Microporellus papuensis

Microporellus papuensis is a species of poroid fungus in the family Polyporaceae that was described as new in 2007. It was found growing from the ground in Madang, Papua New Guinea, and is only known to occur in the type locality.

Description

The fungus is characterised by fruit bodies featuring a cap that is laterally attached to the stipe, to shelf-like, to slightly convex in shape. The caps are whitish to greyish white; when fresh, there are some violet tints that disappear. Pores on the underside of the cap are medium-sized, numbering 3–5 per millimetre. Microscopic characteristics include the presence of cystidia in the hymenium, and more or less spherical to tear-shaped spores that measure 6.5–7.5 by 5.0–6.0 μm.
