Stalagmite: definitely not limestone.

 

P1250097

In a lava cave roof, hot gases boil and push molten lava through cracks in the roof’s cooled crust. This lava can spooge out of its stalactite and drop to the ground, creating a stalagmite like this. This formation has a really nice metallic glaze to it, and I saw it in a cave near Bend, OR.

Almost looks like metallic slag drip. Lava tube formations are very cool looking, and hard on the knees.
