Among the previously identified pre-Cryogenian macroalgae, ''Longfengshania'' is unique due to it possessing a stipe, blade, and holdfast-like structure.

== Description == ''Longfengshania'' is most commonly found as an oval to discoidal blade sitting on top of a usually thin stipe. Specimens from the Shiwangzhuang and Jiuliqiao formations have probable holdfasts at the base of this stipe.<ref name="Li2024"/>

There is a wide range of sizes between species of ''Longfengshania'', with the largest specimens coming from the Longshan Formation, bearing blades up to {{cvt|13|mm|1}} long and stipes up to {{cvt|20|mm|1}} long. The smallest specimens come from the Doushantuo Formation, with blades up to {{cvt|0.7|mm|1}} or less in diameter.<ref name="Li2024"/>
