Abstract

1. After discussing the outer characters of the three genera Auricularia Bull,ex Merat, Hirneola Fr. (1848), and Laschia Fr., now often combined into a single genus, the author concludes that there is every reason to follow Bresadola and to keep Auricularia and Hirneola apart as distinct genera, and to enter Laschia into Hirneola. 2. It is pointed out that in Hirneola the hymenophore is not invariably inferior. 3. The author once more discusses the desirability of conserving the name Hirneola Fr. 1848. He withdraws his previous proposal for conservation of Auricularia Bull, ex Brongn. 1824. 4. The new combination Hirneola nigricans (Sw. ex Fr.) Donk is proposed. 5. It is possible that the correct name for the Judas' ear is Hirneola auricula(L. ex Mexat) H. Karst.

Abstract

1. The present paper is the first of a series intended to deal from a nomen clatural point of view with all the generic names proposed for Hymenomycetes.For each name the following items are considered: (i) its etymology and gender, (ii) the original scope of the corresponding genus, and, in case of the name being- an isonym,also of the group covered by its basinym; (iii) the type species, which when not originally designated, is selected; (iv) its basinym, synisonyms,homonyms, typonyms,and variant spellings, if any, are indicated; (v) its status under the Rules is determined;and (vi) supplementary remarks are given when these are deemed useful. 2. This first instalment deals with "Cyphellaceae," a group defined in a conventional, rather descriptive, manner, not as a taxonomic unit. 3. A new generic name, Stromatoscypha Donk, is introduced for Porothelium(Pr. ex Fr.) Fr. 4. The following new combinations are made: Aleurodiscus digitalis (A. & S.ex Fr.) Donk [basinym: Cyphella digitalis (A. & S.) ex Fr.], and Stromatoscypha fimbriata (Pers. ex Fr.) Donk [basinym: Polyporus fimbriatus (Pers.) ex Fr.].

Abstract

When the type method was introduced in the "International Rules of Botanical Nomenclature," it was stated that "a nomenclatural type is that constituent element to which the name of a group is permanently attached" and, further, that "the type of ..a generic name is a species and that of a species ..is usually a specimen or preparation. In some species, however, the type is a description or figure given by a previous 1 author" (Art. 18).No doubt, the type of a generic name is a species and that of a specific name a specimen (or its substitute). A species may be variously interpreted as to its limits; it may be narrowly or broadly conceived. It may receive a name, but it remains a species even if it has no name. It frequently occurs that a specific name is misapplied to a quite different species. Hence it is also evident that a species and a specific name are two intrinsically different notions, not at all identical and interchangeable. As quoted above, Art. 18 positively says that the type of a generic name is a species and does not refer to specific names. I believe this article really states what it wanted to convey in this respect, and is not an instance of unfortunate wording. A species comprises a vast number of 'individuals plants' and of these some are preserved often only in part, or are subject to taxonomic study without preservation,and represent the 'specimens' of the Rules; when the species is given a name, one of these is or afterwards becomes the 'type specimen.' Thus a (type) species and a (type) specimen are different notions. In the binomial system a specific name is a combination of two words. The first part, or generic appellation, stands for a generic description,2 the second part, or specific epithet, for a specific description : a specific name roots in two different descriptions.Far more often than not these two are published on different occasions by different authors.
