“…Several species of the genus, Humicola are rich in organic matter and are able to produce strong cellulolytic enzymes and may have important economical application (White and Downing 1953;Sharma et al 2008;Du et al 2013). Species may also reduce disease caused by Aspergillus flavus, Phytophthora capsici and Alternaria brassicicola (Wicklow et al 1998;Ko et al 2011).…”

Notes on 113 fungal taxa are compiled in this paper, including 11 new genera, 89 new species, one new subspecies, three new combinations and xx reference specimens. A wide geographic and taxonomic range of fungal taxa are detailed. In the Ascomycota the new genera Angustospora (Testudinaceae), Camporesia (Xylariaceae), Clematidis, Crassiparies (Pleosporales genera incertae sedis), Farasanispora, Longiostiolum (Pleosporales genera incertae sedis), Multilocularia (Parabambusicolaceae), Neophaeocryptopus (Dothideaceae), Parameliola (Pleosporales genera incertae sedis), and Towyspora (Lentitheciaceae) are introduced. Newly introduced species are Angustospora nilensis, Aniptodera

“…However, the main breakdown of this material -which is abundantly supplied each fall -should be expected to occur under the natural conditions of the normal environment, the soil, Microorganisms originating from the soil have already been shown to be well-fit for the degradation of cutin (HEINEN & de VRIES 1966). Since other polymer plant products like cellulose are also attacked quite rapidly in the soil by a variety of microorganisms (SIU 1951;WHITE & DOWNING 1953;TRIBE 1957) we tried to follow also the degradation of cuticular components under similar conditions.…”

The cuticular components cellulose and cutin are decomposed in a period of 3-8 months (depending on the season) by soil microorganisms under natural conditions. The cellulose is attacked prior to the cutin layer. The latter is invaded by microorganisms which settle first in the cellulose layer. If purified cutin strips with the cellulose removed, are exposed to the action of soil microorganisms, the degradation also starts from the "inside" of the layer.The progress of degradation depends on the soil used, active garden soil giving the best, and poor sand soil the slowest attack. The degradation of the cutin layers starts with a swelling of the former boundaries of the epidermal cells, then follows the removal of successive sub-layers and finally the detachment of entire subunits from the weakened structure, ultimately leading to a total decay of the structure. The detachment of the lamellae within the cutin layer could be shown in cross sections of the exposed material by electron microscopical examination.Halo-formation around the invading microorganisms, and the lipid accumulation as a result of fatty acid release from the cutin by far-distance decomposition, showed that cutin decay by exo-enzyme action is a widespread property of soil microorganisms.

“…Species of Humicola are widely distributed and common in neutral or alkaline soils (Domsch et al, 1980;White and Downing, 1953). Species in this ge- nus typically inhabit soils high in organic matter, and often are strongly cellulolytic (Barron, 1968).…”

A psychrophilic species of Humicola was isolated that differs physiologically and morphologically from Humicola fuscoatra, to which it bears a resemblance. Based on these characteristics it is described herein as a new species, Humicola marvinii.
