238 The North xA.merican Cup-Fungi 



Type species, Bulgaria Ophiobolus Ellis. 



The position of the genus is uncertain. Durand (Bull. 

 Torrey Club 28: 354) places it in the Patellariaceae because the 

 paraphyses cling together above the asci forming an epithecium. 

 This would hardly seem to the writer to be sufficient reason for 

 placing it there since the consistency of the apothecia does not 

 suggest such a relationship.

Conidial structures gregarious, or single, fleshy-gelatinous, 

 consisting of a slender or tapering stem with a length of 3-10 mm. 

 and a diameter of 2 mm. and an ellipsoid, soft, viscid head, 2-6 X 

 2-4 mm.; conidiophores very slender, branched; conidia hyaline, 

 ellipsoid, 1 X 3 m- 



Apothecia cespitose, or single, scattered, stipitate, cup-shaped, 

 becoming expanded and plane, or with the margin reflexed and 

 umbilicate, orbicular, or irregular from mutual pressure, reaching 

 a diameter of 1.5 cm., greenish-black, fleshy-gelatinous, shrinking 

 much in drying; hymenium similar in color to the outside of the 

 apothecium; stem tapering upward, covered with a greenish- 

 brown tomentum which often disappears with age ; asci narrowly 

 clavate, reaching a length of 120-200 /x and a diameter of 10-12 n; 

 spores more or less fasciculate, filiform-cylindric, or very narrowly 

 clavate-cylindric with ends rounded or one end occasionally 

 acute, straight, or curved, hyaline, 14-20-septate, 3-4 X 30-75 ju; 

 paraphyses filiform, slender, longer than the asci, globose at 

 their apices and clinging together. 



On rotten logs of Tilia, Acer, Quercus, and Magnolia, in the 

 crevices of the bark or on the bare wood. 



Type locality: Buffalo, New York. 



Distribution : New York to Ontario, Iowa and West Virginia.
