SCLERODERMATACEAE 169 



that can be matched by our plants, asperulate, 6.6-18/i, most about ll-14/i (pi. 120, 

 fig. 12), but the surface, while cracked into areas, is not dotted with small separated 

 scales of a different color. Lloyd uses S. tcnerum for our U. S. American plant, and the 

 Cuban plant certainly represents ours in the tropics. The types at Kew (kindly loaned 

 us by the director) consist of two good plants. One has the surface of our plants; 

 the other has more pronounced warts (pi. 95). The spores of both are the same and are 

 like the American form except for the average smaller size, 8-11/x, most about 8.5-10/x 

 (pi. 120, fig. S). They are almost exactly the size of the spores of S. cepa. We have 

 fortunately been able to find a good name for our form of the plant as proved by an 

 authentic specimen of 5. lycoperdoides in Michener's herbarium from the Schweinitz 

 Herbarium. The specimen is in good condition and shows all the characters of our 

 plants, the spores 10-15/i thick, covered with short or long, sharp spines which become 

 clear only after a treatment of K.OH has dissolved away the gelatinous, granular 

 material between them. Lloyd did not find the species represented in the Schweinitz 

 Herbarium in Philadelphia and so hesitated to use the name. There is, however, a 

 fragment of this in the Schweinitz Herbarium which has the same spores as the plant 

 above mentioned (10.5— 13ju)- There are also fragments from the Schweinitz Herbarium 

 in the Curtis Herbarium labelled S. lycoperdoides which seem to be the same. The 

 spore structure of S\ lycoperdoides is as in 5. cepa (No. 3109) except that the spores in the 

 present species are considerably larger and more variable. For a supposed variety of 

 this species see Peck, Rept. N. Y. St. Mus. 53: 848, pi. B, figs. 8-12. 1899.
