CuxxIiNGHAM.— The Uredinales, or Rust-fungi, of New Zealand. 667 
Spores obovate or elliptical, 26-30 x 19-25 mmm. ; epispore moderately 
and somewhat coarsely echinulate, З mmm. thick, hyaline, cell-contents 
tinted yellow, with 2-4 indistinct scattered germ-pores on one face. 
III. Teleutosori hypophyllous, minute, lenticular, dark chocolate-brown, 
21-26 mmm.; apex rounded, slightly (4 mmm.) thickened, base attenuate, 
frequently rounded, basal cell slightly narrower than the upper ; slightly 
brown, cell-contents granular, nuclei conspicuous; pedicel persistent, 
hyaline, fragile, up to 50 x 5mmm.; germ-pore of the upper cell apical, 
conspieuous, basal pore one-half to two-thirds below septum, conspicuous, 
both occasionally papillate.

The host is endemic, and occurs in both Islands (Cheeseman, 1906, 
p.222). The aecidia are conspicuous and numerous; the uredo- and teleuto- 
ecidium Anisotomes Reich., recorded as occurring on Anisotome geni- . 
culata Hook. f. (= Angelica Gingidium), may belong to this species, but 
the description given does not agree with the above. E 
This species, although it shows a general resemblance to Puccimia 
Angelicae Fol., differs from the latter species in the uredospores not being. 
thickened at the apex, in the presence of aecidia, and in minor differences 
in the teleutospores and sori. i 
Characterized by the smooth epispore, and slightly or not thickened apex 
of the teleutospore.
