Description

0, I. Unknown.
II. Uredosori amphigenous, seated on small angular yellow spots, orbicular, 0.5-1 mm. diam., orange-yellow, pulverulent, pulvinate, surrounded by the ruptured epidermis. Spores elliptical, obovate, or subglobose, 20-31 X 14-18 mium; epispore hyaline, closely, coarsely and unequally echinulate, spines sparsely distributed towards base of spore, 1.5 mmm. thick, cell-contents granular, orange; germ-pores indistinct.
III. Unknown.

Notes

The host is endemic, and is abundant throughout. (Cheeseman, 1906, p. 186.)
This rust is common in certain parts of New Zealand, and is conspicuous owing to the bright orange colour of the uredosori; in certain specimens the entire leaf-surface may be covered with the sori.
The uredo stage alone is known; the uredospores do not closely resemble other species of the genus, differing particularly in being echinulate and not covered with deciduous tubercules.

Caeoma peltatum C.G. Shaw III & C.G. Shaw 1977 [1976]

Description

Type: Rust and Smut Fungi; Description: Spermagonia scattered, minute, pear-shaped, immersed, up to 0.5 mm in diameter; on the upper surfaces of phylloclades; associated with aecia, on stems and phylloclades. Aecia scattered, circular to elongate, orange-yellow, up to 1.5 mm in diameter; on the lower surfaces of phylloclades; on bright golden orange discolourations, up to 10 mm across, on stems and phylloclades. Aeciospores in chains, polygonal to ellipsoid, 24–46 × 17–30 m, covered with reticulately arranged tubercles.

Distribution

Distribution: Waikato, Taupo, Nelson, Buller, Westland.; 1st Record: Shaw (1977).

Notes

Pathogenicity

Significance: The rust causes little damage to the host and is of no importance. It appears to be the only rust recorded on the Phyllocladaceae.; Host(s): Phyllocladus alpinus, P. toatoa, P. trichomanoides.

Uredo fuchsiae (Cooke) Henn. 1903

Description

Type: Rust and Smut Fungi; Description: Uredinia small, circular, waxy, orange-yellow, powdery, up to 1 mm in diameter, surrounded by ruptured epidermis; on the lower surfaces of leaves. Urediniospores elliptical to obovate, 30–40 × 22–28 m, coarsely echinulate, hyaline. This species may be distinguished from the rust of cultivated fuchsias (Pucciniastrum pustulatum) by the larger, bright orange uredinia and larger and conspicuously echinulate urediniospores.

Distribution

Distribution: Northland, Auckland, Waikato, Bay of Plenty, Taranaki, Taupo, Wanganui, Wellington, Wairarapa, Nelson, Buller, Westland, Marlborough Sounds, North Canterbury, Mid Canterbury, South Canterbury, Otago Lakes, Dunedin, Southland, Stewart Island.; 1st Record: Cunningham (1924a: as Coleosporium fuchsiae).

Notes

Pathogenicity

Significance: None.; Host(s): Fuchsia excorticata, F. magellanica, F. perscandens.
