Roth. as having "spores smooth." Since most American gatherings have
reticulated spores, and since Schweinitz described a black American
species, his specific name seemed appropriate for all except
smooth-spored forms.

In the meantime two things have happened; Mr. Lister has examined the
specimens remaining in the Strasburg herbarium and finds them with
reticulate spores. The statement quoted from the _Monograph_ evidently
does not apply to _all_ of Rostafinski's material; but under the
circumstances the name _fusca_ may easily take the field, especially
since another discovery makes for the same conclusion. The evidence is
good that _S. maxima_ Schw. was indeed the largest, i. e. perhaps, the
_tallest_ stemonitis he ever saw! probably, as his scanty
herbarium-remnant shows, _S. fenestrata_ Rex!

4. STEMONITIS UVIFERA _n. s._

PLATE XX., Figs. 8, 8 _a_, 8 _b_, 8 _c_.

Sporangia tufted, generally in medium-sized clusters much as in _S.
fusca_. The individual sporangium 7-9 mm. high, dark, slender, brown,
becoming dull black or pallid as the spores are lost, stipitate, the
stipe about one-fourth to one-third the total height, black polished
shining; hypothallus distinct, common to all sporangia, purple-brown,
shining; columella distinct, attaining almost the summit of the
sporangium but inclined to waver a little at last, in other words,
flexuose toward the top, freely branching, the branches rather stout,
anastomosing to support the capillitial net; the meshes larger, several
times the spore-diameter, the spores sooty-brown, distinctly warted or
spinulescent, about 7-8 mu, clustered in groups of four or more.

PLATE X., Figs. 5, 5 _a_, 5 _b_.

Sporangia crowded in colonies of unusual size, 4-8 cm., tall, rigid
18-25 mm., slender, erect, stipitate, black throughout; the columella
prominent, reaching nearly to the apex, abundantly branched, the
branches forming an intricate dark brown capillitium; the net
large-meshed several times the spore-diameter; the spores reticulate,
spinulose, clear vio
