A NEW SPECIES OF PENICILLIUM
青霉属的一个新种

A new species, Penicillium resinae sp. nov., is reported in this paper. Colonies on Czapek's agar growing very restrictedly, with central area raised, showing aerial ropes of hyphae; conidial area in dark olive shades; colony margins irregular, charaterized by the presence of stolonlike aerial hyphae which re-entered the substratum beyond the limits of the submerged vegetative mycelium; reverse uncolored; penicilli biverticillate and symmetrical but with monoverticillate structures and additional branches occurred; conidiophores arising mainly at right angles from funiculose hyphae, often very short; metulae compactly arranged; phialides not characteristically lanceolate but somewhat tapered abruptly to narrow-conidium bearing tubes; conidia globose to subglobose, tuberculate; conidial chains in short columns with tips somewhat pyramidal or divergent. This species, on account of the structure of the penicilli and the texture of its colonies, is to be classified in the Penicillium funiculosum series, Bivertieillata-Symmatrica, near Penicillium piceum Raper et Fennell. However, it differs markedly from the latter in rate of growth and in the characters of its conidia as well as in the presence of stolon-like aerial hyphae. Moreover, it was found to be sufficiently different from other species of the genus described so far. Therefore, it is described and proposed as a new species. The fungus was isolated from the resins of Euclayptus tereticornis Smith and hence the specific epithet. The type specimen HMAS 42799 as well as living culture AS 3.4387 have been deposited in the Institute of Microbiology, Academia Sinica, Beijing, China.
