961. Phoma Convallariae, Westd. 
PHoMOPSIS CONVALLARIAE, Grove. 
Pyenidia scattered, but often. two or three surrounded by 
a thin brownish Diaporthe-like line, oblong, blackish, covered by 
the epidermis which at length splits above, mostly imperfect, 
floored by the usual soft brownish parenchymatous tissue. 
Spores elliptic-fusoid, usually acute, biguttulate, the guttules 
distant from the extremities, occasionally appearing 1-septate, 
8-9 x 1:5-2-5y; sporophores linear-subulate, longer than the 
spore. 
On stems of Polygonatum multiflorum, Namur (Westd. Herb. 
Crypt. Belg. no. 1136! forma caulicola). The pycnidium consists 
chiefly of the discoloured matrix. 
Saccardo’s subspecies Phoma polygonatea (Mich. ii. 617), at 
least as represented in Roum. Fung. Gall. Exs. no. 3674!, does 
not seem to differ in any respect whatever. Evidently the 
pycnidium of a Diaporthe, and without doubt that of D. pardalota

Sphaeropsis maculata, Cooke & Hark. in Grevill. 1884, xii. 93. 
PLACOSPHAERIA MACULATA, Grove. 
Stroma widely effused, blackening the epidermis for several 
inches, whitish within ; pycnidial chambers up to 1 mm. diam., 
convex, very prominent, oblong, then erumpent with a black 
rugulose dise which is at length pierced by 1-4 whitish spots 
where the spore-mass bursts through the surface. Spores elliptic- 
fusoid, pointed at one or both ends, granular or 1-guttulate, 
8-10 x 3-5-5; sporophores crowded, subulate, up to l5p 
long. (Fig. 1.)
