Imperfectly Known Species of Australia. 
Secotium acuminatum is a very common plant in the United States, North¬ 
ern Africa. Hungary and Russia, but I do not feel assured of its occurrence Jin 
Australia from the small fragments so labeled that I have seen. The determination 
is very doubtful. 
Secotium scabrosum (Grev. 20-35). All that is known of this plant is a 
single head with the stem gone. It has a close resemblance to erythrocephalum, 
but has larger, rough spores. 
Secotium virescens (Grev. 19-47) is based on the merest fragment, 
Secotium Gunnii (Grev. 19-96) is based on the merest fragment and is prob¬ 
ably I think Secotium coarctatum although the spores are a little larger. 
Secotium Rodwayi (Kew Bull. 01-158). These little specimens are about the 
size of peas. Said to be subterranean and only exposed when thrown up by mar¬ 
supials. The spores, almost globose and rough are quite peculiar. In these speci¬ 
mens they are almost hyaline. I think the plants are not mature. 
Secotium lilacense (N. Zea. Flor.) is based on a lilac colored figure. It is 
said to grow on wood. There are no specimens known. 
Secotium leucocephalum (Grev. 19-95). These specimens were collected by 
Berggren in New Zealand and at first supposed to be pale forms of S. erythroceph¬ 
alum, which they closely resemble in general appearance. They w T ere separated 
when it was noticed that they had rough spores. I did not get a photograph 
of them. I should call the color pale, but not white. 
THE GENUS CLAVOGASTER. 
Plant clavate, stipitate. Peridium single, dehiscing (?) Colu¬ 
mella (?). Gleba of permanent cells. Spores smooth, oblong, pedi¬ 
cellate. 
CLAVOGASTER NOVO-ZELANDICUS. — This 
plant is known from a single half specimen (fig 4) col¬ 
lected at Auckland New Zealand by Dr. Hausler and pre¬ 
served at Berlin. It has been claimed that the plant be¬ 
longs to the genus Cauloglossum* and the name Caulo- 
glossum novo-zelandicum proposed. It seems to me the 
plant is closer to the genus Secotium, having the same 
spores and gleba. I could not tell whether it has a colu¬ 
mella or not. As long as the plant is known from such 
scanty material, the name might just as well be left as it 
is, until more material is found. It would be recognized 
at once by its shape. 
THE GENUS TYLOSTOMA. 
Peridium globose, furnished with a protruding tubular mouth or 
opening irregularly, stipitate. At the base the peridium has a sort of 
“socket” into which the stipe is inserted. Gleba of branched some¬ 
times septate threads and abundant, globose spores. 
The genus Tylostoma is wide spread over the earth and the 
species are not well worked out. The Australian collections are very 
scanty, and I feel, very imperfectly known. I shall not attempt a 
description from such material. 
* A genus known only from the United States.
