TYLOSTOMA MAMMOSUM (Fig. 5).—There is one collection at 
Kew “White River 1870” which I think is the same as the European spe¬ 
cies. This species is the most common one in Europe and the only one 
known to occur in England. 
TYLOSTOMA LEPROSUM.—I have seen only a very poor speci¬ 
men. It is not as “spotted” as its name indicates. The “lurid umber mealy 
scurf” is the ordinary veil that all Tylostomas have which in this specimen 
happens to pull off somewhat in patches. 
TYLOSTOMA WIGHTII—Was based on a plant from India. I have 
seen no specimen purporting to come from Australia. 
TYLOSTOMA FIMBRIATUM.—There are specimens so labeled 
from Swan River, but their mouths do not show. Notwithstanding Fi S* 5 * 
a recent “picture” has been made, showing the supposed “fimbriate mouth” 
character of this European species, I have been unable to find in Museums any 
specimen from Europe with such a mouth, and I question if such a species exists 
in Europe. There are species with such mouths in South America. 
TYLOSTOMA ALBUM.—The specimen on which this is based is old, weath¬ 
ered, and bleached out. It has a large head and a short thick stalk, but I could not 
make out its mouth characters. 
TYLOSTOMA PULCHELLUM.—Said to be a minute species that grows on 
branches(?). It was described by Saccardo (Bull. Soc. Myc. 89, p. 118). I have 
seen no specimens. 
We have received Tylostomas very scantily from our Australian correspon¬ 
dents. A single specimen from F. M. Reader, Victoria, is we think, Tylostoma 
Purpusii recently described from the Western United States. A specimen from 
J. G. O. Tepper has a protruding mouth and would ordinarily be referred to Tylos¬ 
toma mammosum of Europe, but it is not that species. 
THE GENUS CHLAMYDOPUS. 
Peridium globose, seated on the broad, con¬ 
cave apex of the stem. Capillitium and spores as 
in the genus Tylostoma. Stipe long, thick and con¬ 
cave at the apex tapering to the base. Volva per¬ 
sistent as a cup at base of plant (usually absent 
in herbarium specimens.) 
The genus Chlamydopus can well be (as it is 
by some authors) classed with the genus Tylostoma. 
It differs in the attachment of the peridium to the 
stem. In Chlamydopus the peridium is seated on 
the broad, concave apex of the stem. In Tylostoma 
the stem is inserted into a “socket” in the base of 
the peridium. 
CHLAMYDOPUS MEYENIANUS. — But 
one species is known originally from Peru, but 
found also in Western United States (cfr. Myc. 
Notes, p 134, plate 10). But onespecimen (fig. 6) 
is known from Australia, collected Gascoyne River 
by Mrs Gribble and described (Grev. 15-94) as 
Tylostoma maximum.
