9. NECIUM Arthur, gen. nov. 
Cycle of development includes telia, which fill epidermal cells, and possibly pycnia. 
Telia indehiscent, forming continuous layers, more or less distinguishable as compound 
sori. Teliospores oblong or prismatic, apparently one-celled ; wall smooth, slightly colored. 
Type species, Necium Farlowit Arthur (on Tsuga canadensis).
