In the wax cap book we put borealis and virgineus in synonomy. But the final verdict is still not in.

recognizes both Cuphophyllus virgineus and C. borealis, but lists niveus as a synonym for virgineus.

Is there a difference between

borealis and virginea?

Kuo points out that the concept of borealis in North America may not be well defined, as descriptions vary. But Roody’s depiction, under the heading “Hygrocybe borealis” (Mushrooms of West Virginia and the Central Appalachians) is a macro dead ringer for this collection. However, the spores in this collection are more elonagted than Roody reports for borealis (and also max legnth a bit more). Also, spore quotients reported for virginea seem too small to fit this collection. Hesler and Smith report niveus with spore measurments closer to this collection. Phillips reports a long spored form of niveus where the ratio is 2.

Could it be that niveus, virginea, and/or borealis are seperated along the lines of spore dimensions?
