Academic literature on the topic 'Pseudobaeospora'

Based on molecular and morphological evidence the new subfamily <i>Pseudobaeosporoideae</i> of the <i>Tricholomataceae</i> is established within the <i>Tricholomatineae</i> for accommodating the unique features of <i>Pseudobaeospora</i> such as gymnocarpic mycenoid/collybioid habit, small-sized spores with thick and dextrinoid wall, and presence of crassobasidia. Twenty-six <i>Pseudobaeospora</i> collections corresponding to eleven species (five types) were newly sequenced. Collections morphologically attributable to <i>P. oligophylla</i> (type of the genus) or to <i>P. pillodii</i> are here sequenced for the first time: accordingly, <i>P. oligophylla</i> is considered as a posterior synonym of <i>P. pillodii</i>. Quélet's original plate is selected as a lectotype for <i>Collybia pillodii</i> and a French collection as its epitype collection. <i>Pseudobaeospora deceptiva</i> is described as a new species from Italy very close to <i>P. pillodii</i> from which it differs mainly by bigger spores and SSU and LSU rDNA sequences. The presence of <i>P. pyrifera</i> in Italy is documented for the first time and <i>P. mutabilis</i> is reduced to its later synonym. A neotype is established for <i>P. jamonii</i> which is here proved to be an independent species. Finally, a critical review of the characters used for interspecific distinctions in <i>Pseudobaeospora</i> was provided.

Pseudobaeospora cyanea, a rare basidiomycete belonging to an underinvestigated genus, is currently recorded from only three localities of the Iberian Peninsula. Moreover, to date no sequences of this rare species have been deposited in GenBank. In this paper a new collection from NW Italy is reported with detailed morphological descriptions and iconography. The first ITS and LSU sequences for the species are provided and uploaded to GenBank, and the taxonomic placement of P. cyanea within the genus is discussed.
