MEMORABILIA. 
Polyangium vitellinum. Specimen in Herb. Berk, received 
from Schweinitz is certainly Oligonema nitens, Lib., which does 
not seem to have been recorded for the United States. 
Theclospora bifida, Harlc. This has been so imperfectly de- 
scribed, and its whole character misunderstood, that it may be of 
service to indicate that on examination of authentic specimens from 
Dr. Harkness, it is identical with Inzengasa erythrospora, Borzi , in 
Pringsheim Jahrbucher, 1885, p. 450, with 2 plates, on which it is 
exhaustively delineated, and its perfect condition is ascosporous. 
Hence Theclospora is a spurious genus. 
Oligonema nitens. Lib. The specimens of Trichia circumscissa 
in Klotscli Herb. Myc. Ed. nova, No. 137, belong to this species. 
Trichia scabra. The specimens of Trichia chrysosperma in 
Roumeguere’s Fungi Gallici, No. 1683 (in our copy), belong to 
this species. 
Trichia varia. The specimens called Trichia chrysosperma in 
Karst. Fun. Fenn., No. 699, Mustiala, 1866. Those in Roume- 
guere’s Fungi Gallici, No. 1315, and those in Desmazieres’ Crypt. 
Fr., Ser. ii.. No. 260, all pertain to Trichia varia. 
Tubulina cylindrica (Bull.). The specimens called Siphotychium 
Casparyi, No. 2092, in Ellis and Everhart's N. Amer. Fungi, are 
typical Tubulina cylindrica (Bull.), whilst No. 2096 in the same 
series, called Tubulina cylindrica, differs in smaller spores, warted 
on one side, and may be called Tubulina microspora. 
Comatricha pulchella (Bab.). The Comatricha gracilis, Wing. 
in Ell. & Ev. N. Amer. Fungi, No. 2094, is identical with original 
type specimens of Comatricha pulchella. 
Trichia lateritia. Lev. The specimens of Trichia fallax, var. /3 
in Moug. & Nest., No. 578, and Trichia fragilis, f. botrytis, in Ellis 
& Everhart, N. Amer. Fungi, No. 2098, are all Trichia lateritia. 
Oligonema nitens, Lib. To this species must also be referred 
the Trichia Bavarica , Thum. of Thumen Myc. Univ., No. 1497. 
Trichia chrysosperma, Bull. Typical specimens of this species 
are contained in Rabh. Fung. Eur. No. 2137, under the name of 
Trichia varia. 
Hemiarcyria rubiformis (Bers.) Our specimens of Trichia pyri- 
formis, Boffm., issued in Saccardo Myc. Veneta, No. 962, are 
certainly this Hemiarcyria. 
Cercospora Styiosanthis, Ell. $ Ev., Journ. Myc. hi., 13 (1887), 
N.A. Fungi, No. 1764, is superseded by Cercospora Styiosanthis, 
Speg. FuDgi Guaranitici (1886), p. 216 — unless both are the same 
species.
