Represented by three specimens (31308, 31386 and 31510), on canopy litter (pH 5.8 to 6.1). This species is considered to be cosmopolitan (Martin & Alexopoulos 1969) and has been recorded in virtually all surveys carried out for myxomycetes. It was first reported from New Zealand by Lister & Lister (1905).

Barbeyella minutissima Meyl. Fig. 2

Represented by two specimens (31397 and 3172), on canopy litter (pH 5.1 for both cultures in which this species appeared). The record for this species is the first for both New Zealand and the Southern Hemisphere (Stephenson & Novozhilov, unpublished data). In montane regions of the Northern Hemisphere where Barbeyella minutissima is most common, it is usually reported to be associated with a substrate complex represented by leafy liverworts on decaying conifer logs (Schnittler et al. 2000), but this was certainly not the case in the present study.
