Yes, you are right, Axel...............

In Dana's text book, under Aragonite:

Stalactite; Coralloidal: In groupings of delicate interlacing and coalescing 
stems, of a snow-white color and looking a little like coral; often called 
Fos-Ferri (Eisenbluthe, Germ.)

Me: It is a bit difficult to imagine these forming, as they are massed in 
large adhered groups, often showing curls and curves, with no matrix.

Thanks!!

( I have about 50 of these, would you like one?)

Larry
