B. Context Dark Brown.
FOMES RIBIS (Fig. 594). Pileus thin, applanate, (5-8 mm.
thick.) Surface at first velvety, at length furrowed, uneven, with soft
ridges. Context cinnamon brown. Pores minute, concolorous. Setae,
none. Spores small, subglobose, 3 mic., colored.
Fomes ribis is quite a frequent species both in Europe and America
on the garden species of Ribis. It usually grows imbricate, near
the base of the plant. It occurs also on Euonymus and Lonicera in
Europe, never in America, to my knowledge. There are records of
it growing on Symphoricarpos in the United States. The Fomes on
Euonymus and Lonicera have distinct names in Europe, Fomes
Euonymi (generally spelled Evonymi in Europe) and Fomes Lonicerae.
They have long been held to be the same as Fomes ribis. My
observations are that the forms on Euonymus are usually of a brighter
color than that on Ribis, but otherwise are the same.
ILLUSTRATIONS.
Pi
Although a common plant, it has been rarely figured. The old figures,
Mora Damca, t. 1790, and Bulliard, t. 454, Fig. E, are both very inaccurate, if correctly referred.
: figure of Corda in Sturm's Flora, Vol. 3 t. 62, is the only good one I have noted.
SPECIMENS. Many, Europe and United States.
Compare Evonymi, Langloisii, I.onicerae, versatilis.
