Note 37 — THE NORTH AMERICAN SLIME-MOULDS (continued 4)

In the Mycetozoa, 2nd ed., p. 158, is cited Stemonitis virginiensis Rex as a synonym of this variety. By reference to p. 163 of the present volume the Virginian stemonitis is left as Rex assigned it, and if the present variety be synonymous, it should be quoted there. The treatment of the species C. nigra in the second edition does not establish such fact, nor with three varieties make for any increasing clearness.
