(Corner (1970) included four taxa with white fruit bodies and broad spores in subg. Holocoryne. None is 2-sterigmate, and I can find no other report of such a fungus in the literature on Pacific taxa. This and Clavaria subsordida were placed under a single taxonomic designation based on fruit body morphology, for they are extremely similar macroscopically. Closer examination revealed that C. ypsilonidia produced ellipsoid spores and strictly 2-spored basidia, immediately separating it from C. subsordida. Also, both taxa are similar in fruit body color and stature to C. echino-olivacea, which produces spiny spores. Care must be taken to distinguish these three taxa. Basidia in Clavaria ypsilonidia are short (not more than 50 µm long by hymenial measurements) and somewhat agglutinated, obscuring the basal loop-like clamp. The basidia of C. subsordida are virtually free (not agglutinated) and the clamp-or bifurcate basidial base - is easily observed. Fruit bodies of the species vary in color from virtually pure white (which I originally designated a separate species) to pallid olive-buff, sometimes with the club pigmented but not the stipe. This color variation appears irregular, however, and unaccompanied by micromorphological variation, so I consider that no separate taxa are warranted.)
