Later, Rex says this seems really to be a form of bale contorta. Lis- 
ter includes it in the above species. 
63. 7. abrupta Cooke, Grev. 5: 150. Cooke B. Myx. 256 
(Portland). Lister refers this form to 7. perszmilzs Karst. 
64. T. subfusca Rex. Jackman (Harvey), Sept.,1895. Lister 
makes this var. swbfusca, under 7: Botrytis. Morgan says, “ The 
stipe is much shorter than the type I have from Dr. Rex, and the 
elaters are remarkably branched.” 
65. TZ: affinis De Bary. Greenfield (Harvey), Sept., 1895. 
66. 7. nana Mass. Westbrook (?). According to Lister this is 
the same as Hemiarcyria Wigandii Rost., a form which we record 
under that genus from Orono. 
67. Oligonema nitens Rost. Orono, Sept., 1889. Greenfield, 
1893 (Harvey). Our specimens are finely developed. 
68. Hemiarcyria (Hemitrichia) rubiformis (Pers.) Rost. Cum- 
berland (Blake). Rangely (Rex). Orono (Harvey). 
69. H. clavata (Pers.) Rost. Common on fallen trunks. Sept. 
to Nov. Rangely (Rev). Orono, Greenfield (Harvey). 
70. H. serpula (Scop.) Rost. Bar Harbor (Rex). 
71. H. Wigandi Rost. Orono, Oct., 1892 (Harvey). Rex 
says, “ This has not been recorded from America before. It an- 
swers the description well, except that the spore and thread 
measurements are less.” Lister refers Zrichia nana Mass. which 
_ is reported from Westbrook, Me., to this species. : 
72. H. leiocarpa Rost. On vegetable debris. Portland 
(Bolles). Grev. 5: 150. 
73. H. stipata Schw. Orono, Oct. ’90, Oldtown, Sept. ’95 
(Harvey). Rex says of the specimens collected in 1890, “ That 
I have specimens in abundance of this species from several locali- 
ties in this country, but yours has the most strongly marked capil- 
litium. It is valuable for that reason.” Lister refers this to Avcy7i@ 
stipata Lister. 
74. H. plumosa Morgan. On fallen trunks. Sept. 1895, Old- 
town (Harvey). Lister makes no mention of this.
