The authors discuss and illustrate several American collections of Cantharellus that are in one way or another related to species that have previously been reported or described from Wisconsin. These new collections indicate that the potential distribution area of many of these chanterelles may be much larger than generally assumed. Cantharellus deceptivus sp. nov. is described as new cryptic look-alike of C. phasmatis and problems related to the narrow species concept of C. flavus and C. phasmatis are discussed; C. iuventateviridis sp. nov. is described as closest southern relative to C. chicagoensis. Microscopic features of C. chicagoensis and C. flavus are illustrated for the first time. Cantharellus spectaculus is considered a later synonym of C. persicinus on morphological criteria.

Purpose - The purpose of this paper is to identify energy efficiency metrics that can be used by IT managers to measure and maintain the implementation of cost savings and green initiatives in data centers. Design/methodology/approach - The paper looks at the background of the problem and explores the reasons why energy savings in the data center are an important issue. Included are interviews and survey results from IT professionals serving at four unique organizations. A model of the measurable components of a data center is created to provide a framework for organizing metrics and communicating results throughout the corporation. The strengths and weaknesses of two of the most common data center metrics, PUE and DCP, are examined closely. Findings - The paper concludes with future metric, recommendations and a proposed credit-based system that could be applied to encourage closer management of these metrics. Practical implications - The metric recommendations can be used by IT managers resulting in energy efficiency improvements in their data centers. Originality/value - The paper provides a good comprehension of multiple approaches and makes recommendations for a platform metric that can be further developed and adopted as a standard.
