32 THE MYXOMYCETES 



8. Badhamia ovispora Racib. 



Rozpr. Mat.-Przyr. Akad. Krak. 12 : 72. 1884. 

 PI. II, Fig. 33. 



Sporangia minute, 0.5 mm. in diameter or less, sessile, depressed-glo- 

 bose or plasmodiocarpous, white or ochraceous, sometimes on a dark 

 red hypothallus; sporangium wall thick, calcareous, often scaly; capilli- 

 tium white, often denser at the center to form a pseudocolumella; spores 

 free, pale purple-brown, elongate, ellipsoidal or irregular, 10-15 X 8-10 //. 



On old straw, dead wood, rabbit dung, etc. Not common. Pennsyl- 

 vania, Massachusetts; Europe. 



9. Badhamia decdpiens (Curtis) Berk. 



Grev. 2 : 66. 1873. 



PI. II, Figs. 27, 28. 

 1848. Physarum decipiens Curtis, Am. Jour. Sc. II. 6 : 352. 

 1873. Physarum chrysotrichum Berk. & Curtis, Grev. 2 : 66. 

 1876. Badhamia chrysotricha (Berk. & Curtis) Rost., Mon. App. 4. 



Sporangia gregarious, depressed-spherical or ovate, sessile, occa- 

 sionally plasmodiocarpous, dull yellow, roughened by the rather nu- 

 merous calcareous scales; columella none; capillitium dull orange, 

 strongly calcareous, only slightly widened at the nodes, sometimes 

 somewhat physaroid; spore-mass black; spores free, pale violet, very 

 minutely spinulose, 10-12 jx. Plasmodium yellow. 



Among free-spored badhamias this and the next species are at once 

 distinguished by the color and the globose spores. If the original de- 

 scription can be regarded as denning anything, this is the same as 

 Physarum chrysotrichum B. & C. It resembles somewhat Physarum 

 serpula Morg., but differs externally in color and in the surface scales, 

 which are not perceptible in the Physarum. The present species also 

 resembles Cienkowskia reticulata (A. & S.) Rost., but has a different 

 capillitium. See under that species. 



According to Brandza (1929), when development occurs under moist 

 conditions the colors are paler and the capillitium distinctly bad- 

 hamioid, while under dry conditions the color becomes orange-yellow 

 and the capillitium more or less physaroid. 



Chiefly eastern and American. New England, Pennsylvania, Ohio, 

 South Carolina, Bolivia; reported also from western Europe and 

 Rumania. 



10. Badhamia viejdescens Meylan 



Bull. Soc. Vaud. Sc. Nat. 53 : 452. 1921. 

 Sporangia scattered or loosely clustered, stalked, subglobose, 

 0.5-0.8 mm. in diameter, yellow-green or gray with a yellow or red-
