94 THE ATLANTIC. [CHAP. f. 
notes of its height; a fragment of a frond (between pieces of card) and 
the base of a stipes should be tied to the specimen of the stem; also a 
note as to whether the adventitious roots were living or dead. 
The number of fronds should be counted, their dimensions taken, 
and the basal scales carefully preserved. 
Note if tree-ferns are ever attacked by insects or fungi, and whether 
they form the food of any class of animals. 
13. Mosses, etc—Many mosses are aquatic. In the case of diccious 
species of mosses, plants of both sexes should be, when possible, secured. 
14. Aquatic species of Ricciacee should be looked for. Minute 
Jungermanniacee are found on the foliage of other plants. 
15, Podostemacee are found in rocky running streams in hot coun- 
tries, ‘They have a remarkable superficial resemblance to Hepatice.- 
Except at the flowering season, they are altogether submerged. Speci- 
mens should be preserved in spirit as well as dried. 
16. Fungi.—Take notes of all fleshy fungi, especially as regards col- 
or; the spores should be allowed to fall on paper, and the color of these 
noted also. The fleshy species may sometimes be advantageously im- 
mersed in spirit before preparing for the herbarium. 
17. Examine the fungi which grow on ants’ nests, taking care to get 
perfect as well as imperfect states, and to secure, if possible, specimens 
which have not burst their volva. 
18. Look out for luminous species, and ascertain whether they are 
luminous in themselves, or whether the luminosity depends on decom- 
position. 
19. Secure specimens of all esculent or medicinal fungi which are 
sold in bazaars, noting, if possible, the vernacular name. 
20. Note any species of fleshy fungi which arise like the Pietra 
Fungaa from a mass of earth impregnated with mycelium, or from a 
globose resting-mass. 
21. Attend especially to any fungi which attack crops, whether cereal 
or otherwise; and particularly gather specimens of vine -mildew and 
potato-mildew, should they be met with. Even common wheat-mildew, 
smut, etc., should be preserved. 
22. In every case note date of collection, soil, and other circum- 
stances relative to particular specimens. 
23. Look after those fungi which attack the larvee of insects. 
24. In the case of the Myzogastres, sketches should be made on the 
spot of their general form, with details of microscopic appearance. It
