Description:Clavariadelphus ligula (L.: Fr.) Donk
Macromorphology (n = 5): PDA: Radius at week III 14-18 mm, week VI 28-32 mm; mat thin, appressed, tightly interwoven, initially chamois-like, in time farinaceous to subfelty, not translucent, initially white to pallid, finally yellowish white (3A2, 4A2) to cream (4A3); margin 3-5 mm broad, thin, submerged, uneven, semi-translucent, initially white to pallid, finally yellowish white (3A2, 4A2); Plug soon farinaceous to subfelty, concolorous with mat. MMN: Radius at week III 18-24 mm, week VI 30-38 mm; mat thin, appressed, tightly interwoven, initially chamois-like, in time farinaceous to subfelty, not translucent, initially white to pallid, finally yellowish white (3A2); margin 7-10 mm broad, submerged, thin, uneven, semi-translucent, white to pallid; Plug soon farinaceous to subfelty, concolorous with mat. MEA: Radius at week III 20-25 mm, week VI 55-65 mm; mat thin, appressed, tightly interwoven, initially chamois-like, in time farinaceous to subfelty, not translucent, white to pallid; margin 3-5 mm broad, thin, submerged, uneven, semi-transparent, concolorous with mat; Plug soon farinaceous to subfelty, concolorous with mat. Extracellular Oxidase Reactions: Gallic and tannic acid agar and L-tyrosine negative. Some isolates were weakly positive for gum guaiac while others were negative. Syringaldazine positive.
Micromorphology (n = 5): PDA: Hyphae mostly undifferentiated with scattered, irregular, coralloid to subcoralloid branches, clamped, uninflated or irregularly inflated (- 10 µm); walls thin or irregularly thickened to 1 µm, smooth or encrusted with irregularly angular-shaped crystals; clamps uninflated or inflated (-8 µm), sometimes medallion or ampulliform; vesicles few to many, intercalary or terminal. MMN: Hyphae as in PDA; vesicles as in PDA. MEA: Hvphae as in PDA; vesicles as in PDA.
