Ghost Pipe

I learned something new! I love it when that happens.

In the last few months I moved from just below to Fall Line to deep in the Piedmont.  As a result the collection of counties I am responsible for have gotten hillier, wetter, and slightly cooler.  I’m seeing a different suite of flora and fauna than before, including some things that haven’t previously been on my radar.

A bowshot from National Forest land in the high hills of North Georgia, something caught my eye beneath the white pines, oaks, beeches, and maples.  Small white stalks rose from the leaf litter, curling over at the top with a petaled capsule like a lamp post for gnomes.  I snapped some photos so I could look up what kind of fungus this was when I got home. 

Monotropa uniflora is known by several common names, including ghost plant, Indian pipe, ghost pipe, or corpse plant. It was much more interesting than I gave it credit for.  For starters, it isn’t a fungus; it’s a plant in the heather family.  Instead of spraying spores to reproduce,  ghost pipe requires native bees to visit its flower and carry its pollen. Unlike heather (and most plants), ghost pipe doesn’t produce chlorophyll, so it can’t use sunlight to make energy.  So how does it live?

That’s the next interesting bit.  There are many fungi that engage in mutualistic association with plants.  These fungi, known as mycorrhizae, colonize the roots of plants. They assist the plant in collecting water or nutrients, and collect carbohydrates created in the plant’s chlorophyll factories above.  The ghost pipe is a parasite of certain mycorrhizal fungi.  This is a switch; usually a fungus parasitizes plants.  But we have a plant stealing sugar from a fungus that said fungus “traded” from a tree that produced that energy in the sunlit canopy 80 feet above. Thus, it can grow in the densest, darkest forests.  Ghost pipe pops quickly up after a rain, and flowers in early summer to autumn; I was fortunate to have wandered the woods at just the right time to see them.

Curiosity is an important trait for any aspiring naturalist.  Knowledge can be gained by seeking answers, but curiosity is the driver.

Encounter With a Shrew

I have a brief encounter I’d like to relate.

I’d just finished a meeting on the northern edge of the state, and I wasn’t entirely ready to head to lower lands.  So I found a pull-off where I could park the truck and ambled down next to the river.  Here the water was deep enough to roll on fairly smoothly, but only lightly clouded compared to the brown waters a few counties south.  I sat here for a few minutes, trying to be present – my mind pushing away the people I’d dealt with earlier and the long drive ahead of me.  Off in the distance rose the high, thin whine of Brood X cicadas.  By my knee, an adult dobsonfly, another short-lived but far quieter insect, twined around a grass stalk.

It’s not hard to lose track of time beside running water, but home called so I didn’t tarry too long.  Back up to the roadside, I paused to take one more look at the river.  I don’t recall hearing anything noteworthy, but my eyes flashed down to the ground.  There, beside my boot, a shrew about the size of my thumb lunged out from under a leaf to grab an earthworm by the middle.  The tiny insectivore backed into the leaf litter with its thrashing prey.  I knelt and flipped over the leaf, revealing a tunnel of sorts in the humus; the shrew was already away to eat and resume its neverending hunt. 

My meetings with shrews are rare enough to make this close encounter notable. I wouldn’t want to handle a shrew, of course, as they are among the only venomous mammals.  A nip from one of these fellers would cause localized pain and swelling for a few days, but their toxic saliva renders worms, insects, and even mice paralyzed and comatose.  Shrews store their captured prey in caches for later use.  Given their high metabolic rate – starving in a matter of hours if not fed – storing ready food is not a bad strategy.

This is a common theme with me, but one which I hope will sink in. Take the time to stop, to be still, to look and listen.  How can Nature grace you with a moment if you aren’t there to appreciate it?
