292 Massee—A Monograph of the Geoglosseae. 
The above description is drawn up from specimens in the Kew 
Herbarium, which were collected by Bulliard in the forest of Com- 
piegne, and named by Persoon. 
Distinguished from Leotia lubrica by the unbranched paraphyses, 
not being thickened at the apex, and the much more slender build of 
the ascophore, which is not green. 
Very slightly subtremellose, not greenish yellow. Agreeing admirably 
with the figure in FI. Dan., tab. 654, except that I have not seen the 
stem more than 2 inches long. The name is also excellent, the whole 
substance dry, resembling leather ; tomentose but not veined on the 
under surface (Wahlenb.). 
Gregarious, slender, slightly gelatinous ; not greenish, neither in the 
specimens I have seen, nor in an unedited figure in the library of 
Hornemann. Stem 3-4 in. long, 1-2 lines thick, crooked. Pileus 
\ in. broad, rarely more, subumbonate, margin inflexed, wavy, concave 
and same colour underneath (Fries). 
Leotia aquatica, Libert , in Roumeg. , Fung. Sel. Gall. Exs., n. 639 
(with diagnosis), 1880; Pat ., Tab. Anal. Fung. 32, fig. 75, 1883. 
(PI. XII, Figs. 21-22.) 
Gregarious ; ascigerous portion convex at first, then plane or some- 
what depressed, margin slightly incurved, rufous, glabrous, 3-6 mm. 
broad, rather fleshy ; stem slender, 1-2 cm. long, often flexuous, white, 
cylindrical, glabrous, base tomentose. Ascus clavate, apex slightly 
narrowed, not blue with iodine, about 70 x 8 ; spores 8, 2-seriate 
above, becoming 1 -seriate below, elliptical, ends narrowed, sometimes 
slightly curved, 11-14x4 /*; paraphyses slender, slightly clavate and 
brownish at the tips, more or less agglutinated together. 
Syn. — Cudonia aquatica , Quelet, Enchirid. 267, 1886. 
Cudoniella aquatica , Sacc., Syll. viii, n. 135, 1889; Rehm., Kr.-FL, 
n. 5884, 1896. 
Hab. — On submerged wood and branches. 
Distr . — Germany, France. 
Schroter (Krypt.-Flora von Schlesien, iii, pt. ii, p. 21) says the asci- 
gerous portion is ‘white when fresh, brownish when dry'; this state- 
ment is repeated by Rehm. Both these authors also give the same 
spore-measurements (7-9 X 2-3 /t)> which are less than those found 
on examining Madame Libert’s specimens.
