Bot. Fennici48: 37-48. One new genus, Tretomyces K.H. Larss., Kotir. & Saaren., and two new species, Tre tomyces microsporus Kotir., Saaren. & K.H. Larss., and Byssocorticium caeruleum Kotir., Saaren. & K.H. Larss. are described and illustrated. Three new combinations, Tretomyces lutescens (J. Erikss. & Ryvarden) K.H.
