Summary: Thelephora intybacea is similar to Thelephora terrestris but 1) the cap is pallid then rufous ferruginous then fuliginous, 2) the upper (inner) surface is felted, tomentose or scaly in narrow interrupted zones, and 3) the lower (outer) spore-bearing surface is papillate and wrinkled. Microscopic characters include angular-lobate spiny spores.
Microscopic: spores 8-12 x 6-9 microns, angular lobate, echinulate (finely spiny) with scattered subacute spines 0.5(1) microns high, yellow brown, one droplet; basidia 45-90 x 9-12 microns with 2-4 sterigmata 7-9 microns long; hyphae 2-7.5 microns wide, with clamp connections, becoming thick-walled; not cyanescent in KOH, (Corner)
Notes: Distribution includes WA, ID, ON, CT, DC, IA, MA, ME, MI, NC, NH, NY, OH, and VT, (Ginns), and Europe, South Africa, and New Zealand, (Corner). There are collections from BC at the University of British Columbia.
Habitat and Range
SIMILAR SPECIES
Thelephora mollissima has a smooth spore-bearing surface (Corner). T. intybacea is distinguished from ferruginous specimens of Thelephora terrestris "by the thicker and entire margin of the pileus and by the absence of free squamules", (Burt). See also SIMILAR section of Thelephora americana.
Habitat
"Ground in pine woods, growing up from the layer of fallen leaves; saprobic on rotten woody material of all kinds; in mixed woods", (Ginns), generally cespitose; in pine woods, (Corner), August to October, (Burt)
