Resupinate refers to the growth habit of certain fungi where the cap is oriented downwards. Synonyms for resupinate include adnate, appressed, effused-reflexed, and prostrate. Adnate and appressed are used to describe the growth habit where the lamellae or spines are firmly attached to the stem and run all the way to its base. Effused-reflexed describes the growth habit where the cap is flat and thin and its edge is upturned and reflexed. Prostrate describes the growth habit where the fruiting body is completely flat against the substrate, appearing as a thick crust-like layer. Students studying mycology or those interested in nature and eco-systems may find this information useful.
