We have not seen this except in the dry state, but have exam- 

 ined the type at Albany, two other collections from the type lo- 

 cality sent us and the N. Y. Botanical Garden by Miss Hibbard, 

 and also two collections sent by her from Newfane, Vermont. 

 The types are as large as any of the other specimens, brittle, tan 

 to cream color, the base rooting and branching at or below the 

 ground, less than a cm. thick, a little scurfy tomentose below but 

 not so much so as C. Kunsei, which seems to be a near relative. 

 The spores are small, but distinctly larger than in the latter 

 (3.4_4x4_5.2(ji) and are shaped much as in C. pulchra, the min- 

 ute, warty spines much more numerous than in C. Kunsei. Ac- 

 cording to Miss Hibbard the spores are white. Other differences 

 from C. Kunzei are larger size and greater fragility. 



We believe that this is the same as C. lento fragilis Atk., the 

 spores being the same and the descriptions agreeing in all impor- 

 tant respects. However, we have not been able to compare an 

 authentic specimen of the latter side by side with this, so are re- 

 taining both for the present. It is also possible that this is C. 

 elongata Britz. His entire description is, "Entirely white; spores 

 3-4{x, very rough, with fine and short spines." His figure 50 is 

 like our plants. 



In size, form and color in the dry state C. cineroides is similar, 

 but that has very different spores. Peck's description of C. 

 subcaespitosa is as follows : 



"Forming dense tufts 7.5-12.5 cm. tall, fragile, white or whit- 

 ish, the stems united at the base, three to five times dichotomously 

 divided, the terminal branchlets obtuse or subacute, both stems and 

 branches solid, soft, becoming thinner and flattened or angular in 

 drying, flesh white, taste mild; spores broadly ellipsoid or sub- 

 globose, 4-5 x 3-4(x. Ground. Ellis. Mass. September."
