Kidney fern sori
Sori are the spore-producing structures of ferns. Typically they are found on the back of fern leaves but in this case they are lining the edge of a kydney fern. The fern is distinctive for its undivided, kidney-shaped fronds, which give the plant its English common name. Hymenophyllum nephrophyllum is a fern species endemic to New Zealand where it occurs on the floor of moist forests. The photo is an in-camera focus stack. f 8, 1/100sec, Olympus 60mm macro lens f 2.8.
