Seaver: Hypocreales of North America 59 



the difference in the size of the spores seems from the descrip- 

 tion to be quite marked, camera lucida drawings of the spores 

 of the two specimens mentioned above which drawings accom- 

 pany this paper show no marked difference either in form or 

 size. I am unable to discover any character by which the two 

 supposed species can be separated notwithstanding the fact that 

 Saccardo (1. c.) has placed the two species in different subgenera. 



12. Nectria Apocyni Peck, Ann. Rep. N. Y. 

 St. Mus. 26: 84. 1874 



Perithecia scattered or crowded in small clusters, subglobose, 

 more or less collapsed when dry, slightly rough, dull red; osti- 

 olum minute; asci clavate, 8-spored, 60—65X12 mic. ; spores 

 2-seriate and often irregularly crowded, oblique, fusiform with 

 ends acute, almost sharp, i-septate, a little constricted at the 

 septum, granular within, 18-22 X 5~6 mic. {pi. 5. /. 12). 



On the lower part of the stems of Indian hemp, Apocynum 

 cannabinum. 



Type locality: North Greenbush, New York. 



Distribution : Known only from type locality. 



Specimens examined: New York, Peck (cotype). 



The species is distinct in the large size and fusiform character 

 of its spores. 



The above description of the microscopic characters are taken 

 from a part of the type collection which was received by the 

 kindness of Mr. Peck. Other characters are recorded from his 

 notes as the specimens are discolored with age and too small to 

 draw conclusions as to the general appearance of the perithecia 

 except that of the size. The species is easily distinguished from 

 any of the other forms listed here by its fusiform spores which 

 approach those of the genus Hypomyces. 



Mr. Peck states (in letter) that he has seen this species but 

 once. He has described the conidia as " subhemispherical or 

 irregular, small, pale red; spores fusiform, straight, .0005-0006 

 in. long." This description would seem to indicate the presence 

 of a stroma although I have been unable to detect one. Until 

 the species has been collected and studied from fresh material, 

 it is difficult to decide this point.
