A new species of Psathyrella (Psathyrellaceae, Agaricales) from Italy

Abstract

Sporophores of a new Psathyrella species have been reported for the first time as growing at the base of Cladiummariscus culms in the Botanical Garden of the University of Calabria, Rende, Cosenza, southern Italy. The fungus was initially identified as P.thujina (= P.almerensis) by means of both ecology and macro- and microscopic characteristics of the basidiomes, then referred to P.cladii-marisci sp. nov. after extraction, amplification, purification and analysis of the rDNA ITS region. We came to this conclusion after comparing our specimen with the descriptions of the taxa available in the literature for the genus Psathyrella.

Two new rare species of Candolleomyces with pale spores from China

“…In addition, these two species have highly similar ITS regions (98%). Nevertheless, some members of Candolleomyces with high ITS similarity are still treated as separate species on the basis of morphological characters ( Sicoli et al 2019a ; Büttner et al 2020 ; Wächter and Melzer 2020 ). Candolleomyces subcacao and C. cacao group together, but comprise independent lineages, in the phylogenetic tree (Fig.…”

“…al. (2019) and is characterised by the absence of pleurocystidia and the presence of large spores up to 11 μm long ( Sicoli et al 2019a ; b ). According to our phylogenetic analysis, this species is relatively closely related to C. candolleanus , C. badiophyllus and C. trinitatensis and should be moved to Candolleomyces .…”

“…According to the research of Wächter and Melzer (2020) , Candolleomyces may be more speciose than previously thought and better delimitation of species boundaries is needed. Although controversies still exist regarding some species boundaries, the number of new taxa is steadily increasing ( Melzer et al 2018 ; Sicoli et al 2019a ; Büttner et al 2020 ). This continuous discovery of new taxa with clear boundaries deepens understanding of the species in this genus.…”

Catatan Beberapa Jamur Liar yang Tumbuh di Sekitar Pemukiman Penduduk

“…Salah satu tempat yang belum banyak dilaporkan ragam jamurnya di Indonesia adalah daerah sekitaran pemukiman penduduk ataupun tempat-tempat yang bersinggungan dengan aktivitas manusia. Hingga saat ini hanya ditemukan sedikit laporan mengenai ragam dan potensi jamur di wilayah-wilayah tersebut di Indonesia (Putra et al 2018;Putra 2020a;2020b;2020c;Khastini et al 2018;2019). Pemukiman penduduk di sekitar Bojong Gede, Bogor, Jawa Barat meruapakan salah satu lokasi dengan data ragam jamur yang belum pernah dilaporkan sebelumnya.…”

“…Kelompok jamur ini merupakan organisme yang bergaya hidup saprofit dan tersebar pada berbagai tipe ekosistem alami ataupun buatan (Sicoli et al 2019). Hingga saat ini tercatat sebanyak 1059 spesies, subspesies, dan varietas dari Psathyrella di seluruh dunia (http://www.indexfungorum.org/Names/Names .asp, diakses pada 01 Agustus 2020) dan merupakan salah satu kelompok jamur yang kompleks.…”
