SOME EXTRA-EUROPEAN FUNGI. 
15 
Amongst some fragments of petioles of Astrocatyum , from 
Brazil, specimens of a superficial Sphceria were found, of which 
the following is a description : — 
Sphaeria (Denudatae) astrocaryi. Cooke. 
Subgregaria, vel sparsa, atra ; peritheciis superficialibus, rugosis, 
vix papillatis ; ascis clavatis ; sporidiis fusiformibus rectis, vel 
leniter curvulis, multiseptatis (8-10) hyalinis, *06-’ 07 + *007 mm. 
On petioles of Astrocaryum , Brazil. 
At length we have succeeded in obtaining, through Mr. G. 
Western, of Madras, specimens of one of the kinds of smut which 
affects rice in India. It, is of a dingy olive colour, pulverulent, and 
surrounds the grain, destroying the whole substance, except a small 
portion in the centre. See ‘‘Fungi, their Nature,” &c., p. 224. 
Ustilago virens. Cooke. 
Pulverulentum, effusum, olivaceo- virens ; sporis globosis, olivaceo- 
fuscis, episporio granulosis, *005 mm. 
On grains of rice ( Oryza sativa .) Tinnevelly, India. 
Penicillium tenellum. Cke. 
Effusum, pallide fumosum. Hvphis gracilibus, simplicibus vel 
furcatis, brevibus, septatis, diaphanis ; sporis globosis, minimis, 
hyalinis, *003 mm. diam. 
On fading leaves of Symplocos. Bengal, India. 
The effused patches are as much as an inch in diameter, but very 
thin, and but little darker than the leaf. The threads are very 
delicate and short, not exceeding one-tenth of a millimetre.
