sp. nov., the Fynbos morel-the first description of an endemic species from Africa.

A species of was observed growing in spring, under a vulnerable member of the , in the Cape Floristic Region of South Africa. These fungi shared many of the cryptic characteristics common in the genus and displayed a wide range of phenotypic expression. The unique ecology of these fungi and the fact that no endemic species have been described from Africa lead to suspicions that this could be a novel species.

20 years of bibliometric data illustrates a lack of concordance between journal impact factor and fungal species discovery in systematic mycology.

Journal impact factors were devised to qualify and compare university library holdings but are frequently repurposed for use in ranking applications, research papers, and even individual applicants in mycology and beyond. The widely held assumption that mycological studies published in journals with high impact factors add more to systematic mycology than studies published in journals without high impact factors nevertheless lacks evidential underpinning. The present study uses the species hypothesis system of the UNITE database for molecular identification of fungi and other eukaryotes to trace the publication history and impact factor of sequences uncovering new fungal species hypotheses.

A description of two novel species from southern Africa and some notes on African traditional hallucinogenic mushroom use.

Two new species (Hymenogastraceae), and , are described from southern Africa. Morphology and phylogeny were used to separate the two novel fungi from their closest relatives in the genus. was found fruiting on bovine manure-enriched grasslands in the Kwa-Zulu Natal Province of South Africa and differs from its closest relative and others in the internal transcribed spacer ITS1-5.

Size based dependence of patient dose metrics, and image quality metrics for clinical indicator-based imaging protocols in abdominal CT procedures.

Introduction: Diagnostic reference level (DRL) values for computed tomography (CT) based on clinical indication are warranted since imaging protocols are indication-dependent. This study proposes clinical DRL values using the CT dose metrics and five patient size-related parameters while considering image quality.

Methods: The volumetric CT dose index (CTDI), dose-length product (DLP) and five size-related parameters of size-specific dose estimates (SSDE), namely the anterior-posterior (AP) dimension, lateral (LAT) dimension, sum dimension, effective diameter, and the body mass index (BMI), were used to calculate DRL values for CT chest-abdomen-pelvis (CAP) and abdomen-pelvis (AbP) protocols.

Hericium ophelieae sp. nov., a novel species of Hericium (Basidiomycota: Russulales, Hericiaceae) from the Southern Afrotemperate forests of South Africa.

A novel species of was recently collected in the Afrotemperate forests (Knysna - Amatole region) of Southern Africa. The novel species shares many similar, dentate features common to other species in , and its basidiome first appears stark white and yellows with age. However, the substrate choice and gloeocystidia and basidiospore sizes of the specimens collected were distinct from other species.
