[R] Specimens of this mould were distributed in Cooke's "Fungi Britannici Exsiccati," No. 356, under the name of _Clinotrichum lanosum_. [S] Cooke's "Handbook of British Fungi," p. 602. [T] Cooke's "Fungi Britannici Exsiccati," No. 329, under the name of _Sporidesmium polymorphum_ var. _chartarum_. [U] This reminds one of Preuss's _Alternaria_, figured in Sturm's "Flora;" it has been suggested that the mould, as seen when examined under a power of 320 diam., is very much like a _Macrosporium_. Again arises the question of the strings of spores attached end to end. [V] "Handbook of British Fungi," vol. ii. p. 926, No. 2,788. XII. CULTIVATION. The cultivation of fungi in this country for esculent purposes is confined to a single species, and yet there is no reason why, by a series of well-conducted experiments, means should not be devised for the cultivation of others, for instance, _Marasmius orcades_, and the morel. Efforts have been made on the Continent for the cultivation of truffles, but the success has hitherto been somewhat doubtful. For the growth of the common mushroom, very little trouble and care is required, and moderate success is certain. A friend of ours some years since was fortunate enough to have one or two specimens of the large puff-ball, _Lycoperdon giganteum_, growing in his garden. Knowing its value, and being particularly fond of it when fried for breakfast, he was anxious to secure its permanence. The spot on which the specimens appeared was marked off and guarded, so that it was never desecrated by the spade, and the soil remained consequently undisturbed. Year after year, so long as he resided on the premises, he counted upon and gathered several specimens of the puff-ball, the mycelium continuing to produce them year after year. All parings, fragments, &c., not utilized of the specimens eaten were cast on this spot to rot, so that some of the elements might be returned to the soil. This was not true cultivation perhaps, as the fungus had first established itself, but it was preservation, and had its reward. It must be admitted, however, that the size and number of specimens diminished gradually, probably from exhaustion of the soil. This fungus, though strong, is much approved by many palates, and its cultivation might be attempted.
