Vin. FUNGI. 
[. Agaricus . 
73. Nectkta. Stroma 0, or bearing the naked coloured perithecia on its surface. 
74. SpHiERiA. Stroma 0. Perithecia black, pierced at the apex, superficial or erum- 
pent. 
75. Capnodium. Mycelium of black, branched, jointed filaments. Perithecia elongate, 
of confluent filaments, with often free tips. 
76. Miceopeltis. Perithecium free, carbonaceous, flattened, dimidiate, scutate. Asci 
clavate. Sporidia septate. 
76. Pkmphidium. Perithecia spurious, convex, black, formed of the epidermis. Nucleus 
gelatinous. Asci perfect. Sporidia elongate. 
Tribe XXIII. Perisporiacei. Perithecia free, subglobose, always closed , except when 
decaying, membranous or carbonaceous. Nucleus never diffluent. Asci springing from 
the base. 
77. Eeysiphe. Mycelium cobwebby. Perithecia soft; appendages floccose, simple or 
branched. 
78. Ch/etomium. Perithecium thin, brittle. Asci linear, with dark mostly lemon-shaped 
sporidia. 
79. Meliola. Perithecia carbonaceous, from a strigose mycelium. Asci broad. 
Suborder VI. Physomycetes. — Filaments free or slightly matted, hear- 
ing vesicles which contain indefinite sporidia. 
To this tribe belong the true moulds ( Mucor , etc.) of which species must occur abundantly 
in New Zealand, though they have never been collected. Antennaria is an anomalous 
member of it. 
Tribe XXIV. Antennariei. Filaments black, matted, often moniliform. 
80. Antennaria. Filaments articulated. Walls of sporangia mostly cellular. Spores 
chained together, immersed in gelatinous pulp. 
1. AGARICUS, L. 
Fleshy putrescent Fungi. Hymenium inferior, spread over the surface of 
membranous persistent gills, formed of closely-packed cells. Gills radiating 
from the centre of a pileus, with shorter ones between, formed of 2 separate 
membranes, their edges acute. Substance of the gills internally filamentous, 
continuous with that of the pileus. 
An immense ubiquitous genus, containing upwards of 1000 species, including the Mush- 
room, Toadstool, etc. The species are very variable and difficult to determine from dried 
specimens ; they should be drawn, coloured, and described when gathered, dried by slicing, 
and the colour of the spores noted. 
KEY TO THE SUBGENERA. 
Series I. Iieucospori. Spores white. 
Subgenus I. Amanita. Pileus centrical. Young plant enclosed in a membranous free 
volva, through which the pileus pushes. Fully-formed plant with a veil extending from the 
circumference of the pileus to near the top of the stem. Gills not decurrent on the stem. 
Subgenus II. Lepiota. Pileus centrical. Veil enclosing the young plant, connate with 
the cuticle of the pileus; when burst, leaving a ring on the middle of the stem. Gills not 
decurrent on the stem. 
Subgenus III. Teicholoma. Pileus centrical. Veil obsolete or floccose, and adherent 
to the circumference of the pileus. Stem fleshy. Gills emarginate behind, not decurrent on 
the stem.
