This species is distinguished from M. fiunctatum by its cells which 

 are nearly isodiametric and much smaller, by its larger and thicker 

 margo, theaxile fascicle of the nerve, which is colored in red and forms 

 a line generally very distinct, the larger spores (44-55//, instead of 

 30-40) and the higher peristome (0.75 millim., instead of 0.60). 

 Moreover the nerve is usually shorter than in M. punctatum.
