Extrusive rocks are formed outside of earths surface. Intrusive rocks are formed inside earths surface.
Coalesced magma bodies are referred to as plutonic rocks, they have a porphyritic texture or larger crystals since elements are allotted more time to segregate to their desired energy environments and precipitate minerals.
The crystals may display a "Crescumulate texture".
Igneous rocks that form when magma cools on Earth's surface are called extrusive or volcanic igneous rocks. They have a fine-grained texture due to their rapid cooling process.
The Igneous rock formed when magma cools are; 1. Extrusive (Volcanic) Igneous Rock; which are igneous rocks formed when magma cools outside the earths crust. The texture of of extrusive igneous rock is fine grained. 2. Intrusive (Plutonic) Igneous Rock; these are igneous rocks formed by gradual cooling of magma within the earths crust. The texture is coarse grained.

coarse-grained texture due to slow cooling, resulting in larger mineral crystals. Examples of these rocks include granite and diorite.

If it finds its way dowm into the earths crust through rock cycle and then is melted and mixes together to form molten magma, it could re-erupt to the earths surface and form an extrusive igneous rock or cool and solidify within the earths crust as an intrusive igneous rock.
