Neither Pseudoarmillariella nor Arrhenia – might be an unknown genus

This is not Pseudoarmillariella as it does not have crowded, forked lamellae with red staining reaction, nor Arrhenia obscurata as that species lacks orange-yellow pigments (consulted Scott Redhead who agrees). The closest BLAST match for the ITS is to some Leucocybe species, but it does not resemble them. Suggest collecting more with vouchered specimens for micromorphological analyses.
