This paper is the seventh in the Fungal Diversity Notes series, where 131 taxa accommodated in 28 families are mainly described from Rosa (Rosaceae) and a few other hosts. Novel fungal taxa are described in the present study, including 17 new genera, 93 new species, four combinations, a sexual record for a species and new host records for 16 species. Some are introduced as new ascomycete genera. We also introduce new species. New host records are provided for others. New combinations are noted. This study also provides some insights into the diversity of fungi on Rosa species and especially those on Rosa spines that resulted in the characterization of eight new genera, 45 new species, and nine new host records. We also collected taxa from Rosa stems and there was 31% (20/65) overlap with taxa found on stems with that on spines. Because of the limited and non-targeted sampling for comparison with collections from spines and stems of the same host and location, it is not possible to say that the fungi on spines of Rosa differ from those on stems. The study however, does illustrate how spines are interesting substrates with high fungal biodiversity. This may be because of their hard structure resulting in slow decay and hence are suitable substrates leading to fungal colonization. All data presented herein are based on morphological examination of specimens, coupled with phylogenetic sequence data to better integrate taxa into appropriate taxonomic ranks and infer their evolutionary relationships.
