Stromata flattened pulvinate, up to 2-5 mm. diam. pmkish 

 red, usually \dth a thin, white, superficial layer, becoming pale 

 brown, tomentose, compact internall}-, generally surrounded b}^ 

 a thin, white, powdery h}^othallus which extends over the leaf 

 for several millimetres. 



Perithecia produced on the h}pothallus, irregularh- dis- 

 tributed, sohtarv or in groups (but not united) , elongated conoid, 

 0-65-0-S mm. high, 0-3-0-4 mm. diameter below, purple-red, 

 dark-red bv transmitted light, apex brownish, clothed below 

 with interwo\-en hyphae arising from the stroma and from the 

 perithecium wall up to two-thirds the height of the perithecium, 

 the h\-phae from the perithecial wall tending to be moniliform; 

 asci long, cylindrical, capitate, eight-spored, 7/x diameter; spores 

 fihform, as' long as the slscus, septate, di\'iding into cylindrical 

 part-spores, 4-6 x 1-5-2 /x. 



Conidia on repent hyphae, 2 /a diameter, on the surface of the 

 stroma and h\-pothallus, lateral, sohtary on 

 minute crowded pedicels, hyaline, oval, 3 x 1-5^1, 

 or spherical, 1-2 /i diameter.

The above description is drawTi up from Thaxter s

collection contained numerous barren stromata. 



PatouiUard and Lagerheim gave the dimensions of the asci 

 as 700-800 X 6-7 /i, the part-spores ^Sl^ long, and the peri- 

 thecia, up to I mm. high; they stated that the stroma was white, 

 then rose, red, or rufous-brown. In describing the colour as 

 above, the sequence has been deduced from the changes in the 

 corresponding Ce3-lon species. 



The stroma consists of interwoven h^-phae which are not 

 fused into a solid or parench\Tnatous tissue. The h^-phae in the 

 interior are thick- walled or almost solid, flexuose, 3-4 ^ diameter, 

 irregular" sometimes attaining a diameter of 5/1, general!}' rough 

 with minute granules. At the exterior the h^-phae are of the 

 same character, 2-5 /u,, occasionally 6/x diameter, with, in 

 addition, very fine h^-phae 0-75^1 diameter. The fine h^-phae
