Aecidium disciforme McAlpine 1906

Collections Examined

Hosts: Hebe glaucophylla (Ckn.) Allan, comb. nov. Mt. Mantell, Westland, 1,700 m., 2/28. G.H.C. Hebe Traversii (Hook. f.) Ckn. et Allan. Mt. Percival, Canterbury, 1,000 m., 1/28. H. H. Allan!

Description

0. Unknown.
I. Aecidia amphigenous, chiefly hypophyllous, distorting and etiolating, systemic, scattered evenly and sparsely over the leaf' surface; peridia sunken completely in the host tissues, 0.6-0.8 mm. diam., at first opening by a minute pore, becoming cupulate when old; peridial cells to 35 mmm. long, thin walled (2 mmm.), orbicular, readily separable, striated. Spores shortly elliptical, or subglobose,. 18-24 mmm. ; epispore hyaline, 2.5 mmm. thick, covered with dense coarse, rounded tubercules, contents reddish-orange.

Notes

The systemic mycelium, completely submerged peridia with their thin walled, readily separable cells, are the characters of this species. McAlpine. records this on Veronica gracilis R. Br. and V. calycina R. Br., and also mentions the fact that it causes thickening and. distortion of the leaves.

Aecidium disciforme McAlpine 1906

Notes

An Australian species recorded by Cunningham (1928) on five subalpine species of Hebe endemic to New Zealand: also on H. stricta (Cunningham, 1945a) and on the Australian species Veronica plebeja (Cunningham, 1945a), which is naturalised in New Zealand. It occurs sporadically in both the North and the South Islands. It causes considerable distortion to leaves of the host. It has never been observed on Hebe sp. in cultivation.

Aecidium disciforme McAlpine 1906

Description

Type: Rust and Smut Fungi; Description: Aecia scattered sparsely and evenly, cup-shaped when mature, completely submerged, 0.6–0.8 mm in diameter; mainly on the lower surfaces of leaves, leaves distorted and etiolated. Aeciospores elliptical or subglobose, 18–24 μm diam., covered with coarse, rounded tubercles.

Distribution

Distribution: Northland, Auckland, Coromandel, Rangitikei, Wellington, Nelson, Buller, Westland, Marlborough, Mackenzie.; 1st Record: Cunningham (1928).

Notes

Pathogenicity

Significance: The rust is rarely found on cultivated species of Hebe.; Host(s): Hebe brachysiphon, H. glaucophylla, H. odora, H. stricta var. stricta.
