Hi I’m Ashley, you can call me that or Wojo. I also go by Exclamation! on occasion.

The article is from 2011, but it’s still really fascinating.

When Robert Coffan discovered psathyrella aquatica, he wasn’t looking for it. The professor waded into the Rogue River during a picnic with his family. Coffan spotted a tiny pale mushrooms growing out of the riverbed in the flowing water, and realized he was seeing something strange.

Coffan convinced a pair of mycologists at Southern Oregon University, Darlene Southworth and Jonathan Frank, to come take a look. Five years later, the team introduced Coffan’s discovery to the world as a new species. Psytherella aquatica is the only species of true, gilled mushroom that grows underwater, though there are aquatic cup fungi. “It looks like something you could buy at Safeway and put on a pizza” Southworth says.

But getting the scientific community to accept a new species can be as challenging as collecting a mushroom growing underwater for the first time. At first glance, psathyrella aquatica looks identical to hundreds of known species of little brown mushroom that grow on land. Its genus, psathyrella, is a group of mushrooms famous for giving mycologists headaches and being difficult to tell apart. The mycologists compared samples of their underwater mushroom and its spores under a microscope to hundreds of dried specimens in the psathyrella genus.

Now the mycologists are trying to understand how aquatica adapted to a life aquatic, and where exactly it lives. So far, they’ve only found two populations of the mushroom fruiting in a single mile stretch of the Rogue River, not far from Crater Lake National Park.

New species of underwater mushroom found growing in the Rogue

The International Institute for Species Exploration has named its top new species discovered in 2010, and an Oregon mushroom, Psathyrella aquatica, is on the list. Aquatica is the first species of mushroom with gills that scientists have observed fruiting underwater.

Robert Coffan, an Adjunct Professor of water resources at Southern Oregon University, found the mushroom in 2005 while wading in the Rogue River on a visit with his family. Biologists at Southern Oregon University studied the mushroom and decided last year that it is a genetically unique species that grows in river gravels and on submerged logs, and wasn’t accidentally washed into the river.

Coffan says several things make the discovery of this new species particularly exciting. Coffan wants to know how the species he discovered reproduces, given that gilled mushrooms usually reproduce using spores that travel through the air. And he says it raises the question of whether other species of gilled mushroom could be found in streams.

The mushroom has only been found in two locations on the upper Rogue River, about 1500 feet apart. Coffan is reluctant to say exactly where he’s found the species until more populations have been identified.

Here’s a BBC slideshow on the mushroom and the other new species highlighted by the IISE today.

Psathyrella is a large genus of about 400 fungi, and is similar to the genera Coprinellus, Coprinopsis, Coprinus and Panaeolus, usually with a thin cap and white or yellowish white hollow stem. But the caps do not self digest as do those of Coprinellus and Coprinopsis. Some also have brown spores rather than black.

These fungi are often drab-colored, difficult to identify, and inedible, and so they are sometimes considered uninteresting. However they are quite common and can occur at times when there are few other mushrooms to be seen. The first report of a gilled mushroom fruiting underwater is Psathyrella aquatica.

The MO Name Pages are bizarre and they have nothing to do with MO Observations, which are the core of MO. I would deprecate them all. MO would be much better, more professional without them. Adolf

Just this morning I developed the term “Homoeostic Resilience”. according that theory, every more sophisticated system deteriorates to the least common denominator of its users. This is well documented by this page. AC
