30—PLUTEUS UMBONATUS. 
Pileus campanulate, with a prominent blunt umbo, red¬ 
dish umber, excepting the umbo which is pale almost white, 
smooth, strongly striate to the umbo. Umbo even, smooth. 
Flesh very thin excepting the thickened umbo. Gills broad, 
free, flesh colored. Stipe white, solid, smooth, slightly taper¬ 
ing upward. Spores globose, 5 me. with granular contents 
when fresh. 
This description has been drawn from a single specimen found growing in 
the leaf mold. It does not seem to approximate any species we can find described. 
It is probable the plant was not fully developed and that the cuticle of pileus 
would split when expanded into long striations similar to longistriatus, to which 
it appears close, save in its prominent thickened umbo. 
31—PLUTEUS TOMENTOSULUS. 
Pileus expanded, dry, even, white with a pinkish cast, 
minutely squamulose-tomentose. Gills free, flesh colored. 
Stem solid, equal, white, densely fibrillose. Spores subglo- 
bose, 5-6 me. nucleate. 
We have found but a single specimen growing in the soil in woods. Prof. 
Peck described it from “decaying wood.” Our plant agreed with description save 
it was not subumbonate and we would describe the stem as densely fibrillose 
rather than pubescent. 
32—PLUTEUS NANUS. 
Pileus expanded, brown with a dark sooty center when 
dry, rugulose when wet, even when dry, minutely densely 
• scurfy, slightly striatulate on the margin when wet, not when 
dry. Gills free, rose-color. Stipe white, slightly grayish at 
base, equal, solid, smooth. Spores globose, 5 me.. 
We found it but once growing in wet soil by side of a ravine. Owing to its 
habitat (it is usually recorded on decaying wood,) and to the dissimilarity be¬ 
tween our photograph in size and Cooke’s figures there may be some question of 
our determination. Still we feel our plant answers the published descriptions of 
the species, even as to its small size. 
The “shiny” appearance of our photograph is not natural, but due to the 
specimens photographed, having lain in water and become water soaked. 
33—PLUTEUS TORTUS. 
This specimen w T e have only seen once. It was collected several years ago, 
and the notes made at the time were scanty. As we referred it to “nanus” when 
collected we presume the pileus was pruinose. Our notes simply state “The 
brownish pileus has a darker umbo and it is conspicuously and prominently rugu¬ 
lose. Stem very smooth, shining, white, solid, twisted .” Our photograph does 
not show the rugulose pileus and we presume it dried and became even before it 
was photographed, but it does show in a characteristic manner, the peculiar 
twisted stipes. Whether this is an accidental feature of these specimens or 
peculiar to the species is only conjecture. If the latter, the name we propose 
(pro tern.) tortus, will not be inappropriate.
