PORES WITH THIN WALLS.
FOMES LACCATUS (Fig. 603). Pileus thick, applanate, with
uneven, dark reddish brown, strongly laccate crust. Context dark
brown (bay brown). Pores minute, long, with brown tissue and
yellow mouths. Spores truncate, obovate 6x12, with punctate
surface.
This is a European species unknown elsewhere. Except as to its thick, laccate
crust, it is similar to Fomes applanatus, but the pore layers are thicker (1> to 2 cm.
thick), the pore mouths yellow, and the plant is evidently of rapid growth. It occurs
only on beech as far as we know. It was not included in Fries' work, hence there is
hardly a definite tradition concerning it in European mycology. I have not seen
any of Kalchbrenner's specimens, but he gave a good name to it, Fomes laccatus,
and a good description, excepting he described the spores as globose and hyaline,
which was a slight discrepancy, considering it was Kalchbrenner. It is not a rare
plant in England. Cooke distributed it years ago as Fomes applanatus, and Plowright
sent it to Rabenhorst, who also distributed it. There is no evidence that Berkeley
ever knew it. Quelet met the plant and sent a specimen to Fries labeled Fomes
flaviporus, but it was never published under that name. His specimen also reached
Cooke, labeled Fomes resinosus, attributed to Schrader's vague description, which
does not entirely agree. Quelet so published it, and cites Rostkovius t. 34, an
evident error. Bresadola at first followed Quelet, but afterwards described it as a
new species Fomes Pfeifferi. We believe, on the sacred laws of priority, it should
be called Fomes resinosus (Schrader-McGinty), it being the only plant in Europe
that answers at all to the original "description" of this much-bandied species.
SPECIMENS. We have about twenty collections, all from Europe.
