Classification: Hamatocanthoscyphaceae, Helotiales, Leotiomycetidae, Leotiomycetes, Pezizomycotina, Ascomycota, Fungi
Etymology: Refers to its conidiophores with a multiseptate basal stipe and terminal phialides.
Saprobe on decaying plant material or in soil. Anamorph: Conidiophores solitary, erect, straight or slightly curved, cylindrical, multiseptate, brown, smooth, consisting of a basal multiseptate stipe and a terminated phialide, proliferation percurrently and/or sympodially. Conidiogenous cells integrated, terminal, phialidic, lageniform, brown, consisting of a venter and a collarette; transition from venter to collarette gradual or abrupt; venters subcylindrical; collarettes cylindrical. Conidia endogenous, hyaline, aseptate or uniseptate, cylindrical, with obtuse or truncate ends, extruded singly or in easily dispersible chains. Teleomorph: Unknown.
Ecology/substrate/host: Saprobe from soil and on decaying plant material, including needles of Pinus and Picea, rhizosphere, decaying grass.
Geographical distribution: Australia, Czech Republic, Finland, France, Germany, Poland, Sweden, UK and USA.
Notes: In the phylogenetic tree (Fig. 121; Wenping Wu et al. 2023), two species of Chalara s. lat., Chalara longipes and C. picea-abietis, clustered together as a strongly supported clade distinct from other known chalara-like fungi. Morphologically these two fungi are characterized by the well-developed conidiophores composed of a multiseptated main stalk and a terminal phialide, and hyaline, aseptate or septate conidia. The new genus Stipitochalara is created for them. These two species are morphologically related to Infundichalara, Constrictochalara and Cylindrochalara in forming well-developed conidiophores with multi-septate stipes and terminal phialides, cylindrical collarettes, and hyaline, aseptate or septate conidia. The new genus is indistinguishable from some known Chalara s. lat. species such as Chalara cylindrosperma, C. nothofagi and C. parvispora (Nag Raj and Kendrick 1975), but they are phylogenetically distinct. Three species are accepted in the genus.
Type species: Stipitochalara longipes (Preuss) Wenping Wu & Y.Z. Diao (≡ Chalara longipes (Preuss) Cooke).
Other accepted species: Species Fungorum – search Stipitochalara.
