NEW OR NOTEWORTHY GEOGLOSSACEAE 



ELIAS J. DURAND 



Since the publication of the writer's monograph of the Geo- 

 glossaceae of North America, in 1908, numerous' specimens have 

 been collected, or have been received from correspondents in 

 various parts of the country, which have thrown additional light 

 on certain little known forms. Authentic specimens of several 

 species previously known only by description have also become 

 available, which have, in one or two instances, materially modified 

 the views expressed in the monograph, or have cleared up cer- 

 tain points at that time doubtful. The most valuable collection 

 examined is one of 45 numbers, made by Mr. W. H. Long, in 

 Maryland and Virginia, in 1910. 



Geoglossum intermedium Durand 



Virginia: Great Falls and Cherrydale, Sept., 1910, W. H. Long 

 nos. 2236, 2251 and 2269 (D). 



The three collections by Mr. Long agree well with the two pre- 

 vious ones from New York and Ontario, and abundantly prove 

 the validity of the species. 



Geoglossum pumilum Winter, Grev. 15:91. 1886 



Ascomata very small, 0.5-2 cm. high, slender, black ; ascigerous

 very slender, brownish black, squamulose, especially above, 0.5 

 mm. thick when dry. Asci clavate, stout, 185-200 X 20-25 /x. 

 Spores 8, fascicled in the ascus, clavate-cylindric, tapering each 

 way from above the middle, 15-septate, 104-125 X6/t (majority 

 110-115/x), deeply colored. Paraphyses longer than the asci,
