American plants. The perithecia develop quite readily in the 
laboratory. 
After a study of cotype material of Hypomyces hyalinus 
(Schw.) Till, in the herbarium at Paris, Maire agrees with the 
writer in regard to the spore characters, the species being char- 
acterized by the unequally septate, verrucose spores. Hypomyces 
inaequalis Peck is used as a synonym as has been previously done 
by the writer (1. c.). Maire calls attention to the fact that the 
species has also been recorded from Europe, a fact which was 
overlooked in our own monograph.® 
Hypomyces macrosporiis Seaver is made a synonym of Hypo- 
myces armeniacus Tul. When this species was described a note 
was appended stating that the plant was first thought to be Hypo- 
myces ochraceus (Pers.) Tul. The absence of material illustrat- 
ing this species in Persoon’s herbarium, together with several 
apparent differences, led me to describe the species as new. Maire 
points out that it is identical with Hypomyces armeniacus Tul. in 
the Paris herbarium and adds Hypomyces ochraceus (Pers.) Tul. 
as a doubtful synonym. These observations are important as 
they clear up the identity of our North American species. The 
species is characterized by the very large verrucose spores. 
Specimens of Hypomyces tegillmn Berk. & Curt, in the her- 
barium at Kew show perithecia, but no mature asci were seen. 
iMaire reports that cotype material in the Paris herbarium have 
asci in good condition, and completes the description of the spe- 
cies. Hypomyces papyraceus (Ellis & Holw.) Seaver differs in 
the much smaller spores. 
Nectriopsis -is proposed as a new genus, differing from Bysso- 
nectria in its 2 -celled spores. Hypomyces violaceus Tul., which 
was placed in the genus Byssonectria by the writer, is included 
in the new genus. Hypomyces aureo-nitens Tul. is also included 
in the new genus. The American material described under this 
name in North American Elora is said to differ in its much 
smaller spores and the absence of the Penicillium-type. of conidia. 
The paper is illustrated with one plate containing careful draw- 
ings of the spores of the species discussed, and is a valuable addi- 
tion to our knowledge of the North American Hypocreales.
