Tubifera stipitata (Berk. & Ray.) Macbr. 
1868. Licea stipitata Berk, and Rav., Jour. Linn Soc, X p 
350. 
1875. Tubulim stipitata (Berk. & Rav.) Rost. 
Macbride: Sporangia crowded in a globose or more or less 
hemispheric, expanded head, borne upon a spongy, stem-like, sili¬ 
cate hypothallus, their apices rounded, their walls very thin, 
evanescent ; spores in mass umber-brown, small, about 5y, the 
epispore reticulate as in T. ferruginosa. This species differs 
from T. ferruginosa chiefly in the cushion-like receptacle on 
which the crowded sporangia are borne, and in the smaller 
spores.” 
Saccardo adopts the name Tubulina stipitate (Berk. & Rav.) 
Rost. He differs from Macbride in calling the spores delicately 
warted. 
Lister finds the spores to be minutely reticulated over the 
greater part of the surface, the remaining part smooth or marked 
with ridges, and 3 to 5/m in diameter. 
Massee adopts the name Tubulina stipitata Rost. He describes 
the spores as having about three-fourths of the surface covered 
wdth a regular small network, the remainder with much larger 
meshes. 
I find the distinctive points of this species to be the stem-like 
hypothallus, and the small size of the spores. The spores are 
finely reticulated over the greater part of the surface, the re¬ 
mainder having a very irregular network of rather coarse ridges. 
The one group of specimens which I have was found in Vilas 
woods, July 16, 1904, growing on much decayed oak. 
Cribraria aurantiaca Schrad. 
1797. Cribraria aurantiaca Schrader, Nov. Gen. PI., p. 5. 
Saccardo: “Sporangia gregarious, spherical, more or less 
cernuous, stipitate, tawny to dark tawmy; stipe attenuate above, 
dusky; calyculus well developed, hemispherical, the margin 
armed w T ith short acute teeth; nodules commonly much branched, 
the apices prolonged so as to at length join with one another;
