Macrotyphula juncea

…and a thank you to Randal Mindell of UBC Botanical Garden, who wrote today’s entry:

If anyone is wondering what the term gregarious means in a mycological context, Daniel’s photographs today do a fairly good job of illustrating it. Macrotyphula juncea is a relatively widespread, yet under-reported fungus, documented across both hemispheres at diverse longitudinal gradients. According to David Aurora’s Mushrooms Demystified, it is typically found on decaying leaf litter. Here in the garden, we found it atop maple leaves in late October.

This genus falls within the fungal phylum Basidiomycota, better known as the mushrooms. While Macrotyphula juncea does not look like a typical mushroom, what you are seeing in the corresponding photographs are above-ground “fruiting bodies” that bear the same characteristic spore-bearing structures (basidia) as all members of the phylum. The solitary, thread-like fruiting bodies of this species are less than a millimeter in diameter and are observed in our massive population to approach 10 centimeters in height. While their surfaces appear remarkably smooth to the naked eye, under the microscope, you can see that it is entirely covered by spore-bearing basidia.

Can you eat it? In David Aurora’s infamous Mushrooms Demystified, the edibility of Macrotyphula juncea is described by the author as “utterly irrelevant–a couple hundred would be needed for a mouthful!”.

    Wow! I have seen this in the Smokies! It was in a small pool of water overlaying leaf litter.

    After looking at the titles, as I scrolled down, I looked at the specific epithet for clues. Thought it might look like Juncus. I checked the family name – no help. And then the picture – still no idea what I’m looking at. But a mushroom. What fun!

    he…he…yep the

    does kinda looks like a juncus to me … enough to justify the name anyway. Is that why it was so named?

    I think so, yes.
    There’s one little factoid I meant to add as one of the first comments. Gather a bunch of them in your hand, make sure they’re in a pile, and inhale… the scent of apple pie!

    Interesting little fungus.
    Also a bit scary like needles. But if it smells like apple pie then it’s good stuff.

    Wow. At first, it looked like a 3D seismograph . . . or a collage of the EKGs of a team of lugers!
