lawny; stem elongated, dotted with red, not reticulate, red 

 within at the base and partially elsewhere ; tubes free.

 opaque, dry, purple-red ; stem stout, variegated with purple 

 veins or dots ; tubes minute, nearly free, yellow, changing to 

 green, orifice purple-orange. — Kromb. t. 37. /. 12-] 5.
