description of C. tigrincllus lioud., which is said lo be very 

 close to C. Friesii. Ouelet described C. Friesii as growing 

 on dead iiut still erect stems of grasses. Lange finds it 

 typically (jn dead grass, and also a form on dead Phragmites 

 straw, and another form on bits of straw from horse- 

 droppings. C. ligrinellus Boud. grew on dead erect stems 

 of Carcx, and has been recorded in this country both on 

 Carex and on Jiincus.f All these forms thus agree in growing 

 on dead erect stems of grasses, sedges, or rushes, in damp 

 places. They agree closely also in macro- and microscopic 

 characters, the chief point distinguishing ligrinellus from 

 Friesii being that the flecks on the pileus are deep brown 

 instead of white. As in my specimens the colour of the 

 lomentum varied from white to rust-brown, it seems probable 

 I hat C. ligrinellus and C. Friesii are hardly specifically 

 distinct. The name Friesii is used as being the earlier. 



Bulbitius tener Berk, and (lulera rubiginosa Fr. 



In the same hollow where the Coprinus Friesii grew, there 

 occurred two small brown-spored Agarics, Bolbitius tener 

 fJerk. (distinguished from the more common species of 

 Bolbitius by its while and less fragile pileus), and Cudcra 

 rubiginosa Fr, 



These grew directly from the sand, and were not connected 

 in any way with an^^ phanerogamic plant. In the course 

 of digging up some specimens it was noticed that the top 

 layer of sand came away easily as a flat crust about |in. 

 in thickness. The fungi had no rooting base, the stipes end- 

 ing abruptly in this upper crust of sand. Closer examination 

 showed that the crust was slightly tinged green, and it was 

 subsequentlv found that this colour was due to innumerable 

 minute algae with which the sand was permeated. The algal 

 laver consisted mainly of a species of Oscillaria, but a few 

 unicellular green forms were also present. 



These two species of Agarics, therefore, must have 

 subsisted practicallv entirely on the small amount of humus 

 derived from the algal crust. The Galera grew gregariously, 

 in considerable quantity. Bolbitius tener was also 

 represented bv a number of specimens, but was not so 

 abundant as Gal era rubiginosa.
