Some photographs of Armillaria (honey mushroom) underneath the bark of a dead tree. The rhizomorphs look like plant roots but they are filled with hyphae, which sometimes emerge in a more classical mycelial fan. If you find these in your backyard, look for bioluminescence on a cloudy, moonless night. Just give your eyes about 20 minutes to acclimate.
Here’s the fruiting body, photographed at a different location:
Here’s a gooey, mysterious find from my trip to Mohonk Mountain House over Thanksgiving.
It took me a while to identify, but it’s a stalked puffball-in-aspic (Calostoma cinnabarinum), an ectomycorrhizal boletes that is associated with oak tree roots. It has a number of amusing common names such as hot lips and pretty lips. This one was growing around a pine tree, so perhaps they are flexible about their symbiotic partner. It’s also possible that roots from distant oaks extended to this location (there are some leaves in the frame). But I think the former is more likely, partly because I found a paper (Bautista-Nava and Moreno-Fuentes 2009) that says they grow in pine forests in Mexico. But that paper is in Spanish, which I cannot read, so I could have that wrong.
Found this clump of fluff a few days ago and initially wasn’t sure what it was. I’d assumed it was some sort of a gall, but when displayed on a big monitor I could see there were legs sticking out. Pretty sure it’s a spider parasitized by a cordyceps fungus. I’m guessing Torrubiella leiopus. But if I’m wrong about it being a spider underneath, I’ll retract that guess. Sort of looks like Sideshow Bob on The Simpsons.
