Deconica inquilina is a species of mushroom in the family Strophariaceae.

Formerly a member of the genus Psilocybe (well known for its psilocybin containing members), this species belonged to the non-blueing (non-hallucinogenic) clade[1] and was consequently moved to Deconica in 2009.

Deconica inquilina is found growing on decaying grass.

It is very widely distributed, reported from North America, South America and Europe.
