In Plant anatomy, a pit connection is a hole in the septum between two algal cells, and is found only in the red algae - specifically, all orders except the Porphyridiales and haploid Bangiales. They are often stoppered with "pit plugs". They are in fact neither pits, nor connections, yet the term remains in use due to its longevity. By contrast, many fungi (only ascomycetes and basidomycetes, as other groups lack septa) contain septal pores - an unrelated phenomenon.
