LePToGIUM, Fr., Mnt., Nyl. 
1. L. FOVEOLATUM, Nyl. (No. 2 +.) 
Tunguragua. 
Spores, see Plate LVI. fig. 1. 
2. L. RETICULATUM, Mnt. (No. 3.) 
Mons Abitagua. ; 
This specimen agrees generally with the description given by Montagne and Nylander; 
but not having seen an authentic specimen, I refer it with some slight doubt. Neither 
Montagne nor Nylander have seen the spores, which in our plant are 8, colourless, ir 
dricofusiform, 5-septate ; paraphyses thick and compact; the aqueous solution of iodine 
renders the asci and paraphyses blue, the spores yellow. See Plate LVI. fig. 2. ; 
Nylander thinks that L. reticulatum, Mnt., may be only a state of his L. foveolatum 
but if I am correct in my determination, the spores and structure show it to be a 
and distinct species.
