Hypochnicium pini, a new corticioid basidiomycete in East Asia

A new species, Hypochnicium pini, is described based on morphological and molecular characters. This species was collected in Seoul, Korea, and Hubei, China. It belongs to the H. punctulatum group and has a morphology quite similar to its sister taxon, H. cremicolor. However, the basidiome thickness, cystidial size, and ITS region sequences differentiate H. pini from H. cremicolor. Detailed description and illustration of H. pini are presented and a key to Korean species of Hypochnicium is provided.
