 Add this item to the list  Lenzites saepiaria Wulf. ex Fries
Page number:343 
Remarks (public):In Lenzites saepiaria, the nodose-septate hyphae undergo fragmentation to form oidia. In other species having the same key pattern, oidium formation is restricted to hyphae with simple septa in those portions of the colony that have reverted to a haploid condition. This characteristic makes possible the separation of cultures of L. saepiaria from similar species.

Description:Lenzites saepiaria Wulf. ex Fries
Cultural characters: (PI. V, Fig. 12.; Pl. VI, Figs. 39 to 41).
Growth characters. Growth moderately slow to very slow, plates covered in four to seven weeks. Advancing zone somewhat bayed, appressed and hyaline in zone 1.0-2.0 mm. broad. Mat white for two to three weeks, then with patches or zones of "chamois" (2.0Y7.5/5.8), "honey yellow" (2.0Y6.7/6.2), "tawny-olive" (8.0YR4.8/5.8) (three to four weeks), to "snuff brown" (7.0YR3.9/3.5) (four to six weeks), at first slightly raised, cottony, but Boon collapsed, farinaceous, appearing patchy by reason of variations in color and amount of aerial mycelium. Reverse unchanged or somewhat darker below colored areas. Odor slightly spicy. On gallic and tannic acid agars no diffusion zones, trace of growth up to 2.5 cm. diameter on gallic acid agar, no growth or only a trace on tannic acid agar.
Hyphal characters. Advancing zone: hyphae hyaline, nodose-septate, frequently branched, 1.5-4.5 µm diameter. Aerial mycelium: (a) hyphae as in advancing zone, but soon broken up to form oidia; (b) oidia very numerous, cylindric, frequently with swollen portion, or broadly ovoid, often with fragment of clamp connection attached, 5.0-22.0 x 2.5-4.5 À¬m. Submerged mycelium: (a) hyphae as in advancing zone; (b) chlamydospores rare or apparently lacking, terminal or intercalary, thin-walled, 7.5-16.5 x 5.0-9.0 À¬m; (c) crystals platelike or needlelike.
Type of rot: brown pocket rot of coniferous or, rarely, broad-leaved trees.
