Liquidambar disease?

I was removing withered leaves from my Liquidambar orientalis and noticed these ridges appearing on some of the twigs. It’s a nursery tree about 2-3 years old. This is my first liquidambar so not sure if this is normal growth for the species or some kind of a fungal disease problem. Looks similar to Euonymus ’Burning Bush’. Anyone familiar with this? If it is a fungal disease any recommendations for treatment?

Perfectly normal. Some Sweetgum has corky bark similar to a Winged Elm.

Thanks Chuck! Good to know.

Corky bark is actually a feature of liquidambar.

Good to know. I haven’t seen it on the mature landscape trees I’ve observed but I’ll look closer now. Live & Learn! Thanks
