  Agakicus 
  (Pholiota) 
  detersibilis 
  n. 
  sp. 
  

  

  Pileus 
  hemispherical 
  or 
  convex, 
  thin, 
  densely 
  coated 
  with 
  

   small 
  erect 
  pyramidal 
  or 
  spinulose 
  scales, 
  ochraceous-brown; 
  

   lamellae 
  broad, 
  plane, 
  close, 
  reaching 
  the 
  stem, 
  slightly 
  

   attached, 
  pallid 
  then 
  cinnamon-brown 
  ; 
  stem 
  equal, 
  stuffed 
  

   or 
  hollow, 
  squamulose 
  below 
  the 
  obsolete 
  ring, 
  colored 
  like 
  

   the 
  pileus, 
  often 
  curved 
  ; 
  spores 
  unequally 
  elliptical, 
  .0003'- 
  

   .00035 
  / 
  long. 
  

  

  Plant 
  about 
  1'

  The 
  small 
  soft 
  scales 
  are 
  rubbed 
  off 
  easily, 
  whence 
  the 
  

   specific 
  name. 
  I 
  suspect 
  that 
  under 
  more 
  favorable 
  condi- 
  

   tions 
  the 
  plant 
  may 
  grow 
  considerably 
  larger 
  than 
  the 
  

   dimensions 
  given.

  Pileus 
  fleshy, 
  convex

  sometimes 
  gibbous 
  

   or 
  broadly 
  umbonate, 
  rarely 
  centrally 
  depressed, 
  glabrous 
  

   grayish 
  or

  whitish

   becoming

  flexuous,

   or

  October. 
  

  

  This 
  interesting 
  species 
  is 
  dedicated 
  to 
  Mr. 
  V. 
  Colvin, 
  to 
  

   whom 
  is 
  due 
  the 
  credit 
  of 
  its 
  discovery. 
  Its 
  habitat 
  is 
  pecu- 
  

   liar, 
  being 
  the 
  clear 
  drifting 
  sand 
  of 
  the 
  plains 
  west 
  of 
  

   Albany. 
  The 
  mycelium 
  binds 
  the 
  sand 
  together 
  in 
  a 
  mass 
  

   which 
  adheres 
  to 
  the 
  base 
  of 
  the 
  stem. 
  A 
  cricket 
  was 
  

   observed 
  feeding 
  upon 
  the 
  pileus 
  of 
  a 
  small 
  specimen.

  the

  tinge, 
  strongly

  close, 
  narrow, 
  reaching 
  the

  brown 
  then 
  black;

  equal, 
  hollow, 
  smooth 
  or

  pulverulent,
