As the above diagnosis shows (see also Plate IX), this fungus 

 has a very characteristic external appearance, not unlike certain 

 forms of Scleroderma aurantium (Vaill.) Pers.' The specimens collected 

 were unripe, but on going through the collections of the Botanical Mu- 

 seum of Copenhagen in order if possible to find material for comparison, 

 I was successful in obtaining a ripe specimen of the fungus, collected 

 on the Liverpool Coast, Hurry Inlet (C. Kruuse). The latter is 

 noted in Rostrup's Fungi Groenlandiae orientalis etc., Medd. om 

 Grønland XXX, p. 115, under the name of Lycoperdon favosum (Rostk.) 

 Bonord. . This last species seems from the description hardly distinct 

 from Calvatia caelata (Bull.) Morg., and in his work "Die Gastero- 

 myceten Ungarns" p. 163, Hollös also gives the two species as syno- 

 nyms. — It is not possible now, however, to bring the above-de- 

 scribed species in under the true Calvatia caelata; the gleba-mass, 



^ lu "Tillæg til Grønlands Svampe", Medd. om Grønland III p. 601, Rostrup states, 

 that Scleroderma vulgare Fr. is "common in heaths", citing a note of N. Hartz, 

 written on a label to a specimen from Vajgattet. The sjjecimen in question, 

 however, is no Scleroderma, but belongs to the Lycoperdaceae and is most 

 likely nothing but a 3'oung Calvatia arctica. After this Scleroderma vulgare 

 Fr. (^= 5. aurantium (Vaill.) Pers.j is not recorded from the East coast.
