AGARICUS VIRGINEUS, Wullf.
Subgenus 8. Clitocybe. Subdivision Camarophylli.
White Field-Agaric.
Bot. Char. Pileus from one to two inches broad, margin involute when young, then expanded, depressed in the centre. Gills deep, connected with veins, sometimes forked, broadly adnate, but breaking away from the stem as the pileus becomes depressed. Stem six lines broad at the top, tapering downwards, not more than two at the base; at first stuffed with fibres, then hollow, excentric; the whole plant white, with occasionally a tinge of pink. Taste pleasant, odour disagreeable.
These graceful little Agarics grow in pastures, and are extremely common in the autumn. They are so small that it requires a great many of them to make a dish, but as they occur frequently in the same fields with puff-balls, and may be dressed in the same manner, it is not unusual when the supply is scarce to serve them together, with the same sauce. The flavour of Ag. virgineus is not unlike that of Ag. oreades.
TUBER ÆSTIVUM, Vitt.
Peridium warty, of a blackish-brown colour, the warts polygonal and striate, flesh traversed by numerous veins; asci 4-6-spored; spores elliptical, reticulated.
This plant, the common truffle of our markets, is abundant in Wiltshire and some other parts of England, and probably occurs in many places where it escapes observation, from its subterranean habit.
