Description:Lentinus proximus Berkeley & Curtis. 1869. J. Linn. Soc., Bot. 10:302. LECTOTYPE [hic designatus]: Cuba, C. Wright, no. 117, FH [! ].
Basidiomata two, moldy, lamellae partially eaten by insects. Pileus convex; surface ± smooth to fbrllose-, margin inrolled. Lamellae adnate-seceding, forming a "pseudocollarium", close, ± broad; margin entire or eroded; lamellulae in two tiers. Stipe central; ± widened at base, appearing sulcate, fibrillose. No evidence of veil or annulus.
Pileipellis a compact, repent layer of interwoven hyphae; hyphae 3-6 µm diam, hyaline singly, light brown in mass, with clamp connections; wall thin. Pileus trama loosely interwoven; hyphae 6-14 jun diam, hyaline, with clamp connections; wall 1-3 µm thick. Lamellar trama parallel; hyphae 4-12 µm diam, with clamp connections; wall 0.5-2 µm thick. Subhymenium poorly developed. Basidia 14-18 x 4-7 µm, clavate, often collapsed; sterigmata 1-4, often only two visible. Pleurocystidia not observed. Cheilocystidia (Fig. 8a) 12-33 x 5-12 µm, clavate to broadly clavate, often collapsed; apex obtuse, or irregularly lobed to branched. Stipe trama parallel; hyphae 2-10 µm diam, hyaline singly, straw colored in mass, with clamp connections; wall 0.8-2.4 µm thick. Caulocystidia not observed. Basidiospores (Fig. 8b) 5.6-7.2 x 2.4-3.2 µm, (n = 20, x = 6.4 x 2.9 µm, Q = 2.0-2.67, Qx = 2.19), ellipsoid, subovoid to subcylindrical, hyaline, inamyloid; wall thin, smooth.
Comment: All micromorphological characters conform to those described for A. boryanus (see above). The stipes of the basidiomata are very contaminated with mold and confirmation of caulocystidia was not possible. Previous workers did not expressly designate a lectotype for L. proximus (Pegler, 1975, 1983a), and now we propose collection Wright no. 117 to serve this function. We consider L. proximus to be a taxonomic synonym of A. boryanus.
