I present to you the latest addition to my edible mushroom repertoire: lepista nuda, also known by the homey name blewit, which sounds like you just missed a great opportunity. And you would, if you passed up a chance to eat these mushrooms.
The blewits is a worldwide species (also known as clitocybe nuda, with a cousin lepista saeva in Europe) that likes trees and fallen leaves or other decomposing duff. It is pretty easy to identify and worth taking home, if only for the vivid lilac-to-lavender color.
Blewits like company, both their own and with other mushrooms. It is rare to find just one blewit.
I mentioned recently that I walked right by some blewits on a recent mushroom foray. Yes, I "blewit." But I made amends by returning to that spot a week later, where I picked two pounds in 15 minutes. I also found some blewits near Folsom Lake two days ago, so they are popping now.
Here's what you need to know about gathering blewits:
• They are, in general, a cool-weather mushroom, arriving in the Northeast and Pacific Coast around October and persisting all winter long—so long as there are no extended frosts.
• Blewits have a standard "mushroom" shape: simple cap; a thick, stocky stalk; tight gills. There will be no ring or veil around the stalk.
• The cap should be smooth, almost suede-like. It will have leaf litter stuck to it from time to time, but it will never be slimy or viscid. Blewit caps are often beige to mauve. As the mushroom ages, the edges of the cap will get wavy.
• Look for the lilac or lavender color underneath the cap. The color on a blewit is concentrated on the gills, although the cap and stalk will be a little purple, too. The gills are close together.

• Blewits like company, both their own and with other mushrooms. It is rare to find just one blewit, and they will often pop up in loose arcs or rings. Chanterelles are often around them, too.
• Here in California they seem to like to hang around oaks. But they can grow in any pile of decomposing stuff. Blewits will return year after year in the same spot if there is a fresh supply of litter, mostly fallen leaves.
• When you do a spore print—cut the cap off a mushroom and place it, gills down, on a white piece of paper—the spores should be dull pink to pinkish beige.
• Blewits have a slight aroma, which I think smells like lilacs. David Arora in Mushrooms Demystified says they smell like frozen orange juice.
There are a few other blue-to-purple mushrooms around, but none that meet all these requirements. If you have mushrooms with a suede-like cap, stocky stalk, tight, vivid purple gills, a slight but pleasant aroma, and pinkish-tan spores, you have a blewit.
Armed with a positively identified bag of blewits, I went to the interwebs and my books to see how best to cook them ... and I largely came up empty.

Apparently blewits don't merit the praise and adulation that chanterelles, porcini, or morels do. I found no author who detailed the pluses and minuses of particular cooking methods, and only hints at what other foods go well with blewits. Shallots, butter, and cream for certain. One author says they like anise flavors, like Pernod or fennel. Another says they don't like garlic.
