This is the first Calonectria that I am studying. It was found on Eucalyptus cone on the ground. I've checked some descriptions of Calonectria and this species from Malta seems to have two distinct characters: i) the stipe extensions, highly flexuous, have a tapering ending rather than a swollen vessicle; ii) the conidiospores are relatively small - 8-10um. I am not sure if the Conidiogenesis apparatus is 4- or 5- branched, the doubt arising at the phialides area. I am not sure if those amoeba-like cells mostly at the lower part of the species near the stipe are microconidia.

 Here is my first description of a Calonectria:


Perithecium an amber subgelatinous doliiform body sitting on a velvetly white mass of mycelia. Conidiophores with a stipe bearing fertile penicillate branches, stipe extensions, terminal vesicles and microconidia. Stipe septate, hyaline, smooth, 20-28 × 8–12 ?m; stipe extensions aseptate, flexuous, 120–300 ?m long, 2.2-2.6?m wide, terminating in tapering, rounded or rarely slightly swollen end without any obvious vesicles. Lateral stipe extensions (90 ? to the axis) also present. Conidiogenous apparatus 55–85 ?m long, and 80–160 ?m wide; primary branches aseptate, 16–20 ?m long; secondary branches aseptate, 10–12 ?m long; tertiary branches aseptate 6-9 ?m long; terminal phialides (possibly rebranching again), 12–17 ?m long, linear-fusiform to subfalcate. Macroconidia cylindrical, rounded at both ends, straight, aseptate (8–)9(–10) × 1.2 ?m. Microconidia irregularly rounded to ameboid, 6–8?m with a large central body.
