Descriptions
Mucilopilus nothofagi (McNabb) Wolfe 1979
Fruitbodies two. Pilei 2 - 3.5 x 0.3 - 0.5 cm, smooth, uninterrupted, light gold. Stipe 5 - 5.2 x 0.2 - 0.4 cm, equal to subobclavate, concolorous with pileus, smooth. Pileus cuticle an interwoven ixotrichodermium; terminal cells 2.5 - 6.5 µm diam. (dm = 4 µm), hyaline in KOH, yellow in Melzer's. Tube trama, hyphae 2.5 - 8 µm diam. (dm = 8 µm), boletoid, hyaline in KOH, yellow in Melzer's. Clamp connections absent. Basidia 30 - 43 x 10.5 - 13 µm (Dm = 32.5 x 11.5 µm), thin-walled, clavate, hyaline in KOH, yellow in Melzer's. Pleurocystidia absent; cheilocystidia 19.5 - 47 x 4 - 8 µm (Dm = 34 x 6.5 µm), thin-walled with a few becoming thick-walled, equal, hyaline in KOH, yellow in Melzer's, abundant (Fig. 7); caulocystidia 26 - 39 x 5 - 9 µm (Dm = 31 x 8 µm), thin-walled, equal to clavate, hyaline to pale yellow in KOH, yellow in Melzer's. Spores 14 - 19.5 x 4 - 5 µm (Dm = 17 x 5 µm; E = 2.8 - 5.0; Em = 3.5), elliptical to subfusiform, inequilateral by a shallow suprahilar depression and adaxial swelling, pale yellow-cinnamon with green refractile inclusions in KOH, yellow-rust (pale dextrinoid) in Melzer's; surface smooth, walls continuous, surrounded by a hyaline membrane (Fig. 8); in deposit "Russet", light brown.
Observations. The ixotrichodermium of the pileus, the equal cheilocystidia, and the long, narrow spores (Em = 3.5) clearly indicate this specimen as being very similar to B. conicus, T. venezuelae, B. violaceiporus, and P. viscidus; this taxon differs from the other taxa in this genus by the absence of pleurocystidia. Because this taxon belongs in the genus Mucilopilus, the following new combination is proposed.
Mucilopilus nothofagi (McNabb) Wolfe, comb. nov.
