Peniophora bonariensis C.E. Gómez

Basidiome resupinate, whitish, adnate, very thin, margin abrupt. Hyphal system monomitic, hyphae hyaline, with clamps. Hymenium a dense palisade of basidia, gloeocystidia, and lamprocystidia. Gloeocystidia abundant, tubular, often with a rooted base, few with an apical schizopapilla, 40–60 × 8–10 µm, distinctly thick-walled except at the apex, walls thickened up to 3 µm, with oleose contents. Lamprocystidia conical, mostly 25–35 × 10–15 µm, encrustation and basal part hyaline, less abundant than gleocystidia. Basidia clavate, 25–30 × 6–8 µm, with four sterigmata, with a basal clamp. Basidiospores cylindrical to suballantoid, 6.5–8 × 2.5–3 µm, smooth, hyaline, IKI- ( Fig. 11 ).

The species is characterized above all by the thick-walled gloeocystidia, often rooted at the base. The lamprocystidia, presence of clamps, and suballantoid basidiospores are also diagnostic. It is morphologically closely related to Peniophora crassitunicata Boidin, Lanq. & Gilles that differs in having much larger gloeocystidia and slightly smaller basidiospores. Martínez & Nakasone (2011) reported Peniophora crassitunicata from Uruguay. Peniophora bonariensis was recorded from northern Argentina ( Gómez & Loewenbaum 1976) and Guadeloupe ( Boidin et al. 1991).
