Entomosporium maculatuni. Lev. Five 5'ears ago Mr. G. F. Wilcox of Fair- port, N. Y., sent to the Universit}^ Quince leaves and fruits very much diseased by the above. The leaves were affected by circular brown spots from 1-3 millimetersin diameter, and the fruits had many Fig. 5.—Leaf of Quince with spots of £«i;owo5/>o^/«w;«ac-brown patcllCS frOm 3-7 ^''poRiEt Deh '^°''' '"'^^' °''''^ latter much magnified. j,,iiii,,,eters in diameter on the surface. At the centre of the areas in both were small perithecia (or ) containing the insect-like spores (fig. 5, sp.) of this fungus, and arising from the mycelium growing among the cells. These areas on the fruit were slightly sunken as if a finger had been pressed on them. Many of the fruits badly affected had cracked and all were un- marketable. We reported it as Morthicra Mespilii, Fuckel ; var. Cydoniae, Cooke and Ellis, the name by which it was usually known at that time. Saccardo has revived the earlier name ]:.n- tomosporium niaadahtm, Lev., which is given in his Sylloge Ftcn- goriim, III, p. 657, and by which it is now usually mentioned. For some j-ears it has been scarce on the Quince although it was abundant this^'ear in .some localities in New York.
