labyrinthiform or irregularly arranged, opening by a single pore 
(rarely by several pores) in the centre of a minute roundish 
greyish-yellow disc which alone is visible. Spores 4-5 x 1 uy, 
issuing in yellow, then saffron-coloured tendrils; sporophores 
linear, Steed branched or rather fasciculate at base, 20-25 p

Stromata scattered, 250-300 diam., black within and 
multilocular, causing a distinct roundish swelling beneath the 
epidermis, which finally pushes out, at the most prominent 
portion, only a minute grey disc, which is surrounded by the 
torn margin and at length pierced by a black ostiole; walls of 
the loculi rather thick, of dark olivaceous-brown tissue. Spores 
5-8 x 1-2; sporophores verticillately branched, or rather 
fasciculate on a basal cell, 18-20 x 2-5; branches acute.

The spermogone of Valsa Viburni Fckl. 
Saccardo called it a Dendrophoma merely because it has 
branched sporophores, but that is now known to be true of 
several species of Cytospora. It has no close affinity with 
C. pruinosa. C. Viburni Fautr. in Rev. awa 1891, p. 171, is 
probably only an early state of C. Lanta

Pyenidia scattered, conical, truncate, 0-5-1 mm. diam., 
with a rather large whitish furfuraceous disc at length marked 
with a minute black pore, dark-olive within, composed (when 
perfect) of many compact narrow radiately arranged pseudo- 
locelli or labyrinthiform chambers; walls of the locelli (under 
the miscroscope) thick and dark-brown, without a trace of 
green; no conceptacle. Spores 4-5 x 0-75-l yp, rather more 
acute at the ends than is usual; sporophores linear, not very 
crowded, more or less curved, 10-12 x 1 p.
