It's been crazy dry here in northern California this winter. We had some promising rain early in the season and then high pressure systems wheeled around above us, pushing storms to the north or the south or the east, essentially anywhere but here. As a consequence, I haven't seen much fungi this winter, partly because there just wasn't enough moisture and partly because the lack of rain kept the fallen leaves from decomposing, leaving ankle deep piles of crisp, light leaves which, in turn, hid the mushrooms that did fruit. As I've walked through the woods I've occasionally seen withered old specimens uprooted in areas that have been disturbed by squirrels or other creatures rooting around for food.
However, the other day, as I walked through an area in Howath Park where children get pony rides on weekends, I noticed a large pile of horse manure with several mushrooms sprouting merrily out of it. Imagine my joy at finding mushrooms, any mushrooms! That they were fruiting in manure was an added bonus because it meant that I would be able to more easily identify them.
Most mushrooms are saprophytic. That is, they nourish themselves by growing on dead organic matter such as fallen trees, dead insects and animals, fallen leaves and excrement. In the process, the mushrooms decompose the material they feed on, providing what I like to think of as essential janitorial services for the forests and meadows that I walk in. Saprophytic mushrooms are often specialists, so if you find one in, say, horse manure, then it won't be too difficult to find out that you're looking at
Panaeolus papilionaceus. Oh, and if you like learning new words then you'll be happy to know that mushrooms that feed on manure are coprophilous.
Disturbingly, during the research for this post I found that this is considered an edible mushroom. Uh, bon appétit?
The sketches were done with graphite, ink, watercolor, gouache, colored pencil on 8.5 x 11 inch Canson mi-teintes paper. The black circle at the top right is a spore print from one of the mushrooms, an essential identification aid.

The Fungi of California
Every year, at about this time, I find earth tongues, quaint, tiny fungi that look like...well...tongues sticking out of the earth. This year I accidentally noticed that they were fruiting in a location other than the one I normally found them in. Which got me to wondering how common they really are. So, for about two weeks, I walked slow as a snail with my nose to the ground, looking for earth tongues. They are, indeed, quite common in some of the wooded areas, at least at Howarth Park. Aside from the two species I usually find, I got my first glimpse of a gorgeous green species when I found a few fruiting with some of the more familiar black ones. The drawing above is of Geoglossum sp. Without microscopic work, it's difficult to identify the Geoglossums to species.
