We present here the first scientific results obtained with the coronograph described by Beuzit et al. (1996, hereafter paper I), developed to be used together with the come-on-plus/adonis adaptive optics (AO) system. Two IRAS excess Main Sequence (MS) stars, namely HR 4796 and HR 2020 (β Pictoris), have been observed. No circumstellar disk is detected around HR 4796, down to 2′′ from the star. ...

A new clitocyboid genus of Agaricales, Cleistocybe, is described to accommodate the isolated evolutionary position of the new species Cleistocybe vernalis inferred by a previously published multigene phylogenetic study. Cleistocybe is distinguished from other clitocyboid lineages by a combination of morphological characters, including lamellae that become gray in age, an interwoven hymenophoral...
