104. Endogone lanata, sp. nov. 



Subglobose, 0.7 cm. in diam., color white; glei^a flocculent, white; con- 

 cepticles numerous, wooly; asci brown, globose, 100 11 in diam. 



Type, No. 45, Harkness Coll. 



In forests in the Sierra Nevada mountains, Placer County,

Minute, 0.3 cm. in diam., convex surface inferiorly concave, fibers of 

 mycelium extending from the concave surface; gleba white, flocculent; asci 

 48-70 !J. in diam., spherical, attached to an elongated pedicel (6 x 180 /z); spore- 

 like bodies numerous, globose, homogeneous, white, 7 ij. in diam. 



Type, No. 103, Harkness Coll. 



Upon the surface of the ground in dense shade of Sequoia

Parasitic, perithecia papillose discoid, minute, membranaceous; ostiolum 

 hidden; spores heterogeneous, fifty or more in each of the perithecia, ellipti- 

 cal, black when mature, non-guttulate, 12 x 14 /jt.

Parasitic within the parenchyma of PseudohydnoU'ia 

 carnea. 



There is a marked dissimilarity between this species and 

 that of S. Zobelii Tul., not only in the general outline of 

 the perithecia and its ostiolum but in the size of the spore.
