One of the most time-honored pieces of advice is the admonition "don't sweat the small stuff," as well as the corollary, from the title of the bestselling self-help book by Richard Carlson, "... and it's all small stuff." That's certainly good advice for stress reduction, but when it comes to natural history, not sweating the small stuff is precisely the wrong way to go. Case in point: had I overlooked this particularly "small stuff," I'd have missed an always fascinating encounter with one of the more magical mushrooms in existence. Bird's Nest Fungi, which get their common name for obvious reasons, are mini-wonders whose "eggs" are, in fact, spore containers that often crack open due to the pounding of rain drops and splash spores everywhere, thus spreading the various species to new neighborhoods. Each "nest" is about the size of a little fingernail and, clearly, the very definition of small stuff—small stuff definitely worth sweating. And enjoying.
