ish, rigid, not emitting seeds when lying upon paper. In its 
young state it is gelatinous like a Boletus. Mr. Stacxnouss. 
This species has been inyolved in much confusion, chiefly arising 
from its different appearance at different ages. Mr. Stackhouse 
sent me a young plant in its gelatinous state, which accorded, as 
he observed, with Fl. dan. 776. 1; the pileus being white and 
the gills a rich deep saffron colour. Bulliard 340, the lower 
figures, seem the same plant when it has just attained its firm 
texture ; the colour of the gills darker and more of a purple ~ 
cast. The other figures represent the plant in its older states, 
and of very different sizes, the colour of the gills being then a 
reddish brown, and the pileus somewhat paler but with wavy 
circular streaks of a darker hue. ‘The figures in Bulliard 394 
are very exact representations of the specimens now before me. 
It sometimes grows to the size of one’s hand, enlarging by pro. 
liferous offsets from the edges, each offset having its own proper 
central point to which its gills are directed ; but in this case the 
gills in the centre of the aggregate plant become extremely con- 
voluted and irregularly branched. :
