Lachnella 249 



more than one locule, 243-433 jjl diam., microconidia fusiform, 

 .9-1.2 X 5-5.8 fj. abstricted from the tips of short sporophores, 

 subulate, acute, simple, or verticillately branched. 



Apothecia scattered, or gregarious, sessile, or very short- 

 stipitate, at first subglobose, expanding and becoming shallow 

 cup-shaped, reaching a diameter of 1-2 mm., externally densely 

 clothed with white or whitish hairs; hymenium plane, or slightly 

 concave, bright-orange; hairs cylindric or subcylindric, septate, 

 hyaline, minutely roughened on the outside, reaching a diameter 

 of 4-6 jjL and of variable length up to 200 jjl; asci clavate, reaching 

 a length of 65 jj. and a diameter of 6-7 /z, 8-spored; spores 2- 

 seriate or partially so, fusiform and very sharp-pointed, 2-3 X 

 20-25 fj.; paraphyses lanceolate, or sublanceolate, rather slender, 

 about half the diameter of the ascus. 



On bark of species of Finns, Picea and Larix. 



Type locality: New Jersey. 



Distribution : Maine to Alabama and Texas.

Resembling Lachnella hicolor but differing in the very long, 

 sharply pointed spores. Dasyscypha lachnoderma (Berk.) Rehm, 

 which was thought by Ellis to be identical with this species is 

 quite distinct according to Ayers and Hahn (Mycologia 26: 

 157-180). Some of the above exsiccati were distributed under 

 the latter name.
