Splitting them seems weak at this time.

Light & Woehrel separated Sparassis radicata from S. crispa on the bases of DNA sequence analyses, reproductive and morphological criteria, yet they give no evidence of any of these. The microcharacters seems identical in their article, the macrocharacter in their key that separates them is a branched stalk for S. crispa and an unbranched stalk for S. radicata. No photos were provided of this feature. Sadly, no indication was given on the number of gene segments analysed. In the 1970’s Gilbertson found that the hyphae from European S. crispa and the Western US S. radicata could combine and synonymized them. Literature cited indicates three loci analysis is the bases of the DNA evidence, but no data is given. This article fails to give a solid reason to separate them at this time.
