As far as can be judged from the brief description, tlie preceding 

 species is not distinct from tliis, 



22. Gl(eospokiu3i capsularu^i, Cke. & Hark., Grev. XII, p. 94. 

 Gregarious, punctif )rm, mouth lacerate-cleft. Spores cylindrical. 



obtuse at each end, slender, straight, continuous, hyaline, 18—20 x 2i 

 bursting out in pale, granular globules ("grumulos pallidos.") 

 On dead capsules of Eucalyptus, Calafornia (Harkness.) 



23. Gloeosporiu^i fusarioides, E. & K., Journ. Mycol. I, p. 3. 

 Acervulii — f mm. in diameter, subcuticular, scattered irregularly or 



collected in groups, in which case the part of the leaf occupied assumes 

 a dark brownish look. The spores ooze out on both surfaces of the leaf 

 but more abundantly above, being of an oblong-cylindrical shape, 20—30 

 X 5—6 /^-, filled with greenish granular matter and globose nuclei and are 

 borne on elongated cells (basidia) arising directly from the inner surface 

 of the hymeneal cavity. 



On fading leaves of Asclepias Covnuti, August, Kansas (Kellerman.) 



24. Glceosporium FRAxmEU^r, Pk., 35th Rep. ^. Y. St. Mus., p. 137. 

 Spots numerous, small, pale red with a darker or purplish-red border 



and usually with a minute, whitish center, nuclei (acervuli) few. Spores 

 obloiig-elliptical, colorless, 5—6 x 4 z^-, sometimes with a minute nucleus 

 at each end. 



On living leaves of Fraxinus pubescens, June, Albany, N. Y. (Peck.) 



25. Glceosporium affine, E. & K , Am. Nat. 1883. p. 1165, sub Phyl- 

 losticta. 



Spots light rusty-brown of irregular outline, 4—5 mm. with a nar- 

 row, dark brown, scarcely raised border. Acervuli amphigenous, pale, 

 125—200 fJ- in diameter, mostly situated on or near the nerves of the leaf. 

 Spores oblong, hyaline, 5 x li on basidia about 6 long. 



On living leaves of Sassafras, July, Ohio, (Kellerman.) 



26. Glceosporium salicis. West, Exs. 1269. 



Spots amphigenous, dark brown or nearly black, small (1 mm.), often 

 confluent. Acervuli covered, scattered or confluent ; cirrhi short, curved, 

 white. Spores oblong, slightly curved, continuous, with a nucleus or oil 

 globule at each end. We have seen no American specimens of this 

 species, but Prof. Peck reports it on leaves of Salix longifolia, North 

 Greenbush, N. Y., September, and sends the following note : 



"Our specimens have the spores either simple or 2— 3-nucleate and 

 generally a little thicker towards one end. In size they are 15—23 x 7i — 

 10 m. Very unlike G. salicinum, Pk., which is rather a Septogloeum, 

 though the septa are obscure." 



27. GLCEOSPORIU3I Glottidii, E. & M., n. s. 



In the single specimen seen, occupying the dead tip of the pod, the 

 dead portion obscurely limited by a dull purplish border. Acervuli 

 scattered, numerous, nearly black when dry, suborbicular, 250 in diam. 

 Spores varying from ovate to oblong and cyhndrical, 1—3 nucleate, the
