longer ones sometimes a little curved, 9—16 x 3 /^-, on rather slender 

 basidia which are mostly a little shorter than the spores themselves.

28. Glceosporium Coryli (Desm.) Fhyllosticta corylina, & M., 

 in Am. Nat., Dec. 1884. 



Spots amphigenous, light brick red, 2—5 mm, or by confluence much 

 larger, often continuous along the margin of the leaf, accurately bounded 

 by a narrow, darker colored border. Acervuli mostly hypophyllous, 

 minute (90—120 /-'-) becoming nearly black. Spores oblong, 12—15 x-5—7 p-, 

 rounded at the ends and narrower in the middle, usually with two nuclei, 

 borne on short basidia. The spots are much larger than represented in 

 the figure in Fungi Italici 1019, but the spores are exactly as there repre- 

 sented. This is certainly not a Pliyllosticta, as there are no perithecia. 

 though the black acervuli much resemble perithecia. The trees on 

 which this fungus occurs were imported from England. We can not 

 say whether the same thing is found on our native species of Corylus.

29. Glceosporium phomiforme, Sacc. & Ell., Mich. II, p. 574. 

 Acervuli subgregarious, subcutaneous, fuscous, -} mm. diameter, per- 

 forating the epidermis, in the center. Conidia ovate-oblong, biguttulate, 

 hyaline, 5—6 x 3— 3i P-. Basidia acicular, 15—20 x 2 /^-, guttulate, hya- 

 line, arising from a cellular, dark straw-colored, proligerous stratum.

30. Glceosporium quercinum, West. 



In the Canadian Naturalist, X, p. 10, this species is credited to this 

 country by De Thuemen. We have seen no specimens, the only one in 

 our herbarium under this name (Fungi Gallici 2884), showing only a spot 

 caused by some larva burrowing under the epidermis. 



We copy the following description from Lambotte's Flore Mycol. 

 Beige : 



"Acervuli hypophyllous, dark reddish-brown, raising the epidermis 

 into pustules and spotting the leaf with dark red-brown. Spores elon- 

 gated-oval, cirrhi more or less distinctly orange-yellow." 



31. Glceosporium phomoides, Sacc. Mich. II,p. 540, F. Ital. tab. 1060. 

 Prof. J. C. Arthur of the Ag. Exp. Station at Geneva, N. Y., finds 



on the fruit of tomatoes what he considers to be this species. In the 3d 

 Annual Keport of the Station (1884). p. 381, he says of this fungus : 



"It corresponds very well with the figure and description of G. pho- 

 moides, Sacc, and may be identical with it. The fungus develops just 

 beneath and within the epidermis or skin of the fruit, and soon breaks 

 through it and produces great numbers of spores on the ends of the 

 protruding mycelium. To the naked eye, it only roughens the surface of 

 the fruit by the spores and ragged edges of the broken skin, but on cut- 

 ting open the tomato a firm, whitish mass reveals its extent."
