            <p>Holotype.</p>
            <p> FWI, Martinique:  Prêcheur , Anse Couleuvre, Couleuvre River, coastal rainforest, 14°50'13.05"N, 61°13'22.40"W, on submerged decorticated branch, 03 Jun. 2014, J. Fournier, MJF 14016; (ILLS 72402). </p>
            <p>Description.</p>
            <p> Ascomata 125-185 (-220)  µm diam, globose to subglobose, scattered or clustered in small groups, immersed-erumpent, the base remaining immersed in the substrate, brownish black appearing black when dry, attached to subtending  golden brown hyphae 8-22  µm diam, smooth, slightly constricted at septa; hyphae form cords developing under the wood surface and linking adjacent ascomata (Fig. 1  A–D ); wood beneath ascomata or at the periphery of the colony stained purple; ostiole  non-papillate , slightly depressed, pallid, rounded, minute, filled with hyaline periphyses (Fig. 1F). Peridium appearing roughened by protruding cells (Fig. 1B, D), 22-35  µm wide, two-layered: outermost layer textura angularis, composed of 1-2 rows of large thick-walled cells 8-18  µm in their greatest dimension, extending into hyphal appendages in places (Fig. 1F), more pigmented in upper half, inwardly lined by smaller hyaline flattened cells forming a textura prismatica (Fig. 1E, F). Asci 90-98  × 22.5-25  µm , bitunicate, with fissitunicate dehiscence occurring rarely, clavate to slightly obclavate, shortly pedicellate, 4-8-spored, ascospores 1-3 seriate (Fig. 2  G–I ); apex without (Fig. 2J) or with a faint truncate ocular chamber (Fig. 2K). Pseudoparaphyses 1-2.5  µm wide, cellular, often contorted, sparsely septate, rarely anastomosing, embedded in a gel matrix (Fig. 2G, L). Ascospores (23) 24-28 (31)  × (7) 8-9  µm , (mean = 26  × 8  µm ; n = 60), ellipsoid-fusiform, 1-septate, septum median to slightly submedian (0.53, N = 20), slightly constricted at the septum, upper cell wider and often apically pinched, lower cell obtusely rounded (Fig. 2H, I, M), contents densely guttulate; wall medium brown, minutely verrucose with warts partially in contact and forming a loose reticulate pattern (Fig. 2N), visible in hyaline immature ascospores; no sheath or appendages observed in aqueous nigrosin or India ink (Fig. 2O). </p>
            <p>Etymology.</p>
            <p> From Latin  “purpureus” referring to the characteristic staining of the substrate purple by this species. </p>
            <p>Anamorph.</p>
            <p>Not known.</p>
            <p>Known distribution.</p>
            <p>Martinique, Lesser Antilles (Known only from type locality thus far).</p>
