stipes of Agaricus. It originally was a bag enveloping 
the whole plant, and was left at the foot of the stipes 
when the plant elongated and burst through it. 
4. The Velnm^ or Veil^ is a horizontal membrane, connecting 
the margin of the pileus with the stipes : when it is 
adnate with the surface of the pileus, it is a velum 
universale ; when it extends only from the margin of the 
pileus to the stipes, it is a velum partiale. 
5. The Annulus, is that part of the veil which remains next 
the stipes, which it surrounds like a loose collar. 
6. Cortina, is a name given to a portion of the velum which 
adheres to the margin of the pileus in fragments. 
7. The Hymenium, is the part in which the sporules imme- 
diately lie; in Agaricus, it consists of parallel plates, 
called lamellce, or gills. These are adnate with the stipes, 
when the end next it coheres with it: when they are 
adnate, and at the same time do not terminate abruptly 
at the stipes, but are carried down it more or less, they 
are decurrent; if they do not adhere to the stipes, they 
are said to be free. 
8. Stroma, is a fleshy body to which flocci are attached; as 
in Isaria and Cephalotrichum. 
9. Flocci, are woolly filaments found mixed with sporules in 
the inside of many Gastromyci. The same name is also 
applied to the external filaments of Byssaceae. 
10. Orhiculus, is a round flat hymenium contained within the 
peridium of some fungi ; as Nidularia. W. 
11. Nucleus, is the central part of a perithecium. 
12. Sporangium, is the external case of Lycoperdon and its 
allies. 
13. Sporangiola, are cases containing sporidia. 
14. Perithecium, is a term used to express the part which 
contains the reproductive organs of Sphaeria and its co- 
ordinates. 
15. Peridium, is also a kind of covering of sporidia; peridio- 
lum is its diminutive. 
16. Ostiolum, is the orifice of the perithecium of Sphaeria. 
17. Spherula, is a globose peridium, with a central opening
