Lamprospora 61 



two rings; spore-rings at first small, increasing in size until they 

 reach a thickness of 3 or 4 n, giving the appearance of four 

 circles where the rings pass about the periphery of the spore, 

 the two rings usually parallel with each other but occasionally 

 shifted out of their normal position and assuming a subspiral 

 position, the whole spore at maturity having a short-cylindric 

 appearance, reaching a diameter of 16-18 /x; paraphyses thickened 

 above and filled with granules, reaching a diameter of 5 fj. at 

 their apices. 



On soil among mosses and algae. 



Type locality: Portland, Connecticut. 



Distribution: New York and Connecticut. 



Illustration: Mycologia 6: pi. 114, f. 9. 



This species, which is very distinct in its spore-markings, has 

 been collected several times by the writer in New York and 

 Connecticut but so far as known has never been found by anyone 

 else.

(Plate 3, fig. 4; 45, fig. 5, 6.) 



Apothecia closely gregarious but not usually crowded, at 

 first subglobose, expanding and becoming short-cylindric or 

 discoid, their bases closely nestling in little cavities in the 

 substratum, reaching a diameter of 1 mm., pale-orange; hy- 

 menium plane or nearly so, roughened by the asci which protrude 

 often half their length above its surface, collapsing after dis- 

 charging their spores and leaving the hymenium pitted, sur- 

 rounded by a fringe-like border; excipulum composed of a 

 palisade of strongly swollen, rather closely septate mycelial 

 threads which extend above the hymenium in irregular clusters 

 giving rise to the fringe-like border, the ends of the peridial 

 mycelium reaching a diameter of 17-18 m, minutely granular 

 within and delicately roughened without; asci cylindric above, 

 tapering below into a short, slender, stem-like base, reaching a 

 length of 200 m and a diameter of 18-20 m, stretching before dis- 

 charging their spores and then reaching a length of 300 jj. and a 

 diameter of 26 m; spores at first smooth, finally becoming sculp- 

 tured, reaching a diameter of 18-20/1, containing one oil-drop 

 which nearly fills the spore, hyaline; spore-sculpturing taking 

 the form of minute blunt spines 1 /x thick and 2 ^ long ; paraphyses 

 septate, gradually enlarged above, reaching a diameter of 7-8 m, 

 minutely granular within and dilutely colored, orange.
