Assessment Notes

Taxonomic notes

According to Maas Geesteranus (1986) the name Mycena peltata was misapplied for M. concolor in Smith (1935) and hence according to Maas known from North America.

Why suggested for a Global Red List Assessment?

A species confined to mires -threatened by drainage, sphagnum-mining, intensive farming. The historic decline in western Europe of suitable habitat is very high but much less towards the east where the fungus has yet to be recorded.
Assessed under the A criterion it could qualify as at least VU but currently assessed as LC. In a 100 year scale it would qualify as at least VU.

Geographic range

Apparently extinct in the Netherlands and generally with very few modern records. Known from less than 10 localities in Denmark and likewise in Norway. Known from 13 sites in Germany. It is not represented in the St. Petersburg herbarium so it either absent, rare or overlooked in Russia.
