Effused-reflexed is a term used to describe a mushroom on a vertical surface that is partially resupinate and partially pileate. The pileate portion of an effused-reflexed fruiting body is necessarily sessile. The part that's sticking out is sometimes called the reflexed portion, and the resupinate part is sometimes called the effused portion.

Effused-reflexed — an effused basidioma (fruiting body) whose margin grows away from the substrate to form a small cap, or pileus (reflexed margin)

Resupinate - bent back with the face upward

Pileated - wearing a cap.

Sessile - no stalk, fixed in one place.

Effused - effusive - stick out
