Rev. M. J. Berkeley on some Fungi from St. Domingo. 203 



The specimens seem just intermediate between this and H. 

 rhopahides. Unfortunately I have no authentic sample of Dr. 

 Montagne's plant, and therefore cannot speak positively. H. rho- 

 paloides from Cuba and Surinam is far smaller. This is just the 

 size of what Dr. Montagne figures, but is obtuse and not acute. 



No. 50 is apparently a more slender and dwarf form of the 

 same species. 



65. Hgpoxylon concentricum (Bolton sub Spharia), Salle, 

 no. 48. On dead wood. 



This is as strongly lacquered as Hypoxylon vettiicosum, the 

 essential character of which resides in the loose cellular character 

 of its substance. 



66. Spharia (Circumscripta^) Sallei, n. s. Orbicularis suban- 

 gulata convexa; stromate atropurpureo; ostiolis longis subru- 

 gosis divergentibus basi velatis. Salle, no. 82. On branches of 

 trees. 



Pustules 1-3 lines broad, orbicular, rather angular, immersed 

 in the bark ; stroma purplish black, extending over the base of 

 the divergent, somewhat rugged, elongated, linear, subconical 

 ostiola. 



Unfortunately I have not been able to find any fructification 

 in this fine species. 



67. MeUola amphitricha, Mont. Cuba, p. 326; Salle, no. 73. 

 On leaves of some Smilax. 



The following species of the collection are indeterminable : — 



10. Some Tricholoma near Ag. Columbetta or A. albus. 



2. Some Xaucoria, abundant, but in the absence of notes I 

 cannot say what species. 



11. Some Lepiota, probably a new species allied to A. illinitus. 

 58. A single specimen of an imperfect Marasmius. 



68. Mycelium. 



80. Some fungus unknown. A single specimen without fruc- 

 tification.
