Two new species of Ceriporia (Irpicaceae, Basidiomycota) from the Asia Pacific area

Two new species of Ceriporia , including C. eucalypti sp. nov. and C. sino-viridans sp. nov., are described based on the morphology and phylogeny of samples from the Asia Pacific region. C. eucalypti is characterized by resupinate and snow white basidiocarps when fresh, abundant crystals and oily substances present in the subiculum and trama, distinct allantoid basidiospores that measure 4–4.4 × 1.1–1.4 µm, and growth on wood of Eucalyptus in Australia. C. sino-viridans is characterized by white to flesh-pink pores when fresh, distinctly curved to lunate basidiospores that measure 3–3.5 × 1.7–2.2 µm. It occurs in tropical China. C. eucalypti , C. sino-viridans , C. aurantiocarnescens, and C. viridans are phylogenetically related, but they can be distinguished by the size of their basidiospores. A key to the accepted species of Ceriporia that are accepted in the Asia-West Pacific area is provided.
