The genus Cladosterigma Pat. T. Petch. 215 
rigid, filiform sterigmata and continuous spores. For these I 
propose a new genus, 7vichosterigma. 
Trichosterigma gen. nov. Stilbaceae. Clavariaeform, covered 
with spherical, subglobose, or ovate basidia, each bearing an 
apical, rigid, filiform sterigma; conidia terminal, solitary, 
hyaline, continuous. 
Trichosterigma clavisporum Petch, n.sp. Mycelium covering 
the insect in a matted glabrous sheet and spreading out in a 
fimbriate margin over the substratum. Clavae arising from the 
mycelium, erect, terete, simple, up to 8mm. high, 0:35 mm. 
diameter below, tapering upwards, brownish white (dry), 
smooth. Basidia crowded, ovate, up to 8 high, 2-3 » diameter, 
rounded or attenuated at the apex. Sterigmata rigid, simple, 
filiform, 5-9 high. Conidia hyaline, continuous, clavate, 
4-8 x I-I-5u. On a caterpillar attached to a living leaf, 
Peradeniya, January 1912. 
Trichosterigma arachnophilum Petch, n.sp. Mycelium covering 
the body of the insect and forming a flattened pulvinate, pale 
yellow, somewhat spongy, tomentose stroma, with a fimbriate 
margin. Clavae arising from the stroma, pallid yellow, cylindric, 
up to 4mm. high, 0-15 mm. diameter below, tapering slightly 
upwards, smooth, simple. Basidia scattered or crowded, globose, 
3 diameter, or subglobose, up to 6 x 5y. Sterigmata simple, 
rigid, about 2m long. Conidia narrow-oval, ends acute, con- 
tinuous, 4-8 x 2u. On a spider attached to a living leaf, 
Hakgala, March 1922; Peradeniya, March 1909; Peradeniya, 
March 1917. This species is the conidial stage of Torrubiella 
flava Petch. The specimen from Peradeniya, March 1909, differs 
in colour, being lilac grey. A similar colour difference occurs in 
Gibellula elegans P. Henn., which is also parasitic on spiders. 
Trichosterigma attenuatum Petch, n.sp. Mycelium scanty, 
brownish, overrunning the host insect. Clavae arising from the 
body or legs of the insect, usually from the joints, or along the 
margins of the wing covers. Clavae pale brown (dry), up to 
6mm. long, 0:2mm. diameter below, tapering upwards to 
0-08 mm. diameter, rigid, slightly inflated at the apex, terete, 
smooth, bristling with hyaline sterigmata when magnified. 
Basidia oval or flask-shaped, 8-I0 x 3p, attenuated into a 
rigid simple sterigma, up to 26m long, 1:5 diameter at the 
base, tapering upwards. Conidia solitary, hyaline, continuous, 
oval or lozenge-shaped, usually acute at each end, 6-7 x 3-5. 
On a Pentatomid on bark, Hakgala, May 1912. The insect in 
the type specimen bears more than forty clavae, but many of 
them have been broken.
