A rock with little to no grain development and a vesicular texture is typically called a vesicular rock. It is formed from a volcanic eruption, where gases trapped in the lava create bubbles or vesicles. The most common example is vesicular basalt.
Pumice
Textures of volcanic rocks include aphantitic (mineral grains are present but microscopic) , porphyritic (some grains are visible to the naked eye), glassy (all or much of the rock lacks a crystalline structure), and vesicular (solidified gas bubbles are present).
I may be wrong, but it might be volcanic rock.
Volcanic glass, or pumice (vesicular obsidian).

It has a vesicular texture.
Scoria is a highly vesicular (porous), dark colored volcanic rock.

Volcanic rocks with gas bubbles are called vesicular. This, however, is a descriptive term rather than an actual rock types. Some vesicular volcanic rocks include pumice, scoria, and vesicular basalt.

* Vesicular rock texture is generally displayed in extrusive igneous rocks which contain many vesicles of trapped air, such as pumice or scoria. * Igneous rocks containing holes which were produced as gases escaped from the upper part of lava flow.
Pumice. It floats on water due to its vesicular structure.
