According to Paulet, Persoon, and Vittadini, the _Hyd. repandum_ should be cooked for a long time, and with plenty of sauce, otherwise, being deficient in moisture, it is apt to become rather tough; when well stewed it is an excellent dish, with a slight flavour of oysters; it makes also a very good _purée_. Vittadini places it among the most delicate of the funguses of Italy. FISTULINA HEPATICA, _Fries_. PLATE XII. FIGS. 1 AND 2. “Fungus pauperibus esculentus.”—_Schœff._ This fungus, which, in the earlier stages of its development, frequently resembles very closely a tongue in shape, structure, and general appearance, presents later a dark, amorphous, grumous-looking mass, bearing a still more striking likeness to liver. Thus, seen while young, and just beginning to bud out from the oak,[181] its papillated surface, regular shape, and clear fibrous flesh make it an object of interest to many who, introduced to it at an advanced period of growth, can hardly be brought to believe that the blackened misshapen mass, that looks like liver, and that deeply stains the fingers with an unsightly red fluid, can indeed be the same plant. It has, from the earliest-recorded accounts, been designated by names pointing to these resemblances: Cesalpinus calls it _Linguæ_; Wallemb, _Buglossus quercinus_; the vulgar name in Italy is “Lingua quercina,” or “Lingua di castagna.” It constitutes a genus by itself. _Bot. Char._ _Pileus_ confluent with the stalk: at first studded on the upper side with minute papillæ (the rudiments of tubes), which afterwards disappear; flesh succulent, fibrous, like beetroot in appearance, with a vinous smell and a slight acid taste; _tubes_ continuous with the fibres of the receptacle, unequal, very short, small, cylindrical, ochraceous-rufescent; at first with closed pores, but as they elongate they become patent; colour at first a dry dusky white, afterwards a yellowish-red; the whole surface more or less sticky, with a gelatinous secretion exuding from it; _sporidia_ ochraceous-green, and matured at different times from the unequal length of the tubes. This fungus varies in size from that of a small kidney to an irregular mass of many pounds’ weight, and of several feet in circumference. I recently picked a specimen which measured nearly five feet round, and weighed upwards of eight pounds; but this is nothing to one found by Mr. Graves, which, on the authority of Mr. Berkeley, weighed nearly thirty pounds.
