64 The North American Cup-Fungi 



a little brighter than the outside of the apothecium; excipulum 

 composed of a palisade of mycelium, the loose ends of which 

 give rise to a fringe-like border, the ends enlarged, attaining a 

 diameter of 20-25 n at their extremities; asci broad-cylindric to 

 clavate, tapering rather abruptly below into a stem-like base, 

 reaching a length of 300-325 n and a diameter of 30-35 m; spores 

 1-seriate, at first smooth, densely filled with orange granules, 

 becoming sculptured, reaching a diameter of 25 /x excluding 

 sculpturing or 30-32 m including sculpturing, hyaline; spore- 

 sculpturing gradually assuming the form of sharp spines, 2-3 ju 

 in diameter at the base and of about the same length, the spines 

 decidedly conic in form; paraphyses stout, containing several 

 large oil-drops, reaching a diameter of 12 /i at their apices. 



On moist soil among mosses and algae by roadside. 



Type locality: Springside, New Jersey, June 9, 1914. 



Distribution: Known only from the type locality. 



While this and the preceding might be regarded as mere 

 forms of Lamprospora Crechqueraultii, one of the most commonly 

 collected species of the genus, there is such a wide and constant 

 variation in the size and form of the spines with which the spores 

 are decorated that it seems best to segregate the two latter 

 under the names suggested.

(Plate 3, fig. 6.) 



Apothecia gregarious in small clusters, not crowded but 

 rarely with two or three in close contact, at first globose or sub- 

 globose and almost buried in the sandy soil in which they grow, 

 gradually expanding and reaching a diameter of 0.5-1 mm.; 

 superficial but with the base still nestling in the substratum; 

 hymenium plane or nearly so, orange, a little darker than the 

 outside of the apothecium, roughened by the protruding asci 

 which appear as minute white spines; excipulum composed of a 

 palisade of swollen, closely septate mycelium, the loose ends of 

 which give rise to a delicate fringe-like border, the ends of the 

 peridial mycelium about 10 /x in diameter; asci cylindric or sub- 

 cylindric, tapering below into a stem-like base, reaching a length 

 of 275-300 fx and a diameter of 20-30 m; spores 1-seriate, at first 

 smooth and usually containing one large oil-drop, gradually 

 becoming sculptured, reaching a diameter of 18-20 m, hyaline; 

 spore-sculpturing assuming the form of tubercles covering the
