Vol. 19: 227-232 227 New Zealand rust fungi: additions and corrections E. H. C. McKENZIE Plant Diseases Division, DSIR, Private Bag, Auckland, New Zealand Abstract An original specimen of Aecidium otagense Lindsay on Clematis paniculata Gmel. has been located and a lectotype designated. The first record of Aecidium senecionis (Pers.) Lev. (syn. Puccinia lagenophorae Cooke) from New Zealand is discussed. Puccinia aorangi G. H. Cunn. on Celmisia species is reduced to synonymy with the earlier described P. egmontensis G. H. Cunn.1t is suggested that Uromycladium notabile (Ludwig) McAlp. is restricted to Acacia species with bipinnate leaves, whereas U. tepperianum (Sacc.) McAlp. is found on those with leaves reduced to phyllodes or spines. Two rusts. Puccinia microspora Diet. and P. zoysiae Diet., are newly recorded from New Zealand, and 38 additional host records for rust fungi previously known from New Zealand are listed. Keywords Uredinales; Aecidium otagense lectotype; rust records; host plant records; mycology: New Zealand Aecidium otagense on Clematis Lindsay (1867) described and figured Aecidium otagense Lindsay, on three different host plantsClematis hexasepala DC .• Epilobiumjunceum Sol .• and Microseris forsteri Hook. f. Subsequent authors (e.g., Cunningham 1924, 1931; Baylis 1954; Dingley 1969) have restricted recordings of the rust to Clematis species, and there has been no further mention of this rust on the other two hosts. Lindsay (1867) doubted if more than one species of rust was involved, although he did suggest that there might be different "species. varieties or conditions." Cunningham (1931), giving full descriptions of aecia and aeciospores of A. otagense on four species of clematis. raised the possibility that Lindsay (1867) may have erected his species on aeciospores of Puccinia c1avata P. et H. Syd .• which is common on C. hexasepala (syn. C.forsteriGmel.). Four rusts occur on Clematis species in New Zealand. Only one of these. A. otagense, produces deformities in the flowers and leaves of the host, similar to those fIgUred by Lindsay. As Cunningham ( 1931) stated, Lindsay' s description of the fungus is scant, but his description and figures of host symptoms leave no doubt that he was describing the rust now accepted as A. otagense. Both Cunningham (1931) and Dingley (1969) thought that the type specimen of A. otagense was no longer extant. but two of Lindsay's three collections have been located in the Herbarium, Royal Received 23 September /980 Botanic Garden. Edinburgh (E). One of these is A. otagense on C. paniculata Omel. (Fig. I) and is herein designated the lectotype. Lindsay (1867) listed C. hexasepala (syn. C. fOrslefl) as the host, but this species is found only from Kaipara Harbour to the Cook Strait area, and not in Otago. The herbarium label (Fig. 2) has been altered from C. indivisa Willd. (syn. C. paniculata) to C. hexasepala. In his paper, Lindsay gave the common name of the clematis as puawananga, a name applied to C. paniculata and not to C. forsteri. which does not have a common name. The host has been confirmed as C. paniculata by Miss B. Macmillan of Botany Division. DSIR. The other Undsay specimen is of a rust labelled A. otagense on Epilobiumjunceum. This rust is the aecial stage of Puccinia pulverulenta Grev. The only other rust occurring on Epilobium in New Zealand is Pucciniastr,!m epilobii Otth .• which does not produce an aectal stage under New Zealand conditions. E. junceum is a nomen confusum (Allan 1961). but unfortunately the host in the specimen is immature and cannot be positively identified with any presently accepted species. Lindsay's third rust specimen. on Microseris {orsteri (syn. M. scapigera Sol. ex A. Cunn.) Sch. Bip.). cannot be located and is presumed lost. Puccinia hieracii (Roehl.) Mart. has been recorded on Microseris in North America (Cummins 1978) and Aust~ia ~McAlpine ~895, as P. microseris McAlp.). EXammatlon of speClmens of M. scapigera in the Herbarium.

The aecia of P. hieracii are uredinoid, and presumably were not the structures seen by Lindsay on M. scapigera. P. hieracii does not match the description or figures given by Lindsay for his rust on M. scapigera. The existence of another rust on Microseris in New Zealand must await confirmation.

