Acanthophiobolus helicosporus (Berk, & Br.) Walker: On dead overwintered stems of Equisetum sp. (developed in moist chamber). Arachnoid (cobweb-like) colony. Ascomata develop on superficial mycelium and on substrate surface, globose (200µm dia) with short papillate neck, pale brown peridium (text. Angularis), spines around ostiole dark brown and septate, up to 200µm long, short spines around 30 µm long also present; paraphyses not observed; asci 170-250×10µm; spores hyaline, filiform up to 160×2µm, multiseptate? (difficult to determine), slightly swollen pale area (empty cell??) at apex, helically coiled in the ascus. Reference – Walker, J. 1980. Gaeumannomyces , Linocarpon, Ophiobolus and several other genera of scolicospored Ascomycetes and Phialophora condial states, with a note on hyphopodia. Mycotaxon 11: 1-129.

Allophylaria subliciformis Karsten: On dead influorescence of Cirsium sp. Ascomata glassy looking (shiny), text. lineolata/porrecta (hyphal like), pale cream to white; filiform paraphyses; asci 170×12-15µm I+ (redder) in Lugols; spores 25-30×6.5-7.5µm, often 3-septate when germinating.
