Note: 6 records without habitat information are excluded from the table below; habitat for these collections may or may not be provided in collectors' notes and other associated documents in the herbaria. 5 records from MICH (in purple font) representing Smith collections with no online habitat information have been checked against physical documents in the herbarium; see further notes below. Entries in red font appear to exclude the possibility of association with oak.
Collection documents for A. H. Smith 67602, in MICH (collected by B. Isaacs "under oak" in Michigan, 1963) raise the possibility that the collection does not represent Leccinum longicurvipes. Smith's accession book entry says "Boletus longicurvipes," but his collection label says "Boletus longicurvipes?" (Smith's question mark), and the collection notes read "Boletus longicurvipes? rubropunctus" in Smith's handwriting--above which someone else has written "Leccinum rubropunctum." The remainder of Smith's handwritten notes consist of a macrodescription:
Pileus 4 cm. broad, convex, surface viscid, ground color yellow (dingy ochraceous) this overlaid with a reddish brown reticulum, margin even. Context soft, white, taste mild, odor none, FeS04 - 0.
Tubes depressed, +/- 1 cm deep, [illegible; sides?] soon brown where cut; mouths dingy pale yellowish, staining brownish where bruised, round, +/- 2 per mm.
Stipe 7 cm. long, 7 mm at apex, equal, solid, pallid throughout, not staining when cut. Surface reddish in mid part, yellowish at apex and base, scabrous punctate but the ornamentation not darkening.
The colors of the cap and the bruising pore surface are suggestive of something besides Leccinum longicurvipes, but Peck's Boletus rubropunctus is not a good match for Smith's description, either.
Leccinum longicurvipes and Boletus longicurvipes were searched in all databases. No collections in TENN or BPI included habitat information. No collections of this taxon were found in OSU.
* NY = New York Botanical Garden; MICH = University of Michigan; TENN = University of Tennessee; OSU = Oregon State University; BPI = US National Fungus Collections. Differences in database scripting allow me to link individual records only in the case of NY; to see individuals in other herbaria, perform a search from the linked pages. Warning: some of the database scripting is archaic, and some of the servers are extremely slow.
