Assessment Notes

Justification

The estimated number of mature individuals is 400 and the estimated area of occupancy 8km2.


Taxonomic notes

Squamanita squarrulosa is a distinctive and easily recognised rare species. Member of the genus are parasites of other fungi. The species is sequence barcoded.


Why suggested for a Global Red List Assessment?

Squamanita squarrulosa is a distinctive and uncommon species endemic to the North Island of New Zealand.

Preliminary category: Vulnerable: D1 (MI<1000)


Geographic range


Population and Trends

Given the sporadic nature in the appearance of species of Squamanita it is prudent to infer a substantial number of undetected colonies. We infer the presence 2 genotypes, x 40 to account for undetected colonies, x 5 to convert to an estimate of 400 mature individuals. Area of Occupancy 8 km2

Habitat and Ecology

Squamanita squarrulosa is a parasite of other fungi. Other members of the genus are generally quite restricted to specific hosts but the host of the New Zealand species remains unknown. The sparsity of records suggests some barrier to the more widespread occurrence of the species. In general species of Squamanita are uncommon and unpredictable in occurrence.


Threats

No specific threats have been identified but without knowing more about the ecology is difficult to determine if a species with so few known populations will remain viable.
