Tupper Lake at public boat launch from Rt. 30, UTM Zone 18, 539840 mE, 4892100mN; 44°10″59″N, 80°31′6″W, on submerged, decorticated wood, 7 Jul. 1994, J.L. Crane & C.A. Shearer A-254-1 (ILLS 53086, holotype). Notes Morphology Isthmosporella was described as a freshwater genus typified by I. pulchra, and is characterized by globose, pseudoparenchymatous ascomata, sparse, septate pseudoparaphyses, fissitunicate asci and hyaline, cylindrical to fusoid, phragmoseptate,

isthmoid ascospores surrounded with a gelatinous sheath (Shearer and Crane 1999). Based on the morphological characters, i.e. small, globose www.selleckchem.com/products/kpt-330.html ascomata, peridium with

small pseudoparenchymatous cells and sparse pseudoparaphyses, Isthmosporella was assigned to the Phaeosphaeriaceae (Shearer and Crane 1999). The aquatic habitat of Isthmosporella, however, disagree with the Phaeosphaeriaceae. Isthmosporella seems less likely to belong to Pleosporineae. Phylogenetic study None. Concluding remarks Molecular phylogenetic studies should be conducted to explore its familial placement within Pleosporales. Kalmusia Niessl, Verh. nat. Ver. Brünn 10: 204 ( 1872). (Montagnulaceae) Generic IWR-1 concentration description Habitat terrestrial, saprobic. Ascomata small- to medium-sized,

solitary, scattered or in small groups, immersed to erumpent, globose or subglobose, often laterally flattened, coriaceous, wall black, with or without papilla. Hamathecium of dense, filliform, delicate, septate pseudoparaphyses, branching and anastomosing between and above asci, embedded in mucilage. Asci bitunicate, fissitunicate unknown, clavate, with a long, furcate pedicel. Ascospores narrowly ovoid to clavate, PI3K inhibitor pale brown, 3-septate, distoseptate. Anamorphs reported for genus: Cytoplea (Petrak and Sydow 1926). Literature: Barr 1987b, 1990a, 1992a; Lindau 1897; von Niessl 1872. Type species Kalmusia ebuli Niessl, Verh. nat. Ver.
