not show in the first mount of glycerine and alcohol, while cysts 
that are pendent can easily be seen; pendent cysts are beneath the 
entire head, while appressed or pulvinate cysts are peripheral; a 
third type of cysts is seen in thoose heads with many spheroid 
cysts beneath the surface, but not pendent. Ravenelia microcystis 
is an example of this class. Many of the appressed type of cysts 
will appear as if pendent when mounted in water or in a lactic 
acid solution, for they then swell up and hang down around the 
stipe like truly pendent cysts. 
Two new species are here described, one from Florida and 
the other from Jamaica. Also emendations and remarks on sev¬ 
eral Mexican and Texan species heretofore described. 
Ravenelia piscidiae Long n. sp. — Sori sub-epidermal, 
II sori mainly hypophyllous, III sori usually epiphyllous. II 
sori small, punctiform, on pallid spots that show markedly on the 
upper surface of the leaves; II sori cinnamon brown, scattered or 
in irregular groups. II spores sub-globose, somewhat angular, 
strongly and closely verrucose, germ pores scattered, about 8, 
fulvous, walls unifom, 17-20x20-23 /x, usual size, 20x20 /x. 
Paraphyses sparingly present, hyphoid to sub-clavate, often curved 
like a golf club, fulvous, 10 x 30-35 /x, bases semi-hyaline and 
collapsed. Ill sori on different leaves, epiphyllous, small, orbic¬ 
ular, black-brown, firm, well scattered over entire surface of leaf. 
III heads chestnut brown, smooth pulvinate, 65-80/x, 4-5 spores in 
cross section, many heads only ten-spored, 6 peripheral and 4 
central ones; paraphyses sparingly present in III sori, cysts 
hyaline, flat, appressed, peripheral, coherent into stipe, swelling 
and bursting in water; pedicel short, deciduous, hyaline.

This species is close to R. uleana, but differs in its pedicel 
being short and its cysts being flat and in all its gross characters. 
Ravenelia arthuri Long n. sp. — Sori sub-epidermal, 
epiphyllous; II sori not present. II spores intermixed with III 
spores. II spores fulvous, walls thick, uniform, spinulose, oval 
to globose, germ pores scattered, more than 6, 20 x 20-26 jx, par¬ 
aphyses not present. Ill sori linear to elliptical, small, surrounded 
by the very prominent ruptured epidermis, black brown. Ill heads 
pulvinate,chestnut brown, smooth, 75-100x40-45 jx thick, 4-8 
spores across, heads often irregular, cysts very many, pendent, 
beneath entire head, globose, hyaline, with a brown, finger-like 
projection from base into center of cyst, swelling and finally burst¬ 
ing in water; pedicel short, compound, hyaline, deciduous, cysts 
often separating from heads.
