BURT—MERULIUS IN NORTH AMERICA 313 
fresh), with a few radiating, branching folds and less prom- 
inent connecting folds, forming radially elongated pores 
about 4 to a mm. transversely; structure and spores not 
known. 
One fructification of the type is 5х4 mm., and the other 
3 mm. in diameter; both are thick in proportion to size. 
On wood. Texas. C. Wright, 3144, type (in Kew Herb.). 
In his comment on M. Wrightii in connection with the orig- 
inal description, Berkeley states that this species is appar- 
ently intermediate between Laschia and Merulius. I could 
find no specimens of C. Wrightii in Curtis Herbarium and 
am indebted to Miss E. M. Wakefield for notes on the type 
which have made possible the above description, and also for 
two sketches which illustrate the species. Miss Wakefield 
adds that it is not possible to say from the specimens whether 
they were attached to wood.
