Fungal Diversity 401, nor did Webster & Lucas in the taxonomic and life-history study (Trans. Brit. Myc. Soc. 42, 332– 342. 1959) of this species. The specimen has most of the features described by Webster & Lucas including the presence of the conidial state Microdiplodia henningsii Staritz. I did not see vertical septa in the ascospores. Webster & Lucas note that vertical septa may be occasionally be lacking. The fungus is otherwise as they describe it although some perithecia collapse and appear cupulate.”—by R.A. Shoemaker. Phylogenetic study None. Concluding remarks The substrate of Chaetoplea sensu Barr (1990b) can be herbaceous stalks, decorticated wood or periderm, or old cotton cloth and string, which may indicate its heterogeneous nature. The ascospores seem very much like Phaeosphaeria which may be an earlier name; more details concerning the ascomatal, peridial and hamathecial structures are needed to make any conclusion. Cilioplea Munk, Dansk botanisk Arkiv 15: 113 (1953). (<strong>Pleosporales</strong>, genera incertae sedis) Generic description Habitat terrestrial, saprobic. Ascomata small- to medium-sized, solitary, scattered or in small groups, immersed, globose or subglobose, papilla covered with short and blackish setae, coriaceous. Peridium thin, comprising small heavily pigmented thick-walled cells of textura angularis. Hamathecium of cellular pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, broadly clavate, with a short, furcate pedicel, and small ocular chamber. Ascospores fusoid to narrowly fusoid with narrowly rounded ends, pale brown to reddish brown, multi-transverse septa, usually with one longitudinal septum in some central cells, constricted at the primary septum. Anamorphs reported for genus: none. Literature: Barr 1990b, 1992b; Crivelli 1983; Lumbsch and Huhndorf 2007; Müller 1951; Munk 1953, 1957. Type species Cilioplea coronata (Niessl) Munk, Dansk botanisk Arkiv 15: 113 (1953). (Fig. 23) ≡ Pleospora coronata Niessl, Notiz. Pyr.: 16 (1876). Ascomata 170–290 μm high×200–410 μm diam., solitary, scattered, or in small groups, immersed, globose or subglobose, wall black, papilla raised, 50–80 μm high, with short and blackish setae, coriaceous (Fig. 23a). Peridium 9–15 μm thick laterally, up to 28 μm thick at the apex, thinner at the base, 1-layered, composed of small heavily pigmented thickwalled cells of textura angularis, cells up to 4×2.5 μm diam., cell wall 2–3 μm thick, apex cells smaller and walls thicker (Fig. 23b). Hamathecium of long cellular pseudoparaphyses, 2–3 μm broad. Asci (60-)80–108×10–15 μm (x ¼ 85:3 12:1mm, n=10), 8-spored, bitunicate, fissitunicate, broadly clavate, with a short, thick, furcate pedicel, 5– 15 μm long, and a small ocular chamber (to 3 μm wide× 2 μm high) (Fig. 23c and d). Ascospores 21–27.5×5.5– 7.5 μm (x ¼ 24 6:7mm, n=10), biseriate to uniseriate at base, fusoid to narrowly fusoid with narrowly rounded ends, pale reddish brown, 5–7 transverse septa (mostly 5), usually with one longitudinal septum in some central cells, deeply constricted at the median septum, the part above the primary septum shorter and broader, smooth-walled. Anamorph: none reported. Material examined: GERMANY, Hadiberg. on Reseda lutea Hadiberg, 20 Sept. 1875, Niessl (M 175-89-290, lectotype; M 175-89-291, type). Notes Morphology Cilioplea was introduced by Müller (1951) as a subgenus of Pleospora, and this was followed by Munk (1957), who had earlier proposed it as a separate genus typified by C. coronata based on its hairy papilla, clavate asci as well as its “perfectly paraphysoid” (see Munk 1953). A relatively narrow concept of Pleospora was accepted by Crivelli (1983), and four species was assigned under the separate genus Cilioplea, viz. C. coronata, C. genisticola (Fautrey & Lambotte) Crivelli, C. kansensis (Ellis & Everh.) Crivelli and C. nivalis (Niessl) Crivelli. Subsequently, another six species were added (Barr 1990b, 1992b). Currently, ten species are included under Cilioplea. Phylogenetic study None. Concluding remarks The most striking character of Cilioplea is its setose papilla, which has been shown to have no phylogenetic significance in Lentitheciaceae (Zhang et al. 2009a). Cilioplea was assigned under Lophiostomataceae (Lumbsch and Huhndorf 2007), but there is little morphological similarity with the Lophiostomataceae sensu stricto (Zhang et al. 2009a). Thus its familial placement needs further study. Crivellia Shoemaker & Inderb., in Inderbitzin, Shoemaker, O’Neill, Turgeon & Berbee, Can. J. Bot. 84: 1308 (2006). (Pleosporaceae)
Fungal Diversity Fig. 23 Cilioplea coronata (M 175-89-290, lectotype). a Immersed ascomata in small groups on the host surface (the covering host tissue was removed). b Section of a partial ascoma. Note the thin peridium. c Clavate asci within pseudoparaphyses. d Ascus with a small ocular chamber. Scale bars: a=0.5 mm, b=100 μm, c=50 μm, d=10 μm Generic description Habitat terrestrial, hemibiotrophic or parasitic. Ascomata small- to medium-sized, scattered, immersed, erumpent to nearly superficial, papillate, ostiolate. Peridium thin, composed of two cells types, outer cells of thick walled and textura angularis, inner cells thin-walled, yellow. Hamathecium of dense, long and thin pseudoparaphyses. Asci (4-) 8-spored, bitunicate, fissitunicate dehiscence not observed, broadly cylindrical to cylindrical, with a short, furcate pedicel and an ocular chamber. Ascospores fusoid to broadly fusoid, pale brown, septate, sometimes with one or two vertical septa in the middle cells, constricted at the septa.

Bot. 84: 1308 (2006). (Fig. 24) ≡ Cucurbitaria papaveracea De Not., Sfer. Ital.: 62 (1863). Ascomata 210–260 μm high×300–380 μm diam., densely scattered, immersed, erumpent to nearly superficial, flattened globose, dark brown, papillate, ostiolate (Fig. 24a). Peridium 25–30 μm thick, thicker near the apex and thinner at the base, composed of two cell types, outer cells of thick-walled and textura angularis, cells up to 10× 5 μm diam., cell wall 2–4 μm thick, inner cells thin-walled, yellow (Fig. 24b). Hamathecium of dense, long, 1–2 μm
