Here's a biological mineraloid.

Name: Asterite

Appearance: Fibrous or globular. Colour depends on presence of pigments. Waxy.

Properties: Highly water-resistant. Can be burned for fuel, but is inefficient. Tends to grow out of control in low-gravity carbon-rich environments. Mostly a nuisance.

Occurance: Wherever dyson trees have gone wild.

Rarity: Common, but the mineraloid form is more difficult to find than the overgrown living organism.
