Holotype:— PHILIPPINES. Laguna Prov.: Los Banos , 15 July 1913, Dr. Copeland 1268 ( FH!).

The holotype specimen consists of 4 fragmented to intact basidiomes loose in the packet plus several badly fragmented basidiomes attached to woody substrate. Description of dried holotype: Basidiomes sessile, stipe absent, entirely pallid; lamellae well-developed, distant. Basidiospores 9.5–11.8 × 5.7–6.7 μm, broadly ellipsoid, lacking lateral bulges, smooth, hyaline, inamyloid, thin-walled. Basidia all 2-sterigmate, clamped. Basidioles clavate. Hymenial cystidia common on sides and edges of lamellae, 48–56 × 9–17.5 μm, ventricose with wall up to 0.8 μm thick (metuloids); apex smooth or capped with resinous incrustations; central axis smooth, hyaline. Pileipellis a thin Rameales -structure of diverticulate hyphae. Pileus trama of loosely interwoven hyphae 2–4 μm diam., hyaline, inamyloid, non-incrusted, clamped, embedded in a thick gelatinous matrix.

Status: The thick-walled, non-diverticulate hymenial cystidia in combination with ellipsoid (non-tetrahedral) basidiospores, the absence of a stipe, and strongly gelatinized tramal tissues indicate placement in Campanella . It should be noted that the holotype specimen has only 2-spored basidia. This makes the newly described variety C. simulans var. bispora Manimohn & Leelavathy superfluous.
