48. IIytocrea papyracea. Ell. & Hoi. n. s. Under side of an 
old log. Decorab, Iowa (Ilolway). 
Stroma membranaceous, thin, separable, 2—3 cm. across, white with 
a yellow, substerile margin ; perithecia superficial, fawn-colored, small 
(150 /^-), thickly scattered on the stroma; asci slender, about 75 x 3 /^-, 
(spore-bearing part about 60 /j), without paraphyses; sporidia fusoid, 
hyaline, 1-septate, 8—10 x 2i—3 /^-, readily separating at the septum. The 
yellow margin may be only accidental. This differs from IL corticioides, 
11. & Br., in its larger sporidia and different color. 
49. Hypocrea digitata. Ell. & Holway. Journ. Mycol. I, p. 42. 
On a dead limb. White mountains, (N. H. Miss Minns. 
Stroma carnose, yellowish, digitate, radiating from a central point 
and dividing into numerous (2millim. in diam.) semicylindrical, finger- 
like lobes, closely oppressed to and surrounding the matrix and extending 
longitudinally for about 5 cm. The rounded ends and the sides of the 
lobes are sterile, the perithecia being found only on the upper or outer 
surface ; perithecia immersed, their position being indicated only by the 
prominent but minute black ostiola ; asci cylindrical, 80—90 long; 
sporidia 1-seriate, ends mostly overlapping, hyaline, 1-septate, oblong or 
narrow-elliptical, often subinequilateral, 20—20 x 6—8 /^. The stroma is 
like the fingers of a hand clasping the limb. The sporidia are those of a 
Hypomyces, to which, perhaps, this should be referred, though it is not 
parasitic on any other fungus, unless the finger-like lobes are an abortive 
growth of some hymenomycete, which is not impossible. 
50. Hypocrea citrinella, Ell. Bull. Torr. Bot. Club, VI, p. 108. 
Stromata scattered or subconfiuent, minute (1—2 millim.), thin-pul 
vinate, bright lemon-color, atro-punctate from the minute ostiola; asci 
slender, 100—120 x 5—6 y ; sporidia fusoid, hyaline, 1-septate, 1-seriate, 
12-14 X 3—3i y. On dead twigs and limbs of Vaccinium corymbosum not 
yet fallen and not much decayed. In the original description, the true 
character of the sporidia was overlooked, the specimens first found being 
rather old and the cells of the si)oridia separated. 
E. Stroma pulvinate. Sporidia fusoid, 3-septate, bi'own or yellowish. 
51. Hypocrea Ravenelii, B. Grev. IV, p. 14. Rav. Car. V, No. 51. 
Bulvinata, rugosa, rubra ; ascis clavatis; sporidiis biseriatis, fusi- 
formibus, demum triseptatis, .0015—.0016 inch long. On Ostipa Virgin- 
ica, Acer ruhrum. Car. Inf., 1575.” This description, copied from Gre- 
villea, applies well to the specimen in Rav. Car., except the color which, 
in RavenePs specimen, is cinereous or argillaceous. The young speci¬ 
mens, however, are a dull brick red, but never bright red. There is some 
contusion as regards this species and H. scutellceformis, B. & Rav. As 
already noted, the two are said by Cooke to be the same (Grev. XII., 78), 
but the specimens of the two species in Rav. Car. are quite distinct. 
H. Ravenelii, Berk., as represented in Rav. Car. A’', 51, is as follows : 
Stroma erumpent, tubercidiform-convex. clay color, becoming darker.
