Tortulomyces thailandicus gen. et sp nov and Nitschkia siamensis sp nov (Coronophorales, Ascomycota) from northern Thailand

Two new species collected in northern Thailand are herein described and discussed. Tortulomyces thailandicus is the type of a new genus characterized by a combination of such features as a dense subiculum, non-ostiolate ascomata, two kinds of paraphyses (filiform and bead-like), and 1-septate, brown ascospores. Nitschkia siamensis has non-ostiolate, turbinate and stalked ascomata and hyaline, often slightly curved, 1-septate ascospores. (C) 2012 The Mycological Society of Japan. Published by Elsevier B. V.
