stipe (noun, pl. stipes) – in the most general sense referring to any erect structure supporting the fruiting bodies (see ascomata, ascocarps), conidiomata, or thallus parts like squamules; e. g. in Acarospora the stipe refers to extensions from the lower medulla that typically anchor and elevate the squamule above its substrate; in a more restricted sense applied only to branches of a secondary thallus, i. e., forming a stalk supporting fertile structures or thallus parts; in the most restricted sense used only for an immediate extension from the hypothecium (therefore primarily lacking photobionts), if used in this strict, very narrow meaning, a stipe does not necessarily form a stalk elevating the ascocarp above the thallus surface, but it can also be used for any extension from the hypothecium that anchors the ascocarp within the thallus. Related terms: branch, podetium, pseudopodetium, stalk, stem, trunk.
