Field Notes

Description:

The cord, which is called a "funiculus" in Mycologese, is the egg's mechanism for attaching itself to sticks, leaves, and other plant debris. When a raindrop falls into the nest, the eggs are projected out of the cup. As this happens, the cord is stretched to its limit--then breaks away from the nest, remaining attached to the egg. Where the cord was attached to the nest, it becomes frayed, since it was torn away. The little frayed ends are adhesive, and when they come into contact with, for example, a leaf, they attach themselves. This stops the flight of the egg, which then swings back and attaches itself to the leaf as well . . . rather like what would happen to a kite if you were to let it sail away after coating your end of the string with glue ( http://www.mushroomexpert.com/crucibulum_laeve.html ). ---- good to see at picture #3

then, you have very sharp eagle eyes :) . i found them accidentally: was looking for bigger-sized ones, and bowed down. When i wanted to stand up again, i look at the ground near my feet and saw just a weird shape, which i freed from a litter-cover. ( but to be honest i knew at this park had i found already some before last year, but different park-areas/different mycelium-colony! ), they where all on little branches. !
thanks laura, nothing stops you! you would suprised in which little places with few tree i found the nicest spottings. This one is from some kind of city-park. Fungi are everywhere, you just have to look closely. :)
Beautiful little fungi, Alex :) Great photos! You make me wish I lived closer to a forest, so I could go out and find all kinds of amazing fungi!
