I received this staghorn from a friend when she moved from across the street from me. It has always done well for her in basically the same environment it's in now. Hanging from a tree in dappled sun/shade being given a banana peel every so often. Over the past month or so, it has began to show the black/brown marks on the fronds and shields. It only gets rain from nature. Is it getting too much?

Also, why would the top of the fern be brown?

I've attached pictures. Any help is appreciated!

Welcome! to NGA/ATP @porter452.

Everything actually looks completely normal to my eyes.

There are two types of fronds, the foliar fronds (long, draping, spore-baring) and the basal frond (roundish, flattened, from which the foliar fronds grow). These fronds are always in various states of decline (browning) or growth. Thus, what you see are just those fronds in decline. Be aware that the foliar fronds will eventually completely turn brown and fall off the plant. The basal fronds never fall off, growing new, green ones over the brown ones. This actually produces a sponge-line structure, holding moisture for prolonged periods of time and allowing these plants to make it through dry periods. Young staghorns need frequent watering because of the lack of the sponge-like buildup but older, larger staghorns need less watering because of this thick layer of basal fronds. Just Mother Nature at work.

i would suggest a weekly misting. It helps almost all houseplants. Most homes are dry inside.

And a monthly spraying outside can clean out dust from plant pores, which also helps.

Thank you for the info @drdawg. To @yardenman, my fern is outside, but thanks for the tip. I didn't think you responded either, but then saw your comment right under my post. Appreciate the responses.
