II. COLEO: ACEAE. 
Teleutosori waxy. Teleutospores compacted laterally into one (seldom 
two) waxy layer, sessile. Basidia internal. Jredosori, when present, naked 
(Coleosporium), or encircled by paraphyses (Ochropsora) ; uredospores catenu- 
late (Coleosporium), or borne singly on pedicels (Ochropsora). Aecidia, when 
present, with a definite peridium ; spores catenulate. 
The contents of the teleutospores at maturity become divided into four 
Diet.; (4) Chrysopsora Lagerh.; and (5) ? Zaghouania Pat. Chrysopsora 
is by Dietel (1900) included in the Pucciniaceae, but the internal basidium 
becomes external. On this account it has been placed in a separate family, 
the Zaghouaniaceae, by Dumee and Maire (Bull. Soc. Myc. Fr., 1902). 
Grove (1913, p. 318) provisionally places it in the Coleosporiaceae.

Heteroecious. Cycle of development includes 0, I, П, IIT. 
0. Spermogones flattened, linear, without ostiolar filaments, dehiscing 
Aecidia erumpent, definite.  Peridia cylindrical, inflated, opening 
by an irregularly torn apical cleft, hyaline. Aecidiospores subglobose or 
elliptical; epispore hyaline, covered with densely-packed deciduous tuber- 
cules ; germ-pores absent. 
II. Uredosori without peridia, erumpent, definite, pulverulent. Uredo- 
spores catenulate, subglobose, elliptical, or obovate ; epispore hyaline, 
verruculose, tubercules somewhat deciduous; germ-pores indistinct. 
III. Teleutosori indehiscent, waxy, flattened, indefinite. Teleutospores 
at first unicellular, becoming 4-celled by transverse septa, sessile ; epispore 
smooth, hyaline, strongly thickened at the apex ; germ-pores indistinct. 
Distribution: Europe; America; Asia; East Indies. The following 
endemic species occurs in New Zealand. 
Aecidia, where known, occur on the needles of two-leaved species of 
Pinus; the other stages on several families of dicotyledons. In Gallowaya, 
on the other hand, the teleutospores (the only stage known) occur on Pinus, 
and on account of this fact, and because only teleutospores are known in 
the cycle, Arthur (1906, p. 336) placed it in a separate genus.

20-31 x 14-18 mmm ; epispore hyaline, closely, coarsely and unequally
