278 DECADES OF FUNGI 



Fungi, for tteir habitat is quite against such a supposition. The pro^ 

 bability is that they are anamorphoses of certain Lichens : the truth 

 can probably be ascertained on the spot only where they grow, 



* Ch/athus limlatu8, Tul. Ann. d. Sc. 1844. Spruce, n. 148. 

 Hab. On the half-putrid rhizoma of Alpinia aromatica. Panure, 



February, 1853. 



615. Scleroderma stellatum, n. s. ; peridio coriaceo demum stellato- 

 refleko umbrino stellato-verrucoso ; sporis umbriuo-argillaceis. 



Hab. On the ground- Panure. 



About 1 inch across, umber-brown ; peridium coriaceous, at length 

 splitting ia a stellate manner, rough with minute, stellate warts. Spores 

 argillaceous, tinged with umber, globose, verrucose, g-gVo ^^ ^^ ^^^^ ^^ 

 diameter. 



I know of no Scleroderma which at all accords with the present, of 

 which unfortunately only a single specimen was procured. 



* AscJiersonia oxyspora^ B., Hook. Joum, vol. vi. p. 205. 

 Hab. On dead leaves. Saa Carlos. 



Flesh-coloured when fresh. Externally resembling the Khasia spe- 

 cimens. The hymenium is more convolute within, and the spores, in- 

 stead of Y^^> ^^^ 2 s'o Q *>f ^^ ifich long, differences which are not 

 enough to constitute a distinct species. 



.616. Mycogone sphcerospora^ n. s.; strato candido; sporis globosis 

 simplicibus fortiter echinatis. Spruce, n. 96. 



Hab. On the gills of some Agaric, in woods near the Eiver Uaupes. 

 March, 1853. 



Stratum white. Spores globose, y^oo of an inch in diameter, sim- 

 ple, without any trace of a second articulation, rough with strong, 

 rather obtuse spines. 



The Agaric on which this mould is developed is said to be pale, with 

 purple spores, but not a trace of the organs of fructification remain, 

 and the species is altogether indeterminable. The spores of the para- 

 site are a beautiful object under the microscope. 



617. Co^rdyceps hkephala^ n. s. ; stipite elongate gracili brunneo 

 apicc furcato pulverulento ; clavis ellipticis pulverulentis ; sporidiis fill- 

 forimbus. 



Hab. Panure. 



Stem 2 inches high, very slender, curved at the base, brown, forked 

 above, and pulverulent ; heads elliptic, pulverulent, even. Asci linear* 

 Sporidia very slender, linear.
