Bab. in ramulis emortuis Wistariae sinensis, Bagneres de 

 Luchon. Obviously not a further development of the Diplodia, 

 since the sporophores are merely the inner cells of the pycnidial 

 wall, and although the young spores are 1-septate (as usual) 

 yet they are then quite unlike those of the Diplodia, being pale 

 and translucent, not fuliginous. 



Microdiplodia Wistariae, Grove sp. n. 



Pycnidia sparsa, usque 250 /*. longa, rotundata vel oblonga, 

 tecta, dein rima erumpentia, nigrescentia, contextu molli, minute 

 parenchymatico. Sporulae oblongae vel ovali-fusoideae, altero 

 saltern apice attenuata, dilute brunneolae, 1-septatae, non con- 

 striclae, 6-8 x 2*5-3 u, sporophoris subulatis, spora paullo 

 longioribus suffultae. (Fig. 16).

The texture of the pycnidium is very similar to that of the 

 Camarosporium. Exactly the same fungus was found intimately 

 mixed with Botryosphaeria Wistariae, Sacc on a specimen from 

 Aiken, South Carolina (H. W. Ravenel). The probability is 

 that all the species mentioned here on Wistaria are stages of that 



pyrenomycete.

Under the name Sphaeropsis hyalina Berkeley issued three 

 specimens, as follows: — 



I. On Fraxinus americana, Pennsylvania, Michener (Herb. 

 Berk. no. 4201!). This is young Diplodia inqvinans, "Westd. 

 Mature brown 1-septate spores, measuring 25-30 x 10-15 p., 

 are to be found mixed with the nearly hyaline spores of which 

 Berkeley makes a sketch. The pvcnidia stand mostly singly, 

 as they often do in British specimens. But in other specimens 

 every possible stage can be observed on the some branch, be- 

 tween this and Botryodiplodia Fraxini, Sacc, and an extensive 

 investigation of numerous examples from many quarters has 

 convinced me that the following are all synonyms of one and 

 the same species, in varying states of growth :
