PENICELLIUM FTJNICTTLOSUM. 69 



Habitat, in fungie putreacentibus, Boletis, Polyporis; Storre, Conn.; Paris, Gallia. 



Cultivated in gelatin or potato agar, green or yellowish green, becoming gray-green 

 or gmy when old (remaining green in sugar media . H spreading more rapidly 



in young cultures by aerial stolons than by submerged hi phse (i. e., the submerged 

 mycelium Beems to arise from the aerial rather than vice versa ; reverse of colony nol 

 colored or partly yellow; conidiophores arising as short branches i LOO/i or less in length l 

 from aerial hyphse, or arising separately 300/i or more in length especially at the mar- 

 gins of older colonies; conidial fructification 10 s n more rarely up to 170". in Length, 

 composed of Bhort appressed branches and numerous conidiiferous cells densely 

 crowded at the base bearing very loosely divergenl chains of conidia; Bometimes the 

 lowesl branch diverges bo thai the fructification appears double; conidiiferous cells 

 10 by ■>;•; conidia Blightly elliptical or globose, 2.8 3.4/i, Bmooth, yellowish green in 

 mass, almost hyaline by transmitted light; colonies liquefy gelatin \ ery rapidly, with 

 u strong alkaline reaction to litmus. 



Habitat, decaying fungi, Boleti, Polypori; cultures from milk and ensilage. Col- 

 lected repeatedly at Storrs, Conn.; once upon decaying Boh tus scaber at the Jardin des 

 Plantes in Paris, hence probably widely distributed. The stolon-producing character 

 is so easily seen and so characteristic of this species as to seem adequate to distinguish 

 it from all other species studied. This has been observed upon a decaying Boletus 

 with a hand lens. 



CULTURAL DATA.

 old cultures; reverse, not colored (or slight ly yellow i; color in media, none or slight.
