Lamprospora 



55 



spores at maturity 12-15 yu in di- 

 ameter, reticulations very delicate, 

 scarcely more than lines over the 

 surface of the spore. 

 Reticulations deep, extending 2 ^ or 

 more beyond the periphery of the 

 spore and appearing as a broad band 

 about its surface. 

 Ridges not giving rise to reticulations. 



Ridges usually curved and extending in 

 \arious directions as in some species 

 of Ascoboliis. 

 Ridges giving rise to two distinct rings 

 about the spore. 

 Spore-sculpturing consisting of spines, warts, 

 or tubercles. 

 Spores covered with spines. 



Apothecia not exceeding 1 mm. in di- 

 ameter; spines short, blunt. 

 Apothecia at maturity 1-5 mm. in di- 

 ameter; spines long and very 

 sharp. 

 Spores (including spines) 20-25 lu in 



diameter; spinas slender. 

 Spores (including spines) 30 ij. or 

 more in diameter; spines stout. 

 Spines reaching an extreme length 

 of 10 fx, with a diameter of 3 to 

 4 M at the base. 

 Spines conic, about 2-3 ^ in 

 diameter and rarely exceeding 

 the same in length. 

 Spore-sculpturing consisting of warts or tu- 

 bercles. 

 Tubercles large, twelve or rarely fourteen 

 or fifteen about the circumference of 

 the spore. 

 Individual tubercles smooth, not sculp- 

 tured. 

 Individual tubercles covered with mi- 

 nute sculpturing, giving them a trans- 

 lucent appearance. 

 Tubercles small, about twenty or more in 

 the circumference of the spore. 

 Spores subglobose, on bark among 



moss. 

 Spores perfectly globose, on soil. 

 Apothecia pale-orange. 

 Apothecia violaceous.
