Trametopsis cervina

Trametopsis cervina (Schwein.) Tomsovský

[Trametes cervina, Funalia cervina]

Name
Tramète couleur de cerf (deer-colored trametes).
Etymology
Epithet = deer, fawn-colored. Genus = resembling Trametes (one who is thin).
Fruitbody
Annual, effused-reflexed to pileate (sessile), sometimes effused; up to 5 × 21 × 1.5 cm; texture tough corky. Can be in imbricate (overlapping) clusters. Upperside hairy (hirsute to strigose), somewhat zoned or not, color yellowish brown to grayish brown (pinkish buff to cinnamon-buff or clay color). Margin often paler. Pores irregular, somewhat maze-like, up to 1 mm across, 10 mm in depth; same color as context (flesh), buff, may turn dark brown with age; pore walls can become thin and split. Context pale buff, not zoned, up to 1 cm thick. Microscopic characters: dimitic; generative hyphae thin-walled, with clamps; skeletal hyphae thick-walled. Cystidia and other hymenium elements absent. Spores cylindrical, slightly curved (suballantoid), smooth, hyaline, non-amyloid, 7–9 × 2.5–3 µm. Spore print whitish.
Recognized by its pale yellowish brown brackets and large irregular pores that can split. Also its dimitic hyphal system (in trama) and cylindrical spores.
Similar species
This species is similar to a Trametes but seems more flexible. Trametes hirsuta and Cerrena unicolor have more densely hairy caps. Trametella gallica and Trametella trogii have coarsely hairy (strigose) caps. Spongipellis species have a monomitic hyphal system (generative hyphae thin or thick-walled with clamps) and subglobose spores (can be thick-walled). Also compare to Antrodia species, which have generally smaller brackets.
Ecology
White rot saprobe on dead hardwoods of many genera, rarely on conifers (Larix, Pinus, Pseudotsuga, Tsuga).
Phenology
Annual but brackets can overwinter.
Biogeography
Throughout eastern North America. Fewer reports in the west. Rare in Europe, known from Morocco and across Asia (though this may be more than one species).
Chicago Region status
Uncommon. There are several Harper collections (1900–1903) at BPI, UC. Leacock did not recognize it here until 2016 and again in 2018 but has since found unidentified and misidentified local collections from previous years.
Specimens examined
P. R. Leacock 13400, DuPage County, 2016, and PRL 13618, McHenry County, 2018. There are photos on Mushroom Observer. Further work in herbarium found more McHenry County collections from 2012 to 2015. Observations on iNaturalist have added Boone and Kane Counties, IL.
