Fistulinella wolfeana
Fistulinella wolfeana is a bolete fungus in the family Boletaceae found in eastern and southeastern Mexico, where it grows under pine and oak in mixed forest. It was described as new to science in 1991.
Description
Fistulinella wolfeana has pink pores and tubes, which bruise orange to ochraceous red when touched. Its cap is sticky. It measures 30-150 mm, and can be flat to concave or convex. It is brown with pink to violet hues, and smooth. Its pores are 1-1.5 mm in diameter. Individual tubes are 7-20 mm long and white, though becoming pink with age. The stipe is dotted brown, and cylindrical, though it can have a bulbous base. The flesh of Fistulinella wolfeana is white, tending towards pink at its cap, or yellow at the base of its stipe. Its taste is mild.Its spores measure 10-14 by 4.5-6 microns. They are yellow to ochre and roughly spindle-shaped, with some having a slight depression at the suprahilar plage. The basidia measure 23-28 x 9-11 microns, and have 4 spores each. The pleurocystidia measure 36-55 by 6-12 microns, and are spindle-shaped. They are transparent to yellow-tinted in KOH and have a red hue in Melzer's reagent. The cheilocystidia measure 38-60 x 5-12 microns, and have a similar shape, though they have an ochraceous colour.
Distribution and Ecology
Fistulinella wolfeana is found mainly along the Trans-Mexican Volcanic Belt and part of the Sierra Madre del Sur mountain range in the states of Jalisco, Estado de Mexico, Guanajuato, Hidalgo, Morelos, Queretaro and Oaxaca. Its extent of occupancy is 150,000 km2.Fistulinella wolfeana fruits solitarily and scattered. It is assumed to be ectomycorrhizal with Quercus liebmanii, Q. scytophylla and other Quercus species. It prefers altitudes of 1500-2300 meters.
