We cannot recollect having ever before seen all kinds of fungi so plentiful as they are throughout Lochaber this season. You meet mushrooms of all sizes and of all shapes, both edible and poisonous; while fairy rings are so common that you may encounter one or more of them in every bit of old pasture and in every greenwood glade. One of these rings we had the curiosity to measure a few days ago, and we found its diameter to be precisely fifteen feet, giving it a circumference of upwards of fifty feet, as nearly as possible a a perfect circle, the emerald outline, studded with its peculiar pretty white, button-like Agaraci, amid the lighter green of the surrounding herbage, as distinct and easily traceable, even at several hundred yards distance, as ever was halo round the moon. We noticed that a cow, happening to come the way while we were examining another of these fairy rings, ate them all with evident relish, browsing so steadily along and around, that when she completed the circle she had not left a single one. We hope that they agreed with her, though we should not like to have joined in the repast, for we have a salutary horror of the whole mushroom tribe. The so-called edible mushroom is said to be delicious when properly cooked: should it ever in any form be a dish on a table at which we are seated, we promise to give our share of it, totus, teres atque rotundus, whole and unimpaired, to the first that will accept it. To the present intense heat, coming so suddenly on the back of long-continued rains, is probably due the extraordinary abundance of all kinds of fungi.
