I understand the need for the want of a list. I admit when I first started looking that is what I did, make a list. Now that I have been doing it a while, and the fact that in the past 6 months there have been several "new" discoveries, I no longer use a list. If I find something "odd" I will check it to known "found" varieties. If I do not find a match I post it on here.
I firmly believe that you will never have a perfect list. Main reason is "the list' is always evolving, and what one expert might deem to be a variety, another might deem to be
PMD or something totally different. This is what I feel makes this an awesome hobby. There are so many different things to collect, and so many different angles in which to approach it. There is no single PERFECT way. Which to me is PERFECT.
