Found in Copenhagen in dates completely filling them with a black pow- 

 dery mass. Lagerheim (03) unites this species with the above. Found in Co- 

 penhagen (May 97, Boldt, see R 99 a "2, 02 a **^ and March 09 C. H. O.).

Widely diffused on dead and decayed plants, hay etc. On hoof of horses 

 (see R 94 f ""). 



Penicillium. 



Only Penicillium Wortmanni Klecker produces the ascigerous form 

 of fruit. All other species of this genus ought to have been sta- 

 ted under Fungi imperfecti; I have, however, stated them here just as 

 the above species of Aspergillus because the ascigerous forms and the 

 conidiferous forms are not furnished with special names. Even Peni- 

 cillium crustaceum which, according to Brefeld, is able to produce 

 ascigerous fructification, is unable to do so in Denmark (see Klecker 

 03 b 6^ 06 ^'^). Rich. Westling has lately written an excellent mono- 

 graph of the green species of Penicillium (11).

Very common on bread, fruit and other food, moist vegetables etc., its 

 spores occur in the air in abundance (see E. C. H. 82 &. O. R. 08); Rostrup 

 states that he has found it in Copenhagen in a 14 per cent solution of 

 coppersulphate containing about 7 "/o of free sulphuric acid, it has also for- 

 merly been found on the same substratum in France and has been described 

 as Penicillium cupricum Trabut (see also Fetch 06).
