Generate for me a description of a mystical scene outside a cave with basalt walls, green metallic tendrils, and a garden of mushrooms.

Warm light glows from a thick vein of clear crystal intersecting the tunnel. The vein must break through the surface somewhere above and reflect the sunlight down. Green metallic tendrils cobweb the walls, forked lightning forms frozen forever in the rock. A small garden of mushrooms has taken up residence on a shelf in the basalt walls which has managed to accumulate enough soil to support the little forest.
