Steccherinum is a widely distributed genus of toothed crust fungi in the family Steccherinaceae.
Taxonomy Steccherinum was circumscribed by Samuel Frederick Gray in his 1821 work A Natural Arrangement of British Plants.
Description Steccherinum fungi have a range of fruit body morphologies, including resupinate (crust-like), effused-reflexed (crust-like with the edges extending outwards to form caps), or pileate with either a stipe or only a stipe-like base.
