Steccherinum cremicolor and S. elongatum are described and illustrated as new species from Taiwan. Steccherinum cremicolor is characterized by strictly resupinate basidiocarps, a fimbriate margin, short spines, generative hyphae dominating in the trama and subiculum, encrusted skeletocystidia, and ellipsoid basidiospores. Steccherinum elongatum has strictly resupinate and membranaceous basidiocarps, bearing fairly long spines, generative hyphae-dominated subiculum, elongated skeletocystidia, and ellipsoid to subglobose basidiospores.
