No. 1.

Plate B.Fig. 4 should read Fig. 5, Fig. 5 should read Fig. 4.

No. 2.

Plate D.Fig. 3, the exposed inner surface of the cap, should be smooth, not ridged, as the straight lines in the engraving might suggest.

Plate V.For Lactarious read Lactarius.

No. 3.

Plate VIII.The red on the upper surface of the cap is too bright in tint. It should be a dull brick-red.

Plate IX.Fig. 6. The spores should be a deeper tint or brownish purple.

The spores as delineated on the plates represent a magnification of from 400 to 500 diameters.

Transcriber's Notes.

To avoid confusion, corrections noted above were not made to the plates or their captions.

"Membranaceous," "membraneous" and "membranous" all appear multiple times; I left them as is. Similarly for "Hynesboro" and "Hynesbury," "sebaceus" and "sebæceus," "subglobose" and "sub-globose," "center" and "centre," "network" and "net-work."

Both "Huseman" and "Husemann" appear; perhaps they refer to the same person, but I couldn't be sure, so I left them as is.

There is little consistency about when names are italicized or placed in quotes. Except where noted below, I left them as typeset in the original.
