either on the co-type or on an authentic specimen from Dr. Mich- 

 ener in the Farlow Herbarium or on a plant sent from Kew by 

 Massee (in New York Botanical Garden) which was probably 

 taken from Berkeley's part of the type. Both of those last men- 

 tioned have the exact appearance of the Curtis specimen. The 

 species resembles C. byssiseda in the dry state except that it is 

 larger and apparently emerges through rotting leaves instead of 

 being seated upon them. It is about the size of small C. stricta, 

 but the spores are certainly extremely scarce in comparison with 

 the universally abundant spores on dried plants of C. stricta, and 

 the hymenium is distinctly thinner. That it was growing among 

 leaves instead of on wood is probably of small consequence. In 

 American herbaria most plants under the name Lachnocladium 

 Michencri are C. stricta or C. apiculata and Bresadola has deter- 

 mined plants of the latter species as L. Michencri, and in his dis- 

 cussion of C. byssiseda (Ann. Myc. 1 : 112. 1903) he considers C. 

 leucotephra, C. fragrans, C. pinophila, and L. Michencri as the 

 same and equal to C. byssiseda. The spores of the first two are 

 much shorter than of C. byssiseda and of different form. We find 

 at the New York Botanical Garden a plant from Newfield, N. J., 

 labelled C. leucotephra by Ellis which was examined by Dr. Farlow 

 and determined by him as L. Michencri. The plant is in reality 

 what we are calling C. gracilis, the spores agreeing exactly with 

 that species in size and appearance, smooth, 3-3.5 x 5-5. 5(i. 



Lachnocladium Atkinsonii Bres. is very likely the present 

 species or C. apiculata. There is nothing in the description to 

 exclude it from either. We cannot find the type at Ithaca, and the 

 species is not represented in the Bresadola Herbarium at Stock- 

 holm. There seems to be no doubt that Atkinson's L. odoratum 

 is also the same. We have not been able to find the type at Ithaca, 

 but there are no discrepancies in the description and the distinctive 

 characters are brought out, the tomentose, sterile lines being char- 

 acteristic of C. stricta. The spore measurements given by Atkin- 

 son (3.5-4.5 x 7-10[i.) agree. The sweet odor (suaveolens) noted 

 by Atkinson may mean the same thing as the anise odor found in 

 Beardslee's Asheville plant. 



From the description of C. Berkeleyi Mont. (Syll. Crypt., p. 

 180. 1856), it may be the same as this. Saccardo says that the
