Mucilopilus viscidus var. macrosporus (McNabb) Wolfe 1979
Observations. This specimen is very similar to P. viscidus var. viscidus McNabb by the presence of the ixotrichodermium, basidial and cystidial characters. Spores of this specimen are longer by 5 µm (at the upper range limit) and by 2.5 µm at the Lm value that var. viscidus. The spore Em value is also greater than that of var. viscidus by 0.3. The spore character differences appear to be sufficiently different for varietal recognition. More studies of general collections will be necessary for confirmation of this conclusion.
Because this taxon belongs in the genus Mucilopilus the following new combination is proposed.
Mucilopilus viscidus var. macrosporus (McNabb) Wolfe, comb. nov.
Basionym: Porphyrellus viscidus var. macrosporus McNabb. 1967. New Zealand J. Bot. 5: 546.
