==Mycocrete==
There is a special mushroom that only grows at freezing temperature. When ground to a powder, dissolved in water with some sawdust, and frozen, the ice exhibits unusual properties. The ice is stronger than any simple brick and mortar, and can last half a summer before showing any signs of weakness or melt.

In time, the mushroom seems to grow into the ice, further reinforcing it. Light and heat stops this growth, but much is needed to truly weaken the cement.

Mycocrete is primarily produced near, but not at, the polar regions.What few lands there are are dug into caves and seeded with fresh samples. They are shipped in powder form, and serve as major sources of funds for inhabitants of the Far North or South.
