses slightly ventricose, or capitate, 4–6 × 16–20 μm; sterigmata 0.5 μm wide at base, 5 μm long; basidiospores globose, subglobose or pyriform, strongly apiculate or rostrate, 4 × 5–6 μm, smooth, thin-walled, non-amyloid.

 Note: This new taxa is characterized by its absence of cystidia, presence of ventricose or capitate paraphyses and strongly apiculate globose basidiospores. It is very closely allied to Corticium fallax in shape of spores, but the context of the latter is characterized by masses of mucilage in context and by stratification of context, while that of this species is neither obscure nor stratification in context.
