absence of cystidia. The pileus is commonly obtusely umbonate, but in the form 
figured by Bresadola the umbo is acute; in other respects, however, his plant is 
typical. 
There are, however, apparent contradictions to the above view. Fries (Hym. 
Eur., 232) gives a good description of Schaeffers Fungus as defined above, and 
quotes Schaeffer’s figure, but at the end of his remarks on the species adds ‘ sporae 
scabrae.’ 
Fries did not personally investigate the microscopic characters of spores, hence 
this statement must have been obtained from some outside source, and its value 
questionable. 
In Cooke’s Xllust., pi. 383, the spores are shown to be rough ; this is a mistake, 
however, as the specimens from which Cooke’s figure was drawn, now in Herb. Kew., 
have smooth spores ! 
In Saccardo’s Sylloge, v, p. 779, the Friesian description of I. fastigiata is copied, 
with an added description of rough spores and cystidia, obtained from some other 
source, hence valueless. 
In British Fungus-Flora, ii, p. 192, not having an authentic specimen, I copied 
Saccardo’s account of spores and cystidia, hence this cannot be urged as an argument. 
(Berkeley's type of I. Curreyi examined.) 
Spores smooth , no knowledge of cystidia. 
* Pileus dark coloured. 
mutata, Mass., Ag. ( Hehl ) mutatus, Peck, 24 Rep. State Mus., p. 69 ; Sacc., 
Syll. v, p. 799. 
P. convex or broadly conical, gibbous, rough with squarrose, fasciculate, floccose 
scales, which at length disappear except at the disc, dark brown, 1-3-2 -5 cm.; 
g. broad, crowded, ventricose and very deeply emarginate, dark rusty-brown, edge 
whitish ; s. slender, equal, solid, floccosely scaly, often 'curved at the base, colour of 
p., 5-7-5 cm.; sp. elliptical, smooth, 10 jx. 
Damp ground in woods. United States (Catskill Mts.). 
The changed appearance produced by the disappearance of the scales suggests 
the specific name (Peck).
