Pileus 8-16 mm broad; stem 2.5-5 cni l° n g> 2_ 3 mm thick. 



Swamps. Ellis, Mass. October. Airs E. B. Blackford. 



Closely allied to Cortinarius acutus (Pers.) Fr., from 

 which it differs in the darker color of the young moist pileus and 

 whiter color of the mature dry pileus, the white color of the young 

 stem, the adnexed lamellae, and specially by the larger spores and 

 absence of striae from the moist pileus. This may be the plant 

 mentioned in Sylloge as a variety of Cortinarius acutus 

 (Pers.) Fr.

Caespites 2.5-4 cm alti, dense et subdichotome ramosissimi, rami 

 tenues, numerosi, compressi, quum humidi lavenduli, sicci, palli- 

 diores pruinosique, ramuli ultimi saepe bidentati ; sporae ellipsoi- 

 deae, 6-8 x 3-4 . 



Clavaria pallescens 



Clubs simple, loosely cespitose or gregarious, 2.5-4 cm tall, clav-
