Stereum Taxodii in Japan and Formosa

SUMMARY

Stereum taxodii, recently described from Taxodium distichum in the southern United States, occurs also on Cryptomeria japonica in Japan. Specimens from Torreya nucifera and Chamaecyparis formosensis in Japan and from C. formosensis in Formosa also seem to be S. taxodii. Occurrence of S. taxodii on Cryptomeria was established by examination of basidiocarps and cultures and on Torreya and Chamaecyparis by examination of basidiocarps. S. taxodii differs from S. sulcatum in the type of decay that it causes, in basidiocarp anatomy and morphology, and in cultural characteristics.
