Panellus atrofulvus G. Stev. 1964

Description

K(M) 235252, Stevenson 1291. The dark pileus colour alone seems adequate to separate from H. veluticeps. The densley tomentose cap and stipe consiste of thic-walled hyphae. No cystidial elements seen. Cheilocystidia branched. Spores deeply amyloid length=7.7–10.4µm (µ=8.7, σ=0.66), width=4.2–5.2µm (µ=4.6, σ=0.31), Q=1.7–2.2µm (µ=1.89, σ=0.12), n=20. Adequate phylogeny data for overseas similar species currently lacking.
