G. subpurpuratus is charecterized by the small fibrollise-scales on the disc, the greenish stains and the veil forming an annular zone. The green staining suggests that the species belongs the G. luteofolius/aeruginosus clade. It can be differentiated between G. aeruginosus by the lack of yellow and reddish spots, less scaly and lacks pleurocystidia and has a different type of caulocystidia.
