The ascomycetous genus Scirrhia is presently treated as a member of Dothideomycetidae, though uncertainty remains as to which family it belongs in Capnodiales, Ascomycota. Recent collections on stems of a fern, Pteridium aquilinum (Dennstaedtiaceae) in Brazil, led to the discovery of a new species of Scirrhia, described here as S. brasiliensis. Based on DNA sequence data of the nuclear ribosomal DNA (LSU), Scirrhia is revealed to represent a member of Dothideomycetes, Capnodiales, Mycosphaerellaceae. Scirrhia is the first confirmed genus in Mycosphaerellaceae to have well developed pseudoparaphyses and a prominent hypostroma in which ascomata are arranged in parallel rows. Given the extremely slow growth rate and difficulty in obtaining cultures of S. brasiliensis on various growth media, it appears that Scirrhia represents a genus of potentially obligate plant pathogens within Mycosphaerellaceae.

The article presents a study on the importance of mucin 1 (MUC1) and interstitial collagen type IV expressions in the prognosis of patients with scirrhous gastric carcinoma. It notes that the study's aim is to determine the relationship of MUC1 and collagen in the survival of carcinoma patients and the clinical significance of fibrotic mechanism. It concludes that patients with positive expression in undifferentiated adenocarcinoma of the type IV collagen can have a critical prognosis.
