1. Results on plant pathogenic fungi
There is scanty information as to what kind of seed-borne fungi are associated with commercial seeds of crops in Japan. Alternaria species found on cruciferous plants seeds in Japan were identified by comparisons with New Zealand isolates of the genus. Our results indicate that an Alternaria on cabbage seed is identical with A. Cheiranthus which causes deterioration of wallflower in New Zealand.
Agricultural produces imported from New Zealand are often decayed in Japanese market by moulding. Post-harvest fungi on vegetables and fruits stored and sold in New Zealand were examined. The spectrum of fungi was somewhat different from those observed in Japan.
2. Results on endophytic fungi
Research on the relationship between endophytes and their host paints has indicated the potential use of biocontrol agents. However, the study should begin with the first step in Japan. Survey of information on distribution and research strategy of glass endophyte in New Ze
aland was undertaken. Characterization of isolates obtained from naturalized plants in Japan are now in progress. A preliminary test indicated that the fungi associated with Cyttaria gall on Notofagus trees collected in New Zealand and Tasmania might be identical. This is the first attempt to isolate the fungus from Cyttaria gall.
3. Study on ammonia fungi in New Zealand
To clarify the sequential occurrence of particular species of fungi on natural soils after treatment with urea or ammoniuiti salt, periodical observation was done in several selected locations in New Zealand. Further, succession of mycoflora during degradation process of an opossum corpse was observed. Mushrooms fruited were essentially the sanie as those in Northern Hemisphere. Some unidentified ones occurred indicate the difference. These studies are the first attempt in Southern Hemisphere.
4. Results on mycorrhizal. fungi
Analysis of SHIRO formed by Hebeloma victoriensis revealed that the fungus was belonging to ectomycorrhizal. While, Cortinarius austrariensis had thick mycelial mat layer with morphologically peculiar mycorrhizae. Our observations suggested that an ecological niche of the fungus in New Zealand forest was similar to some Agarics in Northern Hemisphere. Specimens of mycorrhizal fungi collected in New Caledonia were examined now.
5. Results on edible or useful fungi
Specimens of edible or useful mushrooms and microfungi were collected and pure culture isolation were made. Examples are Aphyllophoraceous fungi and Trichoderma. species.
6. Other results
We collected many specimens of higher plants which were lack in Japanese herbaria. Thus we could make good the shortage of specimens proper to New Caledonia. We also Collected fungi associated with these plants. Identification work is now in progress.
