MycoBank no: — MB 817953 Etymology: — macabouense indicates the collecting place, Anse Grand Macabou, a coastal forest in the east side of the Martinique Island. Diagnosis: — differs from Sistotrema otagense by subceraceous basidiome, thin basal hyphae (2 ‒ 3 μm diam.), urniform basidia with long subcylindrical neck and narrow head, and more or less isodiametric spores. Description: — Basidiome annual, effused (10 × 7 cm), adnate, strongly attached to the wood, subceraceous, thin, as greyish bloom when fresh, then yellowish and porulose under lens (× 1000) in herbarium. Hymenium smooth. Margin not differentiated, without cords. Hyphal system monomitic, basal and subhymenial hyphae not differentiated, thin-walled, 2 ‒ 3 μm wide, with inconspicuous clamps at the septa. Cystidia not observed. Young basidia globose to pearshaped. Mature basidia scarce, typically urniform, with a short regular neck, basally clamped, 17 – 22 (– 25) × 6 ‒ 7 μm, 3.5 μm wide at the neck, content of basidia granular or including irregular bodies which are light refracting in phase contrast, with 4 ‒ 5 (‒ 6) thin sterigmata. Spore print white, spores subglobose, more or less isodiametric, with a small apiculus, 5 – 6 (‒ 6.5) × 4 – 5 μm, Qm = 1.2; thin-walled and smooth, acyanophilous, inamyloid, indextrinoid.
