Fungi terrestres from North-East Greenland. 145 



namely, is greyish chocolate-brown, and the spores are slightly 

 warled (45— 55// diam., light-yellow); further, the threads of the 

 capillitium have nearly the same diameter as the spores. These 

 microscopic characters point towards C. cijathiformis, without how- 

 ever permitting identification with this species; for this also the sculp- 

 ture of the periderm and the light colour stand in the way. 



I then sent the specimen from the Liverpool Coast (A), as also 

 a true C. cyatbiformis, (No. 1906) to Dr. Hollös, who verj' kindly 

 subjected these fungi to a closer investigation and returned them 

 with the following remarks: „Exemplar A ist entschieden kein Calva- 



tia caelata (Bull.) Morg Auch nicht Calvatia cyathiformis (Bosc) 



Morg. — Ich kenne den Pilz nicht. In meiner reichen Sammlung 

 befindet sich kein solches Exemplar, mit dem ich Exempl. A ver- 

 gleichen könnte." 



On an accompanying, analytical drawing Dr. Hollös has written: 

 Calvatia sp.? — and in this genus the fungus should certainly be 

 placed. It seems, from the information given, to be rather widely 

 distributed in East Greenland.
