Extensive Damage

A new species of Dermea is described. The fungus was associated with extensive damage to young Douglas fir (P seudotsuga menziesii) following severe early frosts in the Cariboo Region of British Columbia. Inoculation tests proved the fungus was capable of invading bark wounds and causing necrosis. Life history and cultural characteristics of the fungus are presented. The development of the disease is described and discussed.

A New Species

The perfect state of Chondropodium pseudotsugae White is shown to be a new species of Durandiella, for which the name D. pseudotsugae is proposed. Maximum growth in culture is obtained on corn meal agar at 15 °C. Apothecia are produced in the spring; the ascospores are forcibly discharged; pycnidia persist throughout the summer and discharge spores only when moistened. The host response of Douglas fir is the production of a "button" of persistent secondary periderm beneath the infected area.

A new species of Coccomyces is described. The life cycle and cultural characteristics are presented. The fungus is associated with various bark diseases of western hemlock (Tsuga heterophylla) in the Coastal forest of British Columbia and Washington State. Some evidence of weak parasitism was found in natural infections; artificial inoculations with the fungus were negative.

Average Adult

Material collected in Loch Tannoch was allowed to macerate in a chemical nutrient. A rich crop of Euglena gracilis as well as other infusoria resulted. Eight months later, when the Euglena had encysted, many amoebae were found at the bottom of the receptacle. They constitute a new species, here named Amoeba hugonis. An average adult specimen, when extended, measures about 104x52·2µ. The nucleus consists of a central karyosome lying in the nuclear sap, separated from the cytoplasm by a wellmarked nuclear membrane. Between the latter and the karyosome is situated an achromatic ‘collar’ with chromatin particles embedded in it. Fission is described, but a study of mitosis has been deferred. The life-history of this small amoeba is very similar to that of the large A. proteus, &c. The cycle occupies two months. Chromidia begin to appear in the cytoplasm of the early adult. They give rise to spores, out of which amoebulae hatch.

A New Species

Occella impi, a new species of sea poacher, is described from a single specimen captured in the Queen Charlotte Islands, British Columbia. Occella impi differs from other species of Occella in having spinous plates on the breast, the anus nearer the anal fin, and fewer anal rays; also, the numbers of bony body plates are distinctive. A key to the known species of Occella, based primarily on the numbers of bony body plates, is included. The size of the maxillary barbel and number of infralateral plates are shown to be characteristic of the genera Occella and Stellerina.
