Notes

The colouration of the pore surface and the upper surface are characteristic of this species. It is found throughout Mexico and Central America. In Colombia, this collection represents the first record of the species for Tolima.

Diagnosis

Basidiomes annual, pileate, broadly attached, applanate. Pileus upper surface light brown to yellowish-grey, zonate, appressed velutinate to tomentose (Fig. 3 View Figure 3 K). Margin entire then lobed, pale fuscous vinaceous. Pore surface brown, pores angular 3-4 per mm, with irregular edge. Hyphal structure trimitic; generative hyphae with clamps, some rather thick-walled, hyaline; skeletal hyphae thick-walled, yellow, mostly parallel; binding hyphae tortuous. Cystidia clavate, apically encrusted. Hymenial cystidia with thin or slightly thickened walls, subclavate to subventricose, then obtuse apex with a crystal cap. Basidiospores ellipsoid, hyaline, negative in Melzer’s Reagent, 4.5-5.9 × 2.2-2.6 μm.
