Abigail A. O’Brien confirms Dr. Duggar’s assertion that 
in case of some fungi the mycelium may be as resistant to moist 
heat as are the spores, by a series of experiments with Aspergillus 
flavus, Botrytis vulgaris, Rhizopus nigricans, Sterigmatocystis 
nigra and Pencillium, reported in the Bulletin of the Torrey 
Botanical Club (29:170-2), March 1902) under the title: Notes 
on the Comparative Resistance to High Temperature of the 
Spores and Mycelium of Certain Fungi. 
Elsie M. Kupfer reports a critical study of Urnula and 
Geopyxis in the Bulletin of the Torrey Botanical Club, 29:137- 
144. 1 pi. March 1902. The conclusion of the whole matter 
is: Urnula craterium Fr. represents a distinct genus from 
Geopyxis; Urnula terrestris (Niessl) Sacc. is not allied to U. 
craterium and is to be called Podophacidium xanthomelan; 
Urnula geaster Peck forms a new genus, Chorioactis, and is 
designated as C. geaster (Peck) Kupfer. 
The apothecia representing the ascigerous stage of 
Sclerotinia fructigena (Pers.) Schroet. (of which Monilia fruct- 
igena Pers. is the conidial form) were unknown till discovered 
on April 10th this year by J. B. S. Norton, who has given a note 
in Science (N. S. 16:34 4 July 1902) relative to the same, and 
an extended account of the observations and cultures with illus¬ 
trations in Trans. Acad. Sci. St. Louis, 12:91-7. 4 pi. 25 Aug. 
1902. 
The keys to the North American species of various 
genera of Fungi, on the dichotomal plan, which F. S. Earle is 
publishing in Torreya (1902) are to be highly commended to 
beginners in the study of those groups. The following have 
been issued: Lactarius, Hypholoma, Coprinus, Bolbitius, Gom- 
phidium, Nyctalis, Limacium, Hygrophorus, Russula. 
The occurrence of the larger form of Boletus felleus on 
stumps, at Alstead, N. H. is noted by H. Webster, Rhodora, 
4:187-8, Sept. 1902. 
F. S. Earle gives a note in Torreya (2:159-160, Oct. 1902) 
concerning a “much-named fungus,” pointing out that Cooke and 
Ellis’s Fusicladium fasciculatum published in Grevillea in 1878 
(6:88) had been renamed Scolecotrichum euphorbiae by Tracy 
and Earle, Piricularia euphorbiae by Atkinson, Cercosporidium 
euphorbiae by Earle, Scolecotrichum fasciculatum by Shear; 
and now it is Passalora fasciculata in the judgement of the same. 
Prof. Earle also transfers his Cercosporidium helleri to Passalora. 
VOLVARIA VOLVACEA FOUND IN EXTRAORDINARY abundance 
at Lawrence, Masachusetts, in a bed formed by dumping soiled 
cop, roving waste, bits of rag and paper, and night soil affords 
Francis H. Silsbee an opportunity of giving an amplified de-
