Public Note:
This was originally described with the type on Carmichaelia grandiflora (= C. arborea) [with the host identification changed to C. sp. by Dingley 1969] and the paratype on Notospartium carmichaelia (=C. carmichaeliae).Without a big survey I think it must remain uncertain if there is just a single species of phomopsis present across multiple species in the genus Carmichaelia, with the additional difficulty of much synonymy and misidentification in this plant group. The record reported here is the result of looking on just a few plants of C. australis on the Port Hills (leg. Peter Heenan). It is associated with a branch die-back and very common there. This evidence suggests P. cunninghamii sensu lato (ie Phomopsis on Carmichaelia) must be considered common but not noticed. The description by Gadgil seems at odds with the original by Sydow which I read as 'pycnidia densely aggregated, often two or three joined, and then more or less flattened-conoid, of different sizes, mostly 250-400 diam., occasionally indistinctly raised ostiolate. Wall ca. 15-25 u thick, of small cells over a context of more or less intensely olivaceous-brown material, and on the inner surface paler hyaline; spores oblong-fusoid, tapering at both ends, but obtuse, straight, rarely slightly unequilateral, continuous, hyaline, 6-8 x 2 - 2.5 um; sporophores densely packed, simple, bacillate, mostly distinctly attenuated above, 8-12 u, rarely up to 15 x 1-1,5 u broad.', i.e. not stromatic and not multi-loculate, which anyhow would be unusual for a phomopsis I believe. This material with A conidia length=6.8–9.4µm (µ=8.2, σ=0.88), width=1.8–2.6µm (µ=2.2, σ=0.27), Q=3.0–5.2µm (µ=3.81, σ=0.72), n=11, and scolecoid B conidia. [Feb2013] culture back from ICMP for sequencing has no conidia. Looks like Phoma pinodella. Sequence unique, near Diaporthe from Coryneocarpus.
