met with, viz. spores with three or more cells variously arranged. See 

 Grove, Gardener's Chronicle, xxiv (1885), p. 180, f. 38. The mycelium is 

 probably perennial. 



Distribution : Central and Western Europe.

Teleutospores. Sori hypophy lions, on indefinite yellowish or 

 brownish concave spots, at first minute, 

 roundish, covered by the epidermis, in 

 orbicular clusters, then naked, con- 

 fluent, and forming a thick pulvinate 

 mass, ferruginous-brown ; spores ob- 

 long, rounded or attenuated at the 

 apex and much thickened (up to 8 /j,), 

 slightly constricted, rounded or attenu- 

 ated at the base, smooth, very pale 

 yellowish-brown, 30 — 54 x 14 — 21 //,; 

 pedicels hyaline, persistent, as much 

 as 80 fi, long. 



On Teucrium Scorodonia. July — October. Not common. 

 (Fig. 125.) 



Here, as in other Lepto-species, there seem to be two kinds of spores, 

 those which germinate at once and those which will not germinate till the 

 following year. The form on T. Chamaedrys (not yet found in Britain) 

 has been proved to be biologically distinct. 



Distribution : Central and Southern Europe.
