representatives of Scopoli’s original species and are not to be con- 
founded with Æ. caput-ursi Fr. and that the plants here described 
as H. laciniatum Leers. are not H. coralloides Scop. will be evi- 
dent from the following considerations : (1) Scopoli in his origi- 
. nal description * said, “ extremis ramulis teretibus, subulatis recte 
deorsum descendentibus." This conveys distinctly the idea that 
the pendent teeth are at the ends of the branches. (2) Again in 
a later work f he says, “ Duas icones possideo, quarum una est 
stipes albus, horizontalis, fere semipedalis, digitum crassus divisus 
in ramos teretes, subadscendentes, ramossimos ; ultimis ramus 
modice deflexis et emittentibus aculeos concolores, duas et tres lineas 
longos. Altera figura est cespes subovatus, pariter albus, crebris 
ramis instructus, quorum apices aculeis etiam semiuncialibus, per- 
pendicularibus et fasciculatis terminati sunt." (Italics ours.) This 
likewise conveys the impression that the teeth are chiefly at the 
ends of the branches. Тһе latter part of the account also con- 
tains a brief description of what became later 77. caput-ursi Fries 
and it is evident that Scopoli associated the two forms as one 
species, differing chiefly in the character of the body and length 
of the teeth. Іп 1863 Fries separated the latter form as 77. caput- 
ursi and remarked in his description that the periphery of the 
tubercle was broken up into little branches “ ultimis H. corallo- 
idis haud absimiles." Moreover, in his figures of the two plants 
he clearly represents in 77. coralloides Scop. a plant whose ulti- 
mate branches and the arrangement of the teeth are essentially 
the same as his figure of H. caput-ursi. 
The plants here discussed are among the most beautiful of the 
fungi. Their snowy masses of intricate branches standing up 
from some old log appear like the most delicate frost work. 
Their beauty naturally attracted the earliest mycologists and led 
to their being noted among the early records of fungi. Тһе first 
authentic record we have is that of Steerbeck in 1675.1 He cites 
Clusius 1601 but the plant figured by Clusius appears more prob- 
ably some species of Clavaria.
