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, Calvatia-Vike; 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, stalky-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 — Q /j. 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 

 Caluatia cyathiformis, and the well-known specialist on the Gastero- 

 myceteae, Dr. Ladislaus Hollos of Hungary, to w^hom 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 С Kruuse and published in Ro- 

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

 p. 115, under the name of Lycoperdon favosnm (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 Geaster-Uke, 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-

 (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 Oudemansii.
