Abstract

The authors provide very detailed information about the systematic changes which recently involved the fimicolous Pezizales and caused, besides, the transfer of family Thelebolaceae from this order to another not yet well identified but placeable among the bitunicate Ascomycota. After having outlined by a dichotomous key the Italian fimicolous species belonging to Pezizales and Thelebolaceae, the authors describe in detail the morphological features of taxa with which they had not dealt in their contributions on fimicolous fungi. But as regards the species described in the previous articles, only the synonyms and data concerning the studied material are supplied.

... Caudae of the pedicel base shorter and narrower than the upper ones, sometimes agglutinated and then scarcely distinguishable from the sheath, probably formed of two strands as their structure is very similar (presence of a lighter, longitudinal line and sometimes of a double number of strands) to that of the upper caudae. Lower cauda more difficult to see, probably single, often appearing as an extension of the pedicel sheath, seemingly having the same structure as the others, almost imperceptible to 50 x 7-9 µm.Doveri et al., 1998Doveri et al., , 2000 Doveri, 2004). nudo, nella prima, inoltre, gli aschi si restringono più distintamente verso l'apice, le dimensioni sporali medie sono maggiori, il pedicello ha una forma assai meno variabile e le code inferiori non sono quasi mai uniche. ...
... Lundqvist, 1972), with caudae tending to agglutinate, but differs in its smaller asci and spores (both spore head and pedicel) which, additionally, have four lower caudae and lack additional caudae at the pedicel base (Spegazzini, 1880; Lundqvist, 1972). Another difference is that in P. alexandri caudae are scarcely visible or unnoticeable in water, whereas in P. communis they are easily observable in water (at least in our experience, which comes from the study of sixteen collections from Italy, Doveri et al., 1998 Doveri et al., , 2000 Doveri, 2004). As to the other species of the group,, 1921; Cain, 1934; Page, 1960; Mirza & Cain, 1969; Cailleux, 1969 Cailleux, , 1971 Lundqvist, 1970 Lundqvist, , 1972 Lundqvist, , 1973 Khan & Cain, 1972; García-Zorrón, 1973; Abdullah, 1987; Krug & Khan, 1989; Lundqvist et al., 1999; Wang, 2000; Lorenzo & Havrylenko, 2001) shows that species of this group preferably grow on equine and bovine dung: in particular most findings of ...

RIASSUNTO-ABSTRACT L'autore descrive le caratteristiche morfologiche di una nuova Podospora raccolta su escrementi di cavallo e la mette a confronto con le specie simili appartenenti alla sez. Malinvernia. The author describes the morphological features of a new Podospora species collected from horse dung and compares it with similar species in sect. Malinvernia.

Sixty one species of coprophilous fungi distributed in 39 genera were recorded from dung of goat, feral donkey and one-humped camel collected from the arid desert areas of the Saint Katherine Protectorate, South Sinai, Egypt. The samples were collected on a monthly basis from October 2012 to March 2013, dried, taken to the laboratory and incubated in moist chambers for 6 to 20 weeks. Morphological features of sporulating ascomycetes were used to characterize and identify the species. Higher number of taxa was observed in feral donkey dung, followed by camel and goat dung. On the generic level, Chaetomium came first, accommodating the highest number of species (7), followed by Fusarium, Pilobolus and Thielavia. Coprinopsis stercorea is apparently a new record for Egypt. Collections are described and the occurrence and distribution of species is discussed, supplemented with a dichotomous key to all reported taxa.

Two Chaetomium species new to Italy, C. brasiliense and C. succineum, are described and an updated key to coprophilous Chaetomium from Italy is provided. All author's collections of 23 species so far known from dung in Italy are listed. Following the recent publications describing new species, the worldwide key to Chaetomium species is updated. Introduction The present update follows Doveri (2008, 2011) and follows the monograph of Doveri (2004) on coprophilous ascomycetes and basidiomycetes from Italy. Doveri (2004) described and keyed out 13 Chaetomium species isolated from a variety of herbivore dung, and briefly redescribed 15 Chaetomium species published after von Arx et al. (1986) study of Chaetomium. Doveri (2008) provided an updated worldwide key to Chaetomium species, based on the monograph of von Arx et al. (1986), and described C. carinthiacum, C. gangligerum, C. homopilatum, C. spinosum, C. subaffine and C. variostiolatum as species new to Italy from dung. The species were illustrated with colour photographs. Doveri (2011) described C. murorum and C. ancistrocladum as new to Italy, and provided a brief update on the genus. Since Doveri (2011), seven new Chaetomium species have been introduced (Asgari & Zare 2011, Ponsuriya et al. 2011). In the present work, the new species are placed in an updated worldwide key. C. succineum and C. brasiliense, isolated from dung are new records for Italy and full descriptions and illustrations are given. A key to 23 coprophilous species so far known from my Italy is also provided. Materials & Methods The two Chaetomium species new to Italy were obtained from different types of dung cultured in non-axenic damp chambers, and studied according to Richardson & Watling (1997) and Richardson (2001), slightly modified by Doveri (2004).

Septal structures of asci, ascogenous hyphae, paraphyses, and excipular cells in the apothecia of six species of Ascobolus, two of Saccobolus, one of Thecotheus, and two of Iodophanus were characterized and assessed for taxonomic value. An electron-opaque, hemispherical structure recognized as the ascoboloid septal type was found in ascal septa of the representatives of Ascobolus, Saccobolus, and Thecotheus. A biconvex band that we recognize as the pezizoid septal type was found in ascal and ascogenous septa of Iodophanus spp. Iodophanus is considered a member of the Pezizaceae based on septal structure and correlated with other microscopic and microchemical features. All genera examined had similar striated bands within septal pores of somatic tissue typical of the type previously described in Peziza.

Morphological and cytological development of a new uniascal species of Lasiobolus is described. Although some of the excipular hairs are atypical of the genus, microscopic and microchemical features of the large operculate ascus, the ascospores, and excipulum are characteristic of known species of Lasiobolus. In culture adjacent mycelial cells function as ascogonia and antheridia. After fertilization the single ascogonial cell enlarges and becomes the ascus. The ascocarp is cleistohymenial, opening shortly before spore liberation. The relationship and evolutionary significance of this species are discussed.

Examination of genera of the Pseudoascoboleae (Ascomycetes, Discomycetes, Ascobolaceae) revealed that many were polytypic. Characters presently used to distinguish these genera are considered to be artificial and true relationships cut across accepted generic lines. Of the genera treated, Thecotheus and parts of Ascophanus, since their asci blue in iodine and their spores bear callose-pectic markings, are considered more closely related to the Pezizeae. Other genera are excluded from the Pseudoascoboleae because of other striking characters. Since the Pseudoascoboleae is shown to be an artificial grouping, it is proposed to abandon the name, using instead the tribe name Theleboleae, placed in the Pezizaceae rather than the Ascobolaceae, for all of those genera with asci that do not blue in iodine, with smooth, elliptical spores without oil guttules, and with eight-spored and multispored species. Four new genera are described: Iodophanus, for species of Ascophanus with iodine-positive asci; Coprotus, for segments of Ascophanus and Ryparobius; Caccobius, for species intermediate to Ascozonus and Thelebolus; and Trichobolus, for the setose members of Thelebolus. The species of Ryparobius not belonging to Coprotus are transferred to Thelebolus.
