Description: Original observation #339034 (Mushroom Observer)
Occurrence Remarks: A very late fruiting of three sporocarps growing in mixed deciduous woods of beech, tulip poplar and oak (all three tree species were in the immediate vicinity, but beech is the mostly likely host), no conifers. Two other bolete species were also discovered nearby and will be posted to MO shortly. I've never seen these boletes previously growing at this location. The largest cap (a post mature specimen, not collected) was 6-7" wide. The second largest fb had the following dimensions: Overall height = 14 cm Cap = 8.5 cm wide, convex/umbrella-shaped; 2 cm thick above the stipe Tube layer = 1.4 cm deep Stipe = 12 cm long, 1.9 cm wide at apex, 1.6 cm wide at narrowest point (in the middle), 2.2 cm wide at the base The overall morphology can be inferred from the photos. Nobilis is a good possibility, but these also fit the gestalt of gertudiae (e.g., the cap color and development of the yellow band in the stipe apex). More reason to suspect the two taxa are likely conspecific.
