pores; paraphyses capitate with a slender pedicel, thickened 
(up to 8 yz) above, 50—70 x 18—25 pu. 
Teleutospores. Sori hypophyllous, 
covered by the epidermis, small, about 
4 mm. diam., but united mto groups 
bounded by the veins, brown with a 
tinge of bluish-grey; spots brown on the 
upper surface; spores irregularly pris- 
matic, rounded at both ends, 25—40 
x 7—13 4; epispore thin, clear-brown, 
scarcely thickened above, with a barely 
perceptible apical germ-pore.

Fischer records the coma in Switzerland in May and June. The 
distinction of this species from the preceding one (apart from the ecidial 
host) lies in the teleuto-sori ; these are hypophyllous and subepidermal, 
while those of Jf, Larici-Caprearum are epiphyllous and subcuticular. It 
is not certain, however, that this distinction is absolute; Fischer in a 
culture on S. cinerea obtained a few teleuto-sori showing also the latter 
characters. There is a further difference in the form of the teleutospores.
