Visceral serous membranes line organs. Parietal serous membranes line cavities.

But, the pericardium is actually TRIPLE layered: the visceral layer, the parietal layer, and the fibrous layer (fibrosa).The visceral pericardium is the inner-most layer of the pericardium, and is also known as the Epicardium as it "lays" upon the heart.The Pericardial Cavity lies between the visceral pericardium and the parietal pericardium. This cavity is filled with pericardial fluid which serves as a shock absorber by reducing friction between the visceral and parietal layers. The parietal pericardium is an outer layering wall of the Pericardial Cavity between the pericardial membranes.The outer-most layer is the fibrous layer (fibrosa), and contains nerves, blood vessels, and lymphatics. This is the layer that can become inflamed, called pericarditis. (As opposed to, endocarditis, which is inflammation of the insidelayer of the heart.)
The serous membrane is composed of 2 thin linings. The inter lining, which directly covers the organ, is called the visceral membrane. Over the visceral is the parietal membrane. In between the two is a cushioning fluid. The serous membrane resembles a balloon (visceral) inside another balloon (parietal) with fluid between them.
Between the parietal and visceral pleura.
The connection between the two layers is held together by surface tension. By interfering with this the lungs will not expand with each breath but they will collapse.

The peritoneal cavity is the space between the visceral and parietal peritoneum in the abdominal cavity.
The visceral and parietal layers are belong to a type of epithelial membrane called serous membranes. Serous fluid is a fluid between the two layers that helps them slide past each other without causing friction.
The difference between these two pleura is that the parietal pleura is the outtermost covering of the lung which is adhered to the inner thoracic wall, while the visceral pleura is the lining which is directly adhered to the lung itself. The space between these two pleuras is know as the pleual cavity.
