55. Ceadosforium. Filaments flexible, branched, jointed. Spores short and septate. 
Tribe XVII. Mucedines. Filaments not coated with a membrane , distinct , white or 
coloured. Spores mostly simple. 
The moulds which belong to this tribe have never been collected in New Zealand. 
Teibe XVIII. Sepedoniei. Spores collected on a fioccose mycelium , very abundant' 
Fertile filaments scarcely distinct from the mycelium. 
56. Sepedonium. Spores large, simple, globose or appeudiculate. 
Teibe XIX. Trichodermacei. Spores enclosed within or covered by a fioccose myce- 
lium, which at length bursts. 
57. Pilacre. Stipes solid. Heads of flexuose, branched threads. Spores forming a 
dusty mass. 
Suborder V. Ascomycetes. — Fruit consisting of asci, containing spori- 
dia, and springing from a naked or enclosed nucleus or bymenium, which 
is often spread over a receptacle. 
Morells and Truffles belong to this tribe, and are doubtless to be found in New Zealand, 
as is Cyttaria, a curious genus found on Beech-trees in Tasmania and Fuegia, but not 
hitherto in these islands. 
Teibe XX. Elvellacei. Substance soft, fleshy or tvaxy. Iiymenium more or less 
exposed. 
58. Leotia. Receptacle pileate, stipitate, covered everywhere with the smooth rather 
viscid hymeuium. 
59. Geoglossum. Receptacle clavate. Hymenium surrounding the club. 
60. Peziza. Receptacle cup-sbaped, its disk naked. Asci fixed. 
61. Patellaria. Receptacle patellseform, margined. Hymenium dusty from the spores 
breaking up. 
62. Cenangium. Receptacle coriaceous, at first closed, then open and margined, covered 
with a thick cuticle. 
Teibe XXI. Phacidiacei. Perithecium coriaceous or carbonaceous ; outer coat or pe- 
rithecium bursting and exposing the disk, which is surrounded by an obtuse or inflected 
margin. 
63. Hysterium. Perithecium labiate ; border entire ; orifice narrow. Asci elongate. 
64. Ailogeaphium. Perithecium branched ; orifice narrow. Asci subglobose. 
65. Asteeina. Perithecium suborbicular, in a byssoid mycelium, splitting irregularly. 
Asci short. 
66. Excipula. Perithecium carbonaceous, spherical ; mouth orbicular; nucleus gela- 
tinous. 
Tribe XXII. Sphaeriacei. Perithecium carbonaceous or membranous, pierced at the 
apex. Hymenium diffluent. Asci usually springing from the walls. 
67- Coediceps. Stroma vertical, erect, coriaceous or fleshy. Receptacle distinct. Spo- 
ridia submoniliform. 
68. Hypocrea. Stroma horizontal. Perithecia tender, hyaline or coloured. 
69. Xylaeia. Stroma vertical, fleshy or corky, with a black or rufous bark. Recep- 
tacle stipitate. 
70. Hypoxylon. Stroma brittle or corky, flat or convex, at first clothed with a fioccose 
veil, then with a black crust. Perithecia vertical or divergent. 
71. Diatrype. Stroma confluent with the matrix. Perithecia sunk, elongated into a 
distinct neck. 
72. Dothidea. Stroma with globose cavities containing nuclei, which have a decided 
neck and papillEeform aperture. Perithecium 0.
