 Add this item to the list   PHLEBIA RADIATA Fr.
Page number:258 
Remarks (public):Phlebia radiata is associated with a white rot (Lindsey & Gilbertson 1978; Ginns 1976) of angiospermous and, occasionally, of gymnospermous logs and slash throughout North America (Cooke 1956; Conners 1967; Gilbertson & a1. 1974; Ginns 1976, 1986a). Phlebia radiata is often isolated from decay in wood products and may be present as dikaryons or monokaryons (Zabel & a1. 1980, 1985; Eslyn & Lombard 1983). Although similar to P. rufa in culture (Table 13), P. radiata develops persistent, conspicuous, thick walled (>2 µm thick) marginal hyphae. Phlebia rufa also produces some thick walled (>1.5 µm thick), simple-septate, marginal hyphae, but these are not conspicuous.  
Description type:Culture description 
Mats white, most isolates around inocula thin to moderately thin, slightly raised to raised, subtomentose, then becoming thinner, appressed, and subfelty toward margins, a few isolates thin, appressed, and subfelty throughout, other isolates thin, slightly raised, and arachnoid throughout at 1 wk, by 2 wk similar except often becoming sodden and appressed around inocula or sodden areas scattered throughout mats, by 6 wk white to Pale Pinkish Buff, thin to moderately thick, slightly raised to raised, felty to tomentose, with mycelia growing up dish sides, fertile areas when present Pinkish Buff to Cinnamon Buff, tuberculate, developed in small clusters at mat periphery or scattered throughout mats; margins even, appressed; odor absent or sweet-sour at 2 and 6 wk; agar partially or entirely bleached at 2 wk, bleached by 6 wk; sometimes fruiting by 6 wk. ; TAA mats at 2 wk white, moderately thick, raised, cottony to woolly, then becoming thinner, appressed, and subfelty toward margins.
MEA (82-)90+; 90+; GAA +++ to ++++, (0-)23-50; (0-)42-90

microscopic characters: Marginal hyphae 4-8 µm diam, thin walled to slightly thick walled at first but becoming thick walled by 2 wk (Fig. 62c), simple septate, sparsely to moderately branched. Submerged hyphae (a) similar to marginal hyphae and persisting in old cultures; (b) 1.5-5 µm diam, thin walled to slightly thick walled, nodose septate, moderately branched Surface and aerial hyphae 2-6 µm diam, thin walled to slightly thick walled, occasionally becoming thick walled or rough walled (Fig. 62d), nodose septate, sparsely to moderately branched, with segments moderately encrusted with crystalline materials or coated with a thin layer of resinous materials that were dislodged but did not appear with 2% KOH. Cystidia (Fig. 62a) spathulate to clavate or obclavate to fusiform, 16-80 x 6-9 µm, thin walled to slightly thick walled, terminal, clamped at basal septum, smooth or coated with resinous materials, abundant in aerial mats at 2 and 6 wk. Arthroconidia (Fig. 62b) cylindrical to doliform, 2-20 x 2-4 µm, hyaline, thin walled, rarely branched, scattered or absent in aerial mats at 2 wk, absent at 6 wk. Monosporous cultures: Six isolates of JLL 15608, with each mating type represented, were studied. These cultures were similar to the dikaryon cultures except that they lacked clamp connections, developed abundant arthroconidia, and did not develop fertile areas.
