The bark, the wood, have other deputed powers of destruction, many of which are very beautifully fabricated. To dwell on them would extend too much these remarks, designed rather as observations than details; yet I am tempted to introduce two. The sphæria coryli of Lamarck (peziza coryli) is occasionally to be found in the month of January, and through the winter until April, upon old hazel sticks, and engages our attention by the regularity of its tubercles. The seed, or first principle of production, whatever this may be, by means unknown to us, has been fixed upon the inner bark of the wood. Gently increasing, it bursts its way through the outer bark, which now hangs as a fringe about it; the seed vessels expand, and a dusty substance, being most probably the matter that continues the species, is dispersed around. A singular plant (sphæria faginea?) is found upon the decayed wood of the beech-tree,[35] in the earlier part of the spring. It appears on the surface of it in little nodules, which, gradually uniting and increasing, form a regular black crust. Upon examination we find, that little round bodies have forced a passage through the outer bark, and enlarged into small round tubes, which ultimately become the conductors of the seminal dust, discharged from round, beaked seed vessels, embedded beneath upon the inner bark. This plant presents us with a very remarkable instance of the attention of nature to the preservation of minute and little observed things; the protection of the seed vessel, and the dissemination, being most particularly and carefully provided for. These specimens are only individuals among hundreds, which present us with a world of beauty, variety, and wonder. I would not wish it to be understood that it is maintained, by any thing here intimated, that the dissolution of vegetable matter is effected solely by the agency of insects or parasitic plants, Nature having various ways of accomplishing her purposes; but only mean to contend that, in numerous cases, these weak instruments are made use of to accelerate the decay and dispersion of it. We are not favorably circumstanced for any great abundance of the race of fungi: the old fir grove—which produces such varieties, and the oak and birch copses, which have shed their leaves for ages, and given rise to many, are not found with us; yet we have a small scattering too, some of which are perhaps not undeserving of notice; and, though rather partial to a class which has afforded me many hours of gratification and delight, yet, sensible of the little interest they generally create, I must limit my mention to a very few.
