var. Jcutuensis (P. Henn.) v. Holm, is distinguished from the type by its 
hyphae 3-3 5 fx thick, hyphopodia 10-13 /a long and spores 18-20 x S-9 /m. 
Theissen had not seen the type specimen of A. Jcutuensis, but quoted von 
Hohnel's original description. I am unable to distinguish between these 
two forms ; the spores vary from 18-23 jx in length and from 8-11 fx in 
breadth ; sometimes the mycelium is fairly stout, 4-5 /x thick, with rather 
short hyphopodia (8-10 ft long) ; in other cases the mycelium is more 
slender, 3-3*5 /x thick, with hyphopodia 10-13 /x long. Not infrequently all 
these characters can be met with on one leaf, and there is, within the limits 
indicated, considerable variation in the dimensions of the hyphae, hyphopodia 
and spores. I have therefore included all the collections examined in the 
species A. Combreti without attempting to distinguish varieties. 
4. Asterina Peglerae Doidge, sp. nov. 
Plate XIII, fig. 9. Slide XI, 20. 
Hypophyllous, forming thin, spreading black areas of irregular form. 
Hyphae fuscous, very slender, 3 '5-4 jx thick, branching irregularly and 
anastomosing ; hyphopodia alternate or unilateral, 10-15 x 6-10 /x, stipitate, 
stipe usually cylindrical, equal in thickness to the hyphae, and from 3-10 fx 
long, but occasionally septate or gibbous (see A. j^eraffinis), terminal cell 
irregularly 2-3-lobed, and frequently uncinate. Thyriothecia numerous, 
scattered, light brown, flattened-hemispherical, 110-160 /x diam., composed 
of radiating hyphae 2'5-3 /x thick ; these are not straight but more or less 
undulating ; margin fimbriate ; dehiscence irregular, then stellate. Asci 
aparaphysate, sub-spherical, 45-50 x 43-45 /x, 8-spored. Spores conglobate, 
2 -celled, constricted, upper loculus larger, very opaque when mature, 
epispore ciliate, 23-28 x 13-16'5/x. 
On leaves of Rhus ? sp., Kentani, 6/9/15, Pegler (Pegler, 2354), 9130. 
The determination of the host is uncertain as Miss Pegler has never 
found this plant in flower. It is a small shrub with trifoliate leaves. 
The hyaline spores in the immature ascus of this species of Asterina are 
quite smooth, but on the spores which are just turning colour there are 
often bristles up to 3 /x long ; the epispore is pronouncedly ciliate at maturity, 
but never has bristles so long as those on the ripening spore.
