“…Heliocephala zimbabweensis resembles H. proliferans, and both differ from H. variabilis by having longer conidiophores (up to 210 µm in H. proliferans; up to 240 µm in H. zimbabweensis) and two-septate conidia with a very long and filiform rostrum, subsequently showing much longer conidia (10-200 µm in H. proliferans; 23-125 µm in H. zimbabweensis) than the species proposed here. Another feature exclusive to H. proliferans and H. zimbabweensis is the presence of a secondary cluster of conidiogenous cells at the apex of the conidial rostrum [8,29]. The great morphological similarity of these two species suggest they could be conspecific, but the lack of DNA data from the type is a handicap to elucidating the taxonomy of these fungi.…”

Heliocephala variabilis and Pseudopenidiella vietnamensis: Two New Hyphomycetous Species in the Microthyriaceae (Dothideomycetes) from Vietnam

et al. 2020

In a survey of microfungi from plant debris collected in Vietnam, two new hyphomycetous species were found, which belong to the genera Heliocephala and Pseudopenidiella and the family Microthyriaceae (Microthyriales, Dothideomycetes). Maximum Likelihood and Bayesian Inference sequence analyses of the internal transcribed spacers (ITS) and large subunit (LSU) of the ribosomal DNA barcodes allowed assessing the phylogenetic relationships of the new species with other species of the respective genera. Heliocephala variabilis sp. nov. was closely related to Heliocephala elegans, Heliocephala gracilis, and Heliocephala zimbabweensis, from which it was morphologically distinguished by its smaller conidiophores and non-rostrate conidia of up to four septa on the natural substratum. Pseudopenidiella vietnamensis sp. nov. was related to Pseudopenidiella piceae and Pseudopenidiella podocarpi and differed from the former principally by its lack of microcondiophores and from P. podocarpi by having larger macroconidiophores and smooth conidia. Key morphological features to distinguish the accepted species in Heliocephala and Pseudopenidiella are also provided. In addition, Pseudopenidiella pini was excluded from the genus on the basis of its morphological features.

“…As dimensões dos caracteres taxonômicos estão incluídas dentro dos limites da variação morfológica da espécie (Ellis 1971, Hughes 1949, Matsushima 1981, 1987 (Rao et al 1984) pela presença de rostro curvo e conídio liso, respectivamente. O comprimento do conidióforo do material examinado pode alcançar dimensão superior a do conidióforo do espécime-tipo (Decock et al 1998). A espécie é referida pela segunda vez para a ciência.…”

A new genus and species, Tretoheliocephala compacta, found on decaying leaves of an unidentified plant, is described and illustrated. It is characterized by macronematous, erect dark brown conidiophores with a compact cluster of globose, monotretic conidiogenous cells, which produce solitary or blastocatenate, ovoid, oblong, dolabriform, sub-obpyriform or obcuneiform, 0–2-septate, brown conidia.
