I don't know of a comprehensive list although it is probably most documented for the species and maybe some older cultivars. To a large extent it would be a trait that people have typically tried to breed out because it can be nuisance. The only easy way I can think of visually in the garden is if it gives itself away by popping up a fan away from the main clump. That's exactly what makes them a nuisance because it can result in cultivar mix-ups.
Interestingly I have a totally white fan of 'Variegated Kwanso' that has appeared about a foot or so from its parent, a known rhizomatous daylily. It's not growing well but is still alive so must be getting some nutrition via the rhizome or it would die, but not enough for a normal growth rate.
