Chroogomphus subfulmineus

Chroogomphus subfulmineus is a basidiomycete fungus in the family Gomphidiaceae, described as new to science in 2018.
This species is closely related to "Chroogomphus fulmineus", but produces larger fruit bodies with generally duller colours, a deep yolk-yellow trama and an olivaceous stipe base. Microscopically, it has more narrow cystidia (av. range 13.8–14.8 μm) than "C. fulmineus" and broader spores (av. range 17.5–21.6 × 6.4–7.7 μm).
It is so far known from the island of Cyprus, Finland, and the United Kingdom.
