Dacrymyces aureosporus Shirouzu & Tokum., Persoonia 23: 22 (2009)

Hierarchy: Basidiomycota, Dacrymycetales , Dacrymycetaceae

Specimens examined: KOREA, Gyeonggi-do, Goyangsi, Seooreung , 37°38 ʹ 20 ʺ N, 126°54 ʹ 02 ʺ E, 18 Jun 2015, Hyun Lee, Young Woon Lim, SFC20150618-05 (GenBank accession No. MF 445221), on the rotten log of deciduous tree .

Basidiocarps gregarious, sometimes joined together, turbinate to convoluted, sessile or stipitate bearing a cerebriform pileus, orange white (6A2) to pale red (7A3), gelatinous, 1-3 mm high, 1-6 mm diameter.

Sterile parts of basidiocarps covered with simple cylindrical to clavate, septate, hyaline, thin walled marginal hyphae. Internal hyphae thin-walled, branched, septate, hyaline, 2.5-3 μm diam. All hyphae without clamp connections. Basidia 41.1-53.5-72.2 × 4.5-5.3-6.1 μm, cylindrical, bifurcate. Probasidia similar to basidia, becoming bifurcate. Basidiospores 17.7-19.9-22.4 × 7.1- 8.0-9.7 μm, Q = 2.16-2.48-2.86, allantoid, 7-septate, thin-walled

Remarks: Dacrymyces aureosporus is characterized by turbinate to convoluted basidiocarps, and 7-septate basidiospores. This species is similar to D. chrysospermus . However, D. chrysospermus has terminal cells with thick wall on the sterile part of the basidiocarps ( Shirouzu et al., 2009) while D. aureosporus has thin-walled terminal cells.
