CRYPTOGAMIA. FUNGI. Boletus. 
Schaeff. 122. 
Tubes decurrent, very short, white, semi-transparent. Pores white, minute, 
angular.* 
Pileus rich brown, scaly, hollow in the middle, turned down at the edge, two 
inches over. 
Stem whitish, its upper part covered with tubular pores, rather conical, half 
an inch long, and as much in diameter. 
Schaeffer in plate 121, has figured another plant with a smooth pileus, 
which he thinks is the same, and calls them both B. ovinus. On account 
of the uncertainty of their identity, I have thought it better to give, it a 
new name; to say nothing of the futility of the old one. This species is 
subject to be over-run by the white and the yellow Reticularia of JBul- 
liard. Schaeffer’s plate 121 is cited by Hudson as B. subiomentosus of 
Linnaeus, which see. 
(Pellucid Boletus. E.) Pool dam, Edgbaston. 6th Aug. 1791. 
Bol. suBPUs f cus. (Schaeff.) Tubes white, very short: pileus light 
brown, regularly convex: stem pale brown: root conical. 
Schaeff. 130, may serve to give some idea of it, though it is not the plant. 
Tubes white, quarter of an inch in length, pretty firmly fixed to the pileus. 
Pores white or brownish white, very minute. 
Pileus light brown, smooth, uniform, clothy to the touch, convex, four or 
five inches over. Flesh very white. 
Stem pale brown, covered with a beautiful white net-work over its whole 
surface, three inches high, and two inches diameter. Root conical. 
Much like Bol. elepliantinus in its habit, but differs in the colour of its 
tubes, stem, and pileus, as well as in the form of the latter. No part of it 
changes colour on exposure to the air. 
(Brown Reticulated Boletus. E.) Edgbaston park, under the large 
oak near the wall of the square stew. Sept. 
Bol. cyanes'cens. Tubes white, brownish with age: pileus brown, 
convex, very fleshy: stem brown, rounded at the base. 
Bull. 369. 
Tubes dirty white, quarter of an inch long, not decurrent. Pores small, 
nearly all alike. 
Pileus brown, convex, very fleshy, from five to eight inches over. Flesh 
white, changing to fine blue when exposed to the air. 
Stem brown below, white above ; two to three inches high, one and a half to 
near two inches diameter, cylindrical upwards, the lower part rounded 
and egg-shaped. Bull. 
(Cyanean Brown Boletus. E.) Observed by Dr. Sibthorpe in the walks 
of Magdalen College, Oxford. Sept. 
Bol. polypo'rus. Tubes white and very short: pileus brown, irre¬ 
gular : flesh very thin : stem brown, rarely central. 
Bull. 469. 
♦ The pom are the open ends of the tubes which present themselves to the eye upon 
turning up the pileus, previous to any dissection of the plant. These apertures are 
sometimes of a different colour from the body of the tubes, but that cannot be observed 
without separating the tubes. (The colour of the tubes and pores varies materially with 
the different state of the seeds ; and Mr. Purton has well observed that Boleti are often 
more readily distinguished iu their dried state, than when fresh ; the tubes and pores 
assuming a more decided character. E.)
