Fructification effused, indeterminate, at first pure white, 

 becoming yellowish with age, adherent. Subiculum very 



thin, at first pruinose, later waxy and 

 cracked. Granules at first very fine, 

 giving a mealy appearance, later 

 more wartlike, or at times even de- 

 veloping into short spines. Basidia 

 clavate, 15x4/^, with 4-6 (-8) curved 

 sterigmata, 2-3/x long. Spores 

 elliptical, one side flattened, 4 x 2/x. 

 Grandinia Brinkmanni Hyphae indistinct, soon, collapsing, 

 Bourd. & Galz. up to 4/i in diameter, septate, with 



a, Basidium; b, Spores; clamp connections. The flesh con- 

 c, Hyphae x 850. tains numerous crystals of calcium 



oxalate.

Recognisable by its finely granular appearance with 

 scanty subiculum, spores, and abundance of crystals in the 

 tissue.

This is the plant the structure of which was described in 

 these IVansactions for 1910, p. 280, under the name (irandinia 

 viucida. It was always referred by Berkelev to G. mucida, 

 but according to Bresadola it agrees undoubtedly with Fries' 

 H. subtile, and is the same as H. bicolor. 



The peculiar microscopic characters have also been pointed 

 out by von Hohnel, in an article which was overlooked at 

 the time the 1910 note was written.*
