thank you for that web link. After staring at all the pics, I still don't know what to look for to tell them apart but i'll keep on looking at the pics to see if i can come to some kind of pattern.

maybe tightness/closeness of polyps or the length of the shaft or something could possibly differ between them but i dunno.
