Description : Ganoderma brownii (Murrill) Gilb., Mycologia 53: 505 (1962 [“1961”]). Fig. 1

Basidiomata 6.5-16 × 6.5-15 × 1.4-2 cm, perennial, sessile, occasionally imbricate, woody. Pileus round-flabelliform to circular, generally applanate; surface glabrous, bumpy, dull, concentrically sulcate; with a 0.6-0.8 mm thick crust, not cracking, very hard, difficult to penetrate with the fingernail; surface brown (7F7); margin concolorous, entire, thin to thick, obtuse, sulcate. Context 0.3-0.9 cm thick, fibrous, homogeneous, reddish-brown (9F8), azonate; generally with resinous deposits close to the pileus’ base. Pores 4-5 per mm, angular to round, woody; pore surface yellow (3A2) to chromeyellow (2A8); tubes 0.4-1.5 cm thick, unstratified to stratified, concolorous with the lower part of the context. Hyphal system trimitic. Contextual trama: no generative hyphae were observed; skeletal hyphae 3.7-9.3 µm diam., generally solid to thick-walled, non-septate, arboriform, yellowishbrown; no binding hyphae were observed. Pileipellis a crustotrichoderm; terminal elements 6.8-9.3 µm wide, with apex 7-10 µm wide, entire, solid, golden-yellow. Basidiospores 9.3-11.2 × 6.6-7.4 µm, Q = 1.25-1.5, widely ellipsoid to ellipsoid, apex truncate, yellowish-brown, inamyloid; perisporium wrinkled, reddish-brown; exosporium with inter-walled pillars 0.5-0.8 µm thick, anastomosed. Basidia not observed. Cystidia absent.
Habitat: Atlantic dense ombrophilous rain forest.

Remarks (public) : Ganoderma brownii is distinguished from G. applanatum by its yellow pore surface and larger basidiospores.

Description : Ganoderma brownii (Murr.) Gilbn. Fig. 139
Mycologia 53:505. – 1962. Elfvingia brownii Murr., West. Polyp., p. 24. 1915.
Basidiocarps perennial, sessile, dimidiate, applanate to ungulate, up to 20 × 10 × 5 cm; pileus surface finely tomentose and yellowish at the growing margin, quickly becoming crustose with a hard, horny crust up to 1 mm thick, pale vinaceous to grayish brown, shallowly to deeply sulcate and faintly zonate; pore surface with a bright yellowish cast, bruising dark brown, the yellowish cast remaining on dried specimens, the pores 4-5 per mm, rounded, with very thick, entire dissepiments; context dark purplish brown, firm-fibrous, concentrically zonate, up to 4 cm thick; tube layer purplish brown, sharply differentiated from the context, tubes whitish within, up to 1.5 cm thick.
Hyphal system trimitic; contextual generative hyphae obscure, thin-walled, hyaline, with clamps, 2.5-3.5 µm in diam; contextual skeletal hyphae thick-walled, pale brown in KOH, nonseptate, with occasional branching, 2-10 µm in diam; contextual binding hyphae rare to apparently absent in crushed mounts of context tissue; tramal generative and skeletal hyphae similar; tramal binding hyphae hyaline to pale brown, thick-walled, nonseptate, much branched, 2-5.5 µm in diam, often dendritically branched with tapering, pointed tips.
Cystidia or other sterile hymenial elements absent.
Basidia collapsed and difficult to discern in type specimen, apparently broadly clavate with a sharply narrowed base, 4-sterigmate, about 23×11 µm. Basidiospores broadly ellipsoid, with a truncate apex and an apical germ pore, brown in KOH, negative in Melzer’s reagent, wall two-layered with interwall pillars, 11-12 × 7-8 µm.
Type of rot – White rot of living and dead hardwoods.
Cultural characteristics – Unknown.
Sexuality – Unknown.
Substrata – Known on Umbellularia, Hakea, Quercus, and Schinus. Distribution – Known only from California.

2. ELFVINGIA BROWNII Murrill, sp. nov.
Pileus encrusted, very hard, dimidiate, applanate, broadly
attached, subimbricate, 8-10 X 15-25 X 3-4 em.; surface gray
to brown, glabrous, concentrically sulcate, rather uneven, margin
very obtuse, broadly sterile, luteous, subentire; context almost
woody, zonate, bay, about 3 cm. thick, thinner with age; tubes
5-8 mm. long each season, avellaneous to dark-umbrinous within,
mouths minute, circular, about 5 to a mm., luteous-stuffed when
young, edges obtuse, entire; spores broadly ellipsoid, slightly
roughened, brown, uniguttulate, truncate at one end, thickwalled,
8-<) X 7 11-.
Type collected on decaying log~ of Umbellularia in Strawberry
Cany:on, University of California campus, Berkeley, California,
September 27, 1913, V. S. Brown 307 (herb. N. Y. Bot. Gard.).
Also collected in a younger stage at the same place on the same
host, September 12, 1913, V. S. Brown 306. This species resembles
E. megaloma in habit and appearance, but the hymenium
is luteous instead of white when young.
