CLAVARIA MUCIDA Pers. —This pretty little species has an interest- 
ing habit that I have seen referred. to only by Morgan,‘ who describes 
: it as “usually growing on a thin 
greenish stratum, Chlorococcus.” 
I have often found this plant, and 
it has always been associated with 
this alga.> It generally grows on 
dead, soggy wood, but often also 
on alga-covered soil. The habit 
is shown in fg. 76. Atkinson 
describes and gives a photograph 
of C. muctda,® but does not men- 
tion its association with the alga. 
Neither does Hennings in Engler& 
Prantl’s Phanzenfamilien, who says 
in reference to its habit, “‘ Auf fau- 
lenden Holze, seltener auf Erde.” 
If the basal part of the fungus 
and the substratum be cut in paraf- 
fin or teased under the micro- 
scope, it will be seen that the 
delicate hyphae ramify from the 
base of the stalk and pass out in 
all directions among the alga cells., 
figure 17 illustrates the relation 
between alga and fungus. The 
hyphae do not enter the alga and 
have no haustoria, but show about 
the same loose relation with the 
alga as in the case of the lichen, 
SS Collema. From its constant occur- 
rence and close association with 
this alga there seems scarcely a 
doubt that Clavaria mucida is in 
the initial stages of becoming a 
basidiomycetous lichen.
