rug>osa, obtusa, poro tandem lato pertusa, postremo dilapsa

The similarity of this specimen, in the texture of the pycni- 

 dium and the form of the spores, to my Pseudodiplodia corticis 

 (see Sacc, Syll. x. 409) leads me to place it in the 



same 



minuteness 



aria. Karat,, though with spores only half as wide as in that 

 species. 



SPECIES TO BE TRANSFERRED TO GLOEOSPORIUM, 



489. Phoma Aurantiorum, Sacc. 



There can be no doubt that Saccardo was right in thinking 

 this to be identical with his Gloeosporium intermedium, which 

 is, however, a mere form of G. Anrantiorum, Westd., concern- 

 ing which he was misled by Penzig. Three distinct exsiecata, 

 under the name Sphaeropsis Aurantiorum, on dry branches of 

 Citrus, were examined, viz., the original issue of Dr. Marcucci, 

 dated 1866, and Rabenh. Fung. Eur. no. 1330, both from gar- 

 dens, Tortoli, Italy, and also Bourn. Fung. Gall. no. 90, France, 

 dated 1878 :■ all gave the same result. There is no pycnidium; 

 the spores measure 14-17 x 5-6 /x. and the sporopliores are of 

 about the same length : both of them are those indicative of a 

 Gloeosporium. The synonymy will therefore be as follows: —

Berkeley's original specimen of G. Hendersonii (Herb. Berk. 

 no. 3642 S) is exactly the same as G. Aurantiorum ("Westd. Herb. 

 Crypt. Belg. no. 1188!), both bein<r on half-dead leaves, though 

 the descriptions given are somewhat different, and that given by 

 Penzig at second hand (Mich. ii. 447) is quite unlike, unless 

 one amends it by correcting the length of the spores from " 3 p " 

 to 13 p.. The original description of Westendorp (I.e.) gives the 

 spore-measurements as the equivalents of 10-15 x 5 /*. The
