the center of the upper side of the pileus. In the full-grown 
specimens the pendant pileus expanded in a horizontal plane 
eccentrically to a diameter of from 6-9 cm. but with only about 
one-fifth of the whole diameter between the side of the log and 
where the stem passes into the pileus, as shown in fig. 7. Usu- 
ally a short stem is present, not more than 1 cm. long, flattened, 
and 1 cm. in greatest diameter where it joins the pileus. The 
stem contracts so greatly in drying that the dried fructifications 
appear sessile. 
In May some íructifications matured on the upper end of 
the log. These fructifications were cup-shaped at first, becom- 
ing expanded later, and having the hymenium superior and 
the stem central. In both cases, whether the pileus was pen- 
dant and with its hymenium inferior or erect and with hymen- 
ium superior, the hymenium, fig. 8, was on the surface opposite 
or most distant from the stem. In this connection it may be 
recalled that before Hirneola was made a synonym of Auricu- 
laria on account of its development the former was distinguished 
from the latter by a superior hymenium for Hirneola and an 
inferior one for Auricularia. 
Stem and adjacent surface of pileus are minutely velvety 
with short hairs when highly magnified but to the naked eye 
have merely the dull texture of the petal of a rose. The color 
of the whole plant is somewhat shell-pink in growing specimens 
but became darker in drying, passing through shades of vin- 
&ceous, and finally became deep brownish drab of Ridgway, 
somewhat translucent, and minutely velvety. 'The hymenium 
was somewhat shining and glabrous and afforded a copious 
spore-fall of white spores. The flesh of the interior of the pileus 
was highly gelatinous, but the consistency of the whole fructi- 
fication was coriaceous and pliant as rubber. For this species 
the following name is proposed: 
Auricularia rosea Burt, n. sp. Plate 3, figs. 6-8. 
Type: in Mo. Bot. Gard. Herb. 
Fructifications gregarious, orbicular, peltate, erect or pen- 
dant by a short stem which contracts in drying—often to a 
mere point of attachment—or rarely sessile from the first, 
soft, pliant, gelatinous within, somewhat shell-pink when grow-
