This species has a minimum AOO estimated as 800 km2, but it could be larger as fruiting bodies are rarely seen, it may occur at fewer than 10 locations, and there is continuing decline in the area, extent and quality of its habitat. It is therefore assessed as Vulnerable B2ab(iii).

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 Aysen region, Chile. It is not reported in Argentina, and based on habitat differences it is unlikely to be found. Its EOO based on known occurrences is 53,100 km2. The AOO was calculated as 400 km2 based on suitable habitat patches by the Chilean national assessment (Ministerio del Medioambiente, Gobierno de Chile 2014). However, this does not include a recent record to the south, which potentially doubles this area: the minimum AOO is therefore estimated as approximately 800 km2, but noting that this may still be an underestimate, yet the total is still likely to be below 2,000 km2.

The suitable habitat is highly fragmented, at least in the northern part of the range. There are currently six locations known based on the threat of changing land use, and even taking into account the additional areas of unsurveyed habitat it is plausible that there are fewer than 10 locations.

There is a lack of data to be able to estimate the population size or trends. Particularly in the north, habitat degradation is likely to be causing a decline. Further declines due to climate change are a potential problem.

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 colour.

It forms basidiomes in autumn-winter.

It inhabits coastal areas and foothills, growing 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. 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 disturbance within its range, resulting from a change of land use to plantation forestry and agriculture (including grazing animals within the forest). It has not been recorded 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.

Climate change is a potential future threat, as increasing frequency and severity of droughts is expected in this region which would negatively impact this species.

Three of the known sites are within protected areas, but protection of the additional sites would be beneficial to this species.

Further research is needed on its distribution, particularly in the southern portion of its range. Further understanding of its ecology would be beneficial.

This species is not utlized.
