Anoectangium stracheyanum and Pseudocrossidium hornschuchianum (Pottiaceae, Bryophyta) in New Zealand

The first author has made six bryological expeditions to New Zealand, in 1959, 1968, 1973–1974, 1982, 1993 and 2000 (van Zanten 2019). In 1993 both authors collected in 106 sites, from both the North and South Island, resulting in a collection of about 1700 numbers. All the material is deposited in the herbarium Leiden (L), except for a smaller part that is at the moment not yet fully accessible. The first author did many preliminary identifications in his large New Zealand collections. Experiments were conducted from these collections utilizing the spores from fruiting material with several resulting publications, including van Zanten (1978) and van Zanten & Pócs (1981). The second author gathered mainly tiny acrocarpous mosses, on the whole pottiaceous material. We found it worthwhile to publish here two mosses that are apparently new records for New Zealand.
