Mahonia identification

[kerplunked]

I'm pretty sure this is some kind of mahonia, but i'm not sure which species? Perhaps an aquifolium? As you can see the berries come off short red spikes, and the leaves have particularly short spikes, whilst some are starting to turn red as the year turns toward autumn. I hope this is any help.

Thanks

I would agree that it is Mahonia aquifolium
