’ On the ground in spring. Esculent. 
Cup 2 inches broad, 13 inches high, externally floccoso- 
furfuraceus, light umber, darker within, mouth con- 
tracted, firm, tough, flesh not very thick; stem 4 an inch 
high, smooth, deeply, but regularly costato-lacunose ; the 
ribs branching at the top and forming reticulations on 
the outside of the cup, so as to present the appearance of 
a cluster of pillars supporting a font or roof, with fret- 
work between them (“ Eng. Flo.”). 
External cells of the cup concatenate, with their free 
extremities breaking up, so as to give a farinose appear- 
ance to the surface (Dr. Cooke, J. ¢.).
