Eyelash cup Scutellinia scutellata

This little cup fungus is your reward for laying on the damp ground to look at stuff. Tiny orange discs fringed with little dark hairs--how magical! What on earth are the "eyelashes" for? Are they a protective barrier against very very small grazing animals?

This fruiting body appears on wood that is so decayed that it almost isn't wood any more. This group appeared on the stump in our front yard that produced these oyster mushrooms.

Urban species #295: Eyelash cup Scutellinia scutellata

There are many species of cup fungi. The fruiting bodies of these fungi are more or less round and usually rubbery, forming discs or bowls depending on their concavity. Unlike more familiar umbrella or shelf mushrooms, which produce spores on their undersides, cup fungi produce spores on the top surface of the fruiting body. The spores are protected in microscopic sacs that have aperatures at the cup surface. When the conditions are right, a tiny cap springs off the aperature, and the spores are forcibly ejected into the air. Eyelash cups are very small, seldom as big as a centimeter in diameter. When examined closely, they reveal an interesting feature: the edge of the cup is ringed with miniscule black hairs. Eyelash cups can be found anywhere there is well-decayed wood.
