"Spores 0.014— 15 long, 0.007—8 mm. broad." {Nyl.) "Spores 0.012—18 

 mm. long, 0.006—7 mm. broad." (T. M. Fr.) " .003—004 in. long, by .00125 

 — 0015 in. broad." (Mudd.) I blue, asci-brown. Spores .0165 mm. long, 

 .008 mm. broad. 



27. L. trochodes, Tayl. rust-brown thin, leproso-tartareous, 

 slightly rimose, indeterminate ; apothecia black, small, adnate, 

 roundish, uneven, centrally umbonate or tuberculate, margin tumid,

 gelatina hymenea I pale-bluish and then tawny-vinous-red.
