Growing on hard wood of Ulmus; Preston, O. The peri- 
thecia about 0.2 mm. in diameter, nearly always connate, 5-10 
together into a small tubercle and the wood often blackened be¬ 
neath them. The specific name is given because the plant an¬ 
swers remarkably well to the Sphaeria botryosa described by 
Fries, S. M. Ill, 342. The genus Bertiella should stand next 
to Ziznoella or else be incorporated with it. 
Enchnosphaeria hispida Morgan n. sp.—Perithecia super¬ 
ficial, gregarious, ovoid, the wall thick and carbonaceous, clothed 
with long, black, straight bristles. Asci clavate-cylindric, 8-spor- 
ous, paraphysate, 110-120 x 10-12 mic.; spores clavate-oblong, 
obtuse at both ends, hyaline, 0-3-septate, 15-20X 5-8 mic. 
Growing inside the bark of Acer; Preston, O., 1897. Per¬ 
ithecia 0.3-0.4 mm. in diameter, the thick straight bristles o. 1-0.2 
mm. in length. 
Acanthostigma dispar Morgan n. sp.— Perithecia super¬ 
ficial, ovoid, black, papillate, the surface with minute scattered 
bristles or nearly glabrous, the wall composed mostly of large 
globose membrainaceous cells. Asci lanceolate, curved, 8-spor- 
ous, the spores overlapping 2-3-seriate, the paraphyses scanty, the 
stalk very short, 160-180 x 9-12 mic.; spores linear-fusiform, 
curved, hyaline, 7-11-septate, 45-60 x 4 mic. 
Growing on rotten wood; Preston, O., 1900. Perithecia 
gregarious, closely crowded or scattered 0.3-0.4 mm. in diameter. 
The young perithecia are distinctly bristly but the short bristles 
nearly disappear at-maturity. The globular cells of the wall ex¬ 
pand when moistened and are 20-25 mic. in diameter; this feature 
suggests the genus Winterina and indeed if Berlese’s definition 
of the genus Winterella is to be accepted the species is so refer¬ 
able ; the wall of the perithecium is tuberculigerous at least when 
moist. The species is closely related to Acanthostigma scopula 
and A. minutum; this is plainly shown by Berlese’s “Clavis ana- 
lytica”, division D. To these must be added A. scleranthoides 
and A. chusqueae in the Sylloge XIV. 
Hypoxylon regale Morgan n. sp.— Stroma superficial, 
effused in small irregular spots or patches, composed entirely 
of confluent perithecia. Perithecia large, globose, black, the osti- 
ola minutely papillate. Asci cylindric, short-stalked, 150-170 x 
10-12 mic., 8-sporous, the spores obliquely uniseriate, with slen¬ 
der delicate paraphyses; spores elliptic-fusoid, inaequilateral, 
brown, 20-27 x 9-11 mic. 
Growing on the surface of old soft wood of Acer, Lirioden- 
dron, etc. The stromata irregular in outline, composed of two 
or three to many perithecia; the perithecia o.7-1.0 mm. in diam¬ 
eter.
