384 Rev. M. J. Berkeley on Fungi. 



Jamaica. Herb. Mus. Brit. On rotten wood. 



Plant 1^ inch high ; mycelium white, branched, fibrillose, 

 penetrating into the wood ; stem compressed, 1 \ line thick, 

 springing from a broader base, divided above into four prin- 

 cipal, rather flexuous, slender cylindrical branches connected 

 at the base, and forked once or twice only ; tips very acute. 

 The whole plant is of a pallid ochraceous hue. 



This species is evidently allied to Clavaria crispula and 

 byssiseda. It agrees more with our common forms of Cla- 

 varia than those which are peculiar to the Tropics.

44. Exidia rufa, n. s. Cupularis sublateralis intus nigra ; 

 extus setis brevibus fasciculatis rufis vestita. 



Herb. Mus. Brit. Ceylon, Konig. 



Two or three inches or more across, cup-shaped, generally 

 attached laterally ; very hard and rigid when dry ; slightly pli- 

 cate at the base, clothed with short, fasciculate, hispid, bright 

 sienna-brown bristles. Hymenium smooth, not much wrin- 

 kled, dark brown, inclining to black. Very distinct from every 

 species I have seen in its bright red-brown bristles. The 

 nearest species is Exidia polytricha, Mont.

 Jamaica, Mr. Poore. Herb. Mus. Brit. 



This is perhaps Pes. nigra, Swartz, which is certainly an 

 Exidia. 



46. Sphaeria thyrsus, n. s. Suberosa, simplex, clavula ob- 

 ovata acuminata pallida, peritheciis sursum spectantibus mag- 

 nis, ostiolis subelongatis obtusis nigris ; stipite elongato cy- 

 lindrico deorsum longissime radicato. " Clathrus acuminatus" 

 Roxb. 



In the Botanic Garden, Calcutta. Herb. Mus. Brit. 



Whole plant nearly six inches high, rooting deeply into 

 the soil ; root flexuous, attenuated downwards ; stem cylindri- 

 cal, nearly equal, black, slightly wrinkled, white within, sur- 

 mounted by the pale fawn-coloured, acuminate, obovate head, 

 which is rough from the protrusion of the black ostiola, which 

 all point upwards, so as to give it the appearance of a little 

 fir-cone. Perithecia obovate, with a short neck. Asci linear, 

 obtuse, containing eight subcymbiform dark brown sporidia, 

 which are furnished on one side with a gelatinous coat pro- 

 jecting beyond the apices. 



This species, of which I understand from Dr. Brown much 

 larger specimens occur, is allied to Sph. pedunculata, Dicks.
