6 DECADES OF FUNGI. 



taining two globose nuclei, which themselves also apparently 

 contain a nucleus. 



Allied to P. subhirsuta, but differing essentially in the 

 form of the sporidia. In that species, as published by 

 Desmazieres, n. 462, I find them oblong- elliptic, with the 

 apices quite obtuse. [I know of no instance of fusiform 

 spores in Pezisa, except in a variety of P. leucoloma, figured 

 by Corda, Fasc. 2, fig. 135. 



109. Leotia elegans, n. sp.; stipite elongato gracili sursum 

 subattenuato ; capitulo brevi clavseformi stipite vix cras- 

 siore. 



United States, North America, Mr. Greene. 



Stem 2 4 inches high, scarcely half a line thick, smooth, 

 slightly attenuated upwards. Head 1-2 lines long, a little 

 thicker than the stem, clavseform, sometimes bifid. The 

 whole plant when dry is of dull orange-brown. This is a 

 very distinct species, allied to Leotia uliginosa, with which 

 it cannot be confounded. If I have seen correctly, the asci 

 are lanceolate, and the sporidia oblong. It is not described 

 by Schweinitz. 



110. Spheeria (Lignosse) enteroxantha, n. sp.; insequalis 

 suborbicularis rugosa nigra intus pulverulenta aurea ; peri- 

 theeiis oblongis ; ostiolis prominulis punctiformibus. 



On dead sticks. British Guiana, Sir R. Schomburgk. 



About 1 line broad, irregular, subglobose, bursting through 

 the bark, rugged ; sometimes confluent, black ; perithecia 

 oblong with a short neck, more or less powdered with 

 yellow ; stroma golden yellow in the centre, as is also the 

 surface of the wood beneath the bark. Ostiola prominent, 

 punctiform. Asci narrow, clavate. Sporidia very minute, 

 curved. 



Closely allied to S. flavovirens, but distinguished by the 

 golden yellow of the centre of the stroma. The sporidia 

 agree in form.
