The mushroom is two inches long, grows on wood, and is shaped like a phallus, says a statement by the California Academy of Sciences that accompanies this picture.
The new species of stinkhorn mushroom, Phallus drewesii, will be featured on the upcoming cover of Mycologia, a scientific journal on all aspects of the fungi, published by the Mycological Society of America .
The mushroom is named after Drewes, Curator of Herpetology at the California Academy of Sciences, (seen in the photo below, holding the new mushroom), and is described in the July/August issue of Mycologia by Dennis Desjardin and Brian Perry of San Francisco State University.

“Phallus drewesii belongs to a group of mushrooms known as stinkhorns which give off a foul, rotting meat odor,” CAS said. “There are 28 other species of Phallus fungi worldwide, but this particular species is notable for its small size, white netlike stem, and brown spore-covered head. It is also the only Phallus species to curve downward instead of upward.”
“The mushroom emerges from an egg and elongates over four hours,” says Desjardin, who is also a Fellow of the California Academy of Sciences. “Its odor attracts flies who consume the spores and disperse them throughout the forest.”
Desjardin and Perry named the new species after Drewes as an acknowledgment of his “inspiration and fortitude to initiate, coordinate and lead multiorganism biotic surveys on Sao Tome and Principe,” according to the Mycologia paper.
“It’s a wonderful honor and great fun”
“It’s a wonderful honor and great fun to have this phallus-shaped fungus named after me,” Drewes said. “I have been immortalized in the scientific record.”
Phallus drewesii is not the first species to bear Drewes’ name, CAS points out. A small moss frog native to South Africa (Arthroleptella drewesii, in the picture below) and a blind worm snake from Kenya (Leptotyphlops drewesi, in the picture farther down) were described in 1994 and 1996, respectively.

Over a span of forty years, Drewes has embarked on 36 expeditions to 19 African countries, where he has focused on the evolutionary relationships, natural history, and biogeography of amphibians and reptiles, CAS said.
“Recently, he has turned his attention to Sao Tome and Principe, located in the Gulf of Guinea off Africa’s west coast. Although it is a tiny nation–at 370 square miles, only about eight times the size of San Francisco–it hosts a number of plants, fungi, mammals, birds, reptiles, and amphibians found nowhere else on Earth.”
Since 2001, Drewes has organized four multidisciplinary expeditions to the islands in an effort to document their biodiversity and gather data for conservation plans.
Phallus drewesii was one of 225 fungus species that Desjardin and Perry collected during the 2006 and 2008 expeditions.
