54 The North American Cup-Fungi 



just as striking as B. areoJata. The spores are described as globose, 20 n in 

 diameter, rufous and areolate. No specimen has been seen, but the description 

 is suggestive of Ascodesmis.

Apothecia small to medium-sized, shallow cup-shaped or 

 more often scutellate or discoid, externally smooth or verrucosa 

 but never clothed with well-developed hairs; hymenium concave, 

 plane or convex, usually bright-colored, some shade of red 

 orange or yellow, more rarely pallid or dark-colored, purple or 

 brownish-black, often roughened by the protruding asci; asci 

 usually clavate or subcylindric, 8-spored; spores globose or sub- 

 globose, at first smooth, becoming sculptured or remaining 

 permanently smooth, hyaline-or faintly colored; spore-sculpturing 

 very variable, consisting of spines, minute warts, coarse tubercles 

 or ridges, the ridges often assuming the form of reticulations, or 

 in one case forming rings about the spore ; paraphyses filiform or 

 clavate, straight or curved. 



Type species, Ascobolus miniatiis Crouan. 



Apothecia small, not exceeding 5 mm. in diameter 

 (usually 1 or 2 mm.) ; spores hyaline or sub- 

 hyaline. 

 Spores sculptured (reticulate, spinulose, verrucose, 

 tuberculate, or annulate). 

 Spore-sculpturing consisting of ridges. 



Ridges giving rise to reticulations (net-like 

 markings over the surface). 

 Reticulations shallow, barely roughening 

 the surface of the spore. 

 Spores at maturity 15-22 yu in di- 

 ameter, ridges of reticulations 

 about 1 ^t thick. 

 Apothecia reaching a diameter of 



3-5 mm.; reticulations regular. 1. L. Crouani. 

 Apothecia not exceeding 1-2 mm. 

 in diameter; reticulations very 

 irregular. 2. L. laetiruhra.
