This fungus is very cosmopolitan in its distribution (Asia, Africa, 

 America, Europe) and also occurs in this country, mostly on heath 

 and downs. — Of the specimens brought home No. 1906 is about to 

 shed its spores and it is distinctly seen, that the brown, chequered 

 periderm is bursting irregularly, Caluatia-like; in the other specimens, 

 which probably have wintered, only the bowl-shaped basal part 

 remains; in No. 79 this has a diameter of ca. 7 cm. All the speci- 

 mens are almost sessile, stalkj^-contracted below and with wrinkled- 

 grooved basal part. The spore-mass is dark-brownish, with purple 

 shade; under the microscope the spores are distinctly warted, some- 

 times with a small pedicel, yellowish brown, 5—6« diam.; threads 

 of the capillitium have almost the same diameter as the spores and 

 a slightly darker colour. The loose tissue in the quite weakly 

 developed, sterile foot-part has a lilac sheen. There could scarcely 

 be any doubt from these characters, that these fungi belonged to 

 Calvatia cyathiformis^ and the well-known specialist on the Gastero- 

 myceteae. Dr. Ladislaus Hollös of Hungary, to whom I sent No. 

 1906, has also confirmed my determination of that specimen. 



On going through the East Greenland collections in the Botanical 

 Museum of Copenhagen I came across a specimen of the above-mentioned 

 species, collected at Cape Dalton by C. Kruuse and published in Ro- 

 STRUP's "Fungi Grocnlandiae orientalis . . . ." in Medd. om Grønland XXX, 

 p. 115, under the name of Lycoperdon favosum (Rostk.) Bonord^. 

 The specimen in question consists only of the persistent basal part 

 of the fungus, which in this case is but little typical, almost disc- 

 shaped and with Geas/er-like, retroverted lobes on the margin. Fur- 

 ther, the colour is lighter than the type. A section through the 

 (short and but little distinct) stalk of the fruit-body shows, however, 

 the loose, lilac-coloured tissue which is so characteristic of C. cya- 



' Bot. Zeit. 1857, p. 595; Sacc. Syll. VII p. 121. In Bot. Centralbl. 1902, Beil. p. 4 

 (extra) Oudemans has given the same specific name to a newly founded species; 

 according to a generally applied rule this last species should be called Lycoper- 

 don Oudeniansii.
