Lamprospora 75 



hyaline; spore-sculpturing consisting of four to six tubercles of 

 variable size which extend beyond the periphery of the spore 

 and several indistinct lines or bands extending across the spore 

 and appearing like pieces of coarse twine wound about its surface, 

 the inequality of the tubercles giving to the spore a rather 

 irregular form; paraphyses very slender, reaching a diameter of 

 1-2 M and scarcely enlarged at their apices.

Apothecia gregarious, sessile, at first subglobose, becoming 

 scutellate or shallow cup-shaped, margin often wavy, externally 

 paler than the hymenium, whitish and more or less pruinosey 

 reaching a diameter of 5-10 mm.; hymenium concave or nearly 

 plane, bright-orange; asci cylindric or subcylindric, gradually 

 tapering toward the base, reaching a length of 200-225 ^ and a
