Family 15. RETICULARIACE^E. 



^Ethalium composed of numerous, elongated, entirely naked,

ORDER VII. CALONEME^E. 



Walls of sporangia, spores, and capillitium usually uniformly 

 coloured in the same sporangium. Colour variable, from yellow to 

 brownish, or chestnut, more rarely olive-green, or greyish -white ; 

 capillitium usually strongly developed ; threads simple or combined 

 into a net, either entirely free, or grown to certain places of the
