Spores are in end (or polar) view when the long axis of the spore points directly towards the observer. Familiarise yourself with the appearance of the spores in side and face view, so that you can recognise the end view. For the end view it does not make much difference whether you are viewing the spore from one end or the other.
Choose this state if: the end view of spores is nodulose. This state is for spores with large nodules, and not for low protuberances (which are treated as part of the spore ornamentation).
