Description

Growing on the lichen, Peltigera didactyla, on dry clay on upper level of bank below high water mark of reservoir among mosses and exotic grasses. Identified by Allison Knight - 3rd. photograph.

This is quite clearly Illosporiopsis christiansenii and a new record for New Zealand. Quite different to Illosporium carneum microscopically as it has conidia form a wound hyphal ball about 15-20um in diameter. Illosporium forms clusters of individual conidia in loose balls 50-100um in diameter. Chalk and cheese. So it looks like Galloway’s ‘Illosporium sensu lato’ is definitely sensu very lato. I could only find two collections of I. carneum in the herb here. One was correctly identified and the other was this.
