Lamprospora Crec'hquerauUii var. macrantha Boud. Hist. Class. Discom. Eu. 



69. 1907. 



Apothecia gregarious but not usually crowded, subglobose, 

 becoming short-cylindric, finally discoid, externally pale-yellow, 

 reaching a diameter of 1-2 mm. ; hymenium becoming plane or 

 very slightly concave, with a delicate fringe-like border, pale- 

 orange; excipulum giving rise to a palisade of mycelium above, 

 which forms the fringe about the hymenium, the ends of the 

 palisade mycelium clavate, reaching a diameter of 25-30 n; asci 

 cylindric above, gradually tapering below into a stem-like base, 

 reaching a length of 300-325 /x and a diameter of 30-35 /x; spores 

 1-seriate from the first, smooth and densely filled with oil-drops, 

 becoming sculptured apparently by the accumulation of proto- 

 plasmic material about the outside of the spore, reaching a 

 diameter of 20 ju excluding spines and 30-35 fj. including spines, 

 hyaline; spore-sculpturing at first indistinct, gradually assuming 

 the form of sharp spines which give the spore a beautiful 

 crystalline appearance, the spines reaching a length of 10 ju and 

 a diameter of 3-4 /x at the base; paraphyses strongly enlarged 

 above, reaching a diameter of 7-10 fx at their apices. 



On clayey soil in wet places. 



Type locality: France. 



Distribution: New York; also in Europe.

10. Lamprospora brevispinosa Seaver, sp. nov. 



Apothecia gregarious, at first globose and closely nestling in 

 little depressions in the substratum, expanding and becoming 

 discoid or subdiscoid, externally orange, reaching a diameter of 

 1 mm.; hymenium delicately roughened by the protruding asci,
