Species Information
Summary:
Gloeophyllum trabeum has shingled, laterally fused, or rosette-like tough caps growing stemless on wood or timber, the upper surface warm sepia to umber brown and at first velvety to tomentose, with the ocher to umber brown hymenium densely gill-like or maze-like, or with small pores.
Odor:
none (Breitenbach)
Taste:
mild (Breitenbach)
Microscopic:
spores 6.5-9.5 x 3-4.5 microns, cylindric, smooth, inamyloid, colorless, thin-walled; basidia 4-spored, 20-25 x 6-7 microns, clavate, with basal clamp; cystidia mostly embedded in hymenium, up to 30 microns long, 4-5.5 microns wide, "fusoid to slightly clavate, obtuse or conical with an acute end", thin-walled, a few with resinous excretions as small globules, colorless or slightly golden yellow, "especially at the base where they may be more thick-walled"; hyphal system dimitic (trimitic?), generative hyphae 2.5-5 microns wide, wider in context than subhymenium, colorless, with clamp connections, skeletal hyphae dominating in the fruitbody, up to 6 microns wide, "golden-brown, thick-walled, straight and without sidebranches", "in the older parts of the context also a very few branched, thick-walled golden yellow hyphae which may represent poorly developed binding hyphae", (Gilbertson)
Spore Deposit:
white (Buczacki)

Habitat and Range
SIMILAR SPECIES
Gloeophyllum trabeum is told from other Gloeophyllum species by its dense gills and small pores, and the upper surface usually much smoother and softer than in other species - cystidia are normally more thin-walled than in Gloeophyllum saepiarium, (Gilbertson). Gloeophyllum sepiarium has 1.5-2 gills per millimeter at the cap margin while Gloeophyllum trabeum has 2-4 pores/gills per millimeter, (Breitenbach).

annual or perennial, most common on hardwood trees, but also noted on conifer wood especially structural timbers, causes a brown rot, one of the most important causes of decay in houses and other wood structures in North America, (Gilbertson), single to gregarious on dead barkless wood of hardwoods and conifers, commonly on construction wood in sunny places, (Breitenbach), probably all year, (Buczacki)
