Exsiccati: Entyloma Linariae Schrot., on Linaria vulgaris , Ell. & Ev.,

Sori in leaves, forming hypopliyllous yellowish more or less 
defined spots, scattered or somewhat confluent, thin, oval to cir¬ 
cular, about ^-2 mm. in length ; spores hyaline to yellowish, chiefly 
subspherical or spherical, smooth, with evident double wall, 11-15 p 
in length ; conidia apparently lacking. 
Host: Linaria vulgaris , Conn., N. J. 
This species should be looked for on escaped Linaria introduced 
directly from Europe. While apparently very uncommon, it is 
likely to occur in abundance when found. The variety is more 
widely distributed and some botanists believe that they are hardly 
distinct.

Sori usually showing on both surfaces and thus more evident than 
with the species; spores often deeper tinted and larger, 13-16 /x, or 
most elongated sometimes 19 /x, in length; conidia described as 
27—30 /x x 2/x. 
Hosts : Veronica Americana , Colo., N. Y.; V. peregrina , Conn.,

This variety has been considered by some botanists as not distinct 
1 This has been called Entyloma Linariae forma (also var.) Veronicae Farl., 
but Farlow in his description in Bot. Gaz., 8 : 275, called it Entyloma Lin¬ 
ariae.
