Fomitiporia rhamnoides sp nov (Hymenochaetales, Basidiomycota), a new polypore growing on Hippophae from China

Based on morphology and phylogenetic analysis, Fomitiporia rhamnoides sp. nov. is described. It is characterised by perennial, pileate basidiomata, distinctly shining poroid surface, a zonate context, 11-13 pores per mm, parallel tramal hyphae and regularly arranged contextual hyphae, the presence of cystidioles, globose, hyaline, thick-walled, smooth, dextrinoid, strongly cyanophilous basidiospores measuring 5.8-7 x 5.4-6.5 pm and growing on Hippophae rhamnoides in northern China. Fomitiporia rhamnoides differs from other Fomitiporia species growing on Hippophae by its smaller pores (11-13 per mm vs. <10 per mm).
