TRAMETES ABIETIS. Pilei thin, imbricate, often entirely
resupinate or with a reflexed border. The large daedaloid pores
(Fig. 609) and other characters are exactly as in Fomes pini, of which
I consider it only a thin form. It occurs in northern Europe, and has
been confused with Trametes piceina of the United States. Our
figure (610) can be taken to represent it. excepting as to size of pores.
Specimens. Sweden, C. G. Lloyd.
TRAMETES PICEINA (Fig. 610). Pileus thin, often imbricate,
woody, 1-2 inches broad, often resupinate with reflexed margin.
Surface tomentose, sulcate, zones, dark. Context Sudan brown.
Pores small, 3-4 to a mm., round, regular, appearing hiascent and irregular
when growing in an oblique position. Hymenium yellow
when fresh, becoming brownish. Setae numerous, slender. Spores
globose, 5-8 mic., hyaline.
This is a frequent species on the spruce in our Northern States.
Von Schrenk records it on various coniferous trees (in addition to
spruce) and states that it causes a common and destructive disease
in our northern forests. He considers it same as Trametes Abietis of
Europe as a variety of Fomes pini, but our American plant with its
(usually) minute pores is well distinct and worthy of a separate name.
We have two collections, however, that have larger pores which
rather invalidate the argument. The plant was named by Peck as
Polyporus, afterwards changed to Trametes, and was compiled in
Saccardo as Polystictus (sic).
Specimens. Many from H. D. House, State Botanist of New York, also several other collectors,
all from Canada or our Northern States. Mr. House sends also some cotype material. We have eighteen
collections, all with minute pores except two.
SECTION 71. CONTEXT BROWN. SPORES COLORED.
SETAE PRESENT.
FOMES ENDOTHEIUS. As this is exactly the same plant as Fomes rimosus,
excepting smoother crust, I had supposed the type of endotheius at Kew was the
same as Fomes rimosus, the surface not rimose, due to young condition of the specimens.
Additional specimens, however, from the Philippines indicate that the
surface does not become rimose, even when old. Hence Berkeley's species may
be maintained on this feature. As to context color, pores, spores, etc., it is exactly
the same as Fomes rimosus. It \vas discovered by Murrill to be a "new species,"
and called Fomes Merrillii.
FOMES FASTUOSUS. Specimens recently received Irom the Philippines
throw additional light on Fomes fastuosus (page 250) and Fomes pseudosenex
(p. 255). They both have same context and spores. The former has but one layer
of pores and context, is lighter, but in the latter the darker context may be due to
age. Fomes fastuosus may be a young condition of Fomes pseudosenex, but even
should that prove true we would prefer taking Murrill's name, as Leveille had no
definite idea in connection with his name and so-called three different species at
Paris. We hardly think Murrill's idea was much more definite, but still he was not
quite as bad as Leveille.
ADDITIONAL SYNONYMS.
Korthalsii, Java, Leveille. Type at Leiden is Polyporus sideroides (cfr. Letter
36). Leveille's naming at Paris, which is followed by Bresadola, is Fomes senex.
Also most of specimens so named from Philippines.
