296 Massee. — A Monograph of the Geoglosseae . 
Fries a Spathularia differing from S.flavida in having slightly differ- 
ent spores, measuring 48x3/*, whereas his measurements for S.flavida 
are 72 x 2 n (Symb. Myc. 332). Berkeley, on the "Other hand, con- 
sidered the New England fungus communicated by Sprague to 
represent S. crispata of Fries, but, observing that the spores were 
elliptical, placed it in the genus Mitrula , without, however, giving 
a diagnosis, but simply stating, c Sporidia elliptic, uniseriate/ As the 
fungus under consideration is neither a Spathularia nor a Mitrula , 
neither does it accord with any hitherto defined genus, it is named 
after its discoverer, one of the pioneers of N. American botany 
(Massee, Journ. Bot. 1 . c.). 
Hemiglossum, Pat. 
Ascigerous portion gelatinous, coriaceous, simple or branched, tongue- 
shaped or convolute, stipitate ; hymenium unilateral; asci elongated, 
opening by a pore ; spores 8, small, ovoid or fusoid, hyaline. 
Hemiglossum, Patouillard, Rev. Myc. 1890, 135; Sacc., Syl. 
Suppl. x, p. 2, 1892. 
Distinguished at once from all other genera by the more or less 
incised vertical ascigerous portion having the hymenium developed on 
one surface only, the other surface remaining sterile. This differentia- 
tion of surfaces is also met with in Leotia and Vibrissea, but in both 
these genera the ascigerous portion is pileate and horizontal, the upper 
surface being fertile, the under surface sterile. Hemiglossum is 
analogous in the arrangement of its hymenium with Skepperia and 
Lachnocladium , genera belonging to the Basidiomycetes. 
Distr. — Only one species known, China. 
Hemiglossum Yunnanense, Pat., Rev. Myc. 135, pi. cvii bis , fig. 2, 
1890; Sacc., Syll. Suppl. x, n. 4468, 1892. (PI. XIII, Figs. 83, 84.) 
Ascigerous portion simple or branched, more or less incised or 
lobed, margin revolute below or all round, thin, about 1 mm. thick, 
10-15 mm. long, 4-8 mm. broad, smooth, tawny; concave sterile 
face paler, furfuraceous owing to the presence of tufts of ovoid, brown 
cells ; stem rigid, slender, straight or flexuous, reddish brown, 1-2 cm. 
long, 2-4 mm. thick. Asci stipitate, elongated, apex obtuse, becoming 
tinged blue round the pore with iodine, 55-60 x 4 /* j spores 8, 
1 -seriate, hyaline, continuous, fusoid, ends rather acute, 2-guttulate, 
6-7 X 1*5-2 n ; paraphyses linear, simple, hyaline.
