Notes — Dacrymyces pachysporus is characterised by its small pustulate to pulvinate basidiocarps, hyphae with clamp connections, and long thick-walled 0–3-septate basidiospores. This species is similar to D. sichuanensis and D. stillatus in having small pustulate to pulvinate sessile basidiocarps and 0–3-septate thick-walled basidiospores. Dacrymyces sichuanensis has shorter basidiospores (12.5–15.6  4.5–6.5 µm, Liu & Fan 1990) and branched dikaryophyses, the latter discerned based on a line drawing in Liu & Fan (1990). Dacrymyces stil­ latus has no clamp connections on hyphae (McNabb 1973, Shirouzu et al. 2009). Dacrymyces pachysporus is also similar to D. punctiformis in having small pustulate to pulvinate sessile basidiocarps and clamp connections on hyphae, but D. punctiformis has thin-walled smaller basidiospores (10–15  3.5–5 µm, as Dacrymyces tortus, McNabb 1973; 7–13  4–6 µm, Shirouzu et al. 2009). Samples accepted here as D. punctiformis and D. stillatus are phylogenetically distant from D. pachysporus (Fig. 1).
