A rare species only known•from the West Indies, The above 
structure is tap.on from Burt’s paper. The materiel I have is very 
scanty. 
ALEURODISCUS PEFICILLATUS (Fig. 1680).- Resupinate, effused, 
oehraceous, thin, crached when dry, the margin ednate. Spores sub- 
globose, 18-20 rile., appearing smooth to me but minutely ecbinulate 
teste Burt Paraphyses curiously shaped as shown by Burt, a few 
only penieillale at the top. It seems to me I can also see filiform 
paraphyses. A western species on Tsugae, Specimen from J. U . Grant, 
ALEURODISCUS MACR03P0RU3 (Fig. 1631).- Forming elongated, 
thin, crached, white placques on barn, and resembling a Corticium.

Cystidia rare, straight, hyaline, emerging 40-50 mic. Paraphyses

This is a species said to be common in France though only 
recently named, originally as Cortiaiun, hence the name which 
looses its meaning in Aleurodiscus. I have a specimen from Rev. 
Bourdot. 
ALEURODISCUS AURANTXUS (Fig. 1682).- Resupinate, flesh color 
to reddish yellow when fresh, drying drab. Basidia colored. Para¬ 
physes (teste Hdhnel) smooth, moniliform at top* Spores (teste 
same) finally echinulate. 
This occurs usually on gubuo in Europe and is not Known 
from the states. It was first placed on Aleurodiscus by Sohroetor.
