I agree, since they're called Konoha's Yellow Flash and Konoha's White Fang respectively, I would assume that they would know of each other, and maybe even worked together in a certain mission or as a "Konoha's Colour Duo" or whatever, which would be really cool.

My theory, is that both Hagoromo and Hamura inherited Shikotsumyaku from Kaguya, and the horns are the indication for that. Then Hamura passed on this ability to his branch of the Kaguya Clan, and Hagoromo passed on this ability to Indra, and subsequently his branch of the Kaguya Clan. So this clan is actually two clans with the same ancestor (Kaguya) hence the name, with the Hamura Branch having white hair and peaceful (Kimimaro) and the Hagoromo/Indra Branch having black hair and violent (rest of the Kaguya Clan).

Of course, Asura and by extension Hagoromo inherited Wood Release, which is the counterpart of this ability, where Shikotsumyaku symbolises animal (Kaguya), and Wood Release symbolises plant (God Tree). Plus, their usage are similar too, with both of them being able to protrude out of their skin as sharp weapons, or cover the field with it.
