I have not seen a specimen of Marasmius tricIiorrJiizus Speg., 
but as Theissen does not mention any “ collar/’ it would 
appear to differ in that respect from M. equicrinis. The 
identification of M, polycladus with M. equicHnis is certainly 
incorrect. A specimen of the former from Montagne, in the 
Kew Herbarium, arises from rather coarse mycelium, 0*4-0 *5 
mm. diameter, and closely resembles M. obscuratus ; it differs 
from the latter in having a glabrous stalk. 
The type specimen of Marasmius multiceps B. & C. at Kew 
closely resembles that of M. polycladus, but it was said to 
differ in the colour of the pileus, the former being white and 
the latter brown becoming purple. Marasmius Mppiochætes 
was said by Berkeley to be near M. polycladus, but the t5rpe 
specimen shows that it is a species with a small pileus and 
very long stalks, not a species which arises from a rhizomor- 
phoid mycelium, as far as the specimen indicates. Maras- 
mius tomentellus B. & C. from Cuba is another species which 
possesses rhizomorphoid mycelium, but its mycelium is 
clothed with white spreading hairs, which are apparently 
deciduous ; it is not M. sarmentosus, since the pileus is not 
shaggy. M. erumpens Mass., which was said to be ‘‘ M. sar- 
mentoso affinis,” bears no resemblance to that species ; it has 
no rhizomorphoid mycelium, and its pileus is glabrous. 
Without an inspection of the type specimens it is impossible 
to come to any valid conclusions concerning the other similar 
species of Marasmius which have been described from various 
parts of the Tropics. The following descriptions are quoted 
for reference, with some notes which they suggest. The 
Ceylon and Indian specimens would appear to indicate that 
the mycelium of any one species is constant in size and 
appearance.
