SPORES HYALINE.
POLYPORUS FLORIFORMIS. Pileus thin, white, smooth
usually reduced at the base, unchanged in drying. Flesh thin, 1-2 mm ,
stiptic to taste. Pores small, round, or slightly elongated, pure white!
2-4 mic. long. Spores 3x4 mic., opaque.
This is a thin, white species, growing imbricate and pilei reduced
at the base, hence might be sought in Petaloides. It is rare both in
Europe and United States, and grows on acerous wood. It was well
illustrated by Bresadola (t. 63), who really named the plant, although
they write Quelet after it. It has a stiptic taste, and one of my correspondents
holds it to be Polyporus stipticus.
SPECIMENS. Sweden, C. G. L.; Michigan, Dr. C. H. Kauffman; England, H C Hawley

Polyporus undosus.
POLYPORUS LACTEUS (Fig. 656). Pileus effuso-reflexed,
white, rather thin, with rugulose, undulate surface. Flesh white, soft,
friable. Pores small, round, thin, but on the effused portion elongated,
unequal, angular. Spores 1^x4-5 mic., allantoid.
This to me is a rare plant, and so stated by Fries. I have but one
collection from Otto Jaap, Germany, which grew on poplar. There
is a poor cotype at Kew which I have compared with Jaap's collection
and found to be the same. It has the same flesh, surface, and spores
as Polyporus trabeus (compare page 301), but is a thin plant, largely
effusive behind, with the pores on the resupinate portion elongated
and angular. I believe it is too close to Polyporus trabeus, but in my
view it is not Polyporus trabeus of Fries; and the Fries' view is "Law"
nowadays.
SPECIMENS. Only one, from Otto Jaap, Germany.
ILLUSTRATIONS. Fries' Icones t. 182, 2, fig. 1. Surface shown more hispid than either our
specimen, or his specimen at Kew.
