Seaver: The Genus Lasiosphaeria

septate?), occasionally with one end of the spore enlarged form- 

 ing a conspicuous head, 60-70 X 3-4/^ ipl- 2, f. 8-p). 



Type collected on rotten wood of Hicoria at Tuskegee, Ala- 

 bama, July 29, 1897, G. W. Carver j/j (herb. N. Y. Bot. Garden). 



Distribution : Alabama and Carolina. 



ExsiccATi: Rav. Fungi Car. Exsicc. 5: 66 (as Sphaeria 

 Rhacodium). 



The material from which the above species is described was 

 labeled sp. nov." in the herbarium of the New York Botanical 

 Garden, and while closely related to Lasiosphaeria hispida seems 

 to differ in the more slender spores which are multiguttulate and 

 finally (many-septate ?) with the upper end occasionally enlarged 

 into a conspicuous head. 



In looking over the specimens under the name of Lasiosphaeria 

 hispida several were found which agree with the one described 

 here. Whether the enlargement of the end of the spore is a 

 variable character as has already been noted in Lasiosphaeria 

 mucida, I am unable to determine, but it is possible that this may 

 be found to be the case.

 only slightly prominent, slightly hairy becoming naked with age 

 and minutely rough, very hard and carbonaceous ; asci cylindric, 

 8-spored ; spores cyhndric, slightly curved, 20-27 X 4 hyaline
