Vulnerable: A2. B2ab(iii). Based on an inferred population reduction over the next 20; small geographic range B2 AOO 24 km2; quality of habitat decline (iii) due to tourism pressures and disease management (Waitakare site).
The ectomycorrhizal genus Amanita well studied in New Zealand, with relatively few, and well recorded species. Amanita mumura is a distinctive uncommon endemic species associated with Nothofagaceae and Myrtaceae
Why suggested for a Global Red List Assessment?
Distinct species known from 4 locations and 7 records in North Island of New Zealand and under pressure from land-use change.
Population and Trends
Habitat and Ecology
The species is ectomycorrhizal with Southern Beech (Nothofagaceaea) and with Tea-Tree (Myrtaceae).
Populations in three of the sites (Waitakare, Tongariro, Tararua) are adjacent to popular walking tracks subject to increasing tourism with consequent impact on the immediate areas. The population at the Waitakare site is likely to decrease over the next 20 years as the impact of Kauri die-back on the dominant Kauri forest alters the forest structure. Areas are also likely to be disturbed as a consequence of disease management actions.

Greater survey effort in known sites is required to assess extent of local populations and the immediate threats
