menium unilateral. This, however, is not the case in our sections 

 of his plant. 



The present species is not to be confused with C. dendroidea. 

 Fries's colored figures of the latter (Icon. Hymen., p. 200, fig. 1) 

 strongly recall our plant in structure and color, the yellowish tips 

 abruptly contrasting, but that is very distinct and belongs to a 

 different group. The spores from authentic specimens determined 

 by Robert Fries are smooth, elliptic, 4-4.8 x 8-10[/. (pi. 91, fig. 21).

LACHNOCLADIUM 



If the usage of modern mycologists is to be accepted, the genus 

 Lachnocladium is in a state of chaos. It would have been much 

 better if Persoon's original genus Mcrisma had been retained and 

 modified as occasion demanded by the addition of new genera, as 

 was done in fact by Leveille in the establishment of his genus 

 Lachnocladium (Ann. Sci. Nat., 3rd. ser., 5: 158, 1846, as Erio- 

 cladus, later changed to Lachnocladium) . In redefining the genus 

 Merisma (1. c, p. 157) Leveille made little change in Persoon's
