There are 4 locations recorded for Entoloma necopinatum, it is believed that there are no more than 10. The area has been to repeated searches over the past 50 years.
The four finds from herbarium records are:
1963 Horak ZT 62-149
1980 Horak ZT 439
2010 Horak CONC-F 0622
2011 Palfner CONC-F 0717
Collected in 4 different sites, two of which occurred over 35 years ago.
Using the Dahlberg & Mueller (2011) interpretation of criteria that there can be up to 10 mature individuals per mycelium and 2 mycelia per site we obtain no more than 200 mature individuals with 20 mature individuals per population, plus that the habitat is in decline we obtain that under C Criterion: CR C2a(i)
This species is present from southern Bio Bio region to Los Lagos region (no records in Los Rios region), Chile. Not reported in Argentina, and based on habitat differences it is unlikely to be found. EOO 13841 km2. AOO 400 km2.
Population Trend: Uncertain
This saprotrophic species grows individually or in small groups scattered on the ground in mixed Valdivian native forest. It is a very striking species due to its green color.
Forms basidiomes in autumn-winter.
It inhabits coastal areas and foothills. Grows in mixed forest of Nothofagus obliqua and N. dombeyi, between 52 and 440 m altitude.
Its major threat is impacts derived from its limited distribution. In Chile there are few records, and in those areas there is a latent threat from excessive deforestation.
The quality of its habitat has declined due to the disturbance of its area of occupancy, resulting from a change of land use to agriculture and plantation forestry. Not known from introduced exotic plantations, and due to the species nutritional habits, the change in leaf litter from broad leafed litter to pine needles is detrimental to the species and habitat viability.
Revisit historic sites.
