Its Sequences

Species of Tricholoma sections Genuina and Megatricholoma are characterized by having pilei that are some shade of brown, and by white or yellow lamellae that also discolor some shade of brown. From Costa Rica in sect. Genuina, we describe as new T. luteopallidum, T. cacumense, and T. talamancense, and confirm the occurrence of Tricholoma stans, and from the United States describe as new Tricholoma brunneoluteum. Tricholoma roseoacerbum from sect. Megatricholoma is con-firmed for Costa Rica. Morphology as well as ITS sequences are employed to confirm the species’ identifications or circumscription of the new species.

Three New Species

Three new species of Tricholoma are described from Costa Rican montane forests with additional collections cited from the United States. The new species are Tricholoma felschii sp. nov., Tricholoma costaricense sp. nov. and Tricholoma atratum sp. nov. A discussion of Tricholoma luteomaculosum is also included. These taxa share morphological features of strong farinaceous odor and taste, pseudoparenchymatous pileal subcutis, and rugulose pileus at some stage of development. In addition, cheilocystidia occur in two of the taxa but not the third. Phylogenies are presented based on ITS sequences.

The genus Ochterus is revised for Mesoamerica and the continental United States. The fauna as currently understood contains ten previously described species, and the following ten new species described herein: O. chiapensis from southeastern Mexico, O. costaricensis from Costa Rica, Panama and El Salvador, O. explanatus from western Mexico, O. mexicanus from central Mexico, O. obscurus from Costa Rica, O. ovatus from southeastern Mexico, O. panamensis from Panama, O. pseudorotundus from northeastern Mexico, O. shepardi from Costa Rica, and O. smaragdinus from southeastern Mexico. Ochterus flaviclavus Barber is shown to represent an intraspecific color morph of O. banksi Barber and is synonymized under the latter species. Color photographs of the dorsal body and frons, as well as line drawings of male genitalic structures, are provided for all species treated, accompanied by distribution maps.

A New Species

The name Agrilus impexus Horn has been found to belong to a Great Plains species and to be misapplied to a common southwestern Agrilus. Agrilus impexus is redescribed and A. paraimpexus, new species, is described from New Mexico, Arizona and California to Costa Rica. It is distinguished from both Agrilus impexus and the closely related A. addendus Crotch from Texas to Vera Cruz, México, and a lectotype is designated for A. addendus. Agrilus frisoni Fisher is synonymized with A. addendus, new synonymy. Agrilus funestus Chevrolat is recorded from the United States for the first time and figured.

A New Species

AbstractThe order Intejocerida is an enigmatic, short-lived cephalopod taxon known previously only from Early–Middle Ordovician beds of Siberia and the United States. Here we report a new genus, Cabaneroceras, and a new species, C. aznari, from Middle Ordovician strata of central Spain. This finding widens the paleogeographic range of the order toward high-paleolatitudinal areas of peri-Gondwana. A curved conch, characteristic for the new genus, was previously unknown from members of the Intejocerida.UUID: http://zoobank.org/21f0a09c-5265-4d29-824b-6b105d36b791

Generic Description

Podosordaria Ellis et Holw. is used for those members of the Xylariaceae possessing stalkedor sessile stromata in the form of mammillate heads with erumpent ascocarps, containing whitish internal tissue, and covered with a brown to black or violaceous ectostroma; cylindrical to pyriform asci in which the ascospores may be biseriately arranged posteriorly; and one-celled, dark brown spores possessing elongated germ slits. The classical separation between Poronia Willd. ex Fr. and Podosordaria is maintained. An emended generic description and key are provided. Four new species and one new combination are described and illustrated—P. crinita on cow dung from the United States; P. ianthina on burro and goat dung from Mexico; P. phoenicea on zebra dung from Kenya; P. vinacea on burro dung from Mexico; and P. violacea (Sordaria violacea Ell. et Ev.) on cow, sheep, horse, and rabbit dung from Canada and the United States. One additional new combination, P. hircina (Poronia hircine Tai et Wei), is proposed. Brief comparative descriptions are included for those species not treated in detail. Short descriptive notes are provided for several taxa considered as doubtful representatives.
