The sclerotia may be found in abundance in autumn on leaves and 

 twigs, especially on the trees which have been cut in summer, or on 

 broken branches. Rostrup has cultivated those sclerotia (66 '^^^ c. icon.) 

 making them produce ascomata in February and March ; in the forest 

 Rostrup found ascomata in June, and sclerotia which he placed for 

 germination in June produced ascomata in July.

Rostrup (66 "^) cultivated the sclerotia in 1863 ; they produced asco- 

 mata in June of that year and again in April of the following year, 

 as many as 25 ascomata on a single sclerotium; he names the ascomata 

 Peziza clavata Fers., Fries S. M. II ^^^, which name is possibly synony- 

 mous with ours; Rostrup also cultivated "Sclerotium durum dipsaci 

 Fries" from the receptacles of Dipsacus and succeeded in producing 

 ascomata in April; he even tried to place "Sclerotium compactum 

 helianthi de C" which had been kept dry for several years, on moist 

 sand and succeeded in making it produce ascomata. Jak. Lange also 

 cultivated sclerotia of heads of Helianthus and succeeded in making 

 them produce ascomata. 



The sclerotia belonging to this species are of very varying shape 

 and size in proportion to the tissue of the host- plant; the largest and 

 most regularly rounded shapes are found within the loosely built 

 stalks of larger herbs, in the receptacle of Compositae where it was
