Creepy blob of resin on a tree

While searching for yellow brain fungus on a hot day in December, I stumbled across this twisted little blob of gunk nestled in a bark crevice. At first I was all excited that it might be some sort of snow fungus (e.g., Tremella fuciformis) that was past its prime, but I’m pretty sure it’s just resin, gum, or sap — not sure which. But I’ve never seen resin with little spheres blebbing out, and nothing with a white membrane. It’s creepy. If you have more information or have wild speculation, please send me a note or leave a comment. Approximately 1″ long. Photographed at Lake Mohonk, New Paltz, New York.

I really had wanted this to be a slime mold … perhaps an immature Trichia or Stemonitis. If you’re a slime mold fan, please weigh in.

Sweet potato latex

Here’s a fun trick for Thanksgiving. If you get into an argument about whether you purchased yams or sweet potatoes at the store, chop one in half before cooking and look for milky white sap bleeding off the flesh. Only sweet potatoes do that. But if you don’t see sap, that might mean you just have an old sweet potato, so don’t place large bets when doing this. More useless trivia at “Yams versus sweet potatoes“.
