DECADES OF FUNGI. 205 
elongated; cup hemispherical, concave, margin incurved, Asci cla- 
vate ; sporidia filiform. 
Near allied to P. clavata, Fr., and P. Ciborium, but distinguished by 
. its regular cup, which is not much broader than the stem. It is 
even more minute than P. clavata, which is itself a far less species 
than P. Ciborium.

The disc, in the Darjeeling specimens, has a steel-blue tint, and they 
contract more in drying, in consequence of which the under surface 
appears more rugose and spiculato-verrucose than in British and North 
American specimens. The sporidia in both are. brown and sub- © 
cymbiform, and the inner substance marbled. The Sikkim plant pre- 
sents a distinct variety, but is not, I think, entitled to be aeparsteg as 
species. 
* Hypoxylon tabacinum, Kickx in Bull. de l'Ac. Roy. de Bruxelles, 
vol. viii. n. 8. Sp. involuta, Klotzsch. Hook. fil., No. 95, cum ic. 
Has. On dead wood. Darjeeling, 7,500 feet. June, July. 
The specimens are all young and therefore pale. The surface, when 
fresh, is of a chalky ochre, dotted with the black ostiola. Most of the 
specimens are hollow, and many deeply grooved at the sides as if com- 
posed of two confluent individuals. I have not been able to compe 
the sporidia. 
* Hypoxylon polymorphum, Ehr. 
Has. Sinchul, 8,000 feet. 2 
* Hypoaylon vulgare (Spheria Hypoaylon, Ehr.). 
Has. On old wood. Darjeeling, 7,500 feet. 
. A flagelliform variety, the upper divisions being very long and slen- - 
der. It resembles in habit Montagne's Hypozylon ianthino-velutinum. 
* Hypocrea peltata, Berk. (= Spheria peltata, Jungh.) in Hook. 
Lond. Journ. vol. i. p. 156. t. vii. f. 7.
