Explanation of Plate V. 



The spores on this plate were drawn with the camera lucida, the object 

 being to show the comparative size and form of the spores in the different 

 species of the genus Nectria. The drawings are from type material where 

 such is available. In a few cases the type specimens were too scant to permit 

 of such drawings. 



1. Nectria Peziza (Tode) Fries. Drawn from material collected by the writer. 



2. Nectria diplocarpa Ellis & Everh. Drawn from type material. 



3. Nectria tremelloides Ellis & Everh. Drawn from type material. 



4. Nectria flavociliata Seaver. Drawn from type material. 

 Nectria bicolor Ellis & Everhart. Drawn from type material. 



5. Nectria lactea Ellis & Morgan. Drawn from type material. 



6. Nectria Rexiana Ellis. Drawn from type material. 



7. Nectria squamulosa Ellis. Drawn from type material. 



8. Nectria rubefaciens Ellis & Everh. Drawn from type material. 



9. Nectria thujana Rehm. Drawn from Ellis, N. Am. Fungi 160. This 



material was collected in the type locality and identified by Mr. Ellis, 

 who collected the type material. Cotype material has been examined, 

 but the perithecia are so scarce that it was impossible to find any in 

 good condition. 



10. Nectria Eucalypti Cooke & Harkness. Drawn from material collected by 



Harkness in the type locality. Probably cotype. 



11. Nectria depallens Cooke & Harkness. Drawn from material collected by 



Harkness. Probably cotype. 



12. Nectria Apocyni Peck. Drawn from cotype material. 



13. Nectria sulphur ea Ellis & Calkins. Drawn from type material. 



14. Nectria truncata Ellis. Drawn from type material, in which it was diffi- 



cult to find mature spores. 



15. Nectria conigena Ellis & Everh. Drawn from type material. 



16. Nectria filicina Cooke & Harkness. Drawn from material collected by 



Harkness. Probably cotype. 



17. Nectria sanguinea (Bolton) Fries. Drawn from Rehm's Ascomyceten 1771. 



18. Nectria episphaeria (Tode) Fries. Drawn from material collected in 



Ohio on Diatrype sp. 



19. Nectria Papilionacearum Seaver. Drawn from type material. 



20. Nectria Brassicae Ellis & Sacc. Drawn from N. Am. Fungi 572. Prob- 



ably cotype.
