| Summary: | Two new species of Fulvifomes are described from samples collected in America based on morphological characteristic and molecular evidence: F. centroamericanus Y.C. Dai, X.H. Ji & Vlasák, sp. nov. and F. krugiodendri Y.C. Dai, X.H. Ji & Vlasák, sp. nov. The former is characterized by perennial and sessile basidiocarps, a concentrically sulcate and cracked pileal surface, a homogeneous context, small pores (7–9 per mm), a dimitic hyphal system, subglobose, yellowish and thick-walled basidiospores 4.3–5 × 4–4.5 μm. Macroscopically it resembles F. merrillii, which differs in having larger basidiospores (5–6 × 4–5 μm). F. centroamericanus is similar to F. robiniae in sharing applanate basidiocarps and subglobose, yellowish and thick-walled basidiospores 3.9–4.5 × 3.7–4.2 μm, whereas F. robiniae has larger basidiospores (5–6 × 4.5–5 μm). In nuclear large subunit rDNA (nLSU) and internal transcribed spacer (ITS) based phylogenies, the two new species formed two distinct lineages in the Fulvifomes clade.
