Most of the umbrella mass is a gelatinous material - the jelly - called mesoglea which is surrounded by two layers of protective skin. The top layer is called the epidermis, and the inner layer is referred to as gastrodermis, which lines the gut.

epidermis
The jellylike substance you are referring to is called cytoplasm. It is where cell organelles are suspended and where many cellular processes take place.
Hydra exhibit tissue level organization, where cells are organized into tissues but lack specialized organ systems. They have two layers of cells, an outer epidermis and an inner gastrodermis, separated by a jelly-like substance called mesoglea.
First one has three and the second one has two germ layers.
Cytoplasm
it is called a cytosol
mesopyll
The phylum Cnidaria is comprised of animals that are radially symmetrical and have a jellylike material, called mesoglea, between two layers of cells.
