deeply into polygonal areas, showing tho white flesh underneath. They 
agree exactly with “Type No. 1” of the species collected by Under¬ 
wood, and it may he that the description should be enlarged to include 
the forms listed above under B. edulis. Plants growing in dry sod 
where there was little shade would naturally become deeply cracked. 
Under beech, south edge of grove, Blahnik’s, August, Algoma. 
Boletus glabeilus Pk. [Geriomyces miniato-olivaceus (Frost) M.] 
Under pine, along pasture borders, Fluno’s bluff, June, Mauston. 
Boletus luridus Schaeff. {Suillellus luridus (Schaeff.) M.] The 
stipe is* merely dotted with fine points and not reticulated, dark-red or 
yellow. The tubes are minute with uneven cinnabar-red mouths. The 
quick change of color of the flesh to dark blue when broken is very 
characteristic. Under beech and maple, Blahnik’s grove, August, Al¬ 
goma. 
Boletus n ire us Fr. A variety of the rough-stiped form which is 
white throughout. It is much smaller than B. scaber and has only a 
rough stipe in common with that species 1 and B. punctipes. This white 
form seems to be a distinct species with constant characters. Under 
alder and tamarack, Detjen’s swamp, September, Algoma. 
Boletus piperatus Bull. •[Geriomyces ferruginatus (Batsch.) M.] 
Where snails had eaten the tubes, the flesh was rose-pink. The tubes 
at the margin are 5-6 mm. long, giving the plants a blocky appearance. 
Murrill, Mycologia, PI. 19, fig. 2, gives an excellent figure of this spe¬ 
cies. Common on mossy hummocks, Blahnik’s grove, August, Algoma. 
Boletus Russellii Frost [Ceriomyces Russellii (Frost) M.] North 
side of Mile Bluff, August, Mauston. 
Boletus scaber Bull. •[Ceriomyces viscidus (L.) M.] Common in 
mixed woods, Ihlenfeld’s, July to September, Algoma.- 
Boletus spectabilis Pk. The pileus is covered with a reddish fur¬ 
like tomentum which cracks into patches forming triangular scales 
which are easily rubbed off. In wet weather these patches are jelly- 
like. The lavender colored veil, which covers the tubes at first, melts 
into a jelly as the plant ages. The purple-brown spores are charac¬ 
teristic of the species. The Bohemians will not eat this Boletus. In 
sw r amps along the Ahnapee river, September, Algoma. 
Boletus subluteus Pk. In sandy soil under pine and oak, Fluno’s 
Bluff, August, Mauston. 
Boletus subtomentosus L. *[.Geriomyces subtomentosus (L.) M.] 
Common around Mile Bluff, July, Mauston. 
Boletus sphaerosporus Pk. This species was found growing 
abundantly in grassy places along the drive in the University grounds 
during the first weeks in June. The appearance of young specimens 
is uninviting owing to the purplish slime which covers the thick leath¬ 
ery veil extending from the stipe to the margin of the pileus. The
