H. hevese Fetch, is on Para rubber; H. these Bernard on tea in India; H. iberidis Poll, on Iberis and H. lunaiise Poll, on Lunaria, both in Italy. Spondylocladium Martius (p. 609) Hyphse creeping, septate; conidiophores erect, simple, ri^d; conidia verticillate, fusoid, usually 3-celled, brownish. A small genus. S. atrovirens Harz.** Conidiophores solitary or clustered, cylindric, septate, dingy, olive or brownish, up to 400 /* high; conidia elongate, ovate, apex narrowed, 5 to 7-septate, concolorous with the conid- iophores, 30-50 X 6-9 II. On potatoes this fimgus causes blackish to olive spots soon depressed, 2-3 cm. across, which are beset with small black sclerotia and followed by dry rot. According to Appel & Laubert '^^ the sclerotia develop whorls of conidiophores. The species is ^atroVfrrnl' said to occur in the British Isles, the Continent After Maasee. and in ;* Its sterile mycelium has been described under the name Phellomyces.*^*.
