. Bulletin of the British Museum (Natural History) Botany. 200 D. L. HAWKSWORTH. 10/im Fig. 4 Ampullifera foliicola (IM1 55448^—holotype). hyphae relatively thin-walled, smooth-walled, pale brown to brown, septate, not or slightly constricted at the septa, cells very variable in length, mainly 7-12 um long and 3-4-5 urn wide; hyphopodia abundant, alternate or opposite, generally arising towards the distal end of the cell, usually only one per cell but exceptionally more, subglobose below, base mainly 2-5—4 fira diam, paler than the hyphae on which they arise, distinctly mucronate, the neck straight to flexuose and to 7x0-5 um. Conidiophores macronematous, mononematous, erect, mainly unbranched but exceptionally with subpenicillate heads, thick-walled, smooth-walled, dark brown, septate, becoming constricted above at the septa, 30^0 um tall and mainly 5-6 um wide, the foot-cell rounded and somewhat swollen (to 7 um wide) but not lobed. Conidiogenous cells monoblastic, not differentiated from the conidiophores and each apical cell in turn acting as a conidiogenous cell. Conidia arising in single acropetal chains, often adhering in chains after separation from the conidiophore, dry, non-septate, brown, slightly paler than the conidiophores, smooth-walled, ellipsoid, gradually truncated at the apices, (6-)7-13(-15)x4-6 ^m, scar 1-2 um diam. Hosts: In the original collection the fungus occurs on the thallus of a sterile Tricharia species, while in the material from Brazil it grows over thalli also infected with Pyrenotrichum splitgerberi Mont. (syn. Chlorocyphella aeruginascens (Karst.) Keissl.) which most probably belong to a species of either Lopadium or Tapellaria to judge from the host range of that fungus (see Santesson, 1952:40)..
