Remarks (internal):The most closely related species to D. kuehneroides is D. kuehneri (Boid. & Lanq.) Hjortst. Gloeocystidia are SA + in fruit bodies of D. kuehneroides and SA - in those of D. kuehneri, although the latter was found to have SA + gloeocystidia in culture (Boidin et al. 1991). Incompatibility between these two species was demonstrated by Boidin et al. (1991).
Basidiospore widths are somewhat variable in this species. For instance, in specimen Lin 295 the range of width of basidiospores is 3.2-4.0 µm, while it is 3.0-3.5 in specimen Wu 910725-21 (both measurements from spore-prints). These two specimens were shown to be intercompatible in this study. Wu 910725-21 was compatible with LY 14314 (holotype of D. kuehneroides), confirming the identity of the Taiwan specimens as D. kuehneroides

Description:Duportella kuehneroides Boidin, Lanquetin & Gilles, Bull. Soc. Mycol. France 107:98. 1991 Figures 1 A-C & 2
Fruit body effused, adnate, membranaceous, 70-170 µm thick in section. Hymenial surface grayish brown or purplish gray, smooth or slightly tuberculate, usually cracked; margin fairly determinate, brown, of an immature zone.
Hyphal system dimitic; generative hyphae nodose-septate. Subiculum bi-layered, composed of basal layer and medullary layer. Basal Iayer with compact texture, up to ca. 25 µm thick, sometimes indistinct; generative hyphae subhyaline or brownish, 2.5-4.0 µm diam, with thin to ca. 1 µm thick walls, usually glued together. Medullary layer with fairly dense texture; generative hyphae hyaline, usually indistinct, 2-3 µm diam, thin-walled. Subhymenium not clearly differentiated, thickening. Pseudosetae very numerous, immersed or projecting, overlapping in subiculum and subhymenium, brownish, apically encrusted, secondary septa occasional, 25-55 x 4-8 µm, with 0.5-2.5 µm thick walls, sometimes branched laterally. Gloeocystidia immersed or projecting, hyaline, fusiform or cylindrical, 30-60 x 7-11 µm, with 0.5-1.5 µm thick walls, SA +. Basidia narrowly clavate, 22-32 x 5-6 µm, 4-sterigmate. Basidiospores suballantoid or cylindrical, smooth, thin-walled, (6.2-) 6.8-8.5 (-9.0) x 3-4 µm (X = 7.69 ± 0.55 x 3.32 x 0.21 µm, n = 30, from spore-print of Wu 910725-21; X = 7.43 ± 0.83 x 3.60 ± 0.27 µm, n = 30, from spore-print of Lin 295), IKI-, CB-. Spore-print pale red.
Distribution: Reunion Island (Boidin et al. 1991) and Taiwan.
