Ptychogaster属
The genus Ptychogaster
Ptychogaster属とCeriomyces属に分類されてきた全種について再検討を行い、前者をPostia属の無性世代に限定した。
Abortiporus biennisの無性世代としてSporotrichopsis属を、Sporotrichum azureumに対してCaeruleomyces属をそれぞれ提唱した。
PtychogasterおよびCeriomycesに分類された全種の注釈付きチェックリストを掲載した。

(The fruiting bodies of Sporotrichopsis terrestris are often found in clusters, either grouped together or forming a carpet-like structure. They are partially buried in fallen leaves and grass, with only the upper half visible. The lower half of the fruiting body is usually inclined and yellow, gradually expanding into a round or inverted conical shape. Sometimes, multiple branches of the mycelium produce separate fruiting bodies that fuse together, appearing as a single organism. However, a vertical section reveals the fused nature of these individual entities. The fruiting body does not possess a discernible outer layer, but instead consists of unarmed holes of various sizes and shapes with jagged edges. These holes are the openings of channels or locules in the interior of the fruiting body. The root-like part of the mycelium is composed of slightly branched, non-septate, hyaline hyphae that intertwine in lengthwise fashion to form the fruiting body. Partitions formed by the splitting of hyphae result in elongated and narrow cavities or locules between the hyphal strands. Towards the periphery, these strands become progressively thinner due to continued division. Hyphae without swelling or regular arrangement protrude from the locule walls and produce spore clusters at their tips (possibly also individually on the sides). There is no true hymenium present. In thick layers, the spores appear reddish-brown, while under water they are hyaline with a darker central core. The shape of the spores is not perfectly spherical, with the former attachment point being slightly elongated. The spores have a diameter of 0.004-0.007 mm. The flesh of both the mycelium and its extension into the fruiting body is whitish, tough, and leathery, with a cork-like texture. The mycelium has a typical sponge-like smell. The observation of water droplets on the surface of the fruiting bodies during a rainy period in August, in a grassy area of the Hustarer Forest near Vinkovce, evoked memories of Polyporus dryadeus Bull. Unfortunately, the investigation into the nature of these droplets was not conducted due to the late hour of discovery and their subsequent disappearance. The rapid development of the fungus is evidenced by the fact that not only were there twig debris present, but living grasses were also surrounded by its mycelium. The Ceriomyces terrestris fungus was also encountered in October, at a more advanced stage compared to the initial discovery. It was found at the Kunjevce Forest near Vinkovce, growing at the very bottom on the side of completely decayed white beech logs, with its now lobed roots partially attached to the wood. The old fruiting body was now developed into an elongated bulb, sometimes reaching a height of 1.5 inches, with an uneven surface and no visible canal openings due to blockage. A vertical section revealed a fleshy continuation of the root substance in the axial direction, extending over 3 inches and occupying up to two-thirds of the overall height of the fungus. It resembled a rounded column with the canals radiating towards the periphery. This fruiting body had several spherical white sprouts, measuring 4 to over 6 inches in width, with holes covering the entire surface. These sprouts resembled those found on tubers of Helianthus tuberosus and similar plants. These sprouts exhibited the same structure as described during the initial discovery.)
