=Boletinus pictus= Pk.--This very beautiful plant is quite common in damp pine woods. It is easily recognized by the reddish cottony layer of mycelium threads which cover the entire plant when young, and form a veil which covers the gills at this time. As the plant expands the reddish outer layer is torn into scales of the same color, showing the yellowish, or pinkish, flesh beneath, and the flesh often changes to pink or reddish where wounded. The tubes are first pale yellow, but become darker in age, often changing to pinkish, with a brown tinge where bruised. The stem is solid, and is thus different from a closely related species, _B. cavipes_ Kalchb. The stem is covered with a coat like that on the pileus and is similarly colored, though often paler. The spores are ochraceous, 15--18 × 6--8 µ. The plants are 5--8 cm. high, the caps 5--8 cm. broad, and the stems 6--12 mm. in thickness. Figure 175 is from plants collected in the Blue Ridge mountains, Blowing Rock, N. C., September, 1899. =Boletinus porosus= (Berk.) Pk.--This very interesting species is widely distributed in the Eastern United States. It resembles a _Polyporus_, though it is very soft like a _Boletus_, but quite tenacious. The plants are dull reddish-brown, viscid when moist, and shining. The cap is more or less irregular and the stem eccentric, the cap being sometimes more or less lobed. The plants are 4--6 cm. high, the cap 5--12 cm. broad, and the short stem 8--12 mm. in thickness. It occurs in damp ground in woods. The =pileus= is fleshy, thick at the middle, and thin at the margin. The =tubes= are arranged in prominently radiating rows, the partitions often running radiately in the form of lamellæ, certain ones of them being more prominent than others as shown in Fig. 176. These branch and are connected by cross partitions of less prominence. This character of the hymenium led Berkeley to place the plant in the genus _Paxillus_, with which it does not seem to be so closely related as with the genus _Boletus_. The stratum of tubes, though very soft, is very tenacious, and does not separate from the flesh of the pileus, thus resembling certain species of _Polyporus_. Figure 176 is from plants collected at Ithaca. [Illustration: PLATE 63, FIGURE 176.--Boletinus porosus. Viscid when moist, dull reddish brown (natural size). Copyright.] =Strobilomyces strobilaceus= Berk. =Edible.=--This plant has a peculiar name, both the genus and the species referring to the cone-like appearance of the cap with its coarse, crowded, dark brown scales, bearing a fancied resemblance to a pine cone. It is very easily distinguished from other species of _Boletus_ because of this character of the cap. The plant has a very wide distribution though it is not usually very common. The plant is 8--14 cm. high, the cap 5--10 cm. broad, and the stem 1--2 cm. in thickness.
