Glycerin 3 per cent, slight growth but no fruit. Potato plugs, good 

 growth, blue-green when young becoming gray-green above and with age 

 assumes an orange-yellow coloration on the under surface of the mat. 

 Lactose 3 per cent, same as with glycerine, slight floccose growth through- 

 out medium. Raulin's fluid, very heavy wrinlded mat that is pink at 

 first before fruiting to any extent, during latter half of cultural period 

 the fluid becomes deep wine-red. Cohn's solution, gray when young, 

 after 10 days mat becomes pink beneath, growth less than in Raulin's. 

 Lactic acid 0.9 per cent, slight growth.

Colonies orbicular, light brown, nonzonate; vegetative hyphas creeping, 

 branched, septate, hyaline, 1.3-6.6^ thick; conidiophores erect, to 2iOjU 

 high, 2-3.3/1 thick, hyaline, septate, with a verticil of 5-8 branches 

 on the summit; branches lageniform, inflated at the tip, 16-2 2 )U long; 

 conidia emerging from the apex of the branch in very long (ioo-i6o/x) 

 chains, globose, light brown, smooth, 2-3/^ in diameter.

 Penicillium terrestre n. sp. 



Colonies round, yellowish green; sterile hyphas branched, septate, hyaline, 

 2-6/i thick; conidiophores 70-3 7 5/i high, 2-4/i thick, 

 hyaline, septate, toward the top with one or two 

 primary side branches or bearing simply a verticil of 

 usually 3 primary branches; primary side branches 

 each have at the summit a verticil of 2-5 basidia, or 

 occasionally the primary side branch may bear a 

 secondary branch, both primary and secondary then 

 bearing at their summits 2-5 basidia in a verticil; 

 when only a verticil of priinary branches is borne on
