but regard Holwaya ophiobolus (Ell.) Sacc., H. tiliacea E. & E., 

 Lecanidion leptospermum (Pk.) Sacc, and Chlorosplenium Canadense 

 E. & E. as one and the same species. 



Turning now to the subject of a conidial phase of this species, 

 I find that a plant called Stilbum giganteum Peck was described in 



1871.

The first mention of this plant as a possible imperfect stage of an 

 ascomycete was made by Dr. Peck in his thirty-first report written 

 in 1878, where he said: "I find this associated with Patellaria 

 leptosperma Pk. in such a way as to suggest the probability, at 

 least, that it is a form of the latter species." Ellis and Everhart 



in 



splenium Canadense and Hol\ 



tiliacea in each case call attention to the fact that Coryne Ellisii 

 Berk. {Stilbum magnum Pk.) was found associated with the species, 

 of which it might be a conidial stage. As a matter of fact the 

 association of the two forms has been noted in the great majority 

 of the records of occurrence. The fact that it has not been me 

 tioned in the other cases does not, by any means, go to show that 

 they were not growing together, for such association might have 

 been overlooked. Regarding u Stilbum magnum Pk./' Dr. Peck as- 

 sures me that he never has published such a species, but that the 



# 



occurrence of the name in the literature is probably due to a 

 slip of the mind or pen, Stilbum giganteum being intended in 

 each case. 



Coryne Ellisii Berk, was published in 1873 from material found 

 by Ellis, on basswood logs, at Potsdam, N. Y. No asci were 

 present in the original specimens, but the plant was referred to 

 Coryne probably on account of a superficial resemblance to the 

 members of that genus. Indeed, Berkeley remarked that an 

 examination of fresh material was desirable. The matter was 

 further greatly complicated when Massee, in 1894, redescribed the 

 type of Coryne Ellisii, making it one of the types of a new genus 

 of the Basidiomycetes, called Dacryopsis. Our plant was given 

 the name D. Ellisiana Massee. The basidia were described as 

 " cylindrical, bifurcate, aseptate, springing from the interlaced layer 

 of hyphae at the apex of the stem, either contemporaneous with, 

 or later than, the gonidiophores." 



Such was the state of knowledge regarding this plant when
