Another pair of Gautieria

that I found in June of this year were a perfect example of this. One was mature, the other not. The odor of the mature specimen was so overwhelming that I couldn’t keep it in the frig, even wrapped in waxed paper. The other had mild odor, that was not unpleasant.

The late Welles Bushnell collected Gautieria from Yellowstone that almost drove him from the car. He had put it in the trunk. The smell of fresh asphalt forced him to the side of the road for ventilzation! If you remember the big Yellowstone fire a few years ago, you remember when he collected it. Heat really brings out the asphalt aroma.

I find Gautieria monticola occasionally. The aroma can be asphalt, roofing tar, none, or overpowering. In the same collection. Maturity of specimens has so much to do with aroma.

Thank you Daniel.

The odor was actually subtle, sweet, earthy and maybe a little spicy. Pleasant. Not strong, and chemically, but I know a subtle odor can become powerful with maturity.

Good find!

Mature Gautieria often have strong chemical aromas, Mike. Did you notice any odor?

Identification made mostly by cinnamon-colored gleba, cartilaginous sterile veins, close locules, mountanous habitat. There are several Gautieria endemic to California at higher elevations. I’d wait to get this under a microscope to check spore size/color/ridges before saying for sure.
