You need to explicitly include the assembly, version, and public key token (if it has one).

If you're running .NET 4, try this

Type t = Type.GetType("System.Linq.IQueryable`1[System.String], System.Core, "
     + "Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089");

The reason you don't always have to fully qualify the string is because the extra information can be omitted if the type is within the current assembly or in the Mscorlib assembly. From MSDN:

The assembly-qualified name of the type to get. See AssemblyQualifiedName. If the type is in the currently executing assembly or in Mscorlib.dll, it is sufficient to supply the type name qualified by its namespace.

I think the problem is that you are using Type.Name instead of Type.AssemblyQualifiedName.

Can you take a real non-abstract type signature? For example Type.GetType("System.Linq.EnumerableQuery`1[System.String]") should work for you.
