Abstract
The genus Helicostylum was restricted to two species, H. elegans and H. pulchrum, based on the phylogenetic species concept. Helicostylum species were ditinguished from other genera of Thamnidiaceae by the production of 1) relatively large, multispored, deliquesent-walled sporangia at the apices of the sporangiophores and 2) pedicellate, relatively small, persistent-walled sporangiola laterally from the sporangiophore itself or from lateral branchlets having elongate, sterile, spine-like terminations. In some cases a given sporangiophore bears only sporangia or sporangiola. The lateral, fertile branches arose singly, in pairs, or in verticels or pseudoverticels of three to 20. Zygospores were described for the first time for H. pulchrum. A new genus Kirkia was based on H. cordense, which lacks spinelike fertile branches and has an optimal growth temperature of 25 C vs slightly below 20 C for species of Helicostylum. A cladistic analysis using representative species of all sporangiate Thamnidiaceae demonstrated that Helicostylum and Kirkia resided in separate clades. Selected strains of all species of Helicostylum were included in the analysis. Helicostylum venustellum was considered a synonym of H. pulchrum. All taxa were illustrated with line drawings. Keys were provided to genera and species, and an extensive list of synonyms was presented.
