adopt the name as it is necessary to have some name, and we would not 

 wish to use a recent name for such a common plant. While common 

 in Europe it does not to my knowledge occur in the United States.t

LYCOPERDOX CRt'CIATUM (Plate 51 ). Peridium glo- 

 bose or usually depressed, often plicate beneath, and with a strong root. 

 The sterile base of large cells usually occupies one quarter to a third of 

 the interior. Sometimes in small specimens almost none. Cortex of 

 strong cruciate spines about 2 mm. long, which adhere together and 

 peel off in patches from the peridium. This peculiar method of cortex 

 separation is characteristic of the species. The surface of the peridium 

 after the separation of the cortex is dull, minutely furfuraceous, and 

 dark brown in color. Gleba olive, when ripe dark brown, never purple. 

 Capillitium colored, sparingly branched. Spores globose, small. 4 mic. 

 smooth. Pedicels slender, caducous. 



This plant is very rare in Europe, very common in the l/nited 

 States. In comparing the two plants we note that the diaphragm 

 separating the fertile from the sterile portion is more strongly marked 

 in the European plant. Otherwise we note no difference. Rostkovius 

 gave a characteristic illustration and we have always used his name. 

 If Dr. Hollos in digging back for an old name had contented himself 

 with stopping at something definite. Yittadini's name, marginatum. we 

 should have adopted that name for the purpose of uniformity, for 

 although Yittadini's illustration is abnormal as to shape, we are con- 

 vinced from his specimens it is the same plant. Hut when the Doctor 

 digs up Lycoperdon pratense of Per soon and Lycoperdon papillatum of 

 Schaeffer, both of them contrary to the traditions and scanty evidence 

 that exist in Europe, we cannot follow him. In digging for an old name, 

 if one wants to antedate the definite work of Yittadini and Rostkovius, 

 everything points to Lycoperdon candidum of Pcrsoon.
