Purple Funghi Fever

We found the purple mushrooms on the abandoned world. They were so beautiful. They tasted divine. They smelt wonderful.
We took some home, across the stars, and it became a new craze.
But by the solstice, we wished we hadn't.
For the mushrooms grew. Under our moons, they grew strange.
They sprouted from stomachs, ripping flesh apart. They festered in minds, and many went mad. They split bones, feasted on flesh, and caused mass disease. Millions died.
We escaped, on our ship. We thought we were safe. But the cabin is full of seeds, and the mushrooms are ever hungry.
