I found these popping up from leaf litter, a mixture of last year’s maple and elm, on an August morning. The dappled light, varied from bright to very dark, exceeded the dynamic range of my equipment, so I set up the Sony dslr Alpha700 with the Sony lens DT 18-200mm f3.5-6.3 on a tripod and, using the remote feature, placed the flash at an optimal angle.
“Monotropa uniflora, also known as ghost plant, ghost pipe, or Indian pipe, is an herbaceous perennial plant native to temperate regions of Asia, North America, and northern South America, but with large gaps between areas. The plant is sometimes completely waxy white, but often has black flecks or pale pink coloration. Rare variants may have a deep red color. The name “Monotropa” is Greek for “one turn” and “uniflora” is Latin for “one flowered” as there is one sharply curved stem for each single flower. It flowers from early summer to early autumn, often a few days after rainfall. The fruit, an oval capsule-like structure, enlarges and becomes upright when the seeds mature, at this point stem and capsule looking desiccated and dark brown or black. The seeds of Monotropa uniflora are small, ranging between 0.6–0.8 mm (3⁄128–1⁄32 in) in length.“

“Unlike most plants, it is white and does not contain chlorophyll. Instead of generating food using the energy from sunlight, it is parasitic, and more specifically a mycoheterotroph. Its hosts are certain fungi that are mycorrhizal with trees, meaning it ultimately gets its food from photosynthetic trees. Since it is not dependent on sunlight to grow, it can grow in very dark environments as in the understory of dense forest. The complex relationship that allows this plant to grow also makes propagation difficult.“
“The flowers of Monotropa uniflora are visited by various bee and fly species, most commonly bumblebees. Bumblebees are an important pollen dispersal agent for the plant.“

“Like most mycoheterotrophic plants, Monotropa uniflora associates with a small range of fungal hosts, all of them members of Russulaceae.“
“It is often associated with beech trees.“
“The plant contains glycosides and may be toxic to humans.“
“In addition to various reported medical uses, the plant has been used as an anxiolytic in herbal medicine since the late 19th century.“
