, part above host tissue heavily pigmented covered by clypeus tissues (Fig. 25b). Hamathecium of dense, long, cellular pseudoparaphyses, 1.5–3 μm broad, rarely septate, embedded in mucilage. Asci 150–200 × 15–25(−33) μm (\( \barx = 181 \times 20.6\mu m \), n = 10), (2-)4-spored, bitunicate, fissitunicate, broadly cylindrical, with a short, thick, furcate pedicel which is 20–40 μm

long, no apical apparatus observed (Fig. 25e). CH5424802 ascospores 37–45 × 12–17 μm (\( \barx = 43 \times 15\mu m \), n = 10), uniseriate and sometimes slightly overlapping, oblong with broadly rounded ends, dark brown, verrucose or smooth, 7–9 transverse septa and 1–3 longitudinal septa in some of the cells, no constriction at the septa (Fig. 25c and d). Anamorph: none reported.

Notes Morphology Decaisnella was formally established by Fabre (1879), but was treated as a synonym of Teichospora by Saccardo (1883). This was followed by several mycologists over a long time. The main morphological differences between Decaisnella and Teichospora include the size and septation of ascospores, shape of ascomata, structure of peridium and type of pseudoparaphyses (Barr 1986). Thus Barr (1986)

revived Decaisnella and assigned it to Massariaceae based on the shape of ascomata and large, distoseptate ascospores. Currently, 15 species are accepted under Decaisnella (http://​www.​mycobank.​org/​MycoTaxo.​aspx). Neither the size of ascomata nor the ascospore characters have proven sufficient to place taxa at the family level in Pleosporales (Zhang et al. 2009a), and therefore familial placement of Decaisnella remains uncertain. Phylogenetic study Decaisnella formosa resided in the clade of Lophiostomataceae and in proximity to Lophiostoma macrostomoides De Not. (Plate 1). Concluding remarks The muriform ascospores, saprobic life style and 4-spored asci point Decaisnella spectabilis to Montagnulaceae, but this can only be confirmed following a molecular phylogenetic study.

Auersw., Hedwigia 5: 49 (1866). Calpain (Delitschiaceae) Generic description Habitat terrestrial, saprobic (coprophilous). Ascomata medium- to large-sized, solitary or scattered, immersed to erumpent, globose or subglobose, apex with or without papilla, ostiolate. Peridium thin, composed of compressed cells. Hamathecium of dense, long pseudoparaphyses, anastomosing and branching. Asci 8-spored, cylindrical to cylindro-clavate, with short pedicel. Ascospores uni- to triseriate, pale to dark brown, ellipsoid, 1-septate, usually constricted at the septum, smooth, with a full length germ slit in each cell. Anamorphs reported for genus: none.
