FIG. 10 in Russula (Basidiomycota, Russulales, Russulaceae) subsection Roseinae "down under"

FIG. 10. — Russula koniamboensis Buyck, sp. nov. (holotype: 722/BB09.022). Details of the pileipellis. Note that all capitate-mucronate endings are optically empty; these are not pileocystidia, notwithstanding they are morphologically very similar to the pileocystidia of species in subgenus Heterophyllidiae Romagn., while all terminal cells of primordial hyphae are obtuse-rounded at their apex and possess refringent contents reminiscent of typical pileocystidia. Drawings B. Duhem. Scale bar: 20 µm.
