Thailandiomyces Pinruan, Sakayaroj, Hyde & Jones

Index Fungorum number: IF511583


1 morphological species. Sexual morph: Ascomata scattered to gregarious, semi-immersed to superficial, globose, black, coriaceous, ostiolate, with long cylindrical necks, periphysate with short hyaline cells. Peridium composed of compressed cells of textura angularis, black outside, becoming brown inwardly. Paraphyses present but deliquescent, irregular in width, rarely septate, tapering towards the apices, embedded in a mucilaginous matrix. Asci 8-spored, unitunicate, cylindrical to clavate, apedicellate, free-floating, apically truncate, with a Jsubapical ring. Ascospores uniseptate, obliquely overlapping 2-seriate, fusoid, straight or broadly curved, with bipolar appendages, hyaline, smooth-walled. Asexual morph: Colonies on natural substrate effuse, black. Mycelium superficial. Conidiophores macronematous, mononematous, erect, brown, paler towards the apex, straight or flexuous, branched or unbranched. Conidiogenous cells enteroblastic, monophialidic, integrated, terminal, with a large and distinct collarette; collarette funnel-shaped. Conidia cylindrical, ellipsoid or obovoid, thick-walled, brown, aseptate.

Notes: The genus Thailandiomyces was introduced by Pinruan et al. (2008) to accommodate one ascomycete species collected from submerged trunk of Licuala longicalycata in Thailand. This species was apparently linked with a Craspedodidymum asexual morph in culture. This genus remains monotypic. Based on phylogenetic analyses, Suetrong et al. (2015) introduced a new family Tirisporellaceae, typified by a new genus Tirisporella E.B.G. Jones, K.D. Hyde & Alias. The genus Thailandiomyces phylogenetically resides in this family.
