Basidiocarps scattered, pustulate to pulvinate, sessile or sub-stipitate, pale orange, firm-gelatinous, 0.5 mm high, 1–2 mm diam. Sterile parts of basidiocarps covered with simple or branched, cylindrical, septate, hyaline, thin-walled, marginal hyphae. Internal hyphae branched, thin-walled, gelatinous, septate, hyaline, 2–3 μm diam, without clamp connections. Hymenium limited to superior surface of the basidiocarp. Probasidia cylindrical to clavate, sub-hyaline, 30–47 × 4–9 μm, becoming bifurcate. Basidiospores reniform, with an apiculum at the base, thin- or thick-walled, pale yellow, 12.5–18 × 5–9.5 μm (av. 15 × 6.5 μm; n = 20), 1–3-septate, germination by means of conidial production and germ tubes.
Culture characteristics — Colonies of the primary mycelium attaining about 6 mm diam, velvety, orange to white. Conidiogenous cells on vegetative hyphae, polyblastic, sympodial. Conidia subglobose, 6 × 3 μm.
Specimens examined. japan, Nara, Kasuga Shrine, on dead branches of Podocarpus nagi, 23 Apr. 2006, T. Shirouzu, TNS-F-15721 (HNo.237); Mt Kasuga, on dead branches of an unknown broad-leaved tree, 23 Apr. 2006, T. Shirouzu, TNS-F-15720 (HNo.224), culture MAFF240135.
Notes — Dacrymyces minor is characterised by relatively small, pustulate to pulvinate basidiocarps, hyphae without clamp connections, and thin- or thick-walled, 1–3-septate basidiospores. This species was first recorded from Japan by Kobayasi (1939a).
