long and 0"3 mm. broad ; outer coat white, charged with 

 roundish lime deposits, longitudinally ridged at the sides ; 

 inner wall covered with dense lime deposits, which fill up the 

 longitudinal crack in the outer wall ; spores violet-brown, 

 almost smooth, 8 /* diameter ; not quite mature. 



Physarum bogoriense, Racib. 



A gathering, on chips, consists of globose sporangia, 0'5 mm. 

 diameter, or winding flattened plasmodiocai'ps, 2*25 mm. 

 long, 0*4 mm. broad, pale ochraceous, reticulated with white 

 lines of dehiscence ; outer wall breaking away in scales or 

 revolute lobes ; inner wall gray or iridescent ; hme knots 

 white, small, generally rounded ; spores pale violet-brown, 

 minutely warted, 8 /^ diameter. In another gathering the 

 plasmodiocarps are smaller ; some have the outer wall areolated 

 and breaking away in scales, while in others it is recurved as 

 in Physarum bivalve, disclosing the grayish inner wall ; some 

 of the plasmodiocarps are flattened, others bolster-shaped. 

 The latter connects with two gatherings on dead leaves, in 

 which the plasmodiocarps are not areolated nor flattened : 

 they are up to 3 ,cm. long, yellow, winding, sometimes 

 slightly laterally compressed, 0*25 to 0*3 mm. wide, with a 

 narrow irregular raised ridge running along the top ; this 

 ridge is formed by the outer wall only ; as in Physarum bivalve, 

 dehiscence occurs along the ridge, and the outer wall separates 

 widely from the unbroken inner sporangium, but does not fall 

 off in flakes ; outer wall white internally, up to '05 mm. 

 thick, consisting of a dense deposit of minute white or yellow 

 spherical granules on the inner surface of a thin membrane ; 

 inner wall appearing gray or iridescent ; lime knots white, 

 granular, rounded or somewhat angular, with numerous 

 hyahne threads ; spores pale violet-brown, faintly warted, 8 to 

 9./^ diameter. In the general structure of the sporangium, P. 

 bogoriense would appear to be connected with P. bivalve by the 

 occurrence of forms referable to both in the same gathering.
