New records and geographic distribution map of Echinoporia Ryvarden (Schizoporaceae, Basidiomycota) species in the Neotropics

The genus Echinoporia is characterized by the presence of chlamydospores originating from hairs in the pileus and margin, or the dissepiment edges. Two species of Echinoporia are found in America, i.e., E. aculeifera and E. inermis. In a study of Neotropical polypores, several specimens of Echinoporia were collected in the Atlantic rainforest, São Paulo state. Echinoporia inermis is recorded for the second time in Brazil. Echinoporia aculeifera is recorded for the first time in São Paulo state. A distribution map of the genus in the Neotropics is presented

Revision of Protohydnum (Auriculariales, Basidiomycota)

Three species currently addressed to Protohydnum (Auriculariales) are studied with morphological and DNA methods. The genus Protohydnum is retained for the type species only, P. cartilagineum, recently re-collected in Brazil. The European species, P. piceicola, is not congeneric with P. cartilagineum and, therefore, placed in its own genus, Hyalodon, gen. nov. Another Hyalodon species, H. antui, is described from East Asia. The third member of Protohydnum sensu lato, P. sclerodontium from South-East Asia, is transferred to Elmerina.Peer reviewe

What Do the First 597 Global Fungal Red List Assessments Tell Us about the Threat Status of Fungi?

Fungal species are not immune to the threats facing animals and plants and are thus also prone to extinction. Yet, until 2015, fungi were nearly absent on the IUCN Red List. Recent efforts to identify fungal species under threat have significantly increased the number of published fungal assessments. The 597 species of fungi published in the 2022-1 IUCN Red List update (21 July 2022) are the basis for the first global review of the extinction risk of fungi and the threats they face. Nearly 50% of the assessed species are threatened, with 10% NT and 9% DD. For regions with a larger number of assessments (i.e., Europe, North America, and South America), subanalyses are provided. Data for lichenized and nonlichenized fungi are also summarized separately. Habitat loss/degradation followed by climate change, invasive species, and pollution are the primary identified threats. Bias in the data is discussed along with knowledge gaps. Suggested actions to address these gaps are provided along with a discussion of the use of assessments to facilitate on-the-ground conservation efforts. A research agenda for conservation mycology to assist in the assessment process and implementation of effective species/habitat management is presented

O Estágio de Docência na formação dos pós-graduandos do Instituto de Botânica, SP, Brasil

RESUMO O Estágio de Docência (ED) é entendido como um componente curricular promotor da inter-relação entre teoria e prática pedagógica, capaz de aproximar o pós-graduando das atividades de ensino. Nesse contexto, os objetivos desse estudo foram: 1) avaliar a percepção dos discentes sobre as contribuições do ED desenvolvido pelo Programa de Pós-graduação em Biodiversidade Vegetal e Meio Ambiente do Instituto de Botânica (PPGIBt) para o exercício da docência no ensino superior; 2) investigar a percepção dos docentes do PPGIBt sobre a importância dos componentes relacionados à prática pedagógica na formação dos pós-graduandos. Questionários eletrônicos foram respondidos por 21 discentes (matriculados no ED entre 2010-2015) e 18 docentes do PPGIBt. Embora os grupos investigados citem que o PPGIBt valoriza a pesquisa em relação ao ensino da prática docente, existe o reconhecimento da importância do componente docência para a formação e atuação profissional no ensino de nível superior. Embora solicitações e sugestões de aprimoramento do ED no PPGIBt tenham sido levantadas, em termos gerais, esse modelo parece ser produtivo para a construção coletiva da prática docente no ensino superior e tem suscitado reflexões sobre a futura atuação profissional e a contribuição social da pesquisa que cada discente desenvolve
