The Atlantic Forest is the better known Brazilian biome regarding polypore diversity. Nonetheless, species are still being added to its mycota and it is possible that the knowledge of its whole diversity is far from being achieved. On the other hand Caatinga is one of the lesser known. However, studies in this biome have been undertaken and the knowledge about it increasing. Based in recent surveys in Atlantic Forest and Caatinga remnants in the Brazilian States of Bahia, Pernambuco and Sergipe, and revision of herbaria, twenty polypore species previously unknown for these states were found. Fuscoporia chrysea and Inonotus pseudoglomeratus are new records to Brazil and nine are new to the Northeast Region. Furthermore, four species previously known from Brazil were found for the first time in the Atlantic Forest, viz. Flabellophora parva, F. chrysea, I. pseudoglomeratus and Trametes lactinea, and three in the Caatinga, viz. I. portoricensis, Phylloporia spathulata and Schizopora flavipora. Keys to the main taxa are provided.

The anamorphic state of Leveillula taurica was found causing a powdery mildew disease on Cleome spinosa in north-eastern Brazil. Its chasmothecial state was not observed on the collected samples. The fungus is illustrated and described. This report represents the first record of this fungus on Cleome spinosa in Brazil.

4. Scleroderma minutisporum, a new earthball from the Amazon rainforest

Authors: Alfredo DS, Leite AG, Braga-Neto R, Cortez VG, Baseia IG

Recieved: 23 March 2012, Accepted: 11 April 2012, Published: 11 May 2012

A new species of earthball, Scleroderma minutisporum was found in the Brazilian Amazon. The specimen, collected in Adolpho Ducke Forest Reserve, Amazonas State, Brazil is named because of the small size of its basidiospores. A description, photographs, and taxonomical comments are provided, and the holotype is compared with related taxa.

5. New species and new records of cercosporoid hyphomycetes from Cuba and Venezuela (Part 1)

Authors: Braun U, Urtiaga

Recieved: 05 April 2012, Accepted: 26 April 2012, Published: 13 May 2012

Numerous cercosporoid leaf-spotting hyphomycetes have been continuously collected in Venezuela and several new species and records have been published. Additional specimens, including various collections made between 1966 and 1970 in Cuba and Venezuela, are treated in this paper. The latter material is now housed at K (previously deposited at IMI as “Cercospora sp.”). Venezuelan collections made between about 1990 and 2012 (most of them since 2006) are now deposited at HAL. Several species are new to Venezuela, some new host plants are included, and the following new species and new varieties are introduced: Cercospora hadroanthi, Passalora emmeorhizae, P. melochiae, Pseudocercospora andirae, P. cordiae-alliodorae, P. cordiigena, P. crescentiae, P. gonolobicola, P. jahnii var. amaculata, P. pehriicola, P. rauvolfiae-tetraphyllae, P. trichophila var. punctata, Zasmidium asclepiadis.The new combinations Pseudocercospora trichophila var. solani-asperi and Zasmidium gongronematis are proposed.

Authors: Cavender JC, Landolt JC, Suthers HB, Stephenson SL

Recieved: 19 April 2012, Accepted: 30 April 2012, Published: 24 May 2012

Surveys for dictyostelid cellular slime moulds (dictyostelids) carried out in various areas of Mexico over the past half century have yielded considerable data on the distribution of these organisms in one region of the Neotropics. The species recovered in these surveys include several forms later described as new to science. The present paper provides a comprehensive overview of what is known about the taxonomy, ecology and distribution of the dictyostelids of Mexico.

Recieved: 24 May 2012, Accepted: 30 May 2012, Published: 30 June 2012

India is rich in Myxomycetes (acellular slime moulds). They are predominantly restricted to high rainfall and humid climatic regions. Following a literature review, a checklist is provided of 373 species of Mxyomycetes, 17 varieties and 4 forms within 50 genera, 11 families and 6 orders. Most records come from the states of Himachal Pradesh, West Bengal, Uttar Pradesh, Bihar, Maharashtra, Karnataka in South India, Jammu and Kashmir.

10. Aseptic cultivation of Coprinus comatus (O. F. Mull.) Gray on various pulp and paper wastes

Authors: Dulay RMR, Parungao AG IV, Kalaw SP, Reyes RG

Recieved: 01 June 2012, Accepted: 19 June 2012, Published: 30 June 2012

The chemical components of pulp and paper wastes from industrial paper mill were analyzed prior to aseptic cultivation. Mycelial running, primordium initiation, fruiting body development, yield and bioefficiency of Coprinus comatus on pulp and paper waste supplemented with rice bran were studied. Chemical analysis revealed that brown paper waste contains 48 ppm of Pb. The fastest mycelia colonization (8 days), primordium initiation (12 days) and fruiting body development (14 days) were realized in substrate composed of pure coarse gray paper waste. However, the highest yield (9.53 g) and biological efficiency (23.96%) were recorded in the formulation containing light blue paper waste + 10% rice bran. The fruiting bodies produced in contaminated paper wastes were detected to consist of 16.15 ppm of Pb. In general, we have successfully demonstrated the cultivation of C. comatus on pulp and paper wastes enriched with rice bran and its ability to absorb Pb from contaminated substrates.

Keywords: biological efficiency – cultivation phases – heavy metals – mycoremediation
