Eight of Pentacles

The Eight of Pentacles is the apprentice at his bench, hammering the same star into coin after coin. Six are done and hanging on the wall. He's working on the seventh. It's the card of craft, practice, diligence, and doing one thing well until it's yours.

The Laboulbeniales are the quiet craftsmen of the fungal kingdom. They're tiny. A single fungus is a stalk and a few cells, often less than a millimeter tall, standing on the shell of a beetle, a fly, a mite, or an ant like a sculpture on a plinth. They don't make webs of threads, and they rarely kill their hosts outright. Most of them just stay where they landed, attached to the hard cuticle and, in many species, fed through a small root that goes into the host. Since they can't survive off the host, they spread by contact. For species that live on beetles, contact often means mating. That can make them strikingly specific. Some grow only on one host species, some only on one sex of it, and some only on one exact part of the body, the part that touches a partner during mating.

The first person to take them seriously was Roland Thaxter, a Harvard mycologist who spent some four decades describing and drawing more than a thousand species, each one a few hundred microns tall, in beautiful detail. Researchers are still finding new ones, often by looking at old insect collections in museum drawers.

This is the card of the craft that's too small for anyone else to notice. The opportunity of the Eight is mastery through narrowness. Doing one thing, for one host, in one exact place, is how you become irreplaceable. The Laboulbeniales have been at it for a very long time. The risk is that specialization is also a restriction. The fungus can't leave its beetle. Ask whether your craft is a practice you've chosen, or a segment of shell you can no longer climb down from. And ask who, in your life, is Thaxter: the one who sat at the microscope and saw the tiny work you were doing.
