Additions to the Rust Fungi of New Zealand, II

[Received by the Editor, March 30, 1955.]

Abstract

Rusts recorded for the Dominion now total 162. A new species of Milesia infecting Lindsaya cuneata C. Chr. and eight species introduced into New Zealand are described and illustrated. Eighteen new host records are given.

Since the publication of Additions to the Rust Fungi of New Zealand I. (Cunningham, 1945), the following rusts and hosts have been collected, bringing the total for the Dominion to 162 species. This number includes French bean rust (Uromyces appendiculatus (Pers.) Unger) which was recorded on Phaseolus vulgaris L. by Brien & Jacks (1954), Puccinia alboclava Baylis and Uredo puawhananga Baylis recorded on Clematis species by Baylis (1954).

In this paper species are arranged according to the classification given by Cunningham (1931).

The writer wishes to thank Dr. G. H. Cunningham and Miss J. M. Dingley for their advice and Miss Beryl J. Hooton for Latin description of one species.

Wellington: Floor of beech forest near Upper Hutt, March, 1953, A. J. Healy; type collection, P.D.D. herbarium No. 14069.

Part of the type collection was sent for identification to Dr. J. H. Faull, Massachusetts. He replied that the species was new and that the genus Lindsaya had not previously been recorded as a host for Milesia.

Following Faull (1932) Milesia White is accepted as valid over Milesina Magnus. Magnus rejected White's name because he did not describe the teleuto-sporial or “perfect” stage, and redescribed the genus under the name Milesina. Rogers (1948), in discussing the conservation of Milesia against Milesina, pointed out that since the type collection shows teleutospores the incompleteness of White's original description should not affect the validity of Milesia.

As yet, Milesia histiopteridis (G. H. Cunn.) Faull is the only other New Zealand representative of this tropical rust genus. It differs from M. lindsayae in having verrueose not echinulate uredospores.

Since first collected, in February, 1954, the rust has become widespread in the Auckland Province on Euphorbia peplus and has been recorded from Christchurch. A European host, E. helioscopica L., often grows near rusted E. peplus in Auckland without itself becoming infected, a fact which indicates the existence of biological races within the species. Mueller (1907) gave specific rank to these races, but later workers (Jorstad, 1953) recognise Melampsora euphorbiae as a compound species consisting of several biological races confined to various Euphorbia species.

Cunningham (1931) named from New Zealand Melampsora novae-zelandiae on the indigenous Euphorbia glauca Forst. f. Only uredospores are described which differ from those of M. euphorbiae in that the uredospore wall is slightly thicker and more sparsely echinulate. Until teleutospores have been found it is preferable to retain M. novae-zealandiae as a separate species.

When Schroeter transferred Uredo hypericorum Dc. to the genus Melampsora he described only uredospores. Since Winter first recorded teleutospores in 1884, his name has priority over that of Schroeter.

The taxonomic position of this species has caused much discussion. Dietel (1922) believing it to have characters intermediate between those of Coleosporium and Melampsora, erected the genus Mesopsora, containing but one species Mesopsora hypericorum. However, later workers (Jorstad, 1953; Bisby & Wilson, 1954) considered the evidence insufficient for such a change and continued to use the name Melampsora hypericorum.

Grove (1913) classified the spores as caeomospores, since they were borne in chains Dietel (1922) however, pointed out that uredospores of many genera may be borne singly or in chains and that pycnidia have not been found; by comparison with similar species he suggested an alternate aecidial host, probably a coniferous one.

Tutsan rust was previously recorded for New Zealand by Baker (1955).

Since Puccinia antirrhini was first recorded by Helson (1953) it has become widespread on Antirrhinum majus L. in Auckland City and has been recorded from Nelson, Blenheim and Christchurch.

Although P. antirrhini is a cosmopolitan species and has been known from America for over sixty years, the alternate aecidial host has not been found.

Mains (1924) showed that teleutospores are unable to reinfect antirrhinum plants. The rust appears to maintain itself by a repeating uredo-cycle.

Puccinia cynodontis, native to the Mediterranean region, has become widespread in most warm countries of the world.

Much work has been carried out to relate P. cynodontis with its alternate aecidial host. Guyot & Viennot-Bourgin (1942), discussing these alternate hosts, stated that Tranzschel first established the relationship of P. cynodontis with Aecidium plantaginis Ces., which infects plantains. He and other workers showed by inoculation experiments that P. cynodontis has numerous aecidial hosts belonging to several genera including Plantago, Viola, Delphinium, Valerianella and Mercurialis. No alternate host has yet been established for New Zealand.

For North America, Savile & Conners (1951) distinguished three geographical subspecies which they separated on host species, on the number of germ pores in uredospores and the position of thickening on the teleutospore wall. The New Zealand collection is comparable with their subspecies armeriae.

In the collection examined, immature aecidiosori are present on the same leaf as teleuto- and uredosori, a feature which according to Saville & Conners (1951) distinguishes Uromyces armeriae from U. limonii (Dc.) Lev. the rust infecting Limonium species. Pycniosori which have seldom been recorded overseas are not present on the New Zealand collection.

The host, an introduced species, is locally abundant in the north of the North Island.

Arthur & Bisby (1922) recognised two species of rust infecting the genus Bidens; one with a life cycle involving pycniospores, uredospores and teleutospores was described by Arthur as Klebahnia bidentis (P. Henn.) Arth. (= Uromyces bidenticola Arth.) while a second with a life cycle involving only teleutospores was named Teleutospora bidentis (Lagerh.) Arthur & Bisby (= Uromyces bidentis Lagerh.). Since teleutospores in both appear to be identical, it seems preferable to follow Sydow (1910) who regarded them as forms of a single species.

The host species is confined to New Zealand, Australia and Tasmania.

This species was recorded for New Zealand as Puccinia caricis (Pers.) Reb. by Cunningham (1931). Jorstad (1932) showed that this name “cannot be used as it concerns a rust on Carex praecox Jacq. no doubt of P. silvatica type (to P. dioicae s. lat.) as pointed out by Arthur (1910, p. 223). Uredo caricis Schum. (Enum. pl. Saell., 2, p. 22, 1803) which has been considered the oldest valid name is a homonym; the older Uredo caricis Pers. (Syn. Fung., p. 225, 1801) refers to Cintractia caricis Magn.” Therefore on grounds of priority he revived the specific epithet “caricina”.
