Three species of Fulvifomes (Basidiomycota, Hymenochaetales) associated with rots on mangrove tree Xylocarpus granatum in Thailand

We describe three new species of Fulvifomes from Thailand, all of which grow on Xylocarpus granatum, a major mangrove tree species in southeastern Asia. Fulvifomes xylocarpicola sp. nov. is characterized by the perennial and sessile basidiocarps, woody context without a distinct crust, pores 4–6/mm, a dimitic hyphal system both in the context and trama, broadly ellipsoid basidiospores measuring 4–5.5 × 3.5–4.5 μm, and occurrence on the stem of X. granatum. Fulvifomes siamensis sp. nov. is characterized by the perennial and sessile basidiocarps, woody context without a crust, pores 7–8/mm, a monomitic hyphal system in the context, subglobose basidiospores measuring 4.5–6 × 4–5 μm, and occurrence on the root or butt of X. granatum. Fulvifomes halophilus sp. nov. is characterized by perennial, sessile basidiocarps, leathery to corky context with a crust near the pileus surface, pores 5–8/mm, a subdimitic hyphal system in the context, subglobose basidiospores measuring 4–5.5 × 3.5–5 μm, and occurrence on the root or butt of X. granatum. Fulvifomes mangrovicus comb. nov. is proposed for Fomes mangrovicus. A key to the worldwide species of Fulvifomes is provided.
