The four species of Cordyceps known from Japan are as follows:
CORDYCEPS GUNNII (see Synopsis of the Cordyceps of Australasia,
page 6, fig. 618). This is known from a single collection at
Museum of Paris. It is a large Australian species, and has never
been collected outside of Australia, excepting this one Japanese collection.
CORDYCEPS SOBOLIFERA (see Myc. Notes, page 529, fig.
721). This is a species of the West Indies, said to be common there,
but not known from any collection in the museums nowr . It grows
on the Cicada. A specimen was sent me from Japan by Dr. Kawamura,
the only specimen I have seen. Dr. Kawamura reports it as
common in Japan, but none of my other correspondents have met
with it.
CORDYCEPS NUTANS (see Myc. Notes, page 529, fig. 720).
This is apparently the most frequent Cordyceps in Japan. It grows
on a Hemiptera, and (excepting the next) is the only species recorded
on this bug. I have specimens from J. Umemura and also A. Yasuda,
from Japan.
CORDYCEPS TRICENTRUS (Fig. 775), FROM PROFESSOR
A. YASUDA, JAPAN. Stipe slender, 1 mm. by 6 cm. Head nodding,
smooth, \y2 mm. by 7 mm. Entire plant yellow. Perithecia
not prominent. This species grows on Tricentrus, and is
very similar to Cordyceps nutans. It differs in its host,
Tricentrus a name we have not located in any entomological
work in our library and in its color, pale yellow in all its
parts. Cordyceps nutans has a black stem below and deep
orange above, as in the club. We present a figure (Fig. 775)
made from a drawing sent us by Professor Yasuda. Also a
photograph (Fig. 776), enlarged six diameters, of the Cordyceps
club. From the figures, the species cannot be told from
Cordyceps nutans, and it grows on a
similar host. The only difference is
the color, as noted above, and which
is quite marked, according to Professor
Yasuda, and he is familiar with
both species. It is probably better,
however, to consider it as a form of
Cordyceps nutans.
ISARIA ATYPICOLA (see Letter
Fig. 775. 56, Note 257). This occurs on a
large, burrowing spider, and much resembles
to the eye a Cordyceps. Its fruit, however, is only conidial,
hence it is an Isaria. Most Isarias are supposed to be preliminary
stages of Cordyceps, and this probably is; but the Cordyceps form
has never been found. We trust those living in Japan will watch
closely for a Cordyceps, on their burrowing spider.
