SOUTH AFRICAN FUNGI. 
Xylaria stilboidea, Kalch. £& Cke. 
Parva, stipitata. Capitulum subglobosum, atrum (1-2 mm. diam.) 
ostiolis exsertis asperatum. Stipite cylindrico, fusco (1-1^ mm. 
long) gracili. Stromate albo. Peritbeciis atris, immersis. 
Ascis cylindraceis. Sporidiis uniseriatis, ellipticis, atro-fuscis 
(•014-‘015 X ’005 mm.). 
On wood. No. 42. 
A very minute species, with the habit and appearance of a species 
of Stilhum. 
Hypoxylon placenta, Kalch. 
Corlicola, applanata, atra, erumpens. Stromate discoideo, 
margine tenui, sterili, centro ostiolis punctiformibus punctato ; 
ascis cylindraceis ; sporidiis uniseriatis, ellipticis, atro-fuscis ('012 
X '006 mm.). 
On branches. No. 1304. 
Closely allied to H. exutans, Cke., of which it may possibly be 
only a variety. 
Diatrype caminata, Kalch. de Cke. 
Erumpens, suborbicularis, convexa, nigrescens ; ostiolis exsertis, 
cylindricis, obtusis, truncatis. Ascis clavatis. Sporidiis linearibus, 
curvulis, hyalinis (-012 x *003 mm.).

The specimens were old, and in bad condition. The exserted 
ostiola are abruptly truncate. Probably also the specimen (No. 23), 
provisionally named Diatrype congesta^ is only the same species 
with the ostiola broken off, and all the asci dissolved.

On branches. No. 1344a. 
The asci and sporidia profuse and very minute.

mollibus, sparsis, tectis, papillatis, demum depressis, e subiculo 
strigoso atro-fusco emergentibus. Ascis cylindrico- clavatis. Spo-
