Perithecia superficial, scattered, gregarious or occasionally 

 crowded, globose or subglobose, usually collapsing from the top 

 and becoming pezizoid, at first clothed with a scant covering of 

 delicate, white, mycelial threads (no true hairs) which disappear 

 with age, leaving the perithecia smooth or in very old specimens 

 slightly rough and furfuraceous, 250-500 /i in diameter (mostly 

 about ^oo/jl), varying in color from pale to deep orange, color 

 darker in dried specimens, weathered specimens fading to pale 

 yellow; ostiolum minute, in young specimens just visible and in 

 older forms depressed and inconspicuous ; asci cylindrical or 

 clavate, 8-spored, 50-75/^ x 5-8//; spores broadly elliptical, ob- 

 liquely I -seriate or becoming crowded and partially 2-seriate, 

 thick-walled, i -septate, not constricted, with i large, conspicuous 

 oil-drop in each cell, 10-14// X .4-6 /^ (mostly 10 x 5/«); para- 

 physes short, branched, not conspicuous. [Plate 15.] 



On decaying decorticated wood, more rarely on bark, fungi, 



and old hemp cloth. 



Type locality : Mecklenburg, Germany. 



Distribution : New York to Ontario, North Dakota, Cali-

*Tbe type of this species in the Ellis collection is so scant that scarcely a perithe- 

 cium in good condition could be found, and it is impossible to make a thorough study 

 of gross characters. The spores are typical of the above species.
