FUSCUS. CONTEXT BROWN.
FOMES TEXAN US. This is intermediate between Fomes igniarius and
Fomes pomaceus. It occurs on Juniper in the Southwest. The black, rimose surface
and general appearance of the plant is that of Fomes igniarius. The context color
is intermediate, perhaps close to pomaceus. The spores of all three are the same
(5-6, not 3-4, as described). Fomes texanus has yellow mycelium, agreeing with
Fomes pomaceus in this respect.
FOMES CINCHONENSIS. This, for me, is a large tropical form of Fomes
pomaceus, differing, as far as I can note, in its large size, but in no essential character,
context, color, spores, or setae. It also has the abundant yellowish, mycelial hyphae
overrunning the old tissue, which is a frequent feature of Fomes pomaceus.
Compare Fomes Robinsoniae on pag; 234. Should be entered here.
FOMES ROBUSTUS (Fig. 589). Pileus ungulate, with a hard,
rimose, black crust. Context light fulvous. Rhei color would be the
best name for it, being the color of commercial rhubarb root. It is
near to yellow ochre of Ridgway. Pores minute, with pore tissues
cpncolorous. Spores globose, hyaline, 7-8 mic., guttulate when fresh.
No setae found by me. (I am informed that setae have been noted
in a Swedish specimen.)
Fomes robustus grows fairly common in Europe on the oak. It was named by
ten (so I am told by Romell), but Karsten distributed it No. 95, labeled Polypigniarius.
Externally, it closely resembles Fomes igniarius, but there is a marked
