Through rigorous morphological comparisons and molecular phylogenetic analyses, we have identified two new species (<i>N. guangxiensis</i> and <i>N. pubeiensis</i>) and two new host-recorded species (<i>N. oryzae</i> and <i>N. camelliae-sinensis</i>). The morphological analysis revealed that the new species align with the genus-level definition of <i>Nigrospora</i> in colony morphology, conidiophores, and conidial characteristics. However, they were distinguished from known species by finer features such as conidial dimensions and conidiogenous structures. For instance, conidiophores in <i>Nigrospora</i> are typically differentiated from hyphae, characterized by dark pigmentation, which is consistent with broader taxonomic descriptions. Molecular phylogeny, based on concatenated datasets of the ITS, <i>TEF1-α</i>, and <i>TUB2</i> loci, showed that <i>N. pubeiensis</i> is most closely related to <i>N. chinensis</i>, while <i>N. guangxiensis</i> forms a distinct basal clade relative to these two groups.

The study enriches the taxonomic framework of <i>Nigrospora</i> by providing novel data from China, emphasizing the importance of integrating morphological and molecular approaches in fungal systematics. It also underscores the ecological diversity of fungal-host interactions in agarwood-producing trees, a topic explored in related research on endophytic fungi.

All four sorediate <i>Cetrelia</i> species are morphologically very similar and also show a similar ecology. They can be identified by chemical characters related to their distinctive secondary metabolites, whose diagnostic value is also supported by molecular data. In addition, they are overall rare, and therefore virtually endangered, although in previous assessments they were evaluated as \"data deficient\" due to the scarcity of available data. The few, old literature records in Italy refer almost exclusively to one species (<i>C.olivetorum</i>), which, however, has been shown to be quite rare in other European countries. To better elucidate the actual distribution of the four species in Italy, we carried out a revision of all the available herbarium specimens and checked several new collections from the main centres of distribution. We analysed 320 specimens from 59 sites, confirming the occurrence of all the four species reported from Europe. <i>Cetreliamonachorum</i> is the most widespread, ranging from the Alps to the Apennines and Sardegna. <i>Cetreliacetrarioides</i> is less widespread, occurring across the Italian Alps. <i>Cetreliaolivetorum</i> is confined to the Eastern Alps and northern Apennines. <i>Cetreliachicitae</i> is the rarest, being found only in five sites in the Central and Eastern Alps.
