Plate XVI, fig. 31. Slides XXIII, 11 ; XXIV, 13. 
Epiphyllous, effuse ; mycelium brown, consisting of sinuous liypliae 
5-6 /X thick, cells 24-30 /x long, branching irregular, hyphae anastomosing to 
form a network; hyphopodia 2-celled, not lobed, erect, straight or uncinate, 
opposite or alternate, 12-20 x 5-6 jx. Thyriothecia numerous, opaque, 
hemispherical, 130-170 /x diam., composed of radiating hyphae 3-4 jtx thick, 
central cells 3'5-4 n long, peripheral cells longer, margin fimbriate. Asci 
aparaphysate, spherical or ovate, 35-45 /x diam., 8-spored, not stained blue 
by iodine. Spores conglobate, 2-celled, constricted, 20-24 x 10-12 /x, dark 
brown when mature and strongly echinulate, rounded at both ends, cells 
sub-equal. Pycnidia similar to thyriothecia but smaller, 100-120 /x diam., 
conidia ovate, brown, 20-25 x 12-15 /x.

I think there can be no doubt that this is the fungus collected by von 
Thihnen, although I have not seen the type specimen. It is the only 
species which agrees with his description, and the host belongs to the same 
genus Capparis. A. celtidicola var. microsj^ora on Maerua differs in the 
size of the spores and asci, and in the form of the hyphopodia. 
Theissen, judging only by the imperfect description ;(Sy 11. F. i, p. 40), 
and not having seen the type, places this species amongst those imperfectly 
known, and remarks on its similarity to A. Cappariclis. From this species 
(or variety, A. celtidicola var. Capparidis), A. sphaerasca differs in the form 
of the hyphopodia, which are taller and not lobed. 
27. Asterina loranthicola Syd. 
Ann. Myc. xii, 3, p. 266. 
Plate XVI, fig. 32. Slides XXV, 9, 16 ; XXVI, 19, 20. 
Amphigenous ; mycelium spreading, composed of hyphae which are 
straight or nearly straight, brown, 4-6 /x thick, and irregularly branched ; 
hyphopodia not at all numerous, alternate, sessile, 1-celled, cylindrical to 
obovate, often uncinate, 9-11 /x long, 5-6 /x broad. Thyriothecia densely 
aggregated, always flattened-hemispherical, 109-160 /x diam., composed of 
straight, radiating hyphae 3*5-5 /x thick, cells rectangular, up to 7 fi long; 
margin fimbriate ; thyriothecial membrane easily separating into its com- 
ponent parts. Asci aparaphysate, ovate to globose, 30-38 X 24-30 /x, 
8-spored. Spores ellipsoid-oblong, 1-septate, brown, rounded at both ends, 
20-24 X 8-11 /X, epispore ciliate, upper loculus often slightly broader.
