Catenularia macrospora S. Hughes, N. Z. J. Bot. 3: 143. 1965.

Habitat and geographical distribution.

Saprobe on decaying bark and wood of Dacrydium cupressinum , Fuscospora cliffortioides , Vitex lucens and other unknown hosts, known in Canada and New Zealand ( Hughes 1965).

Notes.

Catenularia macrospora has broadly obovoid to rounded-obconic, brown to dark brown conidia, 21-28 μm long, 19-28 μm wide at the apical end and 4-7 μm wide at the basal hilum, with (3-)4(-5) blunt corners when seen from above ( Hughes 1965). The conidial length is comparable with those of C. longispora and C. elsikii , but the former species differs in conidia narrowly rounded-obconic, narrower at the apical end (16.8-24 μm) with only (2-)3 corners. Although the length of conidia of C. elsikii and C. macrospora overlap and the number of corners is comparable, conidia of C. elsikii are slightly shorter and narrower in their upper range (23-24.5 × 21-24 μm) and narrower at the truncate base (3-4 μm) ( Pound et al. 2019).
