Lamprospora 59 



230-300 ju and a diameter of 18-20 /x; spores 1 -seriate, at first 

 smooth and containing one large oil-drop, finally becoming 

 delicately sculptured, reaching a diameter of 12-15 fx, hyaline; 

 spore-sculpturing taking the form of reticulations, the meshes 

 of the reticulations not exceeding 1 ju in diameter, the ridges 

 appearing as delicate lines (when examined with a one-sixth 

 objective) ; paraphyses nearly straight or a little curved, enlarged 

 above, reaching a diameter of 5 ;u at their apices. 



On charcoal beds which have been overrun with mosses. 



Type locality: France. 



Distribution: New York; also in Europe.

(Plate 3, fig. 3.) 



Apothecia gregarious but not crowded, at first globose, ex- 

 panding and becoming subdiscoid, reaching a diameter of 0.5 

 to 1 mm., orange to bright-red; hymenium becoming plane or 

 slightly convex, roughened by the protruding asci, of about the 

 same color as the outside of the apothecium; asci cylindric or 

 subcylindric, gradually tapering below, reaching a length of 

 350 fjL and a diameter of 15-22 ^u; spores 1-seriate, at first smooth 

 and containing one large oil-drop, finally becoming sculptured, 

 reaching a diameter of 18-20 /x. including sculpturing, hyaline; 

 spore-sculpturing taking the form of deep reticulations, the 

 meshes of the reticulations reaching a diameter of 3-5 fx, 3-6- 

 sided, often forming almost perfect hexagonal figures or with 

 the sides of unequal length, 2-3 m deep as indicated by the pro- 

 jecting ridges about the periphery of the spore, the ridges scarcely 

 1 fi thick; paraphyses strongly thickened above. 



On damp soil among mosses and algae. 



Type locality: Yonkers, New York. 



Distribution: New York and Connecticut.

Lamprospora areolata Seaver, var. australis McLennan & 

 Cookson has Identical spore characters but differs mainly in 

 the larger size of the apothecia and in the character of the 

 margin.
