(figs. 348, 349, 350 & 351). These filamen- 

 tous pedicels in most cases exhibit a con- 

 traction just below the point of origin of the 

 spore, giving them the same appearance as 

 the pedicels of basidiospores. The spores

(Penicillium, Aspergillus), or grouped 

 in a stellate form. In the Isariacei and Stil- 

 bacei the erect ])edicels are composed of a 

 number of conjoined filaments (fig. 354) ; in 

 the other families the pedicels are simple 

 filaments. Some authors include among 

 these plants theMucorini(PHYSOMYCETEs), 

 regarding the vesicular envelope of the spores 



there as a mere veil, not a true cell producing 

 the spores in its interior. This family is of
