520 3 |a It is shown that if $$X$$ X contains a closed uncountable discrete subspace, then the Tychonoff plank embeds in the hyperspace $$CL(X)$$ C L ( X ) of the non-empty closed subsets of $$X$$ X with the Fell topology $$\tau _F$$ τ F as a closed subspace. As a consequence, a plethora of properties is proved to be equivalent to normality and metrizability, respectively, of $$(CL(X),\tau _F)$$ ( C L ( X ) , τ F ) . Countable paracompactness, pseudonormality and other weak normality properties of the Fell topology are also characterized.
