ZHURBENKO1 AND YOSHIHITO OHMURA2 ABSTRACT. – Capronia thamnoliae, Cercidospora thamnoliae and Cercidospora thamnoliicola are reported new to Japan; Endococcus thamnoliae new to Papua New Guinea; Merismatium thamnoliicola new to Norway; Polycoccum vermicularium new to Argentina, Australia, Colombia, Japan, Nepal and Papua New Guinea; Sphaerellothecium thamnoliae var. taimyricum new to Nepal; S. thamnoliae var. thamnoliae new to Australia, Falkland Islands, Japan and Papua New Guinea; Sphaeropezia santessonii new to Japan; Stigmidium frigidum new to Japan; Thamnogalla crombiei new to Australia, Bhutan, India, Japan, Nepal, North Korea and Papua New Guinea. Cornutispora ciliata is newly reported from Thamnolia. Material of Polycoccum vermicularium is shown to be morphologically heterogeneous. KEYWORDS. – Biodiversity, biogeography, lichenicolous mycobiota. INTRODUCTION Thamnolia Ach. ex Shaer. (Icmadophilaceae) is among the host lichen genera with the highest diversity of known lichenicolous fungi (Diederich et al. 2018b). At least 26 species of these fungi have been documented from Thamnolia (Diederich et al. 2018a; Zhurbenko 2012, 2017; also herein). Although thamnoliicolous fungi have been specifically treated by Ihlen (1995) and Zhurbenko (2012), including an identification key presented in the latter, their distribution and frequency is still poorly known. Here we provide new distributional records, range extensions and taxonomic notes on thamnoliicolous fungi that were found in conjunction with examining material at several major herbaria. MATERIALS AND METHODS This study is based on 81 specimens of lichenicolous fungi found on Thamnolia deposited in H (33 specimens) and TNS (48 specimens).
