To act penuriously means to do something in a stingy or extremely frugal way, almost to the point of being miserly. It suggests a strong aversion to spending money, even when it's necessary. Think of Scrooge McDuck, swimming in his money bin but still pinching pennies. It's more than just being careful with money; it's about hoarding it. Unlike acting generously, penuriously implies a deep reluctance to part with one's wealth. It suggests extreme poverty, or an unwillingness to spend.
