Trametopsis cervina (Schwein.) Tomsovský

Czech Mycology 60 (1): 8 (2008)

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. Spongipellis species have a monomitic hyphal system (generative hyphae thin or thick-walled with clamps) and subglobose spores (can be thick-walled).
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:
Rare. There are several Harper collections (1900–1903) at BPI, UC. Leacock did not find it here until 2016 and again in 2018.
Type:
North Carolina, USA.
Taxonomy:
This species was also transferred to Antrodia, Coriolellus, Coriolus, Davidia, Diplomitoporus, Microporus, and Polystictus.
Specimens examined:
P. R. Leacock 13400, DuPage County, 2016, and PRL 13618, McHenry County, 2018. Carol Nelson has photos from Morton Grove, 2016, on Mushroom Observer.
