![very late, but a group of which A. gamhoms, Fr., is the type, is strictly vernal, and the species constituting it have long been con- sidered special delicacies ; the greater number of the remaining species are also edible, and have a pleasant odour like that of new flour, but a few are rank and suspicious, of which A. saponaceus, Fr., is an example. This veiy large subgenus has been subdivided by Fries in the following manner:—1. Pileus viscid. 3. Pileus floccu- lose. 3. Pileus rigid. 4. Pileus silky. 5. Pileus spotted or mi- nutely cracked. 6. Pileus spongy. 7. Pileus hygrophanous. In Hygj-ophoriis, Lactarins, and Rnssnla, the general structure is much the same as in Tricholoma, but they form well-marked genera. Hy- grophorus is distinguished by its wax^ nature; Lactarins by its milJc]/ gills and flesh ; and Rimitla, by its rigid brittlg gills generally in one series and vesiculose flesh. The species figured is Agarieus (Tricho- loma) terreus, Schseff. Spores -0002 X -00013. Subgenus 5. Cmtocybe, Fr. Syst. Myc. vol. i. p. 78 (Plate I. fig. 5).—Pileus, generally fleshy in the disk, obtuse, plane or depressed, hjrgrophanous or not hygrophanous; stem confluent and homogeneous with the hymenophorum, elastic, with an outer coat, covered with minute fibres; gills acutely adnate, or decurrent. The fibrillose outej coa^ of Clitocyhe (and sometimes of Tricholoma and Fhurotus) must not be confounded with the truly fibrous bark of Collybia, Mycena, Omphalia, and their analogues.—Hab. All are terrestrial. Clitocyhe corresponds with Clitopilits, Plate II. fig. 14, and Flam- mula, Plate III. fig. 21. The species are generally small, though some are very large; many possess an agreeable odour, but few only are known to be edible. Most of the species appear late in the autumn or in early winter. In Cantharellus the gills are strongly decurrent, but they are reduced to thick veins or folds. The species of Hygro- phori, with decurrent gills, can be easily separated from Clitocyhe, by their waxy nature; and Lepisla is known by the decui-rent gills separating from the hymenophorum. The species figured is Agarieus (Clitocyhe) yeotrupus, Bull. Spores '00028 X'0002, they sometimes have a slight tendency to become echinate; spines are greatly deve- loped in the var. suhinvolutus, Batsch, a single spore of which is shown at J. Subgenus 6. Pleurotus, Fr. Epicr. p. 129 (Plate I. fig. 6).— Veil evanescent, or none; pileus fleshy in the larger species, with a](https://iiif.wellcomecollection.org/image/b22277602_0016.jp2/full/800%2C/0/default.jpg)
