Notes

The species is distinguished from similar species as Rigidoporus microporus by the presence of cystidia. This is the first record of the species for Tolima.

Diagnosis

Basidiome pileate, in some cases resupinate, solitary to imbricate, sessile (Fig. 1 I). Pileus concentrically zonate-sulcate, pale orange to reddish-brown and velutinate. Pore surface bright orange to greyish-brown. Pores round to angular, 6-13 per mm. Hyphal structure monomitic; generative hyphae with simple septa, moderately branched, thin to thick-walled, sometimes similar to skeletal hyphae, but with simple septa. Cystidia rare and encrusted. Cystidioles pointed and abundant. Basidiospores subglobose to globose, hyaline, smooth, negative in Melzer’s Reagent, 3.9-6.2 × 3.6-5.5 µm.
