H. C. McKENZIE Plant Diseases Division, DSIR Private Bag, Auckland, New Zealand Abstract Three fungi, Entyloma fergussonii (Berk. et Br.) Plowr. (on Myosotis arvensis (L.) J. Hill), Mycovellosiella brachycarpa (H. Syd.) Deighton (on Solanum mauritianum Scop.), and Pseudopeziza geranii Rodway (on Geranium potentilloides L'Her. ex DC.) are recorded in New Zealand for the first time; 50 new host records are given for 32 other species. Two existing records, Mycosphaerella spissa H. Syd. on Coprosma robusta Raoul and Albugo candida (Pers.) O. Kuntze on Lepidium ruderale L. are deleted following redetermination of the hosts. Keywords new records; plant diseases; fungi; Entyloma fergussonii; Mycovellosiella brachycarpa; Pseudopeziza geranii; New Zealand INTRODUCTION Fifty three pathogen/host records are newly listed for New Zealand. Included amongst these combinations are 27 rusts, 5 smuts, 5 white rusts, 4 powdery mildews, and several leaf spots and blotches. The host plants, many of which are indigenous, are of little economic importance. Three fungi, Entyloma fergussonii (Berk. et Br.) Plowr., Mycovellosiella brachycarpa (H. Syd.) Deighton, and Pseudopeziza geranii Rodway were previously not known from New Zealand. Two existing records, Mycosphaerella spissa H. Syd. on Coprosma robusta Raoul and Albugo candida (Pers.) O. Kuntze on Lepidium ruderale L. are deleted following redetermination of the hosts. Specimens of all the fungi are housed in the Received 21 April 1987; revision 3 August 1987 Herbarium, Plant Diseases Division (PDD), Department of Scientific and Industrial Research, Auckland, and for each specimen the PDD accession number is given. For the rust fungi, II indicates the presence of uredinia and III the presence of telia. Specimen localities are assigned to geographical areas as defined by Crosby et al. (1976). An asterisk indicates that the host is introduced. Fungi previously unrecorded in New Zealand Entyloma fergussonii (Berk. et Br.)

This rust was first recorded in New Zealand by Versluys (1977). Since then it has become very common, and is now known on 12 Oxalis spp. A. J. Healy (pers. comm.) has supplied some interesting observations on the rust. He noted that uredosori were epiphyllous on O. versicolor growing in Riccarton, Christchurch. Three Auckland specimens examined were also found to have epiphyllous pustules. This is in contrast to the other host species, and to published descriptions, McKenzie-New plant disease records in New Zealand where the uredosori are mainly hypophyllous. Although growing, in Riccarton, in close proximity to heavily infected plants, O. bowiei, O. hirta, and O. pes-caprae had only slight infection, whereas other species (0. corniculata L., O. deppei, O. exi/is A. Cunn., O. latifolia HBK, and O. tuberosa Mol.) were free of infection over a 2-year period. In December 1986, however, P. oxalidis was noted on two leaflets of O. deppei, although there was no evidence of rust on this plant in previous seasons. Elsewhere in New Zealand, P. oxalidis has been previously recorded on O. corniculata and O. lati/olia. Although the rust is of American origin, it has established in New Zealand on host species from South America, Mexico, and Africa. Puccinia tararua G. H. Cunn.

Auckland, Massey, Lion Safari Park, 13.X.1985, E. H. C. McKenzie (PDD 50383) II. RUST. Widespread on Medicago spp. and recently found on L. subbiflorus Lag. (McKenzie 1981).
