tips of two kinds; most tips are racemose with about 12 lat- 
eral branches 3 џ long standing out from an axis 6 y in diam- 
eter, other tips consist of 2 or 3 moniliform bodies — either 
kind of paraphysis may bear a cluster of lateral branches at 
some region more or less distant from the end; basidia 80- 
10012 u; spores hyaline, even, 18-2112-13 y. 
Fructifications 1-2 mm. in diameter, becoming confluent 
into masses 2X1 em. 
On bark of dead Ostrya virginica, Quercus alba, Q. macro- 
carpa, байт, hickory, ete. Canada to Alabama, westward to 
Missouri. 
А. Оакеѕи resembles A. amorphus so closely in aspect that 
it was regarded by Fries in his ‘Hy yeetes Europael' 
as a synonym of the latter species, from which Cooke demon- 
strated that it was clearly distinct by the paraphyses. It may 
be separated at sight by the hymenium of A. Oakesii not be- 
ing convex, by the fructifications becoming very large by con- 
fluence, and by its occurrence on bark of frondose species.
