Remarks (public):Pouzar (1959) proposed the genus Cystosteruem on the basis of unique combination of numerous gloeocystidia, dimitic hyphal system with very scarce light-coloured skeletal hyphae, hard consistency of trama and inamyloid basidiospores. Presently the genus is represented by eight taxa worldwide (Mycobank, 2018). Earlier from India C. murrayi has been described from Himachal Pradesh (Rattan 1977; Kaur 2018) and Uttarakhand (Sanyal 2014). C. murrayi differs from C. sirmaurrayi in having tuberculate hymenial surface and comparatively narrower basidiospores.

Description:Basidiocarp resupinate, effused, adnate, ≤340 µm thick in section; hymenial surface smooth but with minute scattered tubercles, white when fresh, becoming yellowish white to orange white on drying; margins thinning or indeterminate, paler concolorous. Hyphal system dimitic. Generative hyphae branched, with clamps, thin-walled, subhyaline up to 2.8 µm wide. Skeletal hyphae unbranched, aseptate, thick-walled, subhyaline up to 5.2 µm wide. Cystidia 26–44 × 7–8.5 µm, variable shape, generally with an obtuse apex, thin- to somewhat thick-walled, with basal clamp, embedded in the hymenium and subhymenium, not stained in sulphovanilin. Basidia 15–20 × 3.8–4.7 µm, subclavate to clavate, 4-sterigmate, with basal clamp; sterigmata up to 3.3 µm long. Basidiospores 3.3–4.2 × 2.3–3.3 µm, ellipsoid to broadly ellipsoid, apiculate, thin-walled, smooth, inamyloid, acyanophilous.
