Collections Examined

Hosts : Celmisia discolor Hook. f. On leaves. Herb. No. 384. Mount Peel (Canterbury), 900 m., H. H. Allan! 6 March, 1921. Tooth Peaks (Otago), W. D. Reid ! 7 April, 1921. (Type.) Celmisia Sinclairii Hook. f. Herb. Nos. 385, 435. Lake Harris track (Otago), 1,060m., W. D. Reid ! 6 May, 1921. Mount Isobel, Hammer (Canterbury), 1,200 m., W. D. Reid ! 4 Nov., 1921. Celmisia prorepens Petrie. Herb. No. 385. Mount Dick (Otago), 1,400m., W. D. Reid ! 24 April, 1921.

Description

0. Spermogones scattered, sparse, epiphyllous, immersed.
I. Aecidia amphigenous, chiefly epiphyllous, orange-yellow, scattered or arranged in small orbicular groups. Peridia cylindrical, erumpent, standing 1 mm. above the leaf-surface, 0.1 mm. diam., margins incurved, at first dentate, becoming deeply lacerate, white. Spores subglobose, elliptical, or obovate, 36-42 X 28-34 mmm.; epispore hyaline, covered with densely-packed deciduous tubercules, 3 mmm. thick, cell-contents orange-yellow, granular.

Latin

0. Spermagoniis raris, sparsis, epiphyllis, immersis. I. Aecidiis amphigeniis, praecipue epiphyllis, flavis, raris vel parvis catervis. Peridiis cylindricis, erumpentibus, super superficiem exstitis ad 1 mm., 0-1 mm. latis, marginibus incurvatis, primum dentatis demum profunde laceratis, albis. Aecidiosporis subglobosis, ellipticis vel obovatis, 36-42 X 28-34 mmm.; episporio hyalino, solide deciduis tuberculin tecto 3 mmm. crasso, contentu flavido, granuloso.

Notes

All three hosts are endemic, and all are confined to the mountain-ranges of the South Island. (Cheeseman, 1906, pp. 303-6.)
This species is characterized by the small cylindrical peridia, and more especially by the fact that the epispore is covered with a layer of closely-packed, coarse, deciduous tubercules. Aecidium Celmisiae-Petriei is the only other New Zealand species that possesses this feature.

Aecidium celmisiae-petriei G. Cunn. 1924

Collections Examined

Host: Celmisia Petriei Cheesem. On leaves. Herb. No. 382. Lake Harris track (Otago), 1,100m., W. D. Reid ! 6 May, 1921. (Type.)

Description

0. Spermogones scattered, sparse, seen only in sections.
I. Aecidia hypophyllous, in linear groups, seated on discoloured spots visible on the upper surface, forming conspicuous bullate areas beneath the tomentum of the leaf, long covered. Peridia cylindrical, 0.25 mm. diam., distorted by pressure of the overlying tomentum, margins incurved, deeply and irregularly lacerate, white. Spores elongate-elliptical, or obovate-elliptical; 36-52 X 20-25 mmm.; epispore hyaline, densely covered with deciduous tubercules, 2 mmm. thick, cell-contents granular, orange-yellow.

Latin

0. Spermagoniis sparsis, raris. I. Aecidiis hypophyllis, in linearibus catervis, in maculis discoloratis, et bullatis infra tomentum folii diu tectis. Peridiis cylindricis, 0.25 mm. latis, tomento premente distortis, marginibus incurvatis, profundis lace ratis; albis. Aecidiosporis longis-ellipticis vel obovatis-ellipticis, 36-52 X 20-25 mmm.; episporio hyalino, cum solide deciduo tuberculo tecto, 2 mmm. crasso; contentu granuloso, luteo.

Notes

The host is endemic, and confined to the mountains of Otago. (Cheeseman, 1906, p. 311.)
This species differs from others on Celmisia on account of the elliptic-oblong spores, and the presence of deciduous tubercules on the epispore. The aecidia are permanently covered by the dense tomentum which clothes the leaf-surface; this soon causes the peridia to become malformed, so that sections of young specimens are necessary to determine the shape and size of the peridium.

Aecidium celmisiae-discoloris G. Cunn. 1924

Notes

Aecidia are formed on undersurfaces of leaves of a number of species of Celmisia; the hosts and the rust are endemic and mainly confined to alpine herb fields in the South Island of New Zealand.
