Hissing mushrooms, no lie!

I don’t know about you, but when I think of mushrooms, I don’t think about what sound they make. So I was thrilled when I captured a delightful video of Urnula craterium hissing quite audibly as they sent out a cloud of spores, after I blew on them. I’ll prepare you as best I can for what you are about to see.

Urnula

I found out they do this because I wanted to take a picture of one and there were little pieces of leaves and things inside the cup (and springtails, seems like there’s always springtails in them), so I was trying to blow the stuff out of it to clean it up a little. There was about a one-second delay, and then it poofed out a cloud of spores. I’d read about this, but didn’t think it was going to be so obvious! This tickled me, and I wanted to capture it on video, so I started trying to make them poof out spores. It wasn't until I got home and watched the video that I could hear it. Maybe, when I was in the woods, I thought I was imagining it.

“Devil’s Urn” is one of their common names. It’s a cup fungus. Here’s more (a rotten image, I know—oddly, I do not have dozens of images of these to choose from, like I do every other thing I take a picture of--). When this cup fungus is young and fresh (above), it’s smooth and velvety, a little floppy, and a nice open shape, almost a cocktail glass. These (below) are starting to show their age and curl inward a little. Right about now is when their spores will poof out if you blow on them. And you can hear it.

So, they come out in spring, they’re pretty common, and are considered harbingers of morels, as in, when these are out, morels should be, too.

They’re usually about 2” tall and maybe 1-1/2” across (occasionally a lot bigger, we found a few honkers that were almost 4” across), with a stalk, and they grow on sticks and smallish logs, and even though it can look like they're growing out of the ground, there’s always a stick down there somewhere.

As they age, they start to toughen up and turn brown and get a cool scaly texture on the outside, and the top starts to close up and magically gets a nifty zig-zag edge (faeries with pinking shears).

They don’t poof out many spores when they’re this old. I know, because after I made the first ones do it, I hyperventilated my way all over the forest for days, trying to make other ones do it.

They’re also called “black tulip” fungus.

Now we’re talkin’! That’s some hot crackle-finish zig-zag Urnula action!

But, we need to talk about this audible spore shooting.

Here’s the video, it’s only 5 seconds long; the first sound is me blowing a blast of air on it, and the next sound is the cloud of spores being released.

MOVIE of Urnula craterium releasing spores and HISSING!


I posted this video on Facebook (man, there’s a lot of mushroom people out there), which generated more comments (64!) than any other thing I ever posted, and people with a lot more mycological education than I chimed in with some really great input. My favorite, from Kathie Hodge of Cornell University (there’s a link to her blog on the left), was a link to the Biodiversity Heritage Library, which is digitizing hundreds of thousands of works of “legacy literature” (old research books) from natural history and botanical libraries all over the world, and you can just read them, right there online! And she steered me to a book, Researches on Fungi,  by A. H. Reginald Buller, written in 1934, with one chapter titled “Puffing in the Discomycetes” (which are now called “Ascomycetes”—see here), and another titled “The Sound Made by Fungus Guns”!!!   First he thinks he heard it, while puttering around in his lab while there was a specimen on the table, then he applies himself like a rat terrier to seeing if he can hear it again: lying next to them in the woods, holding fungi to his ear and finding “…when it puffs one can not only hear the sound of the puffing but also feel the spray from the asci as though the ears were being sprayed with a fine atomiser.” A man after my own heart! It’s really charming reading. But, I think I would draw the line at letting a mushroom spray spores into my ear. I think.

He wrote really great explanations of the mechanics of all this, which I didn’t have the patience to read. Maybe if I had the actual printed matter in my hands I’d read it. I’m just happy to know that some mushrooms make hissing sounds when you blow on them.

To help you calm down after all that excitement, here’s a few more images of Urnula craterium.

(Some of us think the smaller ones in the photo above are a different species, and I finally got a real live mycologist to confirm it--probably Pseudoplectania.)

I've never seen any mention of these taking on the same color as the surface of the wood they're growing on, but it seems to happen fairly consistently.

Anyway, I’m just trying to tell you that some mushrooms make noise. Not all mushrooms release their spores in such an extravagant fashion, but these do. I feel lucky to have witnessed it. Now you can, too!

Sprouting acorns—who knew?

I’ve been stalling on this post for quite a while, wanting to give it special attention, because I was so struck by these. Couldn’t decide which images to use, in what order--real hand-wringing!

I was wandering around in the woods as usual, in mid-April, looking for things (mushrooms, if possible), and I noticed all these RED things on the ground, deep red spots all over the place. At first I just thought it was some leftover pieces of acorns, I don’t know, changing colors like a piece of fading fruit, until I got my face down closer, and found yet another whole new thing going on.

