Please describe a spooky cave in the wilderness with quartz crystals and phosphorescent fungi.

High above the door of this hollowed out room, a large crack in the mountainside lets in thin streams of moonlight. Over the years, it has also let in snow which has melted and frozen many times to form a line of ice stalagmites under it. The grey light falls on a huge nest built from a collection of whole trees and bushes as well as bits of collected matter like clothing and boots. A leaning altar is almost completely buried in one of the stalagmites.
