Marginal and facial cystidia: absent.
General Information: This fungus which grows from late spring to autumn is usually associated with a greying and finally a killing of the Sphagnum, noticeable from a distance even in the absence of the fruiting-bodies as paler patches in the rich green bog. Another agaric found only in Sphagnum bogs is Omphalina sphagnicola (Berkeley) Moser with decurrent gills and long, elongate, hyaline spores.
At the margin of Sphagnum bogs, the fungus Mycena bulbosa can be found attached to the base of tufts of rushes.
Potting up a sward of Sphagnum and retaining it in a warm greenhouse during winter favours the bog agarics to fruit when other larger fungi are not available.
