to the fructifications and at the apex of the fructifications are 
often rough-walled near their tips; hymenium paler, urceolate, 
the margin incurved; basidia simple, with 4 sterigmata; spores 
hyaline, even, cylindric, curved, 6-11 x 1125-45 y. 
Fructifications in dried condition 144-1 mm. high, 200-300 y 
in diameter, where crowded 3-4 to а mm. 
Usually crowded into small areas on pustules or crevices in the 
bark of dead twigs of Alnus, Prunus, Quercus, Betula, Salix, ete., 
or covering broad areas of decorticated wood, fewer and more 
scattered when the wood is very rotten. Throughout Europe, 
Newfoundland to Louisiana, westward to Oregon and British 
Columbia, and in Porto Rico. August to May. Common. | 
European specimens of S. anomala in the exsiccati cited below | 
have somewhat larger spores than those of gatherings from | 
eastern United States but do not differ at all from those of the 
extreme West. Those from British Columbia have spores 7-10 X 
4-414 y and hairs rough near the tips, agreeing in both respects 
. with the Westendorp distribution from Belgium. In one Colo- 
rado and one Montana gathering the spores are 3 y thick, as in 
those of the Berkeley and the Libert distributions, and in another 
Colorado specimen 8-8 y thick as in the Cavara distribution. 
They are 214 » thick in two Montana gatherings and in the 
Rabenhorst distribution, although many of the latter are only 
2 y thick as is the usual thickness of spores of New York and 
New England gatherings. In my opinion these spore differences 
do not warrant specific distinction, and I doubt furthermore 
whether 5. confusa of Europe, separated from S. anomala on the 
sole ground of spores 7-10 X 2-2 y, is really distinct from the 
latter. Тһе distributions by Berkeley, Libert, and Cavara are 
true intermediates.
