C# System.Collection.Generic: Deriving from Collection

SOLVED Cannot post as answer just yet, something is up with the site. I just forgot to add this:

 using System.Collections.ObjectModel;



Hey guys, I'm struggling to derive a class from Collection of System.Collections.Generic. I am currently implementing a Binary Tree, following msdn's description here : Binary Tree's

Here's the error: Assets/Scripts/NodeList.cs(5,28): error CS0246: The type or namespace name Collection 1 ' could not be found. Are you missing a using directive or an assembly reference?

Error is at line 5

Here's my code generating the error (Node class exists already as taken from MSDN)

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 
 public class NodeList<T>: Collection < Node < T > >
 {
     public NodeList() : base() { }
 
     public NodeList(int initialSize)
     {
         // Add the specified number of items
         for (int i = 0; i < initialSize; i++)
             base.Items.Add(default(Node<T>));
     }
 
     public Node<T> FindByValue(T value)
     {
         // search the list for the value
         foreach (Node<T> node in Items)
             if (node.Value.Equals(value))
                 return node;
 
         // if we reached here, we didn't find a matching node
         return null;
     }
 }
