Comment here from user cooperj in 2018 stating it will one day be called Resupinatus novaezelandiae (observation is New Zealand; edit 3/2/25 this has since been rescinded):

Seasonality:

So far this has been collected every month of the year except April, July, and December. I would assume that given the distribution being North America and New Zealand currently that this species can occur in any given month of the year. The one Month that it was reported in New Zealand was March. It is reported more frequently June-November with a peak in August.

== Description ==
Growing few to many on hardwood debris, Willow (Salix), unknown vines (perhaps Vitis sp), Wisteria or Chinese Privet (Ligustrum sinense), or Tulip Poplar (Liriodendron tulipifera). Size of host ranging from "twig", to branch, or appearing to be on "logs". Caps ranging from 5mm to 25mm wide. Cap colors ranging from grayish white, two tone whitish and gray, grayish brown, and dark brownish gray. Growing like a pendulum/cupulate when resupinate, pleurotoid, kidney (reniform), or fan shaped (flabelliform). Hairs on the cap are notable at the point of attachment and sometimes reaching as far as 1/2-3/4 of the cap from the point of attachment to the margin. Hairs ranging from grayish in color when young to black at maturity. cap margin sometimes becoming scalloped in age. Metuloid cystidia present and visible at times with a macro lens. Spores: 4.3-5.0 x 2.9-3.4µm with a Mean of 4.6 x 3.2µm Q 1.3-1.6 with a Mean Q of1.5 N=11. Spores shaped ellipsoid to ovate to perhaps subglobose, but definitely not globose. Likely growing year-round with the peak season appearing to be August. Distribution perhaps cosmopolitan with sequences from North America and New Zealand.
