This soft fungus bears a distant resemblance to some species of Clavaria. It is uncommon, grows upon the ground, and possesses a very disagreeable odour. =Olive-gilled Mushroom.= Fig. 5. (_Agaricus_ [_Hypholoma_] _sublateritius._) 328. This plant is allied to fig. 1, and, like it, grows upon old stumps in woods, and has, too, a disagreeable smell. =Astringent Mushroom.= Fig. 6. (_Panus stypticus._) 582. Is very common on old dead trees and stumps in woods, and had better be avoided. =Matrix-bearing Mushroom.= Fig. 7. (_Agaricus_ [_Amanita_] _Phalloides._) 2. Common everywhere in woods; this handsome Agaric is known to be highly dangerous. It is allied to fig. 8, as will be seen by glancing at the figures. All parts are nearly white, excepting the top, which generally takes some pale shade of subdued yellow or green. =Poisonous Spring Mushroom.= Fig. 8. (_Agaricus_ [_Amanita_] _vernus._) 1. Belonging to a very suspicious group, this Agaric is supposed to be very poisonous. It grows in woods, _in the spring_, and is white in all its parts. It is rare, but I have found it close to London. =Magpie Mushroom.= Fig. 9. (_Coprinus picaceus._) 379. This, too, is equally rare, though in some places, as in the Herefordshire woods, it is by no means infrequent. It is a very handsome but suspicious-looking plant, with the top broken up into large patches of black and white. It grows on roadsides, and has a disagreeable odour. =Gloomy Tube-Mushroom.= Fig. 10. (_Boletus luridus._) 607. This is one of the handsomest ornaments of our woods and woody places. The prevailing tint is umber, relieved on the under surface by bright red, sometimes approaching crimson, or even vermilion; when broken or bruised it rapidly changes colour to blue. It is very common in all places where there are trees, and often comes up early in the year. It is probably more or less poisonous, though I have known it to be eaten without _fatal_ effects. Mr. Penrose once found a specimen as large as a milking-stool, exactly three feet in circumference. =Griping Milk-Mushroom.= Fig. 11. (_Lactarius torminosus._) 488. This dangerous fungus is at once known by the hairy margin of the top, which is rolled inwards. The milk that exudes when the plant is broken is acrid and biting, and does not change colour as does fig. 11, Edible Sheet, and figs. 20 and 28, Poisonous Sheet. Though said to be common, I think it is somewhat rare; it now and then occurs in solitary specimens in the woods and open places near London. =Ruddy Milk-Mushroom.= Fig. 12. (_Lactarius rufus._) 512.
