Ascomycete.org, 7 (2) : 45-53. Avril 2015 Mise en ligne le 2/04/2015 Summary: A survey of coprophilous fungi from Italy has allowed the author to recognise nineteen Podospora species, three (P. fimiseda, P. appendiculata and P. perplexens) belonging to section Podospora, whose main morphological features are mentioned and also examined in the light of recent molecular studies. P. appen-diculata and P. perplexens are described for the first time from Italy and compared with P. fimiseda, which has frequently been collected and described by the author. The three species are also compared with others in sect. Podospora, and a key to the section is provided. Species currently excluded from sect. Podospora are also discussed.
... In questo gruppo P. communis presenta, come P. alexandri, un collo liscio e spore di dimensioni estremamente variabili (testa 29-40 x 16-25 µm; pedicello lungo 18-39 µm, Lundqvist, 1972), con code gelatinose tendenti ad agglutinarsi, ma si differenzia per gli aschi e le spore (sia la testa che il pedicello) più piccoli; quest'ultime, tra l'altro, in P. communis possiedono quattro code basali e sono prive di code aggiuntive alla base del pedicello (Spegazzini, 1880;Lundqvist, 1972). Altra differenza sostanziale è che in P. alexandri le code sono scarsamente visibili o non visibili affatto in acqua, mentre in P. communis le code stesse sono facilmente osservabili in acqua, almeno per quanto riguarda la nostra esperienza, derivante dallo studio di sedici collezioni italiane (Doveri et al., 1998(Doveri et al., , 2000Doveri, 2004). Quanto alle altre specie del gruppo, possiamo ricordare insieme P. deropodalis R.S. Khan & Cain (1972), P. euphratica Abdullah (1987), P. hyalopilosa (R. Stratton, 1921) Cain, P. multicaudiculata Cailleux (1969), P. spinulosa R.S. Khan & Cain (1972), dal momento che hanno un pedicello alquanto più corto (ad eccezione di P. deropodalis) e una testa sporale considerevolmente più piccola o più o meno uguale (in P. multicaudiculata) a quella di P. communis, potendo così essere immediatamente distinte da P. alexandri. ...
... In this group P. communis has, like P. alexandri, a smooth neck and spores greatly variable in size (head 29-40 x 16-25 µm; pedicel 18-39 µm long, 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., 1998Doveri et al., , 2000Doveri, 2004). ...
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). Abbreviations: CLSM = author's personal herbarium; d.c. = damp chamber culture; MCVE = Herbarium of Venetian Civic Museum.
