Description:Fomitella supina (Sw.: Fr.) Murr. Fig. 3rd Bull. Toney Bat. Club, 32: 365. 1905.
Cultures studied: cc 549 (= FLOR 11095; BRAZIL, SC, Ilho de Santa Catarina, Morro da Lagoa; Degenhardt, Halmenschlager & Neves; 22/IX/1994); cc 663 (a FLOR 11213; BRAZIL, SC, Ilho de Santa Catarina, Morro da Logoa; Althoff, Gerber & Foresti; 30N/1995).
Macroscopic characters: Mat cottony and white, becoming crustose and pale brown after the 3th week; margin regular; growing rapidly, dish txlvered by the 2th week. Reverse unchanged. Odor sweet.
Microscopic characters: Mycelium formed by generative clamped hyphae (3,0 - 6,0 µm diam.) thin and thick walled. Fiber hyphae thick walled (3,0 - 5,0 µm diam.) in the center of the colony and, after the 3th week, also in the margin. Sexual structures absent.
Enzymatic tests: GAA: +++; TAA: ++++; Laccase: +++(a-naphtol), -(guaiacol), +++(syringaldazine); Cytochromo oxidase: +++(tmpda); Peroxidase: +++(pyrogallol); Tyrosinase: -(p-cresol)
Species code: 2. 3. 8. 32. 36. 38. 50. 54.
Remarks: Fomitella supina is the only species in thls genus and it is morphologically similar with species of Fomltopsis. In fact, the character that distinguishes them is the type of rot (Gilbertson & Ryvarden, 1986), which in culture is seen as positive reaction in the enzymatic tests (GAA, TAA) for Fomitella. Cultures of some Fomitopsis species studied by Stalpers (1978) are very similar to our culture of Fomitella supina. Generally, Fomitopsis species produce chlamydospores in culture, but our cultures of Fomitella supina did not, thus this structure may be another character to distinguish these species, besides the type of rot.
