Stated that this was the second recorded case of symbics 
between a liliaceous plant and a fungus. The genus Philesé 
grows in the damp humus soil of west Patagonia, and ed 
coralloid root masses. The fungus was sparingly present vd 
side the roots, also in the epidermis and exocortex, but i 
an abundant growth in the mesocortex, the cells of ese 
rapidly became filled with coiled fungoid hyphe. The 
spherical starch grains of these cells were acted om b 
action. A large amount of proteid material then app& 
the hyphe. With growth of the root extremity, the
