BADHAMIA 37 



said to differ from B. panicea in the color of the Plasmodium, and the 

 larger, darker, more irregular spores, and from B. foliicola in the spore 

 characters and the whitish gray sporangia. 



17. Badhamia foliicola List. 



Jour. Bot. 35 : 209. 1897. 



Sporangia 0.5-0.6 mm. in diameter, subglobose or ellipsoidal, irides- 

 cent-gray, stipitate or sessile; peridium thin, rugulose, sparingly cal- 

 careous, when empty white; stipe when present short, yellowish, 

 flaccid; capillitium badhamioid; spores free, delicately spinulescent, 

 dusky violaceous, 11-12 n. Plasmodium orange. 



If Badhamia microcarpa Schroet, Krypt. Fl. Schles. 3 (1) : 131, 

 1886, should prove to be the same, as is suggested by Lister and Schinz, 

 that name would take precedence. Mr. Hagelstein reports the species 

 as common on Long Island. The color of the Plasmodium, quoted 

 from Miss Lister, is of importance only when constant and confirmed 

 by other criteria. 



Meylan, Bull. Soc. Vaud. Sc. Nat. 57 : 301, 1931, reports a yellowish 

 phase from Switzerland which he calls form flavescens.

18. Badhamia alpina G. List. 



Jour. Bot. 52 : 99. 1914. 



Sporangia scattered or clustered, sessile, subglobose or hemispherical 

 on a broad base, 0.5 to 0.9 mm. in diameter, gray or iridescent, usually 

 seated on a dark hypothallus; capillitium a close network of slender 

 tubes enclosing scanty deposits of lime; spores free, grayish lilac, 

 almost smooth or very minutely warted, 10-12 fj.. Plasmodium pale 

 yellow or yellowish white. 



This description is from Lister. Close to B. foliicola, differing in 

 pale color of plasmodium, more hemispherical sporangia and paler, 

 smoother spores. 



Known from the Alps and Sweden. Not yet reported from North 

 America.
