spores 6-7 X 40-50, but Moeller it appears had a different species. 
The genus Thamnomyces may be divided into three sections 
(four if Cooke was right) as follows: 
Section 1, stem dichotornously branched, fruiting body hollow of 
a single perithecium. 
Thamnomyces Chamissonis (spores 4 X 8-12) Fruiting body 
short, stalked. 
Thamnomyces dendroidea (spores 4-5 X 13) Fruiting body long, 
stalked. 
Thamnomyces cmnerunensis (spores 8-9 x 16-28) Fruiting body 
long, stalked. 
Section 2 (Xylobotryum in part). As Section 1 but branched com¬ 
pact and spores septate. 
Thamnomyces andinus (as Xylobotryum). 
Section 3, Stems unbranched. Fruiting body and spores as in 
Section 1. 
Thamnomyces chordalis. 
Thamnomyces fuciformis. 
THAMNOMYCES CHAMISSONIS FROM GUSTAVO PECKOLT, BRAZIL (Fig.1598 
and Fig. 1599, end of branch enlarged).- Stem rigid, black, entirely 
carbonous, repeatedly dichotornously branched, each branch terminating 
in a pair of subsessile, ovate fruiting bodies. Each fruit body is 
hollow and contains numerous spores. No trace of the asci is found 
in the mature plant. Spores mostly 4X8, oblong with obtuse equal 
ends. Thamnomyces Chamissonis was the first species of the genus nam¬ 
ed and was well figured by Chamisso from Brazil in 1820 i It is jet 
black when wet but dries slightly brownish. A pair of subsessile 
fruiting bodies terminate each branch. Moeller attributes to Thamno- 
myces Chamissonis a species which in its grosser aspect seems the 
same but must be different as he gives its spores as 40-50 mic. long. 
THAMNOMYCES CAMEEUNSNSIS FROM T. HUNTER, NEST AFRICA (Fig. 
1600 and Fig. 1601 ends of branches enlarged).- Stem rigid, carbonous 
jet black (both wet raid dry) repeatedly dichotornously branched, each 
branch terminating in a single, ovate fruit body. Spores 8-9 x 16- 
28. There are also small, subglobose, colored spores, 4-5 X 6 which 
are probably conidial. Vie received this plant fresh from ft. H. Bunt¬ 
ing, Gold Coast. Africa, and referred it to Thamnomyces Chamissonis 
(cfr. Fig* 850, # Large Pyren. page 11). A correct knowledge of the 
Brazilian plant shows it to be a different species. Of course we do 
not know with certainty that it is the same that Hennings named from 
Africa for he gave a crude figure and did net record its spores but 
we have little doubt of it. Then we received eight specimens from 
T. Hunter, West Africa. Five of these correspond exactly to Bunting's 
plant but three have In addition to the usual terminal fruit, 
axillary fruit of an apparently different type, viz. of several peri- 
thecia confluent (Fig. 1602 enlarged). At first we thought it a new 
type of Thamnomyces but finally concluded that these axillary fruit 
were not normal and they nor appear to me to have grown when the 
plant had been injured. On general appearance the African plant 
appears the same as the Brazilian, but a close comparison shows.two 
marked differences, the way the fruit are borne and the great differ¬ 
ence in the spore size. Thamnomyces earneruxiensis of Africa is tne
