the bristles of P. scutellata and many other species, consist of a 

 single row of cells, but are composed of a great many connate 

 articulated threads. P. tricholoma, Mont., is smaller, and has 

 the external surface costate. 



59. Peziza Hindsii, Berk, in Hook. Lond. Journ. vol. i. p. 456 ; 

 Salle, no. 36. On dead wood. 



This species closely resembles P. sulcipes, Berk., of which I 

 have a specimen from Dr. Montagne marked P. tricholoma, but 

 which does not at all accord with his figure or description. 

 There are no anostomosing raised lines on the surface of the cup, 

 and the bristles are very much shorter. P. Afzelii, Fr. Nov. 

 Symb. p. 105 ; Afz. Ic. f. 50, is a smaller species of the same 

 group. 



60. Hypoxylon vulgare (Sphceria Hypoxylon, Ehr.), Salle, 

 no. 49. On dead wood. Abundant. 



61. Hypoxylon comosum, Mont. Ann. d. Sc. Nat. 1840; Salle, 

 noi51. On dead sticks. A single specimen. 



62. Hypoxylon obtusissimum, n. s. Capitulo brevi late ellip- 

 tico-clavato obtusissimo stipite brevissimo, cuticula fragili tenui, 

 ostiolis minutissimis. Salle, no. 47. 



Head 1^ inch long, nearly 1 inch thick, elliptico-clavate, very 

 obtuse, covered with a thin brittle purple-brown coat, darker be- 

 low. Surface smooth, with the exception of the extremely mi- 

 nute ostiola, which are scarcely visible to the naked eye. Stem 

 extremely short. 



This species has the habit of H. allantoideum, but differs in its 

 very thin brittle cuticle and the much smaller ostiola. H. zey- 

 lanicum is far more rigid, besides being rather different in habit. 



63. Hypoxylon Domingense, n. s. Maxima cyliudrico-clavse- 

 formis deorsum furcata rigida laccata fusco-purpurea ostiolis pro- 

 minulis asperula sursum involuta. Salle, no. 46. On dead wood. 



Heads cylindrico-clavate, 6 inches high, f of an inch thick, 

 forked below, hard, rigid, covered with a dull purple-brown, lac- 

 cate, minutely cracked crust, involute above, slightly rough with 

 the ostiola, which are visible to the naked eye. Stern distinct, 

 about 1 inch high. 



This magnificent species resembles closely H. allantoideum, 

 but is more cylindrical, longer, minutely cracked and involute 

 above. It resembles also Hyp. fistulosum, Lev., which has how- 

 ever more prominent ostiola and more regular obtuse heads. I 

 do not know any other speeies with which it requires comparison. 

 Its habit in its own section resembles somewhat that of well- 

 developed specimens of //. corniformis, but stouter and more 

 shortly stipitate. 



64. Hypoxylon grammicum, Mont. Ann. d. Sc. Nat. Apr. 1840; 

 Salle, no. 45. On dead brauches.
