DESCRIPTION OF PLATE. 
Fig. 1. Spores showing variation in shape and size. 
2. Spores germinating in artificial cultures. 
3. Farther development. 
4. 5, 6, 7. Spores germinating and some of the hyphae producing the dark-brown 
cells. 
8. Spores germinating in pure water, producing immediately the special cells. 
9. Spores germinating in weak nutrient medium producing special cells and 
a few spores. 
10. Same. 
11. Growth from one spore in rich nutrient medium 65 hours from time of sow¬ 
ing, showing crown clusters of spores around ends of fertile hyplue ; one 
of the special cells by budding has produced an imperfect sclerotium. 
12. Ends of hyphae in an old culture showing special cells and one seta. 
13. Section through acervuli on boll. 
14. Same, more highly magnified. 
15. Section from stem showing special cells and imperfect sclerotia and origin 
of setae. 
16. Peculiar enlarged cells from a cluster. 
17. Setae from old specimens on dried part of boll. 
18. Setae from leaf. 
19. Young setae from cotyledon of one of the plants inoculated with spores from 
a boll. 
Figs. 2-12. From artificial cultures, 13 to 18 from natural specimens, 19 from inocula¬ 
tion. 
All excepting 13 drawn to the same scale with aid of camera lucida. Fig. 13 drawn 
with aid of camera lucida to smaller scale. 
MYCOLOGICAL NOTES II. 
Plate vii. 
By George Massee. 
SARCOMYCES, Mass., (nov. gen.) 
Receptacle subgelatinous, subsessile, erumpent, attached by a nar¬ 
row base; hymeniuin convex, even, margin acute; asci cylindrical; 
spores uniseriate, colored, muriforinly septate; parapbyses numerous. 
Allied to HcematOmyxa , Sacc., but distinguished by the even inargin- 
ate hymenium and the uniseriate spores. It is doubtful whether the 
last-named genus really belongs to the Bulgariece . 
Sarcomyces vinosa, Mass. (Figs. 1-3.) Erumpent; substipitate, 
expanding into a more or less circular fleshy disk, plane or convex below, 
margin acute, patent when moist, incurved when dry; hymenium con¬ 
vex, even, every part perfectly glabrous and dark purple-brown ; asci 
cylindrical, attenuated and usually curved at the base; spores uniseri¬ 
ate, four in an aseus, elliptical, ends subacute, usually rather oblique, 
at first triseptate then with septa formed parallel to the long axis of 
the spore, slightly or not at all constricted at the septa, clear brown,