These look innocent enough, except for that startling red

I don’t know what I thought about how acorns sprouted in the woods, but it certainly wasn’t this! I guess I thought a bunch of nice pale brown acorns fell, most were eaten, and a few sprouted like any other run-of-the-mill seed. What surprised me were the colors (many), and the shapes (as usual). Also, there were a lot of them. Every several inches there was another one! I took precisely one million pictures, then kicked myself later (only a little) for not taking more, and for not spending just a little more time getting better shots…tricky to get everything in focus with shoots up there and acorn down there…       

Sprouting acorns-23

I wonder what those tiny white spots are (above). Nice touch!

Then I started to run into stuff like this:
Sprouting acorns-46

Okay, here is when I began to realize things were getting a little out of hand. Which is the shoot and where is the root, and what are those sea-slug-like-like ruffles? And everything’s all tangled up and wild colors!

wavy cotyledon

The wiggly red things are not the first leaves! They’re connected to the cotyledons. The shoot with the first true leaves is between the two flat wiggly things.

Why is everything red?

Sprouting acorns-36

I actually had to stop and look at this for a while. If that’s the leaf/shoot sticking straight up, then what’s all that other stuff? I had to discuss it with a friend, who helped me untangle the structure.

Sprouting acorns-49

This one (above) is waving one cotyledon in the air.

As near as I can figure, with acorns (at least this model) everything happens at once. Maybe since it’s got so much food available from the big fat nut meat (and it needs to move fast before someone eats it), it puts out a root and shoot with true leaves at the same time, ready to go, all the while taking sustenance from the big acorn nut (the cotyledon, which is like a placenta, really), so it’s all just *blam!*, get everything going all at once! It’s pretty much like any other seed sprouting, but the cotyledons are extra large, and they seem to not have to leave the shell for everything to work out.

The term “cotyledon” was coined by 17th-century physician Marcello Malphigi (“bad piggy”).

But, the operating words here are “as near as I can figure.” I don’t know any acorn experts yet.

A few more:

Sprouting acorns-52

See, the shoot is already up, and those red arms are attached to the cotyledons, still in the shell.

Lastly:

Sprouting acorns-53

Take that, Georgia O’Keeffe! Kids, go ask your parents what that means.

So you walk around thinking you have a basic idea of what’s going on out there, until you look closer. Well, good luck with that! Look where that got me.

More forest offerings, spring 2011 (almost everything up to late April)

After these there’s still a few more installments coming, of things that deserve their own posts, before I’m current. In the meantime here’s even more of the late leftovers. I can’t help it if there’s so much going on out there!

Here’s this year’s Virginia bluebell buds:
Virginia bluebell
I tell you, I can’t stand it. The buds are this other-worldly opal/purple color, in that great unexpected shape, and then the flowers open very nonchalantly in a completely different color. But it’s the bud shapes that really get me.

Here’s some Goldenseal (Hydrastis canadensis). First time I’ve seen it. Then, of course, I started to see it everywhere.
Goldenseal (2)

Oh, and check this out:
Goldenseal
Blooming even before the leaves are unfurled!

Here is a Gray Tree frog (Hyla versicolor).
Gray tree frog
Or it could be Cope’s Gray tree frog, H. chrysoscelis, but you can’t tell them apart in the field (well, their calls are a little different), but H. versicolor has an extra set of chromosomes! So they sometimes call it Tetraploid Tree frog! But never mind that, they can camouflage themselves, like chameleons (but slower)! I’d like to see that, but I think I was pretty lucky to get this close at all.

From a little distance I thought it was a lump of woody polypore or something, on a dead tree. I walked up to see it and it was a frog instead. I actually got this close (this isn’t a zoom shot), through sneaking.
He finally broke, and jumped away, which is when I discovered the yellow on his hind legs:
gray tree frog yellow foot
Yet another thing I had no idea about.

Here’s a tiny little snake I also sneaked up on:
Tiny snake

No, I mean tiny, he was barely as thick as a pencil--

tiny snake with finger
Storeria dekayi
He saw me first, and started to go away (made noise in leaves, gave himself away) but then slowed and stopped, so I began my sneaking. I don’t know why he let me get this close.
Its common name is "brown snake." Just "brown snake." Or "Midland brown snake," or "Dekay's brown snake." They don't get much longer than 12", and they eat mostly worms, and slugs, snails and soft-bodied insects. I know from his round pupils that he is not venomous (at least, that rule works in Missouri, barring someone's venomous pet snake having escaped). Here I confess that I did not know until recently that there are several tiny Missouri snakes, just because they're small doesn't mean they're babies.

One last thing. I keep finding may apples that have grown through a hole in a dead leaf as they emerge in spring, and they get pretty tall with this leaf stuck around them:

And yes, of course I free them by taking the leaf off, but not before I take a look at this:
