Resupinatus - Draft notes

Resupinatus found on pine:

Resupinatus cinerascens - This species was first noticed on eucalyptus. Spores 6 X 3.5 From Bioatnz "A species evidently closely related to P. applicatus and P. subapplicatus, but characterised more particularly by the cells on the pileus, a feature not apparently recorded in P. applicatus, from which it also differs in the gills being moderately close and grey and in the slightly smaller spores. The shape of the spores separates it from P. subapplicatus."

R. cinerascens  as spores that are sausage like 6 x 3.5 whereas R. subapplicatus are spherical 

Resupinatus vinosolividus - clear cross linking of gills
inat observation

Resupinatus violaceogriseus - sausage shaped spores, amorphic / roundish crystals. white fuzz on surface that is distinctive under the microscope "cap thick-walled glassy, coralloid hairs and gelatinous coralloid brown cap hyphae"
inat obs on pine. 

How to tell R cinerascens from R. violaceogriseus? R cinerascens was described in 1927 so hardly robust describtion. 

Other species in NZ, that are known to be present are all indigenous.

Resupinatus subapplicatus - described in Australia, recorded on indigenous vegetation. sproes spherical, 6 to 7 um

Resupinatus huia - not obviously gilled, more like crust or asco fungi

And the undescribed / un named species
Resupinatus sp. 'Howick (PDD 107004)' - spores sausage like

Resupinatus sp. 'Rimutaka (PDD 113403)' - no micro done

Resupinatus sp. 'Craigieburn (PDD 95777)' - spores not spherical but not obviously sausage like

Resupinatus sp. 'novaezelandiae (PDD 96584)' - spores spherical and crystals diamond like 

Resupinatus trichotis, this has the following note: The NZ taxon is undescribed (R. novaezelandiae nom. prov.) so I'm not sure what to make of this. There are two obs on inat that are from respected mycologists, so an indication that this name is still in play. 

Resupinatus merulioides has records in inat while the biotanz comment is: See R. sp. 'Punakaiki' but this doesn't appear to exist. So would appear that this name / species is still used. It is very distinctive with mesh like gills
