Etymology: Refers to its cylindrical venter and similarity with Chalara.
Anamorph: Conidiophores solitary, erect, cylindrical, consisting of 1–2-celled basal stalk and a terminal phialide, light greenish gray, smooth. Conidiogenous cells intergrade and terminal, or formed directly on vegetative hyphae, phialidic, lageniform, straight or slightly bent, light brown, smooth, gradually tapering towards the collarette, venter cylindrical, collarette cylindrical, transition from venter to collarette abrupt. Conidia cylindrical with rounded ends, rarely clavate, hyaline, aseptate, formed in long chains and sometimes connected with connectives (adapted from Koukol 2011). Teleomorph: unknown.
Ecology/substrate/host: Saprobe on needle of Picea abies.
Geographical distribution: Czech Republic and Lithuania.
Notes: Chalara hyalocuspica is a recently described species with short conidiophores consisting of 1–2-celled basal stalk and a terminal phialide, abrupt transition from venter to collarette, and hyaline, aseptate cylindrical conidia without basal frill (Koukol 2011). The phylogenetic analyses in this study showed that C. hyalocuspica was phylogenetically related to Stipitochalara, Infundichalara and Xenochalara in Hamatocanthoscyphaceae, and distinct from other chalara-like fungi. Morphologically it is hardly distinguished from Chalara s. str., except for its conidia sometimes with connectives.
Type species: Cylindrochalara hyalocuspica (Koukol) W.P. Wu & Y.Z. Diao.
Other accepted species: Species Fungorum – search Cylindrochalara.
