An examination of the figures of the European plant shows that the veil
often slips off from the lower portion of the stem in _B. luteus_,
especially in the figures given by Krombholtz, T. 33. In some of these
figures the veil forms a broad, free collar, and the stem is then dotted
both above and below, as is well shown in the figures. In other figures
where the lower part of the veil remains as a sheath over the lower part
of the stem, the dots are hidden. I have three specimens of the _B.
luteus_ of Europe from Dr. Bresadola, collected at Trento,
Austria-Hungary: one of them has the veil sheathing the lower part of
the stem, and the stem only shows the dots above the annulus; a second
specimen has the annulus in the form of a collapsed ring near the upper
end of the stem, and the stem dotted both above and below the annulus;
in the third specimen the annulus is in the form of a broad, free
collar, and the stem dotted both above and below. The plants shown in
Fig. 174 (No. 4124, C. U. herbarium) were collected at Blowing Rock, N.
C., during September, 1899. They were found in open woods under Kalmia
where the sun had an opportunity to dry out the annulus before it became
collapsed or agglutinated against the stem, and the broad, free collar
was formed. My notes on these specimens read as follows: "The =pileus=
is convex, then expanded, rather thick at the center, the margin thin,
sometimes sterile, incurved. In color it runs from ecru drab to
hair-brown with streaks of the latter, and it is very viscid when moist.
When dried the surface of the pileus is shining. The =tubes= are plane
or concave, adnate, tawny-olive to walnut-brown. The tubes are small,
angular, somewhat as in _B. granulatus_, but smaller, and they are
granulated with reddish or brownish dots. The =spores= are walnut brown,
oblong to elliptical, 8--10 × 2--3 µ. The =stem= is cylindrical, even,
olive yellow above, and black dotted both above and below the annulus."
