210 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
H. rubiginosus is very similar in color throughout to H. 
ferrugineus but differs in being membranaceous, in having 
spores aculeate rather than spinulose, and in having some 
hyphae parallel with substratum and occasionally forming 
rope-like strands. These strands are not mentioned by 
Bresadola in his description, but they are present in prepara- 
tions from the specimen received from him and also in those 
from the few American collections referable to this species. 
Specimens examined: 
Hungary: on leaves of Juniperus and Quercus, Oct., 1888, 
Amet, comm. by G. Bresadola, apparently part of type. 
Canada: Lower St. Lawrence Valley, J. Macoun, 77. 
New York: Greenbush, C. H. Peck, type of Zygodesmus 
rubiginosus (in Coll. N. Y. State); Aleove, C. L. Shear, 
1329; Syracuse, L. M. Underwood, 36, 41 (both in Coll, N. 
Y. State). 
Louisiana: St. Martinville, 4. B. Langlois, ct. 
British Columbia: Sidney, J. Macoun, 80, in part (in Mo. 
Bot. Gard. Herb., 8935). 
3. H. subferrugineus Burt, n. sp. 
Type: in Burt Herb. 
Fructification effused, dry, membranaceous, separable from 
the substratum as a thin membrane, tomentose, drying Sudan- 
brown, with surface often granular in the 
center; structure in section 300—400, thick, 
CH composed of (1) a few dark-colored, nodose- 
EM _ septate hyphae 5-64 in diameter, running 
parallel with the substratum, loosely inter- 
Bee woven or sometimes im rope-like strands 
e и, which give off (2) suberect, bright-colored, 
. S gineus. ` 4 
Hypha, врогехб40. interwoven branches, concolorous with the 
hymenium, bearing the basidia; basidia 4- 
spored; spores concolorous with the hymenium, subglobose, 
echinulate, with spore body 7-9 x 6-8; some color is dissolved 
from the sections when they are treated with KHO solution. 
Fructifications 2-5 em. long, about 2-3 em. broad.
