178 Rhodora [ AUGUST 
The three common species of the section Versipelles are common 
also at Alstead, the most frequent being, of course, B. scaber Fr., which, 
much to the annoyance of driving parties, has always to be investigated 
along roadsides, lest something more interesting may be overlooked. 
There are always exciting possibilities about a glimpsed Boletus. B. 
` versipellis Fr. is less frequent, but common enough to earn the neglect 
of collectors. B. chromapes Frost, on the other hand, partly from the 
attractive contrast of the pink of the pileus and the yellow of the stem, 
and partly because it occurs less frequently than expected, has usually 
been brought in when found. It begins to appear late in July. 
Two species of Hyporhodii have been collected, B. gracilis Peck, 
which is not common, and B. /z//eus Bull. which is. There is little to 
be said of either. B. fed/eus, however, is not so large as I am accus- 
tomed to see it. A small form of it is not infrequent on stumps, pre- 
sumably of hemlock, as noted by Peck. 
B. cyanescens Bull. and B. castaneus Bull. represent the Cariosi, 
neither of them frequent so far as seen. 
Since the preceding account was in type, a few more forms deserv- 
ing notice have been collected. One of these is plainly referable to 
B. badius Fr., although the viscid cap is hardly shining when dry, 
and the flesh shows no blue, but after a time a pinkish tint. The stem 
is somewhat lined and finely brown-punctate. It agrees almost exactly 
with the figure in Michael's Führer für Pilzfreunde, a little book whose 
excellent colored plates ought to be better known. B. afinis Peck 
is sometimes confounded with B. badius, but is a much softer species, 
with flesh that usually turns yellowish, and pores that show bright ochra- 
ceous tints, whereas those of B. badius turn promptly to green when 
wounded. 
A single specimen, which can be only B. griseus Frost, was found 
July 28, 1900, on a drive to Keene. The grayish cap, small white 
tubes, and beautifully reticulated whitish stem identify it, in spite of 
some discrepancy in its proportions. 
Another single specimen, obtained on the same drive, is a form, akin 
to B. luridus which shows distinctly the characters ascribed to BZ, 
erythropus Pers. It has a long slender cylindrical stem, the flesh of 
which is red all through within. Its spores are large, 17 by 61% p. 
Among many forms, which were at first placed with B. /uridus one, 
which was sent to Mr. Peck, has been referred by him to B. vermicu- 
losus Peck. The velvety pileus is brown, or yellowish brown; paler
