COMMON BROWN MOULD. 



FIG. 1. THE MUCOE PLANT PRODUCED FROM A CONIDIUM. Showing 



Branched hypha. 



Erect hypha (Gr. liyplie, a weaving) terminating in a minute enlargement the sporangium. 

 FIG. 2. Showing 



End of erect hypha. 



Columella (L. a little column). 



Terminal cell, conidia case, or sporangium (Gr. spora, a seed; angeion, a vessel). 



Wall of sporangium with crystals of oxalato of lime, 



Spores or a endo-conidia (Gr. entlon, within ; Iconis, dust). 

 FIG. 3. Showing 



Burst conidia-case or sporangium. 



Collar, the remains of the wall of sporangium. 



Endo-conidia or spores. 

 FIG. 4. Showing 



The conidium germinating and producing a branched hypha, which ultimately develops into tho 



form shown in fig. 1. 

 FIG. 5. Showing 



Portion of branched hypha with protoplasm removed. 



No septa. 

 FIG. C. Showing 



Portion of old submerged hypha, breaking up into distinct joints the Chlamydospores (Gr. 

 chlamys, a coat ; spora, a seed) or Mucor-torulse, each containing a vacuole. 



Note. Vacuolated protoplasm and septum. 

 FIG. 7. THE SEXUAL PROCESS 



a fy b. Two distinct processes given off from the hyphse. 



c. Terminal cell separated off from each process. 



d. Union of the two terminal cells to form a zygospore (Gr. zugos, a yoke ; spora, a seed). Since 



the uniting elements closely resemble one another the process is called conjugation.
