Spores (2.8–)3.3–3.7–4.2(–5.6) × (2.5–)2.9–3.1–3.4(–4.2) µm (288/5/5), Q = (0.96–)1.07–1.19–1.32(–1.69), V = (10.2–)14.6–19.8–25.0(–46.1) μm 3, globose to subglobose or broadly ellipsoid in frontal and side view, wall up to 0.2–0.3 µm thick, smooth, colorless in L4; hilar appendix prominent, 0.5–0.8 µm long (Fig. 6c–f). Basidia 16–17.5 × 5–6 µm, mostly tetraspored but also bispored, clavate, sterigmata up to 5 µm long. Hymenophoral trama regular to subregular, consisting of up to 8 µm wide hyphae, colorless in L4. Hymenial cystidia absent. Pileipellis suprapellis as a quite compact (dense) cutis of broadly ellipsoid up to 16 µm wide hyphae mixed with cylindrical, up to 8 µm wide hyphae, with rounded apex, slightly gelatinized, smooth, sometimes ascendant and forming small trichodermic patches; subpellis formed by broadly ellipsoid, densely septate hyphae up to 10 µm wide (Fig. 5a–h). Pigments brownish, intracellular. Stipitipellis of cylindrical, up to 6 µm wide hyphae (Fig. 6a). Stipititrama of up to 16 µm wide hyphae. Caulocystidia usually present, clustered, versiform, thin-walled, colorless, up to 6 µm wide (Fig. 6b). Clamp-connections absent everywhere.

Habitat dan peran ekologis

Collybia pillodii was described and illustrated by the French mycologist Lucien Quélet (1890) from Jura hills as a very small entirely violet species with a campanulate to convex pruinose pileus, whitish pileus margin, adnate and distant lamellae paler than the pileus, a fistulous and slender rooting stipe bristling at the base with white and radiant rhizoids, very thin violaceous context, and minute subglobose to ovoid spores. He reported its spores as minutely aculeate (“finement aculeolée”), but his observation was probably incorrect because it was not confirmed by all the subsequent authors who observed always smooth spores. The species was later described in detail by Kühner and Romagnesi (1954), who suggested its possibly placement in Tricholoma section Liposperma. Favre (1960) believed that the species was better placed within the tribe Orcellées (see below) in sense of Kühner (see Kühner and Romagnesi 1953, Kühner 1969 = Entolomataceae). When Singer (1938) described Baeospora oligophylla he did not compare it to Collybia pillodii described 48 years earlier by Quélet (1890). He merely noted that the latter species probably also belongs to the genus Baeospora Singer. Then, when Singer (1942) established the genus Pseudobaeospora for the species of Baeospora with dextrinoid spores, he included only B. oligophylla.