(groundsel) in New Zealand, Puccinia lagenophorae Cooke and the recently reported (Sheridan 1978) Coleosporium senecionis (Pers.) Lev. Puccinia lagenophorae was first recorded from New Zealand by Cunningham (1923) on Lagenophora species, and later (Cunningham 1931) on S. vulgaris. Cooke (1879) recorded Aecidium senecionis Desm. on S. vulgaris from New Zealand. Aecidium senecionis was regarded by Sydow & Sydow (1904) as the aecial stage of the European rust, Puccinia silvatica Schroet., which has never been recorded in New Zealand, and by McAlpine (1906) as the aecial stage of Puccinia tasmanica Diet., a synonym of P. lagenophorae (Wilson et al. 1965). The original New Zealand collection of A . senecionis in the Herbarium, Royal Botanic Gardens, Kew (K), has been examined. The aeciospores match those of P. lagerrophorae; thus Cooke (1879) is the first to have recorded this rust for New Zealand. Puccinia aorangi synonymous with P. egmontensis Cunningham (1923) described pycnia and telia of a new rust, Puccinia egmontensis G . H. Cunn. found on Celmisia glandulosa Hook. f. (POD 491-type). He described (Cunningham 1930) another new rust, P. aorangi G. H. Cunn. on C. major Cheesem. (POD 3463-type), said to differ from P. egmontensis in possessing more prominent telia, broader spores, and stouter pedicels. The Herb. POD collections of these two rusts have been re-examined . P. aorangiis represented in Herb. POD by two specimens, the type collection on C. major and a later collection on C. gracilenla Hook. f. There are several collections of P. egmontensis, all of which are on C. glandulosa. Teliospores of these two rusts are shown in Fig. 3. Teliospores of P. egmonlens.is from C. glandulosa measure (49-)50-64(-67) x (18-)20-25(-27) ILm (mean 58 x 21.5 ILm), whereas those of P. aorangi from C. major measure (46-)48-66(-69) x (19.5-) 21-25(-28) ILm (mean 56 x 23 .5ILm). The small difference in mean spore measurements and the lack of other consistent differences between these two rusts are grounds for considering them as a single species. Consequently, P. aorangi is reduced to synonymy with the earlier species, P. egmontensis. In 1931 Cunningham redescribed P. egmonlensis, adding a description of aecia, and giving details of a second collection (POD 3383). This collection contains aecia and aeciospores as described by Cunningham (1931), but does not bear any telia. There are II other collections in Herb. POD labelled P. egmontensis, all of which bear only telia and not aecia. Whether there is any connection between the aecia and telia described by Cunningham (1931) is Fig. 3 Teliospores of Pllccinia aorangi G. H. Cunn. (A, POD 3463-type; B, POD 21665) and of P. egmontensis G. H. Cunn. (C, POD 49 I-type; 0, POD 15798). Specimens mounted in hydrous lactophenol. uncertain, and until a connection can be established, it is best to regard the aecia as those of a separate, unknown rust. Uromycladium notabile on Acacia vertlcillata, a doubtful record Cunningham (1931) recorded the gall-fonning rust Uromycladium notahile (Ludwig) McAlp. on Acacia \'erticillata (L 'Her.) Willd. and gave details of two collections-Titirangi, 200 m and North Shore, Auckland, sea level. Unfortunately, neither of these specimens is in Herb. POD, nor are there any other specimens of U. notahile on A . verticil/ala. There are, however, 10 collections of another gall-fanning rust, U. tepperianllm (Sacc.) MeAlp. on A. \'erticillata. One of these , in a spirit collection, is from the same general locality as one of Cunningham's 1931 specimens-Acacia verticillata gall, 6.1V.1948, North Shore. In Australia only U. tepperianum has been recorded on A. verticil/ata. From the literature it appears that U. nolahile is probably restricted to Acacia species with bipinnate leaves, whereas U. tepperianllm is found on those with leaves reduced to phyllodes or spines. The combination of U . nOlahile on A. \'erlicillala appears unlikely , and the 230 recorded occurrence of U. nOlabile on A. verticillala in New Zealand must be regarded with suspicion. The first recording of U. lepperianum on A. verticil/ata in New Zealand was made by McNabb (1966), although the host was misdetermined as A. riceana Hensl.

Uredinia amphigenous or on sheaths and stems, pale yellow or colourless. Urediniospores (15-)16-18(-20) x (12-)14-16(-16.5) #Lm, obovoid or broadly ellipsoid, wall 1-1.5(-2) #Lm thick, colourless, echinulate, germ pores obscure, scattered.

Pelrie (PDD 40333-CHR 5854) II. This species is characterised by the small urediniospores. The New Zealand collections match the description of P. zoysiae in Cummins (1971). Cummins states that the uredinia are bright yellow when fresh, and that in some collections the urediniospores have a thickened apical wall. Overseas telia have been recorded, and aecia have been described on Paederia species. This rust is known from Manchuria, China, Japan, and the United States, on Zoysia species. DESCRIPTION OF NEW ZEALAND MATERIAL: Aecia unknown. Uredinia amphigenous, mainly on abaxial surface, cinnamon-brown, with colourless or pale golden, capitate paraphyses, the apical walls of which are thickened to 6-14 #Lm. Urediniospores (24-)25.5-30(-35.5) x (19-)20.5-23(-24) #Lm, obovoid or broadly ellipsoid, wall 1.5-2.5 #Lm thick, cinnamon-brown, echinulate, germ pores 4, equatorial. Telia on abaxial surface, blackish brown. Teliospores (25-)26-36(-38) x (17-)18-22(-24) #Lm, slightly constricted at septum, obovoid or oblongobovoid, wall 1.5 #Lm thick at sides, 2-4 #Lm at apex, smooth, cinnamon-brown; pedicels up to 20 #Lm, persistent, pale brown. on Imperata cheesemanii Hack.

The Kermadec Islands collections of this rust match the description and figures in Cummins (1971), although the urediniospores in the present collections are slightly larger than those described by Cummins, and match those of another rust, P. rujipes Diet. on Imperata cylindrica (L.) P. Beauv. However, the teliospores of P. rujipes have long (70-90 #Lm) pedicels whereas those of the present collections and of P. microspora are much shorter (up to 20 #Lm). Previously, the rust was known from Brazil, south-western United States, Japan, China, Borneo, and Papua New Guinea, on species of Imperata. Erianthus. Hemarlhria. and Rottboellia.
