0. Spermogones unknown. 
I. Aecidia hypophyllous and caulicolous; on leaves aggregated into

or bluntly acuminate, not or slightly (3 mmm.) thickened, base attenuate, 
lower cell slightly longer and narrower than the upper; constricted at the 
septum; epispore smooth, 1-5-2 mmm. thick, pallid chestnut-brown, cell-

Host: Olearia Cunninghamii Hook. f. On leaves, petioles, and stems.

: This rust closely resembles Puccinia Atkinsonii G. H. Cunn. (on Olearia 
excorticata Buch.), but differs in many minor characters, especially in the 
non-retuse apex, thinner epispore, and smaller size of the teleutospores.
