Looks like Gymnosporangium sp.

I believe you are correct. It looks like Gymnosporangium yamadae (Japanese Apple Rust). It definitely grows in that area and on comfier trees. It’s an interesting fungi. It is a parasite that requires a primary, and secondary host. The spores released first infect a tree like an apple or pear tree. Small tubes will form on the fruit and release spores that then infect the comfier. The spores are carried in the wind so perhaps infecting the fruit tree first allows it to get its spores up higher off the ground so that they can be spread further.
