Taxonomic reappraisal of Typhula variabilis, Typhula laschii, Typhula intermedia, and Typhula japonica

et al. 2015

We have redefined Typhula variabilis, T. laschii, T. intermedia, and T. japonica on the basis of morphological and molecular evidence. Typhula variabilis, T. laschii, and T. intermedia, hitherto regarded as synonymous, were compared by critical observations of sclerotial rind cells. Rind cells of T. variabilis were thick and plateaued in the center, whereas of T. laschii had a ridge in the center. An isolate from winter wheat that we had previously identified as T. variabilis was reidentified as T. intermedia because it failed to mate with T. variabilis, even though rind cells of T. intermedia were digitate and occasionally had double-line contours, as in the case of T. variabilis. Sequencing of the internal transcribed spacer regions, including 5.8S, supported these differences, indicating that T. variabilis, T. laschii, and T. intermedia are separate species. Typhula japonica was characterized by two-spored basidia and basidiospores that often remained agglutinated with each other and germinated on basidiocarps. Its single basidiospores normally developed into dikaryotic mycelia and rarely into monokaryotic mycelia. (C) 2015 The Mycological Society of Japan. Published by Elsevier B.V. All rights reserved

“…Typhula japonica has two-spored basidia, as have Typhula pulgensis (Khurana 1980) and T. ochraceosclerotiata (Olariaga and Salcedo 2009). These three species are probably closely related but require critical comparisons.…”

It has been reported that Sclerotium nivale Elenev causes winter damage (Sclerotium disease) to winter rye and turfgrass in the European part of Russia, Ukraine, and Estonia. This fungal name is invalid, and their biological characteristics are limited. Since all reports on this fungus and their disease are written in Russian and Estonian without our recent review (Tkachenko 2013), few phytopathologists outside the former Union of Soviet Socialist Republics know about this fungus. We found symptoms of Sclerotium disease in Moscow, Russia, and we obtained asexual spore-forming ascomycetous (absent clamp connections) and basidiomycetous (had clamp connections) isolates from their white sclerotia. “S. nivale” was composed of several fungal species of ascomycetes and basidiomycetes. The ascomycetous isolate had the ability to grow under the snow cover, and phylogenic analysis suggested that the ascomycetous isolate had high homology (98–99%) with genera of Karstenula and Paraphaeosphaeria. We previously reported sclerotia of Typhula sp. were formed ca. 2 weeks to 1 month after the snow melt, remained immature as mycelial aggregations after snow melt, and matured without snow. In addition, Paraphaeosphaeria included sclerotium parasites such as P. minitans. Several cold-adapted fungi infected basidiomycetous sclerotia of Typhula spp. and others. These findings suggested that ascomycetous S. nivale was the possibility of the mycoparasite under the snow.

“…The genus Typhula (Pers.) Fr., member of the Typhulaceae family, is represented in the world by over 70 species (Kirk et al 2008, Hoshino et al 2009, Olariaga & Salcedo 2009. The generic name is taken from Typha, the Latin name for reed-mace, which fruitbodies of this genus resemble (Massee 2015).…”
