Specimen notes
Public Note:
[RFRM] Under Nothofagus, Ashley Gorge, 25/3/66 #73. Singly or in groups of 2-5, or occasionally caespitose. Pileus to 5.5cm diam. plano-convex, dry, distinctly velvety, occasionally the vertically arranged dermatocystidia aggregated into clumps. Margin entire, slightly projecting and sterile. Colour mid brown to chestnut. 6E5-F5. Stipe to 5cm long, thin, 3-6(9)mm diam. +-even but tapering basally, solid, fibrous, pallid, xxxx with faint brownish scabrosities, pallid fawn to mid-brown (as in cap but slightly paler), no annulus, sometimes pallid yellow at apex. Pores lemon yellow at firts becoming darker with age, irregularly angular, large 1-1.5mm diam, radially elongate around apex of stipe, depressed around apex and very occasionally decurrent in 2 specimens. Bluing greenish on damage. Context of pileus pallid yellow, blueing on exposure to air, but only after a while. Under Nothofagus solandri. [JAC] spores length=9.6-12.5µm (µ=11.0, s=0.59), width=4.1-5.1µm (µ=4.8, s=0.26), Q=2.1-2.6µm (µ=2.32, s=0.15), n=28. This material has distinctly yellow hyphae at the stem base, viz. X. lentistipitatus with stated (but not verified by type) yellow rhizomoprhs. The cap is minutely furfuraceous consisting of trichodermal cystidia, as McNabb says. The type of X. lentistipitatus has one cap showing a less pronounced furfuraceous surface. Accompanying comparative image shows the extremes between the two types.
