Public Note:
Peter's original image doesn't show the distinct eccentric stipe. Gill tissue dextrinoid. Cap a hymendiderm with rotalis cells - Hygrometrici or Singer's neosessiles (for Desjardin = sicci/leonini). Clamped. Spores length=8.4-9.6µm (µ=9.0, σ=0.4), width=4.9-6.2µm (µ=5.6, σ=0.4), Q=1.5-1.9µm (µ=1.6, σ=0.1), n=12. Near Horak's unilamellatus. Singer's tenuissimus/spaniophyllus/sejunctus/neosessils. Pileus trama is not dextrinoid., leading to tenuissimus. For Antonin (Africa) this would have narrower spores and darker cap (but descriptions differ). For Desjardin it would be bigger, have non-marginate gills and this does have them. The name is invalid (non Schwein.)
